Serving Byron
We serve every part of Byron, including Byron Hwy corridor, Camino Diablo, Byron Airport and Clifton Court Forebay - it's about 15 miles southeast via SR 4 and Byron Hwy from our Antioch shop. Only about a third of Byron homes use utility gas, and the rest mostly heat with propane or electricity, so we service propane furnaces and help with heat pump conversions. On every furnace repair in Byron, 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 Byron?
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.
