San Bernardino customers on our thermostat service

★★★★★

Called three companies for a no-cool emergency in San Bernardino. These were the only ones who gave a real arrival time and actually kept it.

Angela D., San Bernardino
★★★★★

They sealed and repaired our attic ducts and the back bedrooms are finally the same temperature as the rest of the house. Should have done this years ago.

Rachel S., San Bernardino

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