The first hard freeze of the season is when Mount Prospect phones start ringing. Furnaces that limped through November finally give out, and the homes hit hardest tend to be the mid-century properties near the downtown Metra district and the Randhurst area, where original ductwork meets a third or fourth generation furnace.
Leith Heating and Cooling Inc repairs heating systems throughout Mount Prospect with certified technicians, clear pricing, and no pressure to replace something that can be fixed.
Mount Prospect furnaces fail in patterns tied to how these homes were built and remodeled. Finished basements often choke off return air, which sends the whole system into overheat protection. Additions built onto 1950s and 1960s floor plans get tied into duct trunks that were never sized for the extra square footage, so back bedrooms stay cold while the furnace runs constantly.
Add decades of ignition cycling and the result is a familiar list. Failed igniters, dirty flame sensors, tripped limit switches, tired blower motors, and heat exchangers reaching the end of a long service life.
No heat in a Chicago-area January is an emergency, and we treat it that way. Mount Prospect no-heat calls go to the top of our dispatch list, and our technicians arrive stocked for the failures that actually cause winter breakdowns.
Most emergency visits end the same day. We diagnose the fault, quote the repair before we start, and get the system cycling properly again before we leave. If a part has to be ordered, we tell you exactly when and what it will cost rather than leaving you guessing.
A furnace is a chain of components, and any weak link stops the heat. We service every one of them:
We replace what has failed and test the full cycle before calling the job finished.
Karen in Mount Prospect had a furnace that would light, run about ninety seconds, then drop out. Our technician traced it to a flame sensor caked with carbon buildup and an inducer pressure switch hose that had collected condensate. He cleaned the sensor, cleared and reseated the hose, and ran the furnace through four complete cycles to confirm the fix. Full heat, same visit, no replacement needed.
There are plenty of HVAC companies in the northwest suburbs. Here is what Mount Prospect homeowners get with us:
We would rather earn the next call than push a replacement you do not need today.

Yes. Condensing furnaces bring their own failure points, including clogged condensate drains, cracked PVC venting, and pressure switch faults tied to blocked intake or exhaust runs. Our technicians are trained and certified on both standard and high-efficiency equipment.
Once a year, in the fall, before the heating season starts. Annual service cleans the burners and sensor, inspects the heat exchanger, checks blower performance, and verifies every safety control. It is the single most effective way to avoid a midwinter no-heat call.
