Furnace runs but blows cool air
Often a dirty flame sensor or a failed igniter, both common after a long cold stretch.
Furnace RepairKalamazoo County holds a little of everything, from radiator homes in the city to ranch houses in the suburbs and propane farmhouses at the edges, and our technicians work on all of it.

Our main shop sits on S Rose Street in downtown Kalamazoo, close to the center of the county. That puts our vans within a short drive of the city neighborhoods, the townships ringing them and the smaller villages farther out. One phone line covers every call, day or night, and the technician who answers the service call is one of ours.
Most of the county runs on natural gas from Consumers Energy, but not all of it. Homes past the gas mains lean on propane, and a fair number of older city houses still heat with water or steam. We stock parts for furnaces, boilers, heat pumps and central air so the first visit can usually be the last one, even on a holiday weekend.
Inside the city of Kalamazoo, many early 1900s homes still carry cast iron radiators fed by a boiler in the basement. Those systems last for decades when the water level, valves and venting get regular attention. Our crews bleed radiators, rebuild circulators and replace worn zone valves, and we can swap an aging boiler for a high-efficiency model that keeps the original radiators in place. The radiators themselves rarely need replacing, so the upgrade stays in the basement and your walls and floors stay untouched.
Out in the post-war ranch neighborhoods and the newer subdivisions, the standard setup is a forced-air gas furnace paired with central air. Those homes see blower motors, flame sensors and igniters wear out first. Farther out, farmhouses and newer rural builds often burn propane, where a regulator or a sooty burner can stop heat cold. A fall furnace tune-up catches most of those parts before they fail, and it gives you a clear picture of how many winters the equipment has left.

Snow bands off Lake Michigan reach the county most winters, and clear nights can drop below zero. That combination keeps a furnace or boiler running close to nonstop for weeks, which is when weak inducer motors and cracked igniters give out. Summers swing the other way, with sticky July air that makes an undersized or low-charge air conditioner run long and still leave rooms damp. We plan our busiest months around both seasons.
Every Kalamazoo County call is dispatched from our S Rose Street office, and a real person picks up (269) 360-5258 at any hour, including holidays. We ask a few questions about the system and what it is doing, then send a technician with the parts that problem usually needs. For homes at the far edges of the county, we route the nearest van so you are not waiting on cross-town traffic.

Furnace & AC ReplacementFAQ
Yes. Our vans run to the villages and township roads across the county, not only the city limits. Rural homes often use propane or a well-pump setup that affects how we plan the visit, so tell us your fuel type on the call and we will send a technician who brings the right parts.
Most furnace repairs we see in the county land between $164 and $587, depending on the part. A flame sensor or igniter sits at the low end, while an inducer or blower motor costs more. The technician quotes the exact price after looking at your system and before any work starts.
In most homes, yes. A new high-efficiency boiler can connect to the existing radiator piping, so the cast iron stays in place. We check the piping, the expansion tank and the venting first, then size the new boiler to the heat loss of your house rather than matching the old unit by label.
