Below is what to know before you repair or replace a system here, from permits to the license your contractor should hold.
Antelope Valley homes need both cooling and heating. NOAA's 1991 to 2020 averages show about 36 days a year at 100°F or hotter in Lancaster and Palmdale, and 50 to 70 nights at or below freezing. Every Antelope Valley ZIP code is in California Energy Code climate zone 14, which decides what has to be tested when equipment is replaced.
In California, HVAC contractors are licensed by the Contractors State License Board (CSLB) under the C-20 classification, the only license class for heat pump heating and cooling. Replacing a central air conditioner, heat pump or furnace needs a building permit from your city or county. Under the 2025 Energy Code, in effect since January 1, 2026, a replacement also means the ducts must be sealed and tested in most cases, with the result checked by an independent rater, and in climate zone 14 the refrigerant charge and airflow of a new air conditioner must be verified too. Ask your contractor to pull the permit: it protects you, and some rebates require it.
New central air conditioners and heat pumps use lower-impact refrigerants under federal and California rules that took effect in 2025, though equipment made before 2025 can still be installed. Rebates change often. TECH Clean California's heat pump incentives are fully reserved, and the federal tax credit for heat pumps and furnaces ended for equipment installed after 2025. SoCalGas offers a 2026 rebate on high-efficiency furnaces installed by a licensed contractor, and SCE's Energy Savings Assistance program can replace an eligible central air conditioner or heat pump at no cost for income-qualified households while funds last. Check each program's current terms before you buy.

Frequently asked questions
- Do I need a permit to replace my air conditioner in Lancaster or Palmdale?
- Yes. California requires a building permit to install any heating or cooling system other than a plug-in room unit, and that includes like-for-like replacements. Lancaster and Palmdale issue permits through their building and safety departments, Los Angeles County handles Quartz Hill, and Kern County handles Rosamond. A licensed contractor normally pulls the permit as part of the job.
- What license should an HVAC contractor have in California?
- A C-20 (Warm-Air Heating, Ventilating and Air-Conditioning) license from the Contractors State License Board. You can check any license number on the CSLB website. Since 2025, unlicensed work is allowed only on jobs under $1,000 that need no permit, so an air conditioner or furnace replacement always calls for a licensed contractor.
- Why does my contractor need to test the ducts?
- Under California's 2025 Energy Code, replacing a furnace, air handler, outdoor air conditioner or heat pump unit, or coil means the ducts must be sealed and tested, with the result verified by an independent rater. Leaky ducts in a hot attic waste cooling you pay for. Systems with less than 40 feet of duct, ducts containing asbestos and ducts already certified are exempt.
- Are there rebates for a new heat pump or furnace in the Antelope Valley?
- Some, but they change often. TECH Clean California's heat pump incentives are fully reserved, and the federal tax credit ended for equipment installed after 2025. As of late 2026, SoCalGas offers a rebate on ENERGY STAR furnaces of 92% efficiency or better installed in 2026, and SCE's Energy Savings Assistance program helps income-qualified households. Check with SCE and SoCalGas for current terms.
- Can my existing air conditioner still be serviced with R-410A?
- Yes. The 2025 refrigerant rules apply to new equipment, and units made before 2025 can still be installed. California will stop sales of newly produced R-410A in 2030, but reclaimed refrigerant can still be sold after that, so existing systems can keep being serviced.
