When the heat goes out in Roanoke, VA, the clock starts ticking, and the diagnosis depends entirely on what kind of system is doing the failing. On a gas furnace, the most common no-heat call we run is a flame sensor coated in oxide: the burners light, the sensor cannot prove the flame, and the board shuts the gas down three tries later and locks out. Close behind come cracked hot surface igniters, stuck pressure switches, clogged condensate traps on high-efficiency models, and blower motors that have quietly worn out. Heat pumps fail differently: a weak defrost cycle leaves the outdoor coil buried under frost, a failed reversing valve strands the system in cooling, and a dead outdoor unit leaves the electric backup strips carrying the whole house at several times the operating cost.
Most of our service calls are for Furnace Repair. Start there if your system isn't running right.
When to Call for Heating Repair in Roanoke
Catching these issues early helps you avoid costly problems. Keep an eye out for the following clues:
- An outdoor heat pump coil that stays iced over
- Some rooms warm while others stay stubbornly cold
- The thermostat calls for heat but the vents blow cold air or nothing
- Strange smells from the vents, especially rotten egg or burning
- The furnace clicking and trying to light but shutting back down
- Higher heating bills with less comfort to show for them
- Booming or banging at ignition, a sign of delayed burner light-off
- Frequent on-off cycles that never bring rooms up to temperature
Early Action Saves Money
Most HVAC failures start small, a weak capacitor, a squealing blower, a system that runs a little longer each week. If you notice any of these signs, call (540) 646-1484 for a prompt inspection.
