Package Unit AC Explained

What Is a Package Unit Air Conditioner and How Does It Work?

A package unit air conditioner - also called a packaged AC unit, packaged HVAC system, or package unit - is the most common whole-home cooling configuration for Los Angeles homes built on slab foundations. Unlike a split system, which divides components between an outdoor condenser and an indoor air handler, a package unit combines every component in a single outdoor cabinet and connects directly to your home's duct system through the rooftop or an exterior wall opening. In Southern California, this configuration is the right solution for a specific set of homes - and the wrong choice for others. Here is what you need to know.

What components are inside a package unit AC?

A package unit AC contains five primary components inside its single outdoor cabinet. The compressor pressurizes refrigerant and drives the cooling cycle. The condenser coil releases heat from the refrigerant to the outside air. The evaporator coil absorbs heat from your home's return air and transfers it to the refrigerant circulating through the system. The air handler or blower draws return air from your home's duct system, passes it across the evaporator coil, and distributes the cooled air through supply ducts to each room. The control board manages the operating sequence, safety shutoffs, and communication with the thermostat. All five components sit in the outdoor cabinet - nothing is installed inside the home other than the ductwork connections and the thermostat.

How does a package unit AC distribute conditioned air through the home?

A package unit connects to your home's existing duct system through a curb-mounted roof penetration or a side-wall plenum connection, depending on the installation configuration. The system draws warm return air from the home through return ducts, cools it across the evaporator coil inside the cabinet, and delivers the conditioned air back through supply ducts to each room. The duct system and thermostat function identically to a split system configuration - the difference is that all of the mechanical components are outdoors rather than split between an outdoor condenser and an indoor air handler.

Is a package unit AC the same as central air conditioning?

Yes - a package unit is a type of central air conditioning. Central air conditioning refers to any whole-home cooling system that distributes conditioned air through a duct network from a central point. A package unit is the configuration where all components are in a single outdoor cabinet. A split system is the configuration where the condenser is outdoors and the air handler is indoors. Both are central AC systems. Both distribute through ductwork. In the Los Angeles residential market, both configurations are common - with package units disproportionately present in slab-construction homes built between the 1950s and 1980s.

Does a package unit AC require ductwork?

Yes - a package unit AC distributes conditioned air through a network of supply and return ducts, exactly like a split system. If your home has existing ductwork in good condition, a package unit is typically the most cost-effective whole-home cooling option for homes where interior mechanical space is not available. If your home has no existing ductwork, a ductless mini split system is typically the better alternative - a package unit installation without existing ductwork requires new duct design and installation at significant additional cost. AIRONE assesses ductwork condition during every free in-home consultation before recommending any system type.

How long does a package unit AC last in Los Angeles?

A package unit AC in Los Angeles typically lasts 12 to 15 years with annual maintenance and 8 to 10 years without, consistent with ACCA service life benchmarks for residential HVAC equipment. Southern California's 7 to 9 month cooling season - significantly longer than the national average of 3 to 4 months according to NOAA historical temperature data for the Los Angeles basin - accelerates compressor wear, coil fouling, and capacitor degradation faster than in cooler climates. Annual maintenance before the cooling season is the most reliable way to extend service life toward the upper end of this range.

Honest System Comparison

Package Unit vs Split System vs Mini Split - Which Is Right for Your Los Angeles Home?

AIRONE installs all three system types and recommends based on your home's specific conditions - not on which system generates higher revenue. Here is the honest comparison for Southern California homeowners.

What is the difference between a package unit and a split system AC?

The core difference is where the components live. A split system separates the outdoor condenser (compressor + condenser coil) from an indoor air handler (evaporator coil + blower) connected by refrigerant lines running through an interior wall or floor. A package unit combines all of these components - compressor, condenser, evaporator, and blower - in a single outdoor cabinet and connects to the duct system through the roof or an exterior wall opening. No components are installed inside the home. The practical implications: split systems are available across a wider efficiency range (14 to 26 SEER2), require an interior mechanical space, and offer more flexibility in equipment selection. Package units top out at approximately 16 SEER2, require no interior space, and are typically less complex to replace like-for-like when the existing ductwork and electrical connections are already configured for a package unit installation.

When is a package unit better than a split system in Los Angeles?

A package unit is typically the better choice in four specific situations. First, when the home is built on a slab foundation with no basement or interior mechanical space - the most common scenario in LA County homes built between the 1950s and 1980s. Second, when the existing ductwork and electrical connections are already configured for a rooftop or ground-mount package unit. Third, when a like-for-like replacement is the most cost-effective path and the existing package unit infrastructure is in good condition. Fourth, when peak energy efficiency is not the primary priority and upfront cost is.

When is a split system better than a package unit in Los Angeles?

A split system is typically the better choice when the home has or can accommodate an interior mechanical space, when higher efficiency is the priority, or when replacing both the AC and heating system simultaneously. Split systems provide access to the full efficiency range from 14 to 26 SEER2, including variable-speed communicating systems with the best humidity control and operating cost performance.

When is a mini split better than a package unit in Los Angeles?

A mini split is typically the better choice when the home has no existing ductwork, when zone-level temperature control is the priority, or when adding cooling to a room addition or ADU that cannot connect to the existing duct system. Package units and split systems both require ductwork - if no existing ducts and installing new ductwork is impractical, a ductless mini split is the right path.

Decision Framework

When Is a Package Unit AC the Right Choice in Southern California?

The most important question at package unit replacement time - one that most Los Angeles contractors answer based on what they stock or what yields the highest margin - is whether a like-for-like package unit replacement is the right call, or whether switching to a split system makes more sense for your specific home. AIRONE answers this honestly, in writing, before any work begins.

Why are package units so common in Los Angeles homes specifically?

Package units are disproportionately common in Southern California relative to other US markets because of one structural fact: the Los Angeles basin has the highest proportion of slab-on-grade construction of any major US metro. A slab home is built directly on a concrete foundation - no basement, and typically limited or no attic space for HVAC equipment. These homes were built without the interior mechanical space that a split system's air handler requires. When the original HVAC system was installed, a package unit was the only practical choice. When the system reaches end of life, a like-for-like package unit replacement is often still the most cost-effective path, because the ductwork, electrical connections, and curb or pad infrastructure are already configured for a package unit. Converting to a split system requires creating an interior mechanical space - often involving attic conversion, closet modification, or garage buildout - and routing new refrigerant lines. This adds $3,000 to $7,000 or more to the project cost in most LA County homes and is only justified when the efficiency upgrade and long-term operating cost savings exceed that premium over the homeowner's planning horizon.

When does a like-for-like package unit replacement make sense?

A like-for-like package unit replacement makes sense when four conditions are present. First, the existing ductwork is in good condition. Second, the existing rooftop curb or ground-mount pad is in good structural condition and compatible with the replacement unit's footprint. Third, the interior space constraints that drove the original package unit selection still apply. Fourth, the homeowner's efficiency and operating cost priorities do not require a variable-speed system - if long-term energy efficiency is the priority, the split system's wider efficiency range (up to 26 SEER2 vs the package unit's 16 SEER2 ceiling) may justify the conversion cost.

When should I consider switching from a package unit to a split system?

Switching from a package unit to a split system makes sense when three conditions align. First, interior mechanical space is available or can be created at reasonable cost. Second, the homeowner plans to stay 7 or more years and wants access to the higher efficiency range available in split systems. Third, the total installed cost of the split system conversion is within a range that the efficiency savings can pay back within the planning horizon. AIRONE provides a written cost comparison of both options - package unit vs split system conversion - as part of every free in-home replacement assessment.

What if a contractor recommended replacing my package unit with a split system?

Get a second opinion before committing to a split system conversion. The conversion involves more labor, more materials, and more subcontracted work than a like-for-like package unit replacement - it is the higher-margin option for the contractor regardless of whether it is the right option for your home. AIRONE provides free second opinions on package unit replacement recommendations. The free assessment includes a written comparison of the package unit replacement cost versus the split system conversion cost, with the efficiency and operating cost implications of each option stated clearly. If the split system is the right choice for your home, AIRONE will tell you that. If it is not, AIRONE will tell you that too.

Installation Process

What Does AIRONE's Package Unit AC Installation Process Look Like?

Every AIRONE package unit installation follows the same process - from the free in-home assessment through the building inspection and post-install documentation. Seven steps. One written quote. No additions to the agreed price.

1

Free In-Home Assessment (45 to 60 minutes)

An AIRONE technician visits the property to assess everything the installation requires. For package units, the assessment covers: home measurement for Manual J load calculation; existing ductwork condition and sizing; electrical panel capacity for the unit's dedicated circuit; rooftop structural capacity and curb condition (for rooftop configurations) or ground-mount clearance and pad condition (for ground-mount); and - critically for replacement jobs - the written comparison of a like-for-like package unit replacement versus a switch to a split system, including total installed cost and efficiency difference for both options. For Los Angeles homes built before 1980 with original 100-amp electrical service, the panel assessment is important - older panels frequently require upgrade to support a modern unit's dedicated circuit.

2

Manual J Load Calculation (included in assessment)

Every AIRONE package unit installation begins with a Manual J load calculation using ACCA-approved software and actual home measurements - not a square footage rule of thumb. According to ACCA, up to 50% of residential HVAC systems in the United States are incorrectly sized, the majority being oversized. An oversized package unit short cycles, preventing adequate humidity removal, wasting electricity, and causing premature compressor wear. AIRONE does not recommend a replacement size without Manual J, and does not replace like-for-like without verifying the previous system was correctly sized.

3

Written Quote with Options (delivered same visit)

The written quote covers the full scope: unit, ductwork connections, electrical, condensate, thermostat, curb or pad work if needed, permit fees, haul-away and disposal of the old system, installation labor, commissioning and testing, and post-install inspection coordination. For replacement jobs, the quote includes both the package unit replacement option and the split system conversion option with itemized costs. No line items appear on the invoice that were not on the signed quote.

4

Permit Filing (3 to 10 business days in most LA County cities)

Under California Building Code Section 17920.9, a permit is required for package unit AC installation and replacement across most cities in LA County and Orange County. AIRONE files the permit application, pays the fees as part of the quoted installation cost, and manages the entire permit process. Rooftop installations may require an additional structural review from the building department - AIRONE handles this documentation.

5

Site Preparation - Rooftop or Ground Mount

Rooftop installations: AIRONE verifies rooftop structural capacity, installs or verifies the existing curb mount, confirms ductwork penetration alignment, and coordinates crane services where required for units that cannot be lifted by hand.

Ground-mount installations: AIRONE verifies or installs a concrete pad at grade level, confirms adequate clearances on all sides per manufacturer specifications, and verifies the ductwork connection approach through the exterior wall.

6

Installation Day (one full day for standard replacement)

A standard like-for-like package unit replacement in a home with existing ductwork and connections typically takes one full day - 6 to 8 hours for a two-technician crew. Installations requiring new ductwork, rooftop curb modification, electrical panel upgrade, or ground-mount pad installation may require additional time. AIRONE provides a timeline estimate at scheduling confirmation.

7

Commissioning, Building Inspection, and Post-Install Support

After installation, the system is commissioned before the technician leaves: refrigerant charge verified against manufacturer specifications, supply air temperature differential measured, airflow confirmed at all registers, thermostat response tested, and condensate drainage verified. A written commissioning report is provided. AIRONE schedules and is present for the required building inspection and provides manufacturer warranty registration, all permit documentation, and a post-install walkthrough covering thermostat programming and filter schedule.

Seven steps. One written quote. No surprises. Call (323) 471-1037

Package Unit Configurations

Package Unit AC Types - All-Electric, Gas/Electric, Package Heat Pump, Rooftop, Ground-Mount

Package units are not all alike. There are three configurations based on how heating is delivered, and two installation configurations based on where the unit is placed. AIRONE installs all five configurations across LA County, South Bay, and OC.

What is an all-electric package unit?

An all-electric package unit provides cooling from an electric compressor and heating from electric heat strips - resistance heating elements inside the cabinet that warm the air before it circulates through the ducts. This is the most common residential package unit configuration in Southern California for three reasons: LA's mild heating season (approximately November through February per NOAA climate data) rarely stresses electric heat strips; California's push toward residential electrification favors all-electric configurations; and all-electric units typically cost less upfront than gas/electric alternatives. For most LA County, South Bay, and Orange County homes, an all-electric package unit is the right configuration.

What is a gas/electric package unit and when does it make sense in Los Angeles?

A gas/electric package unit provides cooling from an electric compressor and heating from a gas burner inside the same cabinet - the gas line connects to the package unit at the roof curb or ground mount location. In most of Los Angeles, a gas/electric package unit is not necessary - LA's mild winter climate means electric heat strips perform adequately. Gas/electric is appropriate in two specific situations: in Antelope Valley cities - Lancaster, Palmdale, and surrounding areas - where winter temperatures can drop into the 20s and 30s Fahrenheit and electric heat strips can struggle during extended cold snaps; and in homes where existing gas infrastructure is connected to the package unit location and gas heating has historically been the preferred configuration. AIRONE confirms whether gas/electric is warranted based on your location and home before recommending it.

What is a package heat pump and how is it different from a standard package unit?

A package heat pump is a single outdoor cabinet that provides both cooling and heating using the same refrigerant cycle - reversing direction to extract heat from outside air during cooler months rather than relying on electric heat strips or a gas burner. In Southern California's mild heating climate, a package heat pump is typically 2 to 3 times more energy-efficient for heating than either electric heat strips or gas heating, because it moves heat rather than generating it. Package heat pump systems qualify for the federal $2,000 IRS Form 5695 tax credit under the Inflation Reduction Act, making them the most financially compelling package unit configuration for homeowners replacing both their AC and heating system simultaneously. AIRONE handles AHRI certification and all rebate documentation on package heat pump installations.

What is a rooftop package unit installation?

A rooftop package unit is mounted on a raised curb on the roof of the home, with ductwork penetrations through the roof connecting the unit to the home's duct system. Rooftop is the more common configuration for single-story slab homes in Los Angeles. Requirements: verification of roof structural capacity; installation of a properly flashed curb mount; ductwork penetration alignment; crane coordination for heavier units. AIRONE handles all structural review, curb work, and crane coordination as standard parts of every rooftop installation. Note: light commercial rooftop RTU service → see Commercial HVAC.

What is a ground-mount package unit installation?

A ground-mount package unit is installed on a concrete pad at grade level alongside the home - typically in a side yard or rear yard. Requirements: concrete pad at grade level; adequate clearances on all sides (typically 24 inches minimum on service sides); exterior wall plenum connection to the duct system; appropriate electrical and refrigerant connections. AIRONE installs and repairs the concrete pad as a standard part of ground-mount installations where the existing pad requires replacement.

Every AIRONE package unit quote includes: the outdoor cabinet unit, ductwork connections and transitions, electrical connections and dedicated circuit verification, condensate connections where applicable, thermostat, permit filing and fees, haul-away and disposal of the old unit, installation labor, commissioning and testing, and post-install building inspection coordination. No line items appear on the invoice that were not on the written quote signed before work began.

Does a package unit AC increase home value in Los Angeles?

Yes - according to the National Association of Realtors, central air conditioning ranks among the top features Southern California buyers expect. A permitted, inspected package unit installation with documented service history removes a common home inspection contingency trigger. Homes without whole-home cooling in the LA market are consistently priced lower to reflect the anticipated installation cost.

What rebates are available for package unit AC installation in Los Angeles?

Southern California homeowners may qualify for SCE rebates for qualifying high-efficiency package units, LADWP rebates for qualifying units, and the federal $2,000 IRS Form 5695 tax credit for qualifying package heat pump installations under the Inflation Reduction Act. AIRONE identifies all applicable rebates during the quote process and provides documentation to support rebate applications.

SEER2 Efficiency

Package Unit AC Efficiency - SEER2 Ratings, Rebates, and Why the Range Is Narrower

Package units are available from 14 SEER2 (federal minimum for California) to approximately 16 SEER2 - a narrower range than split systems, which reach 26 SEER2. This matters for long-term operating cost decisions.

Why do package units have a lower SEER2 ceiling than split systems?

The efficiency ceiling for package units is approximately 16 SEER2, compared to 26 SEER2 for the highest-efficiency split systems. The reason is physical: in a package unit, the condenser coil - which must release heat to the outside air to complete the cooling cycle - shares the outdoor cabinet with the compressor and evaporator. The condenser's heat rejection is limited by the cabinet geometry and the ambient heat that surrounds all components. In a split system, the outdoor condenser unit stands alone with optimal airflow clearances on all sides, allowing significantly more efficient heat rejection at the same outdoor temperature. This is not a design flaw - it is a fundamental consequence of combining all components in a single cabinet.

Is minimum efficiency (14 SEER2) right for my package unit?

Lowest upfront cost, highest long-term operating cost within the package unit range.

Right for you if: budget is the primary constraint, you plan to sell within 5 years, or the property is a rental where energy savings accrue to a tenant rather than the owner.

Is mid efficiency (15–16 SEER2) right for my package unit?

The best value tier for most Southern California homeowners choosing a package unit. Upgrading from 14 to 16 SEER2 typically reduces cooling energy consumption by 12 to 17% in SoCal's 7 to 9 month cooling season. The upgrade premium over minimum efficiency is typically $500 to $1,500 and pays back within 3 to 5 years per NOAA cooling season data.

Right for you if: you plan to stay 5 or more years, want SCE or LADWP rebate eligibility, or want meaningful energy savings.

Should I consider a split system if efficiency is a priority?

If long-term energy efficiency is the top priority, the split system's efficiency range - up to 26 SEER2 with variable-speed communicating systems - delivers operating cost advantages that a package unit cannot match. The decision is whether the additional installation cost of a split system conversion is justified by the efficiency savings over your planning horizon. AIRONE provides a written comparison of both options during the free assessment.

Permits + Title 24

Does Package Unit AC Installation Require a Permit in Los Angeles?

Yes - a permit is required for package unit AC installation and replacement in most cities across Los Angeles County and Orange County.

What is the permit requirement for package unit AC installation in California?

Under California Building Code Section 17920.9 and related HVAC installation standards, a permit is required for package unit AC installation - both new installations and replacements - across most cities in the AIRONE service territory. The permit triggers a building inspection verifying California Building Code requirements for electrical connections, structural mounting, clearances, and Title 24 energy efficiency standards. AIRONE includes permit filing, fees, and inspection coordination in every package unit installation quote as a standard line item.

Are there additional permit requirements for rooftop package unit installations?

Yes - rooftop installations in most LA County and Orange County cities require a structural review component confirming the roof can support the combined dead load of the unit and the curb mount. AIRONE assesses structural readiness during the free in-home assessment and includes any required documentation in the permit application - not a separate charge.

What is Title 24 and how does it apply to package unit installations?

Title 24 is California's Building Energy Efficiency Standards - the most stringent residential energy code in the United States. For package unit installations, Title 24 requires minimum SEER2 ratings, duct leakage testing where applicable, thermostat programmability and demand response capability, and documentation signed by the licensed installing contractor. All AIRONE package unit installations are Title 24 compliant.

What are the risks of installing a package unit without a permit in Los Angeles?

Four specific risks: (1) insurance claim denial if a related fire or property damage claim arises; (2) disclosure obligations in a property sale requiring remediation before closing; (3) voided manufacturer warranty; (4) home inspection liability regardless of system condition. AIRONE includes permit filing in every package unit installation - it is a standard part of the scope, not an upsell.

Why AIRONE

Why Los Angeles Homeowners Choose AIRONE for Package Unit AC

Does AIRONE give me an honest comparison of package unit vs split system options?

Yes - every AIRONE package unit replacement assessment includes a written comparison of both options: the like-for-like package unit replacement cost and the split system conversion cost, with the efficiency and operating cost implications of each stated clearly. If the split system is the right choice for your home, AIRONE will recommend it and explain why. If the package unit replacement is the better path, AIRONE will tell you that. The recommendation is based on your home's specific conditions and your financial interests - not on which option generates more revenue for AIRONE.

Does AIRONE perform Manual J load calculation before sizing the package unit?

Yes - every AIRONE package unit installation begins with a Manual J load calculation using ACCA-approved software and actual home measurements. We do not size by rule of thumb or replace like-for-like without verifying the previous system was correctly sized. According to ACCA, up to 50% of residential HVAC systems are incorrectly sized - an oversized package unit short cycles and never manages humidity properly.

★★★★★

Our house in Glendale was built in 1968 - slab construction, no attic space for an air handler. Every contractor we called recommended a package unit without explaining why. AIRONE was the first to actually explain the slab-construction issue, show us the cost comparison between a package unit and what it would take to retrofit a split system, and let us make an informed decision. We went with the package unit. Correct call, correct price, permitted and inspected.

David K., Glendale - Package Unit AC Replacement
★★★★★

Had three contractors recommend replacing our rooftop package unit in Pasadena with a split system. Called AIRONE for a second opinion. They ran the Manual J, confirmed our unit was oversized by half a ton, and showed us in writing that a correctly sized like-for-like package unit replacement was $2,800 less than the split system conversion those contractors quoted. We didn't need a split system - we needed the right package unit. AIRONE installed it for exactly the quoted price.

Christine M., Pasadena - Package Unit AC Replacement
★★★★★

We're in Hermosa Beach - two blocks from the water. AIRONE installed a new package unit and was the only contractor who mentioned the marine-grade coil coating before we did. They cited the ASHRAE data, showed it as a line item, and let us choose. The single outdoor cabinet means one coating covers everything. Our previous unit corroded in 7 years. This one looks perfect at three years in.

Patricia L., Hermosa Beach - Package Unit AC Installation
★★★★★

Live in the Antelope Valley - Lancaster. Our old package unit was gas/electric and I was told we'd need another gas/electric because of our winter temperatures. AIRONE confirmed this and explained why gas heat actually makes sense for our area in a way no other contractor had bothered to do. They knew the Antelope Valley climate, sized it correctly for our heat loads, and the new system has handled every summer we've thrown at it.

Frequently Asked Questions

Package Unit AC Los Angeles - Frequently Asked Questions

A package unit air conditioner is a single outdoor cabinet that contains every HVAC component - compressor, condenser coil, evaporator coil, and air handler - and connects directly to your home's duct system to deliver conditioned air throughout the house. Unlike a split system, which separates the outdoor condenser from an indoor air handler, a package unit has nothing installed inside the home other than the ductwork connections and the thermostat. Package units are the most common whole-home cooling configuration for Los Angeles homes built on slab foundations, where no interior mechanical space is available for a split system's indoor unit. AIRONE installs and replaces package unit AC systems across Los Angeles County, South Bay, and Orange County. CA License #114807. Call (323) 471-1037.
Yes - a package unit is a type of central air conditioning. Central air conditioning refers to any whole-home cooling system that distributes conditioned air through a duct network from a central point. A package unit is the configuration where all components are in a single outdoor cabinet. A split system is the configuration where the outdoor condenser and indoor air handler are separate units. Both are central air conditioning systems, and both use ductwork. In the Los Angeles residential market, package units are disproportionately common in slab-construction homes where there is no interior space for a split system's air handler.
Yes - a package unit AC distributes conditioned air through a network of supply and return ducts, exactly like a split system. If your home has existing ductwork in good condition, a package unit is typically the most cost-effective whole-home cooling option for homes without interior mechanical space. If your home has no existing ductwork, a ductless mini split system is typically the better alternative. AIRONE assesses ductwork condition during every free in-home assessment before recommending any system type.
The fundamental difference is where the components are located. A package unit combines all components - compressor, condenser, evaporator, and blower - in a single outdoor cabinet, with nothing installed inside the home except ductwork connections and the thermostat. A split system separates the outdoor condenser from an indoor air handler connected by refrigerant lines. Practical implications: split systems are available from 14 to 26 SEER2; package units top out at approximately 16 SEER2. Package units require no interior mechanical space; split systems do. AIRONE installs both and provides a written comparison of both options at every assessment.
A package unit is the better choice in four specific situations: when the home is built on a slab foundation with no basement or interior mechanical space for a split system's air handler; when existing ductwork, electrical connections, and rooftop or ground-mount infrastructure are already configured for a package unit; when a like-for-like replacement is the most cost-effective path; and when peak energy efficiency is not the primary priority and access to the split system's higher efficiency range would not justify the added cost of converting.
A package unit uses ductwork to distribute conditioned air throughout the home from a single outdoor cabinet - one thermostat, whole-home uniform temperature. A mini split installs without ductwork, with individual wall-mounted indoor units in each room or zone operating independently. Package units are right for homes with existing ductwork and whole-home cooling needs. Mini splits are right for homes without ductwork, room additions, or homeowners who want zone-level control.
The right choice depends on interior mechanical space availability, efficiency priorities, and the cost comparison of both options. A like-for-like package unit replacement makes sense when no interior space is available, existing infrastructure is in good condition, and the efficiency premium of a split system does not justify the conversion cost. A split system conversion makes sense when interior mechanical space is available or can be created at reasonable cost, you plan to stay 7 or more years, and long-term efficiency savings (up to 26 SEER2 vs 16 SEER2 ceiling) justify the additional installation cost. AIRONE provides a written cost comparison of both options during every free replacement assessment. Call (323) 471-1037.
Package unit AC in Los Angeles typically costs $4,500 to $6,500 for standard efficiency (14 SEER2) ground-mount replacement, $5,500 to $7,500 for standard efficiency rooftop installation, $5,500 to $7,500 for mid-efficiency (15–16 SEER2) ground-mount, $5,000 to $8,000 for gas/electric configurations, and $5,500 to $9,000 for package heat pump systems. Homes requiring electrical panel upgrades add $1,500 to $4,000; rooftop structural prep adds $500 to $2,000 where needed. All prices include permit, haul-away, labor, and commissioning. AIRONE provides a free written quote. Call (323) 471-1037.
Yes. Southern California homeowners may qualify for SCE rebates for qualifying high-efficiency package unit installations, LADWP rebates for qualifying systems, and the federal $2,000 IRS Form 5695 tax credit for qualifying package heat pump installations under the Inflation Reduction Act. AIRONE identifies all applicable rebates during the free assessment and provides all documentation required for rebate applications.
Yes. Under California Building Code Section 17920.9, a permit is required for package unit AC installation - both new installations and replacements - in most cities across Los Angeles County and Orange County. The permit triggers a building inspection verifying compliance with California Building Code and Title 24 energy efficiency standards. Rooftop installations may require additional structural review documentation. AIRONE includes permit filing, permit fees, and inspection coordination in every package unit quote as standard line items - you do not manage any part of the permit process.
A standard like-for-like package unit replacement in a home with existing ductwork and connections typically takes one full day - 6 to 8 hours for a two-technician crew. Installations requiring new ductwork, rooftop curb preparation, crane coordination, or electrical panel upgrade may require additional time. AIRONE provides a specific timeline estimate at scheduling confirmation.
Yes - rooftop package unit installation is common in Southern California, particularly for slab-construction homes where the rooftop provides the most accessible location. Rooftop installation requires verification of roof structural capacity, curb mounting, and ductwork penetration through the rooftop. Crane coordination is required for units that exceed manual placement weight capacity. AIRONE assesses rooftop suitability during the free in-home assessment and handles all structural documentation, curb work, and crane coordination as standard parts of the installation process.
A gas/electric package unit provides cooling from an electric compressor and heating from a gas burner, both in a single outdoor cabinet. In most of Los Angeles, an all-electric package unit is adequate - LA's mild winter climate means electric heat strips perform adequately for most homes. Gas/electric is appropriate in Antelope Valley cities (Lancaster, Palmdale) where winter temperatures can reach the 20s and 30s Fahrenheit, and in homes with existing gas infrastructure where gas heating has historically been preferred. AIRONE confirms whether gas/electric is warranted based on your location.
A package heat pump is a single outdoor cabinet that provides both cooling and heating using the refrigerant cycle - reversing direction to extract heat from outside air during cooler months rather than using electric heat strips or a gas burner. In Southern California's mild heating climate, a package heat pump is typically 2 to 3 times more energy-efficient for heating than either heat strips or gas heat. Package heat pump systems qualify for the federal $2,000 IRS Form 5695 tax credit under the Inflation Reduction Act. AIRONE installs package heat pumps across all service areas and handles AHRI certification and rebate documentation.
A rooftop package unit is mounted on a raised curb on the roof with ductwork penetrations through the rooftop connecting to the home's duct system. A ground-mount package unit is installed on a concrete pad at grade level alongside the home, connecting to the duct system through an exterior wall. Both use identical HVAC components inside the cabinet. The installation configuration is determined by the home's architecture, rooftop accessibility and structural capacity, and available side or rear yard clearance.
Yes - package units have a lower maximum efficiency ceiling. Package units are available from 14 to approximately 16 SEER2; split systems from 14 to 26 SEER2. The reason is physical: all components in a package unit share a single outdoor cabinet exposed to ambient heat, limiting how efficiently the condenser can reject heat. In a split system, the outdoor condenser unit stands alone with optimal airflow clearances. For Southern California homeowners where a package unit is the right choice based on interior space constraints, the 14 to 16 SEER2 range delivers adequate efficiency for the cost.
For most Southern California homeowners choosing a package unit, a 15 to 16 SEER2 mid-efficiency system provides the best balance of upfront cost and long-term savings, paying back the upgrade premium in 3 to 5 years in SoCal's extended cooling season. Homeowners staying fewer than 5 years or managing a rental may find 14 SEER2 more economical. The package unit's efficiency ceiling at 16 SEER2 means there is no premium tier above mid-efficiency within this category - unlike split systems where variable-speed systems at 20+ SEER2 offer a meaningful additional upgrade.
Replace your package unit when one or more of these conditions apply: the system is 12 years or older and facing a major repair; the repair cost exceeds 50% of a comparable new system using the $5,000 rule referenced by Consumer Reports; the system uses R-22 refrigerant and has a refrigerant leak (R-22 is no longer manufactured); or recurring repairs over 2 to 3 years have reached $1,000 to $1,500. In Southern California's 7 to 9 month cooling season, these thresholds are more financially compelling than in cooler climates because degrading efficiency costs more over a longer operating period.
