I hope I can get some advice on the noise issue I'm having with my new Carrier gas furnace. The furnace was installed yesterday and it replaced a boiler with hydronic coil system and an air handler. The condenser unit was not replaced as it was 5 years old, it is single stage. This install was done by a Carrier Authorized dealer who is highly respected in my area.
There are 2 returns, one in the kitchen and one in the basement where the furnace is located. The noise issue seems to be coming from the furnace itself, and since the return is a straight shot up to the kitchen that area is very loud. We have tried different filters and also removing the grill in the kitchen return, the noise was quietest with a merv 12 Filtret filter and the grill back in place. So it seemed that muffling the sound made the noise better vs trying to improve the air flow which was what was suggested by the install people.
We took a decibel reading of the furnace and it was 68 near the furnace and 64 near the return in the kitchen. Does that seem too high or in the normal range?
I have been trying to figure out if my return in the kitchen is the correct size but I haven't been able to figure out how to do that calculation. Any tips here?
Tomorrow the rep from the company that did the install along with the foreman are coming to my home to look at everything so I wanted to be as prepared as possible.
Are there options for noise dampening the kitchen return? Should we consider replacing the outside compressor with a multi-stage unit? (not even sure if this is possible)
This is very disappointing because the return noise is so loud in the kitchen that it sounds as if the dishwasher is running and this was supposed to be a quite furnace.
Any tips or recommendations are greatly appreciated.
