How can I quiet down my forced air heater

[greenhead4u]

I have a standard stock forced air heater in my 2008 ice castle. It is mounted under the stove so its close to the floor. I feel like it is loud and makes alot of noise and would like to quiet it down. Its not squeeky or humming or sounding sickly, its more that the fan blows a ton of air out and it resinates all that sheet metal sounding like we are planning to dry out everybodys floor on the lake. Does anybody else get annoyed with this and do you have any solutions?

I considered possibly spraying foam to try and sound proof it a bit. Any ideas or input would be greatly appreciated.

That is strange. I was in an Ice Castle last winter and you could barely hear the heater running. Is that the Suburban or Atwood? Front discharge, or ducted?

i had a forced air furnace in my last house and got rid of it just for that reason. I t would wake me up at night. Was hard to hear the tv. It did keep the heat evenly distributed which was nice. Now I am back to a ventless heater. Very efficient and uses no battery. I just crack a window

Hmmm....I'm only days away from installing one in my new house. Now you've got me re-thinking.

I went with the Suburban 16k BTU, which was in the Ice Castle I was in last year. That one was quieter than my computer fans and put off some really nice even heat.

I had a suburban forced air. It was not really that loud but when out on the ice it seams that everything is magnified. I just had a hard time sleeping when it would kick on and off... Nice even heat though

Depending on how much of the paneling/cupboards/case around it you can remove. I would try to get it making the noise (turn it on), then press on various parts of the sheet metal or duct. it might just be vibrating (resonating like you said) on something and need some rubber washers, glue, sheet metal screw, etc to get it to quit vibrating.

you could try some rubber auto sound deadener like Dynamat. You could possibly buy some scrap or small amount from a car stereo installer.

I can see how that could be. I was a bit worried after reading this post today so I just went and hooked mine up to a battery to see if I was making a mistake (I HATE noise). Out of any sort of enclosure it was equally as loud as 2 computer fans, but not quite as high pitched. I think I can live with that. The furnace shouldn't run real often as the house is getting a lot of spray foam.

That said, I will be rethinking my front cabinets to accommodate rubber mounts and an insulated enclosure/ ducting to keep things as quiet as possible.

Mine is the Atwood model. Im wondering if the ducted models are less noisey? You hit it right on the money with having to turn the TV up all the time and getting woke up when it kicks on at night. hmmmmmmmm what to do?

i have a suburban furnace in mine also. it was so loud i had to turn it off to watch tv. mine is mounted in the center of the house about 4 feet up. i purchased a sheet of sound deadening material somewhere & built a box around it. can bearly hear it now. i would think spray foam would do the same thing. i think i got the sound material at one of the premium lumber yards.
