Before You Call
Check that the thermostat is set to heat and the setpoint is above room temperature, the furnace switch (it looks like a light switch) is on, and the filter isn't clogged. If you're on propane, check the tank level. If those are fine, it's time for a technician.
If you smell gas
Leave the house, don't flip switches, and call Puget Sound Energy or your propane supplier and 911 from outside. Don't restart the furnace until it's been checked.
What Changes the Price of a Furnace Repair
Every furnace repair job is quoted after a technician sees the equipment and the house. What moves the price: the age and brand of the system, access (crawl space, attic, garage or closet), parts availability, whether a permit is needed, and whether it's an after-hours call.

Furnace Repair Questions
Why does my furnace keep shutting off?
A dirty flame sensor, a clogged filter, an overheating heat exchanger or a failing control board are common causes. Each needs a different fix, so it gets tested first.
Is it worth repairing an old furnace?
It depends on the age, the repair and the condition of the heat exchanger. Once a furnace is past 15 to 20 years and needs a major part, replacement or a heat pump is often worth pricing.
Do you work on propane furnaces?
Yes. Many homes around Cottage Lake and Duvall run on propane, and we service those furnaces too.
