Heat pump or furnace? That is the first thing that matters when the heat quits in Sterling Heights, MI, 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.
When to Call for Heating Repair in Sterling Heights
The sooner you notice these red flags, the easier and cheaper the fix. 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
- Cold rooms in one part of the house while others are comfortable
- A loud boom when the burners light, which points to delayed ignition
- No warm air at the registers even with the heat turned up
- The system starting and stopping every few minutes without warming the house
- A heat pump's outdoor unit encased in frost or ice
- A furnace that tries to light, clicks, and then quits
Act Before It Gets Worse
Most HVAC failures start small, a weak capacitor, a squealing blower, a system that runs a little longer each week. Call (586) 204-2359 at the first sign of trouble.
