No two heating systems break the same way, and in Dearborn homes the first question on any no-heat call is what kind of equipment we are dealing with. Gas furnaces most often quit 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 traps the system 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.
The repair homeowners call us about most is Furnace Repair. If something has stopped working, start there.
When to Call for Heating Repair in Dearborn
Recognizing the warning signs early can save you time and money. These are the signals our technicians see most often:
- No warm air at the registers even with the heat turned up
- Strange smells from the vents, especially rotten egg or burning
- Energy costs climbing even though the house feels colder
- Banging at startup caused by burners lighting late
- Uneven heat, with certain rooms that never warm up
- Short cycling every few minutes while the house stays cold
- A heat pump's outdoor unit encased in frost or ice
- The furnace clicking and trying to light but shutting back down
