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.

When your furnace stops working in a Michigan winter, you need someone who answers the phone — day or night. Mazure's has been repairing furnaces across the Grand Rapids area since 1987. We service all makes and models, and we don't upsell you on a replacement when a repair will do the job.
Furnace won't ignite, short cycling, blowing cold air, strange noises, pilot light issues, thermostat malfunctions, blower motor failures, cracked heat exchangers, clogged filters causing shutdowns, and ignitor replacement. We carry common parts on our trucks for same-visit repairs whenever possible.
We repair Carrier, Lennox, Trane, Goodman, Rheem, Ruud, York, American Standard, and every other major furnace brand. Whether your system is 2 years old or 20, we have the experience to diagnose and fix it correctly the first time.
A furnace failure at 2 AM in January isn't something that can wait until Monday. Call us any time — Mike or a member of our team will answer and get you scheduled for emergency service. We prioritize no-heat calls to get your family safe and warm as quickly as possible.
We'll tell you exactly what's wrong and what it costs to fix before we start any work. If a repair doesn't make economic sense, we'll explain your replacement options honestly — but we never push a sale when a straightforward repair is the right call.
We provide furnace repair service across the greater Grand Rapids area. Select your city for local details.
