From the hallway, a furnace that will not heat looks the same no matter what broke. Inside the cabinet, though, everything happens in a strict order: inducer on, pressure switch closed, igniter glowing, gas valve open, burners lit, flame proven, and finally the blower moving heat through the ducts. Most of the diagnosis comes down to finding the broken link. In Lakewood homes, it tends to be the same handful of culprits: a flame sensor coated in oxide, a hot surface igniter cracked by thermal cycling, a pressure switch held open by a tired inducer or a plugged condensate trap, or a control board with a burned relay.

When to Call for Furnace Repair in Lakewood
Catching these issues early helps you avoid costly problems. These are the signals our technicians see most often:
- A fan that keeps running while the registers blow cool air
- A flame that burns soft and yellow rather than steady blue
- Short cycling every few minutes without reaching the setpoint
- Repeated shutdowns just seconds after the burners light
- Water, rust stains, or black soot around the flue or cabinet
- A bang or boom when the burners ignite late
- Squealing or grinding from the blower compartment
- The furnace clicks and glows but the burners never light
