Heat pump or furnace? That is the first thing that matters when the heat quits in Louisville, KY, because the two fail in completely different ways. Heat pumps tend to freeze up when defrost stops working, get stuck in cooling when a reversing valve fails, or quietly lean on the electric backup strips, at several times the normal operating cost, when the outdoor unit dies. Gas furnaces typically come down to the flame sensor: once oxide coats it, the burners light but the flame cannot be proven, so the board cuts the gas and locks out after three tries. After that, the usual suspects are cracked hot surface igniters, stuck pressure switches, clogged condensate traps on high-efficiency models, and blower motors at the end of their life.
Most of our service calls are for Furnace Repair. Start there if your system isn't running right.
Warning Signs for Heating Repair
Catching these issues early helps you avoid costly problems. These are the signals our technicians see most often:
- Higher heating bills with less comfort to show for them
- A rotten-egg, burning, or musty smell once the heat kicks on
- The thermostat calls for heat but the vents blow cold air or nothing
- Banging at startup caused by burners lighting late
- Clicking and failed ignition attempts before the furnace gives up
- A heat pump's outdoor unit encased in frost or ice
- The system starting and stopping every few minutes without warming the house
- Cold rooms in one part of the house while others are comfortable
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. At the first hint of a problem, call (502) 844-8263 for a fast inspection.
