Is there a way to insulate my heat/air closet?

Question

The unit is recently installed and the closet is at the end of the entry adjacent to the living/dining area. My downstairs is so small and it is noisy when the unit comes on. My entry is tile, the closet floor is cement, the l/d room carpet. The wooden door on the heater closet has slats for ventilation.

Answer 1

Without knowing where you are I offer this.

In the USA in home improvement stores, is sold industrial/commercial/residential sheet foam, designed to insulate.

It can also serve as a sound deadening device. Often its tight bead structural foam, often light blue in color and easily managed with a utility knife. It's sold in various thicknesses up to 3"

It can be attached to walls and ceiling with Liquid Nails or other construction adhesives, with a caulking gun.

The issue as explained is that the unit and its space need ventilation and the VENT should be left open to allow that. Still the foam will help. ALSO since the floor is concrete you can buy carpet and cut a piece to fill the open areas of the concrete floor aiding in sound absorbtion.

Answer 2

dont put Styrofoam on the walls. if you get a little dust fire (it happens on occasion) the Styrofoam will ignite and that stuff burns like napalm. in fact, most building codes, and good common since say that a furnace closet cant have anything on the walls but sheet rock. a small furnace room isn't even supposed to have anything else stored in it (like a broom)

you might call the installers, and explain the situation to them, and ask if maybe they could decrease the fan speed. this will help with the roar.
