San Diego Housing Stock
The median San Diego home dates to 1978, according to the Census ACS. That makes the typical house about 48 years old. A lot of these homes are on their second or third system by now. The ductwork is usually original, and leaky joints are common. San Diego has roughly 249,000 owner-occupied homes, or 47.6% of households. Homes here have a median value of $848,500 and households a median income of $104,321. Those two numbers drive the labor adjustment in our estimate.
Between 2020 and 2025, NOAA's Storm Events Database logged 6 hail days and 18 days with damaging thunderstorm winds in San Diego County. 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.
When It Makes Sense
- The house heats with electric baseboard, oil or propane
- Your AC needs replacing, and you'd like cheaper heat at the same time
- There's no natural gas service on your street
What Moves the Price
- Electrical panel capacity and wiring
- Backup heat, either electric strips or a gas furnace (dual-fuel)
- Size in tons, and whether the unit is cold-climate rated
- A ducted system or a ductless mini-split
- Variable-speed (inverter) or single-stage compressor
For San Diego we raised the national figures about 31%, 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
- A load calculation and equipment selection

- Thermostat setup and backup heat settings
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 San Diego; 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
- Where winters get cold, ask for a model on the NEEP cold-climate list.
- Make sure the installer sized the system for your heating load, not only cooling.
- Ask your electric utility and state energy office what heat pump rebates are open right now.

Heat Pump Installation Questions from San Diego Homeowners
How much is heat pump installation in San Diego?
Plan on $7,200 to $17,600, with most jobs near $12,900. Equipment efficiency, house size and the condition of the ducts and wiring decide where your quote falls.
When is the best time to schedule heat pump installation in San Diego?
In spring or fall. Those are the slow months between heating and cooling season in San Diego.
How long does a heat pump last?
Usually 12 to 15 years. A heat pump runs year-round, so it needs maintenance twice a year rather than once.
Do heat pumps work in cold weather?
Yes. Cold-climate heat pumps keep making heat well below 0°F. They lose efficiency as it gets colder, so many homes in cold regions keep backup heat.
