Long Beach Weather and HVAC Load
NOAA's 1991-2020 climate normals put Long Beach at 1,173 heating degree days and 1,165 cooling degree days per year. Neither season dominates in Long Beach. 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 23 days over 90°F.
| Heating degree days / year | 1,173 |
|---|---|
| Cooling degree days / year | 1,165 |

Long Beach Housing Stock
Census figures put the median build year in Long Beach at 1958, so a typical house here has about 68 years on it. Houses that old often still have duct runs sized for an old coal or oil furnace and 60- or 100-amp electrical panels. Both can add cost when new equipment goes in. Long Beach has roughly 70,000 owner-occupied homes, or 40.9% of households. Homes here have a median value of $762,200 and households a median income of $83,969. Those two numbers drive the labor adjustment in our estimate.
Los Angeles County had 3 hail days and 10 days with damaging thunderstorm winds from 2020 through 2025, according to NOAA storm records. 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.

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. Plan on a mechanical permit for most replacements in Long Beach; the contractor normally pulls it. Before you sign, ask each bidder for their 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
- Ask for a duct leakage test. Leaky ducts can lose 20 to 30% of what the system puts out.
- Get one quote for a heat pump system and one for a furnace plus AC.
- Make every bidder quote the same efficiency ratings, or the prices won't compare.
