Heat pump or furnace? That is the first thing that matters when the heat quits in Chicago, IL, 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 usually 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.
Most of our service calls are for Furnace Repair. If something has stopped working, start there.
Signs You Need Heating Repair in Chicago
The sooner you notice these red flags, the easier and cheaper the fix. Watch for these telltale signs:
- The system starting and stopping every few minutes without warming the house
- No warm air at the registers even with the heat turned up
- Thick ice or frost covering the heat pump outside
- A loud boom when the burners light, which points to delayed ignition
- Uneven heat, with certain rooms that never warm up
- A furnace that tries to light, clicks, and then quits
- Energy costs climbing even though the house feels colder
- A rotten-egg, burning, or musty smell once the heat kicks on
