Monrovia 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., Monrovia

Replaced our 20-year-old furnace and AC with a heat pump. Clean install, explained everything, and our summer bill dropped noticeably. Great thermostat service experience.

Anthony P., Monrovia
★★★★★

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