New Carrier furnace Inducer motor Hum wakes us up at night

Hello,

I have recently had a new Carrier furnace installed by an authorized HVAC technician. As it has gotten colder in the Midwest we are starting to use our furnace a lot more. We noticed that there is a humming noise that can be heard reverberating in our house especially our bedrooms upstairs. The noise is waking us up at night. I spoke with our technician and he came out immediately and replaced the inducer motor which seems to be the cause of the noise. He mentioned our previous furnace did not have an inducer motor. The replacement has not fixed the problem. I noticed that if i put pressure on the shroud of the motor, the humming noise is drastically reduced. My technician has stated that the noise is a normal part of the new furnace and we would need to get used to the noise. Every time the furnace turns on in the middle of the night, I am woken up. I'm not sure I will be able to sleep with it running more often as temperatures get colder? Please Help!?!

Thanks,

Daniel Kemling

Yeah, it is tough to get used to the noises some of the new furnaces make. Some worse than others. Inshot burners in an open nacelle are another complaint I got when they first came on the market in the 90's.

You probably have a lovely hard piped gas line and a crisp metal duct as well that do a bang up job of transmitting the noise. There are a few things that can be don if it is too annoying to get used to, but they can run into some bucks, especially if the furnace is in a closet on the main floor...

Noise factor (as well as comfort) is one of the reasons I always push modulating input gas furnaces with VS blowers. They are quiet...
