Can Sound Absorbing Mats Reduce Noise from Central Heat & Air Units?

In summary, the conversation discusses the issue of a loud central heat and air unit in the living room and possible solutions to reduce the noise. Suggestions include adding sound insulation to the inside of the closet, using active cancellation, and mounting the equipment on dampening supports. It is also mentioned that the noise is generated by the blower wheel moving the air and that sound absorbing mats can be used to line the unit's enclosure.

I have a central heat and air unit enclosed in a closet like area and it is very loud in my living room,
is there a way to install a noise cancelling unit to muffle that sound of the blower unit?

Welcome to the PF, Marty. :smile:

Active cancellation might work, but have you considered adding sound insulation to the inside of the closet? You might try that approach first, and then try adding active cancellation if the insulation does not help enough.

And you could consider mounting the equipment on dampening supports, to lower the mechanical coupling to your home's floor and walls...

Thanks everyone, I will locate some sound absorbing mats and line the units enclosure and see how that goes.
