When you purchase a new Air Conditioning system, you expect high performance. Unfortunately, more than half of the new HVAC systems in US homes do not perform to their rated efficiency as a result of improper installation. In fact, an improper AC installation can reduce performance by as much as 30%. This not only affects your utility bills, but can lead to a variety of home comfort problems, including insufficient dehumidification, dust from leaking ductwork, and poor air distribution
Ask the AC contractors bidding for your business if they follow ENERGY STAR® Quality Installation Guidelines (www.energystar.gov/qispec) to ensure that you are not buying just a piece of equipment but a properly installed heating and cooling system that provides comfort and efficiency.
