Thermostat screen blank or not responding in Grand Rapids? Here are 6 quick fixes to try before calling for HVAC service.

Professional furnace repair for Jenison homes and businesses. Mazure's Heating & Air Conditioning is right here in our home base of Jenison — fast response when you need it most.
Our shop sits on Edward Street in Jenison, which means when your furnace stops working on a cold January night, we don't have to drive across town to reach you. Mazure's Heating & Air Conditioning has been fixing furnaces for Jenison homeowners since 1987. Mike Mazure still answers the phone, still runs the calls, and still treats every Georgetown Township home like it belongs to a neighbor — because it does. Call (616) 669-8085 any time, day or night, and you'll talk to us directly.
We regularly serve homes in Georgetown Township, Baldwin Heights, Cottonwood — near Jenison High School and Rosewood Park. Our Jenison headquarters puts us right here in our home base of Jenison, which means fast emergency response when your system goes down unexpectedly.
Jenison's housing stock runs the full range — 1970s ranches along Baldwin Street, split-levels near Rosewood Park, and newer builds out past Cottonwood Drive. Each era of home brings its own furnace quirks. Older homes in Georgetown Township often still have 80% AFUE furnaces that were fine twenty years ago but now struggle with worn-out ignitors, cracked heat exchangers, and aging blower motors. Newer developments tend to have high-efficiency condensing furnaces (90%+ AFUE) where the most common failures involve clogged condensate drains, pressure switch errors, and circuit board issues.
We work on every major brand — Carrier, Lennox, Trane, Goodman, Rheem, York, and American Standard. If it heats air and pushes it through ducts, we've fixed it. The most frequent calls we get from Jenison homes involve furnaces that short-cycle (turn on, run a few minutes, shut off, repeat), furnaces blowing cold air, strange banging or squealing noises at startup, and pilot light or ignition failures. Most of these repairs run between $150 and $500 depending on the part involved.
One thing we always do: tell you exactly what we find before we touch anything. If your heat exchanger is cracked, we'll show you. If a $12 flame sensor cleaning fixes the problem, that's all we'll charge you for. We don't invent problems to pad the bill.
We're not driving in from Kalamazoo or dispatching from a call center in Ohio. Our shop is right here on Edward Street in Jenison, 49428. When you call (616) 669-8085, Mike picks up. Not a receptionist. Not an answering service. The guy who's going to fix your furnace.
That matters when it's 11 PM and your house is dropping below 55 degrees. Our response time to anywhere in Jenison is measured in minutes, not hours. Baldwin Heights, Cottonwood, the neighborhoods around Jenison High School, the homes along 8th Avenue — we know these streets because we live here.
After 37 years of serving Georgetown Township, we've built our reputation on doing honest work at fair prices. We recommend repairs when repairs make sense. We recommend replacement when the math says repair costs will exceed what a new furnace would give you in efficiency savings and reliability. We don't push equipment you don't need.
Every repair comes with a clear explanation of what failed, why it failed, and what you can expect going forward. If your furnace is 22 years old and needs a $400 part, we'll have a straight conversation about whether that's good money or whether it's time to look at a new unit. Your call, not ours.
Michigan winters don't wait for business hours, and neither do we. Mazure's offers 24/7 emergency furnace repair for Jenison and all of Georgetown Township. Because our shop is local, we can typically reach your home faster than any other HVAC company in the area. No long waits, no 'we'll be there sometime between 8 and noon' windows.
Before we arrive, here's what you can check: Is your thermostat set to heat and turned above room temperature? Has the furnace filter been changed in the last 90 days? A completely clogged filter can shut a furnace down through the high-limit safety switch. Is the gas valve open? Is the breaker tripped? These simple checks solve about 15% of the emergency calls we get.
If those basics don't get it running, call us. We stock common parts on the truck — ignitors, flame sensors, blower capacitors, pressure switches, gas valves, and control boards for the most popular brands. That means most emergency repairs get finished the same night, not 'we'll order the part and come back Thursday.'
We've been Jenison's furnace repair company since before some of these subdivisions were built. The families on these streets know our name because we've kept their homes warm for decades.
