Los Angeles Weather and HVAC Load
NOAA's 1991-2020 climate normals put Los Angeles at 1,240 heating degree days and 795 cooling degree days per year. Neither season dominates in Los Angeles. That balance is a big reason heat pumps and dual-fuel systems sell well in California. Freezing nights are rare here, but a normal year brings 6 days over 90°F. On the cooling side, a 2,000 sq ft house here usually needs around 2.5 tons. A tight, well-insulated house may get by with half a ton less.
| Heating degree days / year | 1,240 |
|---|---|
| Cooling degree days / year | 795 |
| Nights at or below 32°F | 1 |
| Days above 90°F | 6 |
| Average low / high | 55.3°F / 72.2°F |
Los Angeles Housing Stock
Census figures put the median build year in Los Angeles at 1964, so a typical house here has about 62 years on it. A lot of these homes are on their second or third system by now. The ductwork is usually original, and leaky joints are common. Los Angeles has roughly 515,000 owner-occupied homes, or 36.3% of households. Homes here have a median value of $879,500 and households a median income of $80,366. Those two numbers drive the labor adjustment in our estimate.
NOAA storm reports for Los Angeles County show 3 hail days and 10 days with damaging thunderstorm winds over the six years from 2020 to 2025. The largest hail reported was 1 inches across. Storms here are more likely to cause power surges than coil damage, so a surge protector on the outdoor unit is worth the small cost. Los Angeles County also had 5 tornado days in that period.
When It Makes Sense
- It still runs on R-22 refrigerant
- The house can't reach the thermostat setting on hot afternoons
- The AC is 12 to 15 years old or more
- It has had more than one refrigerant leak
What Moves the Price
- Electrical work such as a new disconnect, breaker or wiring
- The pad, permit and refrigerant (R-410A or the newer R-454B)
- Whether the coil and line set also need replacing
- SEER2 rating and whether the compressor is single-stage or variable-speed
- Tonnage, based on house size and local climate
For Los Angeles we raised the national figures about 22%, based on local income, home values and climate-based equipment sizing. Get at least three written quotes; real bids can land outside this range.
What the Quote Should Cover
- The electrical disconnect and wiring
- Startup, an airflow check and warranty registration
- Removing the old condenser and coil
- The new condenser, coil and, if needed, line set
- Refrigerant charge and a leak test
California Permits, Efficiency Rules and Rebates
California is in the DOE's Southwest region, where new split central air conditioners need at least 14.3 SEER2 (13.8 SEER2 for systems of 45,000 BTU/h and up). The Southwest also sets a minimum EER2, which measures efficiency at peak heat. Expect the contractor to pull a mechanical permit for a replacement job in Los Angeles. If a bidder suggests skipping it, move on. Also ask for a California license or registration number and proof of insurance. The federal 25C tax credit ended for equipment installed after December 31, 2025, so incentives now come mostly from utilities and state programs. Check your electric and gas utility's rebate page before you pick equipment.
Before You Hire
- Buy the condenser and coil as a matched set, or you may void the manufacturer warranty.
- Ask what federal, state or utility incentives apply to the model you're quoted.
- Fall and early spring installs often come with better pricing and shorter waits.

AC Installation Questions from Los Angeles Homeowners
How much is new AC installation in Los Angeles?
Plan on $5,100 to $11,500, with most jobs near $8,600. Equipment efficiency, house size and the condition of the ducts and wiring decide where your quote falls.
When is the best time to schedule new AC installation in Los Angeles?
In spring or fall. Those are the slow months between heating and cooling season in Los Angeles.
What size AC do I need?

How long does a new AC last?
With yearly maintenance, 12 to 17 years. Salt air and extreme heat shorten that.
