Serving Pleasant Hill
Pleasant Hill is about 22 miles west via SR-4 and SR-242 from our Antioch shop, and we serve all of it, including Gregory Gardens, Poets Corner, Downtown Pleasant Hill and Reliez Valley. Pleasant Hill sees a few freezing nights most winters, and in the older Gregory Gardens ranches, a furnace replacement often makes the most sense alongside new ductwork. On every furnace repair in Pleasant Hill, 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 Pleasant Hill?
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.
