Serving Brentwood
Brentwood is about 8 miles southeast via Main St and Brentwood Blvd from our Antioch shop, and we serve all of it, including Summerset, Trilogy at the Vineyards, Shadow Lakes and Deer Ridge. Brentwood winter nights have dropped to 20°F, and most homes here heat with PG&E gas, so we service furnaces and help owners weigh a heat pump when it is time to upgrade. On every furnace repair in Brentwood, we check the burners, flame sensor, venting and heat exchanger before we call the job done.

Questions before you call
Why is my furnace blowing cold air?
Common causes are a thermostat set to 'fan on', a dirty flame sensor, a failed igniter, a clogged filter tripping the high-limit switch, or a heat pump stuck in defrost. We test each one and fix the actual cause.
How much does furnace repair cost in Brentwood?
Small fixes like a flame sensor or igniter cost far less than a blower motor or control board. We diagnose first and quote the repair before starting, and we'll tell you if replacement makes more sense.
What should I do if I smell gas near my furnace?
Leave the house, don't flip switches, and call PG&E (or your propane supplier) or 911 from outside. Once it's safe, call us to find and repair the cause.
