Do this now: AC not cooling in San Diego
- Check the basics: thermostat on Cool and set below room temperature, the breaker for the outdoor unit, and the filter. DOE says to clean or replace the filter every month or two in cooling season.
- Ice on the lines or coil? Bryant says to switch the thermostat from Cool to Off, let it thaw for several hours, do not chip the ice, and change the filter while you wait.
- Water dripping from the indoor unit? Turn the AC off; ENERGY STAR says a plugged condensate drain can cause water damage.
- Hot inside during a heat warning? Go to a County Cool Zone (1-800-339-4661, weekdays) and call 911 for heat stroke signs.
- Call the heating and AC line with the system's age and what it is doing.
AC repair in San Diego is fixing a central air conditioner or heat pump's capacitor, contactor, fan motor, refrigerant leak, coil or drain. ConsumerAffairs puts San Diego repairs at $150 to $2,500 (April 2026).
Is it an emergency? No AC in a San Diego heat warning
No AC is an emergency in San Diego when the County posts a Heat Warning and someone at higher risk is home. The County posted one for the coasts and valleys from October 2 to October 8, 2026, with the deserts under a warning from October 7 to 9. The CDC names people 65 and older, infants and young children, and people with asthma or heart disease among those at higher risk from heat.
- Call today: a heat warning with a vulnerable person at home, water from the air handler soaking a ceiling, or a breaker that trips again after one reset.
- Can wait for regular hours: a system that sat unused and will not start on a mild day. Emergency labor runs $160 to $250 an hour nationally, HomeGuide says, against a $100 to $250 diagnostic fee in San Diego.
Why San Diego ACs fail on the first hot day
Most San Diego air conditioners sit idle for months. Lindbergh Field averages just 3.0 days a year at or above 90 F and 0.1 days at or above 100 F, NOAA's 1991 to 2020 normals show, so a weak capacitor or a clogged drain often shows up on the first hot day of fall. HomeAdvisor puts a yearly tune-up at $80 to $100, cheaper than most of the repairs above. Test the AC in late summer, before the heat waves the County tends to post in fall. Inland valleys run hotter than the airport, which is why the County issues separate warnings for coasts, valleys and deserts. National causes are on AC not cooling.
Old refrigerant: repair or replace
U.S. production and import of R-22, the refrigerant in many older systems, ended on January 1, 2020, EPA says; existing systems can keep using it, but recharges cost more, $180 to $600 at HomeGuide's figures against $100 to $320 for R-410A. HomeGuide and HomeAdvisor both suggest replacing an AC that is over 10 years old, uses R-22, or needs a repair costing half the price of a new unit. In San Diego a full system replacement runs $7,000 to $18,000, ConsumerAffairs says; see AC installation in San Diego.
San Diego help with cooling costs
SDG&E's Energy Savings Assistance program lists room AC replacement and portable AC among its no-cost upgrades for qualifying customers, though central AC is not on the list. The one-person income limit is $39,900 from June 1, 2026 to May 31, 2027. For a place to cool off while the AC is down, County Cool Zones are free, air-conditioned public sites.
