Is sound an issue for heating and air conditioning? Yes. Loud heating and cooling equipment increase sound pollution. Although no cost savings are tied to a quieter home environment, the sound rating of a cooling system can have a considerable effect on comfort and enjoyment of your Denver home. The sound level of an air conditioner or heat pump depends on a variety of factors, such as the age and make of the equipment, and whether the compressor is insulated or not can contribute to the amount of noise it makes. Although many heating and cooling systems built today are quieter than they ever have been, it's a good thought to compare sound ratings when assessing a new air conditioner or heat pump, particularly if the equipment location is near bedrooms or living rooms.
