Single family houses, townhomes, and condo buildings sit side by side across Glendale Heights, and each type brings a different heating setup. A townhome furnace tucked into a utility closet has almost no room for airflow error, while the detached homes off Army Trail Road run full-size systems in basements built in the 1970s and 1980s.
Leith Heating and Cooling Inc services all of them, with NATE-certified technicians and a price agreed on before the repair starts.
Tight installations and aging equipment drive most of our DuPage County calls. In townhomes and condos, furnaces sit in closets with limited combustion air and shared venting, so a small restriction becomes a lockout quickly. Filters get neglected because the unit is out of sight, and the resulting overheating trips the limit switch again and again.
In detached homes, the pattern runs older. Worn igniters, tired blower motors, fouled flame sensors, and heat exchangers reaching the end of a long service life account for most repairs.
Losing heat in a DuPage County January is not an inconvenience, it is a plumbing risk. Glendale Heights no-heat calls move to the top of our dispatch board, and we get a technician out the same day whenever there is capacity.
We arrive with the ignition, sensor, and control parts that cause the majority of winter breakdowns. Most calls end with heat restored on the first visit, and if a component has to be ordered you get the timeline and the price before we leave.
Our technicians service every component in a residential gas furnace:
In closet and utility room installations we also verify combustion air and venting, since those often cause the fault in the first place.
Priya in Glendale Heights had a townhome furnace that kept locking out overnight and resetting itself by morning. Our technician found the filter completely loaded and the closet louver blocked by stored boxes, starving the unit of combustion and return air. He replaced the filter, cleared the airflow path, cleaned the flame sensor, and tested several full cycles. The lockouts stopped that night.

A brief dusty smell at the first startup of the season is normal as dust burns off the heat exchanger. A persistent burning smell, an electrical odor, or anything acrid is not. Shut the system down and have it inspected before running it again.
Yes, especially for closet and utility room installations where problems develop out of sight. Annual service cleans the burners and sensor, checks the heat exchanger, verifies airflow, and tests safety controls, which prevents most of the midwinter failures we respond to.
