What is an Energy Audit?

An energy audit is a scientific assessment of your home’s systems and how well they work together to keep your home comfortable, healthy and energy efficient. We examine all the components in your home, including:

•Envelope — your home’s exterior walls, roof, attic, ceilings and basement

•Heating & cooling systems — furnace, boiler, central air conditioning, heat pump

•Ductwork— metal duct system that directs conditioned air throughout your home

•Insulation — located in the attic, walls and foundation, this material resists heat transfer

These major systems work together to keep your Garden City, NY region home comfortable. When there’s a breakdown in one or more of these elements, your home will be less comfortable and less efficient.
