Tierrasanta sits surrounded by Mission Trails Regional Park on three sides, equipment placement for fire-zone clearance and ember-resistant air-intake screening are now standard considerations on every replacement. Original 1970s-80s forced-air systems are replacing in waves driven by both age and inland-valley cooling load.. We account for local conditions in every job.
