Serving Oakley
Oakley is about 3 miles southeast via Bridgehead Rd and Main St from our Antioch shop, and we serve all of it, including Summer Lake, Emerson Ranch and Cypress Grove. Most Oakley homes heat with PG&E gas furnaces and about a quarter use electric heat, so we service both and talk through heat pump options when an older furnace wears out. On every furnace repair in Oakley, 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 Oakley?
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.
