HAAS Consideration: Installing a high efficiency heating and cooling system in a home before addressing air leakage issues or upgrading insulation may result in the installation of an oversized heating system that does not provide the energy savings or comfort expected. Undersized equipment may leave occupants with a heating system that does not heat the home adequately, is expensive to operate, and may not last long. The improper installation of heating systems may severely impact efficiency and performance.
