Furnace Blowing Cold Air? Get Help Fast
When your furnace runs but blows cold air, the system is not completing the heating cycle. This frustrating situation means your furnace is consuming energy without warming your home.
What Causes Cold Air from a Furnace
Common causes include a faulty gas valve that is not opening, a failed ignitor that lights but does not stay lit, a blocked condensate line causing a safety shutdown, a dirty flame sensor, or a malfunctioning control board.
System Safety Lockout
Most modern furnaces will enter a safety lockout mode after several failed ignition attempts. This is a protection feature. Do not repeatedly reset the system. Our technician will diagnose why the furnace is failing to heat and restore proper operation.

Safety Reminder
If you smell gas, suspect carbon monoxide or believe there is an immediate danger, leave the property and contact emergency services or the appropriate gas emergency authority. Do not remain inside — exit the building immediately and call for help from outside.
