Answer:
Manufacturers publish equipment efficiency ratings which are available to your contractor. ARI also publishes directories indicating various energy efficiency ratings of specific equipment. It is important that a contractor install a unit that has just the right capacity to cool your home. Units with excess capacity will cycle on and off and work less efficiently, thus increasing your operating costs.
