Furnace Inducer Motor Replacement in Marlborough, MA: What Homeowners Need to Know
When your furnace won’t fire up on a freezing Massachusetts morning, there’s a good chance the inducer motor is the culprit. It’s not a big part, but it has a critical job—and when it goes, your whole heating system shuts down as a safety precaution.
We recently tackled this exact issue for a homeowner in Marlborough, and our Endless Energy technician walked through the repair on camera. If you’re dealing with a furnace that won’t start or is making strange noises, this might be what’s going on with yours too.
What Your Furnace Inducer Motor Actually Does
Before your furnace can light, it needs to confirm that combustion gases can safely exit your home. That’s the inducer motor’s whole purpose. It pulls air through the heat exchanger, creates the right draft for safe combustion, and pushes exhaust fumes through your venting system. The sensors verify everything’s working properly before the furnace even tries to ignite.
If the pressure switch doesn’t sense proper airflow, your furnace won’t start. That’s by design—it’s keeping carbon monoxide from building up in your home.
Signs Your Inducer Motor Might Be Failing
Here in Massachusetts, we see homeowners calling with similar complaints pretty often. The furnace won’t start even though the thermostat is asking for heat. There’s a loud humming, grinding, or high-pitched squealing coming from the cabinet. Sometimes there’s a burning smell, or the heat works one day but not the next. You might also notice the furnace keeps cycling on and off or throwing error codes.
New England winters are tough on heating systems. We run our furnaces harder and longer than most of the country, which means parts like inducer motors tend to wear out faster here.
What Happened in This Marlborough Repair
The homeowner noticed their furnace was being inconsistent—sometimes it would start, sometimes it wouldn’t. And when it did start, there was an unusual noise during the startup sequence.
When our technician took a look, he found the inducer motor bearings were shot, draft levels weren’t consistent, and the pressure switch wasn’t staying closed like it should. The best fix? Replace the motor entirely.
The repair involved safely shutting down the system, pulling out the failed inducer assembly, and cleaning out the draft housing. Then came installing a new motor with a fresh gasket, checking pressure and airflow readings, and running the system through a full test cycle. The whole thing was done in one visit, and the house had heat again before the temperature dropped that night.
What Does This Repair Cost in Massachusetts?
Prices depend on your furnace brand, how old it is, and where it’s located in your home. But here’s what you can typically expect around here:
| Service | Typical Range |
|---|---|
| Inducer Motor Replacement | $450–$950 |
| Additional Draft/Vent Repairs | $100–$400 |
| Full Furnace Diagnostic | $129–$199 |
A lot of homeowners use this as an opportunity to get a full tune-up done at the same time, which can help the rest of the system last longer.
Can You Avoid This Problem?
To some extent, yes—especially if you stay on top of maintenance. Getting your furnace serviced every fall makes a big difference. So does changing your air filter regularly and keeping vents clear, especially after snow or ice storms. And if you hear unusual noises, don’t wait to call—catching small issues early can sometimes save the inducer motor from failing in the first place. If your furnace is getting older, it’s worth asking about Mass Save® rebates too.
