Is sound an issue for heating and air conditioning?

Yes. Loud heating and cooling equipment increase sound pollution.While no monetary savings are tied to lower sound levels, the sound rating of a cooling system can have a considerable effect on comfort and enjoyment of your Waldorf home. The sound level of an air conditioner or heat pump depends on a number of things, such as the unit, and the insulation of the compressor can contribute to the amount of noise it makes.

Although many heating and cooling systems built today are quieter than ever before, it's a sound  thought to compare sound ratings when shopping for a new air conditioner or heat pump, particularly if the equipment location is near bedrooms or living rooms.
