Serving East Contra Costa
Blue Star is based on Wilbur Avenue in Antioch, and East Contra Costa is our home turf, from Pittsburg and Bay Point to Oakley, Brentwood, Discovery Bay and the Delta towns. Most East County homes heat with gas furnaces, but in Bethel Island, Knightsen and Byron many rely on propane or electric heat, which makes heat pumps a natural upgrade. On every furnace repair in East Contra Costa, 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 East Contra Costa?
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.
