Section 2 - Replacement Triggers

How Do You Know When AC Replacement Is the Right Decision?

Is a 12–15 year old AC system worth replacing?

Yes - a central AC system in Southern California typically lasts 12–17 years with annual maintenance and 8–10 years without, according to industry service life data. A system at or past 12 years is approaching the end of its cost-effective service life regardless of whether it is currently running. At this age, the next major component failure - compressor, condenser coil, or heat exchanger - typically costs more to repair than the remaining value the system will provide before the next failure.

Does a repair cost that exceeds 50% of a new system mean I should replace?

Yes - if the repair your technician has quoted costs more than half the price of a comparable new system, replacement almost always delivers better long-term value. A $2,000 compressor replacement on a 13-year-old system is the mechanical equivalent of putting a new engine in a car with 200,000 miles - the component is fixed but every other aging part remains in place. AIRONE provides a free replacement quote alongside any repair quote over $800 so you can compare both options before committing.

Should I replace an AC system that uses R-22 refrigerant?

Yes - R-22 was phased out of US production in 2020 under EPA regulations. R-22 supplies are finite, increasingly scarce, and significantly more expensive than modern refrigerants. If your system uses R-22 and develops a refrigerant leak, the cost of recovery, recharge, and leak repair will likely exceed the cost of replacement within the next 1–2 service events. An R-22 system cannot be converted to R-410A or R-454B - replacement is the only long-term solution.

Does the $5,000 rule indicate I should replace my AC?

Yes - multiply your system's age in years by the cost of the repair your technician has quoted. If the result exceeds $5,000, replacement typically delivers better long-term value - a framework referenced by Consumer Reports and widely used by HVAC industry associations. A 12-year-old system facing a $500 repair scores 6,000 - replacement territory. A 6-year-old system facing a $600 repair scores 3,600 - repair territory.

Do rising energy bills mean my AC system needs to be replaced?

Yes - a central AC system losing efficiency draws more electricity to deliver the same cooling output. If your SCE or LADWP bill has increased noticeably over the past 1–2 summers without a change in usage habits, declining AC efficiency is likely contributing. According to NOAA historical temperature data for the Los Angeles basin, SoCal's cooling season runs 7–9 months - significantly longer than the national average of 3–4 months - meaning efficiency losses compound faster here than in cooler climates. Modern high-efficiency replacement systems with SEER2 ratings of 16–20+ can reduce cooling energy consumption by 20–40% compared to a 12-year-old system.

Does a pattern of recurring repairs mean I should replace my AC?

Yes - recurring repairs are a reliable indicator that a system is entering component failure cascade. Each repair addresses one failing part while leaving every adjacent aging component in place. When the repair history over 2–3 years approaches $1,000–$1,500, replacement economics typically favor a new system. AIRONE technicians provide a full written repair history summary and replacement recommendation when a system shows a recurring failure pattern.

Does an AC system that cannot reach setpoint temperature need to be replaced?

It depends - but in most cases involving systems over 10 years old, yes. A system that runs continuously during a 95–105°F day in the San Fernando Valley or Inland Empire but cannot reach the thermostat setpoint has either lost significant capacity, was incorrectly sized originally, or both. In SoCal's 7–9 month cooling season - according to NOAA historical temperature data - a system that cannot maintain comfort at peak conditions is not functioning as designed. Replacement with a correctly sized system eliminates this failure mode entirely.

Get a Free Replacement Quote →

Should I replace an AC system that makes persistent noise despite repairs?

Yes - in most cases involving older systems. Persistent banging, rattling, or grinding from a system that has been inspected and repaired - particularly if the noise originates from the compressor - typically indicates internal compressor wear that is not economically repairable on systems over 10 years old. A compressor replacement on an older system costs $1,200–$2,800 and does not address the age of any surrounding components. The same investment applied toward a new replacement system eliminates the compressor risk and every other aging component simultaneously.

Section 3 - Repair vs Replace

Is It Better to Repair or Replace Your AC System in Los Angeles?

The short answer: Replace your AC when two or more of these four conditions apply - the system is over 12 years old, the repair cost exceeds 50% of a comparable new system, the system uses R-22 refrigerant, or recurring repairs over 2–3 years have reached $1,000–$1,500. If only one condition applies, repair is usually the right call.

This is the most important financial decision on this page - and the one where most homeowners want a straight answer rather than a sales pitch. AIRONE's answer depends on four variables specific to your system and your situation.

Variable 1 - How old is your system?

Age is the most reliable single predictor of replacement value. Systems under 8 years old with a single component failure almost always make more financial sense to repair. Systems over 12 years old with any major component failure - compressor, condenser coil, evaporator coil - almost always make sense to replace. The 8–12 year range is where the other three variables determine the right answer.

Variable 2 - What does the repair cost as a percentage of replacement?

AIRONE uses the 50% rule - referenced by Consumer Reports - as the primary financial threshold: if the repair costs more than 50% of a comparable new replacement system, replacement delivers better long-term value in virtually every scenario. A $2,500 repair on a system where replacement costs $5,000 is the financial equivalent of buying the system twice - once at full price and once through repair costs - without the efficiency gains, warranty protection, or reliability of new equipment.

Variable 3 - What refrigerant does your system use?

R-22 systems face a different calculus than R-410A systems. Because R-22 cannot be converted and its supply is permanently finite, an R-22 system that requires refrigerant service should be evaluated for replacement regardless of age - particularly in Southern California where the long cooling season makes refrigerant-related wear more likely than in cooler climates.

Variable 4 - What is your system's repair history?

A system's repair history over the past 2–3 years is the second most reliable predictor of future failure frequency. A system that has required $1,500 in repairs over 3 years - even if each individual repair was technically justified - is demonstrating a failure cascade pattern that replacement resets entirely.

The honest answer:

If your system scores replacement on two or more of these four variables, AIRONE will tell you that replacement makes more financial sense - and provide a written quote before you commit to anything. If your system scores repair on three or more variables, AIRONE will tell you that too. AIRONE technicians do not earn more by recommending replacement over repair. The recommendation is based on the math, not the margin.

Section 4 - Replacement Process

What Does AIRONE's AC Replacement Process Look Like From Start to Finish?

Step 1 - Free Assessment (45–60 minutes): What does the free AC replacement assessment include?

An AIRONE technician visits your home to assess the existing system - its age, condition, refrigerant type, repair history, and current performance readings. The assessment includes inspection of existing ductwork, electrical panel capacity, and installation location. If the assessment confirms replacement is the right call, AIRONE delivers a written quote before leaving. The assessment is free with no obligation to proceed.

To help the assessment go faster: locate your breaker panel, note the age of your existing system if known (label is on the outdoor unit), and write down any symptoms your current system has shown in the past year. None of this is required - AIRONE identifies everything on-site - but having it ready saves 10–15 minutes.

Step 2 - Written Quote (same visit): What is included in AIRONE's replacement quote?

The written replacement quote covers the full scope - new equipment, refrigerant line set, electrical connections, condensate drain, permit filing and fees, removal and disposal of the old system, installation labor, system commissioning and testing, and post-install inspection coordination. No line items appear on the invoice that were not on the written quote.

Step 3 - Old System Removal (included): What happens to the old AC system?

AIRONE removes and disposes of the existing system as part of every replacement. Old refrigerant is recovered and disposed of in compliance with EPA Section 608 regulations. Haul-away is included in the replacement quote at no additional charge - you do not arrange separate disposal.

Step 4 - Permit Filing (3–10 business days): Does AIRONE file the permit for AC replacement?

Yes - AIRONE files the required building permit with your city or county before replacement begins. Most LA County cities process AC replacement permits within 3–10 business days - some offer over-the-counter same-day approval for like-for-like replacements. AIRONE is familiar with building department requirements across all LA County, South Bay, and Orange County jurisdictions and files permits correctly the first time to avoid revision delays. Permit fees are included in the written quote.

Every AIRONE replacement is permitted and inspected - no exceptions. Call (323) 471-1037 →

Step 5 - Installation Day (6–8 hours): How long does AC replacement take?

One full day for most standard replacements - 6–8 hours for a two-technician crew on a like-for-like central AC replacement with existing ductwork. Replacements requiring ductwork repair or electrical panel upgrades may take one to two days. AIRONE provides a specific timeline estimate when scheduling your replacement appointment.

Step 6 - System Commissioning (30–45 minutes): How does AIRONE verify the new system is working correctly?

After installation, the replacement system is commissioned and verified before the technician leaves - refrigerant charge verified against manufacturer specs, supply and return air temperature differential measured, airflow confirmed at all registers, thermostat response tested, and condensate drainage verified. You receive a written commissioning report with all measurements taken.

Step 7 - Post-Install Support (30 minutes): What does AIRONE provide after the replacement is complete?

After the building inspection passes, AIRONE provides a written job completion report, manufacturer warranty registration, and a full system walkthrough - thermostat programming, filter replacement schedule, and what to watch for in the first 30 days. AIRONE remains reachable at (323) 471-1037 for any post-replacement questions.

Every AIRONE replacement is permitted, inspected, and documented. An unpermitted AC replacement in California can create complications with homeowner's insurance, property sales, and future warranty claims. Call (323) 471-1037 for a free replacement assessment.

Section 5 - Replacement Cost

How Much Does AC Replacement Cost in Los Angeles?

AC replacement cost in Los Angeles varies based on system type, efficiency tier, home size, existing infrastructure condition, and your city's permit requirements. AIRONE provides free written quotes with no obligation. Here is what to expect in 2026.

System Type From To
Central split system - standard efficiency (14–16 SEER2)Like-for-like replacement with existing ductwork $4,000 $7,000
Central split system - high efficiency (17–20 SEER2)Two-stage or variable-speed upgrade $6,000 $10,000
Central split system - premium efficiency (21+ SEER2)Variable-speed communicating systems $9,000 $14,000
Package unit replacement - standardRooftop or ground-level $4,500 $7,500
Ductless mini-split - single zone replacementOne-for-one zone replacement $3,000 $5,500
Heat pump system - full replacementReplaces both AC and furnace $5,500 $12,000
Ductwork repair or partial replacementWhen existing ducts require work before new system $1,500 $5,000
Electrical panel upgrade (if required)Required in some older LA County homes $1,500 $4,000

All prices reflect Los Angeles market ranges for equipment and labor as of 2026. Your exact cost depends on home size, brand, efficiency tier, existing ductwork and electrical condition, and permit fees in your city. AIRONE provides a written flat-rate quote before any work begins - you are never charged more than the approved amount.

What is included in the replacement price?

Every AIRONE replacement quote includes new equipment, refrigerant line set, electrical connections, condensate drain, permit filing and fees, haul-away and disposal of the old system, installation labor, commissioning and testing, and post-install building inspection coordination. No line items appear on your invoice that were not on the signed quote.

Does replacing AC increase home value in Los Angeles?

Yes - a modern, high-efficiency AC system with a valid permit and inspection record is a documented selling point in the Los Angeles real estate market. It removes a common home inspection contingency trigger and reduces buyer negotiation leverage on HVAC condition. An aging system - particularly one using R-22 or one without maintenance records - is a documented liability in a sale transaction that typically results in price reductions or repair credits that exceed the cost of proactive replacement.

Rebates and tax credits that reduce replacement cost:

California homeowners may qualify for SCE rebates up to $1,000 for qualifying high-efficiency replacement systems · LADWP rebates for qualifying systems · SoCalGas rebates when replacing a gas-electric combination · Federal IRS Form 5695 tax credit - $2,000 maximum for qualifying heat pump replacements under the Inflation Reduction Act. AIRONE identifies all applicable rebates during the replacement quote and provides documentation to support applications.

Financing available:

AIRONE offers financing for all AC replacements - 0% APR for qualifying customers, monthly payments starting under $100/month on qualifying systems. When your system fails unexpectedly, financing means you are not choosing between comfort and cash. Subject to credit approval. Call (323) 471-1037 for current terms.

Section 6 - What to Replace With

What Should You Replace Your Old AC System With?

Replacement is an opportunity - not just a necessity. Choosing the right replacement system for your home's specific conditions, efficiency goals, and budget determines your energy costs and comfort for the next 12–17 years.

Is like-for-like AC replacement ever the right choice?

Yes - in three specific situations: when the existing system was correctly sized for the home using Manual J methodology, when the existing ductwork is in good condition and the correct size for the new system, and when budget constraints make the efficiency upgrade premium unworkable. In all other situations, replacement is an opportunity to correct any previous sizing or equipment errors. AIRONE identifies which situation applies to your home during the free assessment.

When does upgrading to a higher-efficiency replacement system make sense?

For most Southern California homeowners, the upgrade from minimum efficiency (14–15 SEER2) to mid-efficiency (16–18 SEER2) makes financial sense at replacement time. The upgrade premium is typically $500–$1,500 - and in SoCal's 7–9 month cooling season, that premium pays back in 3–5 years through lower SCE or LADWP bills. At replacement time - when the labor cost is already sunk - the incremental cost of a higher-efficiency system is at its lowest relative to the long-term return. AIRONE provides a written efficiency payback calculation for every replacement quote showing the annual savings at each efficiency tier and the number of years to payback.

Should I replace my AC and furnace at the same time in Los Angeles?

Yes - if the furnace is within 3–5 years of the same age as the AC system, replacing both simultaneously reduces total labor cost by 15–25% compared to two separate replacements - because installation labor, permit, and inspection costs are shared across both systems rather than paid twice. According to ACCA installation cost benchmarks, combined HVAC replacements consistently deliver this cost advantage over staged replacements. AIRONE assesses both systems during the replacement visit and provides a combined vs separate cost comparison if the furnace is approaching end of life. A heat pump replacement eliminates this decision entirely - replacing both AC and furnace with a single unit that also qualifies for the federal $2,000 IRA tax credit.

Ask about combined AC + furnace replacement - Call (323) 471-1037 →

Does AIRONE perform a Manual J load calculation for AC replacement?

Yes - every AIRONE replacement begins with a Manual J load calculation using ACCA-approved software and actual home measurements. We do not replace like-for-like without verifying the previous system was correctly sized. According to ACCA, up to 50% of residential HVAC systems in the United States are incorrectly sized - the majority being oversized. An oversized replacement system short cycles, prevents adequate humidity removal, causes temperature swings, and accelerates compressor wear. Correct sizing at replacement time costs nothing extra and prevents this failure mode for the life of the new system.

Section 8 - R-22 Replacement

Replacing an R-22 System in Los Angeles - What You Need to Know

R-22 refrigerant replacement affects a significant portion of Los Angeles County homes - particularly those with systems installed between 2000 and 2010. If your system uses R-22, replacement planning should begin now - not after the next refrigerant leak.

Why does an R-22 AC system require replacement planning?

R-22 systems require immediate replacement planning because R-22 production was permanently stopped in 2020 - remaining supplies are being depleted and refrigerant service costs are rising sharply as availability decreases. The EPA phased out R-22 production and import under Section 605(a) of the Clean Air Act. Unlike earlier phase-down periods, this was a complete production stop - R-22 is no longer manufactured in the United States. A Southern California AC system that uses R-22 and develops a refrigerant leak in 2026 faces a dramatically different repair economics equation than the same leak in 2015 - and that equation will continue to worsen every year as remaining supplies decline.

Can an R-22 system be converted to R-410A or R-454B?

No. R-22 systems cannot be converted to R-410A or R-454B. These refrigerants operate at significantly higher pressures than R-22 - pressures that R-22 system components were not designed or certified to handle. Attempting to run R-410A in an R-22 system risks compressor failure, coil rupture, and refrigerant release. The only correct solution for an R-22 system that needs refrigerant service is full system replacement with equipment designed for current refrigerants.

How do I know if my AC system uses R-22?

The refrigerant type is printed on the system's nameplate - located on the outdoor condenser unit. R-22 systems show "R-22" or "HCFC-22" on the nameplate. Systems manufactured after approximately 2010 are more likely to use R-410A. If the system was installed before 2010 and you are unsure of the refrigerant type, call (323) 471-1037 - AIRONE identifies the refrigerant type during a free assessment visit.

What does R-22 AC replacement cost in Los Angeles?

The cost to replace an R-22 system with a modern R-410A or R-454B system follows the same replacement cost ranges as any standard replacement - $4,000–$7,000 for a standard central split system depending on size, brand, and efficiency tier. There is no R-22 surcharge on the replacement itself. The financial urgency of R-22 replacement comes from avoiding escalating refrigerant service costs - not from any price premium on the replacement system.

Section 9 - Efficiency & Rebates

What SEER2 Rating Should I Choose for My AC Replacement in Los Angeles?

For most Southern California homeowners replacing an AC system, a 16–18 SEER2 mid-efficiency system provides the best balance of upfront replacement cost and long-term energy savings - typically paying back the upgrade premium over minimum efficiency in 3–5 years in SoCal's 7–9 month cooling season, according to NOAA historical temperature data for the Los Angeles basin. Here is how to choose the right tier for your specific situation.

Is minimum efficiency (14–15 SEER2) right for my replacement?

This is the current federal minimum efficiency standard for California - lowest upfront replacement cost, highest long-term operating cost.

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

Is mid efficiency (16–18 SEER2) right for my replacement?

The best value replacement tier for most Southern California homeowners. The upgrade premium over minimum efficiency is typically $500–$1,500 at replacement time - and pays back in 3–5 years through lower SCE or LADWP bills in SoCal's long cooling season. In SoCal's 7–9 month cooling season, upgrading from a 14 SEER system to a 17 SEER2 system can reduce cooling energy consumption by 17–20%, measurable in your SCE or LADWP bill each month.

This tier is right for your replacement if: you plan to stay in the home 5+ years, you want SCE or LADWP rebate eligibility, or you want meaningful energy savings without the premium cost of variable-speed equipment.

Is high efficiency (19–22 SEER2) right for my replacement?

Variable-speed systems that modulate output based on real-time demand - running at lower capacity most of the time and ramping up only during peak heat. Superior humidity control, quieter operation, and more precise temperature maintenance than single-stage systems - particularly relevant for coastal South Bay and Orange County homes where humidity is a factor.

This tier is right for your replacement if: you plan to stay in the home 7+ years, comfort and humidity control are priorities alongside energy savings, or your previous system had trouble maintaining consistent temperature.

Is premium efficiency (23+ SEER2) right for my replacement?

The highest-efficiency residential replacement systems available - Carrier Infinity 26, Lennox XC25, and comparable units. Highest upfront replacement cost, lowest long-term operating cost, maximum rebate tier eligibility.

This tier is right for your replacement if: you have a long planning horizon, high electricity usage, and want maximum long-term return on the replacement investment.

Our 17-year-old Carrier finally gave out in August. Called AIRONE on a Monday, had a free quote the same day, and the new system was installed and running by Wednesday. Permit was handled, inspection passed first time, and the technician explained everything about the new system before leaving. Exactly what you need when your AC dies in an LA summer.

AIRONE was the only contractor who told me my 14-year-old system was actually worth assessing before replacing - until they identified the R-22 refrigerant issue. Once they explained the EPA phase-out and the cost trajectory of R-22 service, replacement was the obvious call. They quoted three replacement options in writing and let me choose. No pressure, no upsell.

Got three quotes for replacement. Two contractors gave me the same tonnage as my old system without any calculation. AIRONE did an actual load calculation, told me my old system was oversized, and recommended a smaller unit that costs less and runs more efficiently. Six months later my Edison bill is down and the house is more comfortable. The honest sizing sold me.

Used financing for the replacement - 0% APR made it easy to say yes even after an unexpected system failure. AIRONE handled everything: permit, haul-away of the old unit, installation, inspection. Never had to call the building department once. System is running perfectly.

AC Replacement Los Angeles - Frequently Asked Questions

AC replacement in Los Angeles typically costs $4,000–$7,000 for a standard central split system like-for-like replacement in a home with existing ductwork, $6,000–$10,000 for a high-efficiency upgrade, and $9,000–$14,000 for a premium variable-speed system. Package unit replacements typically cost $4,500–$7,500. Heat pump whole-home replacements typically cost $5,500–$12,000. All prices include permit, haul-away of the old system, labor, and commissioning. AIRONE provides a free written quote before any commitment. Call (323) 471-1037.
Replace your AC 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, the system uses R-22 refrigerant and has a refrigerant leak, or the $5,000 rule - system age multiplied by repair cost - exceeds $5,000. In Southern California's 7–9 month cooling season, systems degrade faster than in cooler climates, making these thresholds more financially compelling than in other US markets.
It depends on four variables: system age, repair cost as a percentage of replacement cost, refrigerant type, and repair history. Systems under 8 years old with single-component failures almost always make sense to repair. Systems over 12 years old with major component failures almost always make sense to replace. The 50% rule - referenced by Consumer Reports - is the most reliable single financial threshold: if repair costs more than half a new system, replace. AIRONE provides a written repair vs replace assessment after every diagnostic on aging systems.
A standard central AC replacement in a home with existing ductwork typically takes one full day - 6–8 hours for a two-technician AIRONE crew. Replacements requiring ductwork repair or electrical panel upgrades may take one to two days. Mini-split single-zone replacements typically take 4–6 hours. AIRONE provides a specific time estimate when scheduling the replacement.
Yes. Under California Building Code, a permit is required for AC replacement 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. AIRONE includes permit filing, permit fees, and inspection coordination in every replacement quote - you do not manage any part of the permit process.
For most Southern California homeowners, a 16–18 SEER2 replacement system provides the best balance of upfront cost and long-term energy savings - paying back the efficiency premium over minimum efficiency in 3–5 years in SoCal's 7–9 month cooling season. Homeowners planning to stay 7+ years should consider 19–22 SEER2 variable-speed systems. Homeowners selling within 5 years may find minimum efficiency (14–15 SEER2) most economical. AIRONE provides a written efficiency payback calculation with every replacement quote.
Yes. Southern California homeowners may qualify for SCE rebates up to $1,000 for qualifying high-efficiency replacement systems, LADWP rebates for qualifying systems, and SoCalGas rebates when replacing a gas-electric combination. Homeowners replacing with a heat pump may qualify for the federal $2,000 IRS Form 5695 tax credit under the Inflation Reduction Act. AIRONE identifies all applicable rebates during the replacement quote and provides documentation to support applications.
In most cases, no. Mismatched indoor and outdoor units from different efficiency generations operate at different refrigerant pressures and airflow specifications - reducing system efficiency and potentially voiding manufacturer warranties. If the indoor air handler or coil is in good condition and is the correct match for the new outdoor unit's specifications, AIRONE will confirm compatibility during the free assessment and quote accordingly. Mismatched replacement is one of the most common AC replacement errors in the Los Angeles market.
Yes - if the furnace is within 3–5 years of the same age as the AC system. Replacing both simultaneously reduces total labor cost by 15–25% compared to two separate replacements because installation labor, permit, and inspection costs are shared rather than paid twice - according to ACCA installation cost benchmarks. AIRONE provides a combined vs separate cost comparison during the replacement visit if the furnace is approaching end of life. A heat pump replacement eliminates this decision entirely - replacing both with a single unit.
AIRONE replaces old systems with all major brands including Carrier (10-year parts warranty, register within 60 days), Trane (among the strongest factory warranties, register within 60 days), Lennox (XC25 up to 26 SEER2), Rheem (10-year parts warranty, register within 90 days), and Goodman (lifetime compressor warranty when installed by licensed contractor, register within 60 days). Additional brands include Daikin, York, Mitsubishi, Fujitsu, American Standard, Bryant, and Amana. Call (323) 471-1037 if you have a brand preference.
Every AIRONE replacement quote includes new equipment, refrigerant line set, electrical connections, condensate drain, permit filing and fees, haul-away and disposal of the old system, installation labor, commissioning and testing, and post-install building inspection coordination. No line items appear on your invoice that were not on the signed quote.
Yes - haul-away and disposal of the existing system is included in every AIRONE replacement quote. Old refrigerant is recovered and disposed of in compliance with EPA Section 608 regulations. You do not arrange separate disposal - it is handled as part of the replacement at no additional charge.
Yes - and if your system uses R-22, replacement should be planned proactively rather than reactively. R-22 was permanently removed from US production in 2020 under Section 605(a) of the Clean Air Act. An R-22 system that develops a refrigerant leak faces significantly higher service costs than an R-410A system - and those costs will continue to increase as remaining supplies are depleted. AIRONE replaces R-22 systems with modern R-410A or R-454B systems at standard replacement cost ranges. Call (323) 471-1037 for a free R-22 replacement assessment.
Yes. A modern, high-efficiency AC system with a valid permit and inspection record removes a common home inspection contingency trigger and reduces buyer negotiation leverage on HVAC condition in LA County transactions. An aging system - particularly an R-22 system or one without maintenance records - typically results in price reductions or repair credits during sale negotiations that exceed the cost of proactive replacement.
Yes - AIRONE offers financing for all AC replacements including 0% APR options for qualifying customers and monthly payments starting under $100/month on qualifying systems. Financing is available for most customers and is particularly relevant for homeowners facing unexpected system failure. Subject to credit approval. Call (323) 471-1037 for current financing terms.
A new central AC replacement system in Los Angeles typically lasts 12–17 years with annual maintenance. Systems without maintenance may fail at 8–10 years. Heat pump replacement systems last 15–20 years with proper maintenance. Variable-speed systems - whether central or mini-split - typically last toward the longer end of these ranges because their compressors run at lower capacity most of the time, experiencing less mechanical wear than single-speed compressors that cycle fully on and off. AIRONE recommends enrolling in an annual maintenance plan on replacement day to protect the new system from day one.
The correct replacement size is determined by a Manual J load calculation - not by matching the size of the system being replaced. According to ACCA, up to 50% of residential HVAC systems are incorrectly sized - the majority being oversized. AIRONE performs Manual J on every replacement using ACCA-approved software and actual home measurements. As a general orientation: most 1,000–1,500 sq ft LA County homes require a 2–2.5 ton system, most 1,500–2,500 sq ft homes require 2.5–3.5 tons, and most 2,500–3,500 sq ft homes require 3.5–5 tons. Call (323) 471-1037 to schedule a free sizing assessment.
Yes - in two ways. First, replacing an aging AC system - particularly an R-22 system or an unpermitted installation - with a modern, permitted system can reduce the risk of insurance claim denial related to HVAC failures. Some California insurers rate homes with aging mechanical systems as higher risk. Second, an unpermitted AC installation can create grounds for claim denial if the installation is found to be a contributing cause of fire or property damage. AIRONE's permitted, inspected replacements provide documentation that the system meets California Building Code - documentation that supports your insurance coverage and satisfies disclosure requirements in a property sale.
The complete AC replacement process with AIRONE typically takes 5–15 business days from your first call to a fully installed and inspected system. Here is the typical timeline: free assessment visit (same week as your call in most cases), written quote delivered same visit, permit filing submitted within 1–2 business days of your approval, permit processing by the city or county (3–10 business days - some cities offer same-day over-the-counter approval for like-for-like replacements), installation day (1 full day for most standard replacements), and post-install building inspection (scheduled after installation, typically within 1–5 business days). In urgent situations - where a failed system makes the home uninhabitable - AIRONE prioritizes both scheduling and permit processing options to compress this timeline. Call (323) 471-1037 to discuss timeline options for your specific situation.
