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 Port Sheldon homes and businesses. Mazure's Heating & Air Conditioning is just 30 minutes from our Jenison shop — fast response when you need it most.
Port Sheldon Township is quiet, rural, and right in the path of Lake Michigan's worst winter weather. Out here, houses are spaced apart, some roads don't get plowed as fast, and when your furnace goes down you can't afford to wait for a company that doesn't know the area. Mike Mazure has been servicing furnaces across Ottawa County since 1987. We make the 30-minute drive from Jenison to Port Sheldon regularly — including nights and weekends when emergencies hit.
We regularly serve homes in Port Sheldon Township — near Pigeon Creek Park and Lake Michigan shoreline. Our Jenison headquarters puts us just 30 minutes from our Jenison shop, which means fast emergency response when your system goes down unexpectedly.
Port Sheldon Township sits between Pigeon Creek Park and the Lake Michigan shoreline. That means heavy lake-effect snow, biting wind, and furnaces that run nonstop for months. A lot of homes out here are on larger lots with older heating systems that don't get serviced as often as they should. We see cracked heat exchangers, worn-out blower motors, and failed ignitors — problems that build up over years of hard use. Seasonal and vacation homes along the lakeshore are especially vulnerable. If a furnace sits idle all summer and then fires up cold in October, parts can fail from the thermal shock. We recommend a fall check-up for any Port Sheldon home, but especially seasonal properties. We work on Carrier, Lennox, Trane, Goodman, Rheem, and all the other major brands.
When you live 30 minutes from the nearest HVAC shop, you don't want to hear 'we need to order a part and come back Thursday.' We stock our trucks with the ignitors, capacitors, blower motors, and control boards that handle most residential furnace repairs. One trip is usually all it takes. Mike's approach is simple: tell people the truth. If your 18-year-old furnace needs a $400 repair but the heat exchanger is still solid, the repair makes sense. If the heat exchanger is cracked, we'll tell you it's time to replace the unit — and explain exactly why. No pressure, no scare tactics. Most furnace repairs in the Port Sheldon area cost between $150 and $500. Call (616) 669-8085 any time — we answer 24/7 for emergencies.

That burning smell on the first cold night is usually dust. How long it should last, and which smells mean shut it off or leave the house now.
