When the heat goes out in Palatine, IL, the clock starts running, 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.
The repair homeowners call us about most is Furnace Repair. Start there if your system isn't running right.
Warning Signs for Heating Repair
Spotting the early warning signs lets you act before the problem gets expensive. Watch for these telltale signs:
- Short cycling every few minutes while the house stays cold
- Banging at startup caused by burners lighting late
- A heat pump's outdoor unit encased in frost or ice
- Energy costs climbing even though the house feels colder
- No warm air at the registers even with the heat turned up
- A rotten-egg, burning, or musty smell once the heat kicks on
- Some rooms warm while others stay stubbornly cold
- Clicking and failed ignition attempts before the furnace gives up
