From the hallway, a furnace that will not heat looks the same no matter what broke. Inside the cabinet, though, the sequence is strict: inducer on, pressure switch closed, igniter glowing, gas valve open, burners lit, flame proven, and finally the blower sending heat through the house. Most of the diagnosis comes down to finding the broken link. In Newport News 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 Newport News
Catching these issues early helps you avoid costly problems. These are the signals our technicians see most often:
- Repeated shutdowns just seconds after the burners light
- Squeals, scrapes, or grinding noises behind the blower door
- The furnace clicks and glows but the burners never light
- Water, rust stains, or black soot around the flue or cabinet
- A flame that burns soft and yellow rather than steady blue
- Short cycling every few minutes without reaching the setpoint
- A bang or boom when the burners ignite late
- Air moving through the vents that never gets warm
Don't Wait for a Total Failure
