Homes in San Marcos
San Marcos and neighboring Vista combine 1970s–80s ranch homes and mobile-home communities, the lake-side homes of Lake San Marcos, and large newer master-planned communities such as San Elijo Hills and Rancho Tesoro built after 2000. Cal State San Marcos and the Highway 78 corridor add multi-family and commercial buildings.
The newer communities are now entering their first replacement cycle, often with two systems per home and equipment on side yards close to neighbors. Older homes in central San Marcos and Vista frequently have package units on the roof or original furnaces with add-on cooling.

What San Diego homeowners say
Reviews left on Google by Superior Air customers. Names abbreviated for privacy.
“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.”
