Is sound an issue for heating and air conditioning? Yes. Loud heating and cooling equipment add to sound pollution. Although no cost savings are tied to lower sound levels, the sound rating of a cooling system can have a serious effect on comfort and enjoyment of your Kitchener home. The sound level of an air conditioner or heat pump depends on a variety of factors, such as the equipment, and the insulation of the compressor can contribute to the amount of noise it makes. Although many heating and cooling systems manufactured today are quieter now more than ever, it's a sound notion to compare sound ratings when assessing a new air conditioner or heat pump, particularly if the equipment location is near bedrooms or living rooms.
