Emergency Furnace Repair in Centennial
Centennial winters can drop well below freezing overnight, so a furnace that will not run is more than an inconvenience. Common culprits are dirty flame sensors, failed igniters, clogged filters, worn inducer or blower motors and blocked exhaust or intake pipes. A licensed technician can test the system safely and tell you whether a repair is worth it on your unit.

Parts for older or less common models can be harder to find and cost more.

Diagnostic fee

Questions homeowners ask
Why is my furnace blowing cold air?
Common causes are a dirty flame sensor, a failed igniter, a clogged filter or a blocked condensate drain on high-efficiency units. A technician can pinpoint which one.
Should I keep resetting my furnace?
One reset is fine. If it keeps locking out, stop and have it checked, since repeated restarts can hide a venting or safety problem.
Can snow block my furnace vents?
Yes. High-efficiency furnaces often vent through PVC pipes on an outside wall, and drifting snow or ice can block them and shut the furnace down.
How do I keep pipes from freezing while I wait?
Open cabinet doors under sinks on outside walls, let faucets drip slightly and use safe space heaters with plenty of clearance.
