AIRONE performs a Manual J heat load calculation on every furnace installation - accounting for square footage, ceiling height, insulation, window area, and SoCal climate data. Oversized furnaces short-cycle, wear out faster, and waste gas. Undersized furnaces can't maintain setpoint on cold nights. AIRONE sizes for your home, not for the next size up on the price sheet.
Schedule a Free Assessment → (323) 471-1037Furnace installation in California requires a building permit and a gas permit under California Mechanical Code Section 106 and California Plumbing Code. AIRONE files both permits, pays the fees as part of your quoted price, schedules the inspection, and is present during inspection. You do not manage any part of the permit process.
Ask About Permit Timelines → (323) 471-1037AIRONE installs Carrier, Trane, Lennox, Rheem, Goodman, Daikin, Ruud, York, Bryant, American Standard, Amana, Heil, and others. Brand recommendation is based on your home's needs, efficiency goals, and budget - not which brand generates the highest installer margin.

Los Angeles homes primarily use gas furnaces - natural gas is the dominant heating fuel across LA County, South Bay, and Orange County. Here are the four main furnace configurations AIRONE installs.
A single-stage furnace runs at 100% capacity every time it fires. It is the lowest cost option upfront and adequate for mild SoCal winters when runtime is limited. The 80% AFUE minimum means 20 cents of every gas dollar is lost through combustion exhaust.
A two-stage furnace runs at 60–65% capacity most of the time and kicks to 100% only on the coldest nights. The result is fewer on/off cycles, more even heat distribution, and 10–15% lower gas consumption than a single-stage unit. This is the most common furnace choice for SoCal homeowners replacing an aging system.
A variable-speed furnace modulates its output continuously - from 40% up to 100% - matching real-time heat loss rather than cycling on/off. The result is more precise temperature control, dramatically quieter operation, and AFUE ratings up to 98% - meaning 98 cents of every gas dollar becomes heat. Eligible for SoCalGas rebates and IRS §25C federal tax credit (up to $600 annually under the Inflation Reduction Act).
A heat pump replaces both the furnace and the AC in one installation, using electricity and refrigerant to move heat rather than burning gas. In SoCal's mild winters, heat pumps operate at 250–350% efficiency (COP 2.5–3.5) - producing $2.50–$3.50 of heat for every $1.00 of electricity. Qualifies for the federal $2,000 IRS Form 5695 tax credit (IRA §25C) and TECH Clean California rebates up to $3,000 through SoCalGas and SCE.
| Factor | Single-Stage | Two-Stage | Variable-Speed | Heat Pump |
|---|---|---|---|---|
| Efficiency (AFUE/COP) | 80% | 80–96% | 95–98% | 250–350% COP |
| Firing stages | 1 | 2 | Variable | Continuous |
| Noise level | Louder | Moderate | Quietest | Quiet |
| Gas use vs single-stage | Baseline | –10–15% | –20–30% | No gas |
| Federal tax credit | No | No | Up to $600 | Up to $2,000 |
| Utility rebate eligible | No | Yes | Yes | Yes |
| Typical installed cost | $3,500–$5,500 | $4,500–$7,000 | $6,000–$9,500 | $5,500–$12,000 |
| Best for | Budget / short term | Most SoCal homes | Long-term owners | Replace AC + heat |

Every AIRONE furnace installation follows the same 7-step process from free assessment through permitted inspection.

Yes. Under California Mechanical Code Section 106, a mechanical permit is required for new furnace installation and furnace replacement in all California jurisdictions. A gas permit is additionally required under California Plumbing Code for any gas appliance connection or replacement. The permits trigger building inspections that verify the installation meets California Mechanical Code requirements, correct venting and flue configuration, proper gas pressure and connections, and carbon monoxide safety compliance.
California Mechanical Code (CMC) Title 4 governs the installation, alteration, and repair of heating, ventilating, and air-conditioning systems in California. CMC requirements for furnace installation include minimum clearance distances, flue and vent sizing, combustion air supply, gas connection specifications, and safety control requirements. A Title 24 energy compliance check is also required for new furnace installations - verifying that the equipment meets California's minimum AFUE efficiency standards for the climate zone. AIRONE handles all CMC and Title 24 compliance documentation as part of every installation.
An unpermitted furnace installation in California creates three specific risks. First, homeowner's insurance may deny claims related to a fire, gas leak, or CO event if an unpermitted installation is identified as a contributing cause. Second, unpermitted work creates disclosure obligations in a property sale and may require remediation before escrow closes. Third, some manufacturer warranties are void if the installation was not permitted and inspected. AIRONE includes permit filing and inspection coordination in every installation - this is not optional and is not an upsell.
Yes - AIRONE files the mechanical permit and gas permit with your city or county building department, pays the permit fees as part of the quoted installation price, schedules the building inspection, and is present during the inspection. You do not need to contact the building department, take time off for the inspection, or manage any part of the permit process. After the inspection passes, AIRONE provides all compliance documentation in writing.

AFUE - Annual Fuel Utilization Efficiency - measures what percentage of gas consumed is converted to usable heat. An 80% AFUE furnace loses 20 cents of every gas dollar through exhaust. A 98% AFUE furnace loses only 2 cents. Here is how to choose the right efficiency tier for a Southern California home.
Meets California minimum for replacement. No federal tax credit. No SoCalGas rebate on standard 80% units. Lowest equipment cost.
10–15% lower gas consumption than 80% AFUE. Most SoCalGas residential rebate programs require a minimum 95% AFUE for rebate eligibility. Check current rebate availability at socalgas.com/rebates. Two-stage units in the 80–96% range are the most common replacement choice in Los Angeles.
Qualifies for IRS Form 5695 §25C tax credit - up to $600 per year under the Inflation Reduction Act (2023–2032). Qualifies for SoCalGas high-efficiency rebates. Runs quieter and provides more consistent heat than lower efficiency units. Pays back the efficiency premium in 4–6 years for most LA homeowners.
Qualifies for $2,000 IRS Form 5695 §25C federal tax credit and TECH Clean California rebates up to $3,000 through SoCalGas and SCE. In SoCal's mild climate, heat pumps run at 250–350% COP most of the year - far exceeding any gas furnace efficiency. Best financial case when AC is also near end of life.

AIRONE installs furnaces throughout all of LA County with permit filing in every city's building department. San Fernando Valley cities (Burbank, Glendale, Pasadena, Alhambra, Arcadia) have the highest furnace replacement demand in the AIRONE service area - inland valley winter temperatures regularly reach the low 40s and below, driving more annual heating hours than coastal cities. AIRONE is familiar with permit requirements across all 126 cities in the service area.
South Bay furnace installation with same flat-rate pricing, permit filing, and inspection coordination. Coastal areas have milder winters but furnaces are still essential for cold overnight temperatures and heat wave recovery cycles. Salt air accelerates heat exchanger corrosion - AIRONE recommends stainless steel heat exchanger models for properties within 1 mile of the coast.
OC furnace installation with same permit compliance and flat-rate pricing. Inland OC cities - Anaheim, Yorba Linda, Irvine - have noticeably cooler winters than coastal OC and generate higher furnace replacement demand. AIRONE files permits with Orange County and all incorporated OC city building departments.
