 Building Performance Certification 

Of what use is a high-efficiency heating and cooling system when your home is leaking air from windows, doors, or from aging or poorly designed duct work . . . or when a poorly ventilated attic traps heat and spills it into your living space.

Stan Perkoski is certified in our industry's most advanced building efficiency science. He's trained his technicians and advisors to look beyond your furnace, boiler, air conditioning or heat pump and to consider them as only part of a complex system responsible for your home's comfort and energy-efficiency.

Most heating/cooling companies have but one answer to your heating/cooling complaints: "Replace your old system with a new high efficiency one." Sometimes that is the right call, but if there are other issues responsible for inefficiency and discomfort, Stan Perkoski's team will identify the problem and work with you to find a solution. If we can't do the work ourselves, we'll help you find someone who can.
