Maintenance in San Marcos, CA.
Maintenance for San Marcos homes, done by licensed San Diego County technicians. A proper tune-up is not a filter change and a handshake. Our 21-point maintenance visit measures static pressure, refrigerant subcooling and superheat, capacitor microfarads, amp draw, and temperature split across the coil.
