No two heating systems break the same way, and in Collierville homes the first question on any no-heat call is what kind of equipment we are dealing with. Gas furnaces most often stall on an oxidized flame sensor. The burners fire, the sensor fails to confirm the flame, and after three attempts the control board closes the gas valve and locks the system out. Cracked hot surface igniters, sticking pressure switches, plugged condensate traps on high-efficiency units, and tired blower motors round out the usual list. Heat pumps have their own failure patterns. A defrost cycle that falls short lets ice build up on the outdoor coil, a bad reversing valve leaves the system stuck in cooling mode, and a dead outdoor unit hands the whole load to the electric backup strips, which cost several times as much to run.
Most of our service calls are for Furnace Repair. If something has stopped working, start there.
Warning Signs for Heating Repair
Recognizing the warning signs early can save you time and money. These are the signals our technicians see most often:
- Strange smells from the vents, especially rotten egg or burning
- Booming or banging at ignition, a sign of delayed burner light-off
- Higher heating bills with less comfort to show for them
- A furnace that tries to light, clicks, and then quits
- Cold air, or no air at all, when the thermostat calls for heat
- Uneven heat, with certain rooms that never warm up
- Thick ice or frost covering the heat pump outside
- The system starting and stopping every few minutes without warming the house
Don't Wait for a Total Failure
Most HVAC failures start small, a weak capacitor, a squealing blower, a system that runs a little longer each week. Call (901) 749-8008 at the first sign of trouble.
