Do high efficiency systems have lower operating costs?
Yes, the initial investment may be more, but your long-term savings may be significant. Manufacturers publish equipment efficiency ratings which are available to your contractor. The Air Conditioning and Refrigeration Institute 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.
