Signal Hill customers on our thermostat service

★★★★★

Installed a ductless mini split in our garage conversion. Neat work, quiet unit, and they walked us through the remote and app. Very happy.

Patricia H., Signal Hill
★★★★★

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., Signal Hill
★★★★★

The technician was on time, wore shoe covers, showed me the failed part and explained the repair versus replace math. Fair price and no pressure.
