Serving Bethel Island
Bethel Island is about 10 miles east via East Cypress Rd and Bethel Island Rd from our Antioch shop, and we serve all of it, including Delta Coves, Bethel Island Rd, Gateway Rd and Taylor Rd. Bethel Island has almost no utility gas, so homes heat with electricity or propane, and we work on heat pumps, package units and propane furnaces rather than standard gas furnaces. On every furnace repair in Bethel Island, 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 Bethel Island?
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.
