Overview
What we do with air conditioning in San Diego homes
Most of our residential work is one of three things. We replace whole systems: condenser, coil and furnace or air handler, sized from a load calculation, permitted when the job needs it, and tested. We repair systems that have stopped cooling, from a failed capacitor to a refrigerant leak, with the price written before the work starts. And we maintain systems so the common August failures get caught in April.
San Diego is not one climate. Coastal Zone 7 homes in Point Loma, Carlsbad and University City cool for a few weeks a year and live with the marine layer; inland Zone 10 homes in Escondido, Poway, Santee and El Cajon run air conditioning hard from June through October. The right equipment, efficiency tier and duct work differ between the two, and so does the case for a heat pump. Our estimates start with where the house is and how it is built: a 1970s tract home with attic ducts needs a different conversation than a 2005 two-story in Carmel Valley with two systems.
Every job we do is under CSLB license #669421 (C-20 HVAC and C-10 electrical), permitted where the code requires it, and quoted in writing with model numbers.

Repair or replace? How to decide
The question we are asked most. Age, the failed part and refrigerant type settle it more often than anything else. When two or more signals point right, we quote both so you can compare actual numbers.

What San Diego homeowners say

“Superior Air installed a new air conditioning system at our home in San Diego, and the entire process was smooth and efficient. The team arrived on time and were able to complete the job in just a few hours. They also made sure to cover and protect our floors while they worked. Now the new AC unit runs perfectly and the house cools down much faster than before.”
“Chris was great. He replaced our old split system and the house is cooling much faster now. Mike on the phone was also very responsive and was able to get me a quote within an hour and took the time to explain available rebates and different replacement options.”
“Superior Air came out to inspect our split HVAC system after another company told us we needed a full replacement. Their technician was able to diagnose the issue and repair the system in a few hours for a fraction of the cost. Very honest company and great customer service.”
