How to choose an HVAC company in San Marcos

Ask for a load calculation before you replace a system, not just a size match.
Compare efficiency ratings (SEER2/AFUE) and available rebates.
Ask what maintenance plans cost and what they cover.

Check the license: Contractors State License Board (CSLB). In California, most home improvement work above the state's small-job limit requires a CSLB license. Look the number up before you sign, and check that it is active and bonded.
