All servicesQuestions 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 Summer Lake?
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.
