HVAC Services in San Marcos, CA
Our headquarters city, served from 130 Bosstick Boulevard since the company’s early days.
San Marcos is home ground. Action Air Conditioning & Heating is headquartered at 130 Bosstick Boulevard #101, and the city around it holds every kind of work we do: newer developments in San Elijo Hills and the city’s growth corridors, established neighborhoods with mid-life systems, student rentals near Cal State San Marcos, and a steady wave of ADUs and garage conversions that need conditioning of their own.
We have served this community since 1975, and we look forward to helping you if you’re ready to give us a call.

Frequently Asked Questions
FAQs
Where is Action Air located?
Yes. Our headquarters is at 130 Bosstick Boulevard #101, San Marcos, CA 92069, and the city has been our home base while we have served San Diego and Riverside counties since 1975.
Do you handle HVAC for San Marcos ADUs and garage conversions?
Yes, and ductless equipment usually fits them best: independent control, no duct extension from the main house, and sizing matched to the small space. The estimate compares options for your specific unit.
Can you service rental properties near Cal State San Marcos?
Yes. We work with owners and property managers on access and approvals, and tenant no-cool and no-heat situations are treated with the urgency habitability deserves.
Does being in Action Air’s home city change anything about scheduling?
Our office and dispatch are here, and San Marcos sits at the center of our service area rather than its edge. Same-day estimates for system replacement apply here as everywhere we serve.
Which communities near San Marcos does Action Air serve?
Escondido to the east, Vista to the west, Oceanside beyond it, and the rest of North County, plus Fallbrook, Temecula, and Murrieta to the north.
