When the heat goes out in Tinley Park, IL, the clock starts running, 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 buried under frost, 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. Start there if your system isn't running right.
When to Call for Heating Repair in Tinley Park
The sooner you notice these red flags, the easier and cheaper the fix. Keep an eye out for the following clues:
- Thick ice or frost covering the heat pump outside
- The system starting and stopping every few minutes without warming the house
- Uneven heat, with certain rooms that never warm up
- Clicking and failed ignition attempts before the furnace gives up
- A rotten-egg, burning, or musty smell once the heat kicks on
- Cold air, or no air at all, when the thermostat calls for heat
- A loud boom when the burners light, which points to delayed ignition
- Higher heating bills with less comfort to show for them
Act Before It Gets Worse
A failing capacitor, clogged condensate drain, or dirty flame sensor rarely fixes itself and usually gets more expensive to address the longer it runs. If you notice any of these signs, call (708) 536-4739 for a prompt inspection.
