Rancho Santa Margarita customers on our thermostat service

★★★★★

Had them out for an AC tune-up before summer. Thorough inspection, cleaned the coils, and they found a weak capacitor that would have failed in July. Smart move.

James W., Rancho Santa Margarita
★★★★★

Furnace kept shutting off every few minutes. They found a dirty flame sensor and a clogged filter, cleaned both, and it has run perfectly since. Quick and affordable thermostat service.

Carlos V., Rancho Santa Margarita
★★★★★

Our AC quit during the hottest week of the year and they had a technician at our Rancho Santa Margarita home the same afternoon. Fixed a capacitor, charged exactly what was quoted. Cold air within an hour.
