Heat pump or furnace? That is the first thing that matters when the heat quits in St. Charles, MO, 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, we most often find cracked hot surface igniters, stuck pressure switches, clogged condensate traps on high-efficiency models, and blower motors at the end of their life.
The repair homeowners call us about most is Furnace Repair. That's the place to start if you need a fix today.
Signs You Need Heating Repair in St. Charles
The sooner you notice these red flags, the easier and cheaper the fix. Here are the most common indicators that it's time to call a professional:
- A rotten-egg, burning, or musty smell once the heat kicks on
- Frequent on-off cycles that never bring rooms up to temperature
- Uneven heat, with certain rooms that never warm up
- Higher heating bills with less comfort to show for them
- An outdoor heat pump coil that stays iced over
- Clicking and failed ignition attempts before the furnace gives up
- The thermostat calls for heat but the vents blow cold air or nothing
- Banging at startup caused by burners lighting late
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. If you notice any of these signs, call (636) 200-4658 for a prompt inspection.
