When the heat goes out in Pontiac, MI, the clock starts ticking, and the diagnosis depends entirely on what kind of system is doing the failing. On a gas furnace, the single most frequent culprit is a flame sensor coated in oxide: the burners light, the sensor cannot prove the flame, and the board shuts the gas down three tries later and locks out. Close behind come cracked hot surface igniters, stuck pressure switches, clogged condensate traps on high-efficiency models, and blower motors that have quietly worn out. Heat pumps fail differently: a weak defrost cycle leaves the outdoor coil armored in ice, a failed reversing valve strands the system in cooling, and a dead outdoor unit leaves the electric backup strips carrying the whole house at several times the operating cost.

Warning Signs for Heating Repair
Spotting the early warning signs lets you act before the problem gets expensive. Keep an eye out for the following clues:
- Clicking and failed ignition attempts before the furnace gives up
- Burning, musty, or rotten-egg odors when the heat runs
- Short cycling every few minutes while the house stays cold
- Some rooms warm while others stay stubbornly cold
- Booming or banging at ignition, a sign of delayed burner light-off
- Energy costs climbing even though the house feels colder
- An outdoor heat pump coil that stays iced over
- The thermostat calls for heat but the vents blow cold air or nothing
Don't Wait for a Total Failure
What seems like a minor issue today can take out a compressor or heat exchanger tomorrow. If you notice any of these signs, call (248) 278-4190 for a prompt inspection.
