When the heat goes out in Elgin, IL, the clock starts ticking, and the diagnosis depends entirely on what kind of system is doing the failing. On a gas furnace, the most common no-heat call we run 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.
Most of our service calls are for Furnace Repair. If something has stopped working, start there.
Warning Signs for Heating Repair
Recognizing the warning signs early can save you time and money. Watch for these telltale signs:
- Heating bills spiking while comfort keeps falling
- Clicking and failed ignition attempts before the furnace gives up
- Cold rooms in one part of the house while others are comfortable
- Strange smells from the vents, especially rotten egg or burning
- Cold air, or no air at all, when the thermostat calls for heat
- The system starting and stopping every few minutes without warming the house
- Banging at startup caused by burners lighting late
- A heat pump's outdoor unit encased in frost or ice
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. At the first hint of a problem, call (224) 395-7018 for a fast inspection.
