In a normal year, Irvine racks up 1,286 heating and 1,246 cooling degree days (NOAA 1991-2020 normals). Neither season dominates in Irvine. That balance is a big reason heat pumps and dual-fuel systems sell well in California. A normal year brings 2 nights at or below freezing and 35 days over 90°F.
| Heating degree days / year | 1,286 |
|---|---|

Irvine Housing Stock
Half the homes in Irvine were built before 2001 (Census ACS median), so the typical house is about 25 years old. Plenty of houses from this period still run original 1990s or early-2000s equipment, which is past its expected service life. About 49,000 households here own their home, 43.8% of the occupied total. With a median household income of $129,647 and a median home value of $1,115,400, local labor rates come out above the national middle in our model.
Orange County had 2 days with damaging thunderstorm winds from 2020 through 2025, according to NOAA storm records. 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.

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. Equipment replacements in Irvine generally need a mechanical permit, and a reputable contractor will pull it for you. Ask for their California license or registration number and a certificate of insurance with the quote. 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 your gas or oil company about rebates on condensing boilers.
- Ask for a heat-loss calculation. A lot of old boilers are much bigger than the house needs.
- For a steam system, hire a contractor who works on steam regularly.
