Residential Service
Cleaning furnaces the right way since 1956 — truck-mounted power, honest answers, free estimates.
What You Get
Most of what slows a furnace down is packed onto the blower wheel and settled across the burner compartment and return drop. We open the equipment up and clean those surfaces with truck-mounted suction, so the dust leaves the house instead of moving to a different part of it.

Boot covers, clean runners, and drop cloths before anything is opened up.
02
The vacuum lives on the truck, so dust and debris go out of the house instead of recirculating inside it.
03
Blower wheel, burners, heat exchanger surfaces, cabinet, and return drop — brushed loose and pulled out under suction.

You look at the equipment before we close it up. If something needs an HVAC tech, we tell you plainly.
Cleaning the furnace and cleaning the ductwork usually go together — see air duct cleaning or what it costs.
Furnace Cleaning FAQs
We clean the blower wheel and motor housing, the burners and burner compartment, the accessible heat exchanger surfaces, the furnace cabinet, and the return drop where most of the dust collects. We also check the filter and show you what came out before we pack up.
It depends on the system, how many vents feed it, and how accessible the equipment is, so we quote each job rather than publish a flat rate. A complete whole-home cleaning that includes the furnace runs $450–$1,000 for an average Central Illinois home. Estimates are free, the price we quote in writing is the price you pay, and we'll beat a comparable written competitor quote by 10%. Call (309) 472-5036 for your number upfront.
Combined with a full duct cleaning, plan on 2–4 hours for an average Central Illinois home. A furnace-only visit is shorter — we'll tell you the window when we quote the job.
For most Central Illinois homes, once a year before heating season. Homes with pets, recent remodeling, or heavy dust may benefit from more frequent cleaning.
No. We are a cleaning company, not an HVAC repair contractor. We remove the soot, dust, and debris that make a furnace work harder. If we find a mechanical or safety problem, we tell you straight and recommend an HVAC technician — we do not sell you repairs, installations, or replacements.
That burnt-dust smell is usually dust that settled on the heat exchanger and blower over the summer burning off. A thorough cleaning before heating season removes it. If the smell is more like gas or a persistent burning odor, shut the system down and call an HVAC technician immediately.
A dirty blower wheel and clogged return restrict airflow, which makes the furnace run longer to reach the same temperature. Cleaning restores airflow. We won't promise a specific dollar savings — every home and system is different.
