Furnace Blowing Cold Air? Here's What's Going On
Furnace running but blowing cold air? Start with the free thermostat fix, then the filter, ignitor, and drain causes — and know where to stop and call.

Professional furnace repair for Walker homes and businesses. Mazure's Heating & Air Conditioning is just 18 minutes from our Jenison shop — fast response when you need it most.
A furnace that quits on a January night in Walker doesn't wait for business hours. Mazure's Heating & Air Conditioning has been fixing furnaces across West Michigan since 1987, and we respond to emergency calls in Walker — including the Alpine Avenue corridor and Standale — the same way we respond in our home base of Jenison. Mike Mazure still answers the phone, and our shop is just 18 minutes south on the highway. No dispatch center, no runaround.
We regularly serve homes in Alpine Avenue corridor, Standale — near Alpine Avenue and Walker Ice & Fitness Center. Our Jenison headquarters puts us just 18 minutes from our Jenison shop, which means fast emergency response when your system goes down unexpectedly.
The housing stock along Alpine Avenue and through the Standale neighborhoods includes a lot of mid-century ranches built in the 1950s and 60s. Those homes have seen multiple furnace replacements, and the systems currently running tend to be 15 to 25 years old. We see the same issues repeat: ignitors that crack after thousands of heat cycles, blower motors that overheat and shut down, flame sensors coated in residue, and thermostats that lose communication with the control board. Newer subdivisions west of Alpine have their own problems — builder-grade furnaces that were sized for cost rather than comfort, leading to short cycling and uneven heating. We work on all major brands, including Carrier, Lennox, Trane, Goodman, Rheem, and York. Our truck carries the most common parts, so most repairs finish in a single visit. If your furnace is blowing cold air, making banging or squealing sounds, or cycling on and off every few minutes, call us at (616) 669-8085.
We don't charge a diagnostic fee and then hit you with a separate repair quote. Here's what happens: we show up, listen to what you've noticed, and inspect the system from the thermostat signal all the way through to the exhaust vent. We check gas pressure, test the ignitor and flame sensor, inspect the heat exchanger for cracks, measure airflow, and look at the blower assembly. Then we tell you what's wrong, what it costs to fix, and whether the repair makes sense given the age of your equipment. If your furnace has a cracked heat exchanger, we'll tell you straight — that's a safety issue, and repair isn't the right call. But if it's a $200 ignitor swap on a 10-year-old Carrier, we'll have you back up and running before we leave. Most repairs for Walker homeowners run between $150 and $500, depending on the part.
Walker sits right on the edge of Grand Rapids, and there's no shortage of HVAC companies advertising along Alpine Avenue. The difference with Mazure's is simple: you talk to the owner. Mike has been doing this work for almost four decades. He doesn't push replacements when a repair will hold. He doesn't send a salesperson to your door. If you call our number, you get a straight answer about what's going on with your furnace and what it'll cost to fix. We're a family operation out of Jenison — close enough to reach Walker in under 20 minutes, small enough that we remember your name and your equipment. We also offer 24/7 emergency service, because furnaces don't break on a convenient schedule.
