The Consortium for Energy Efficiency (CEE) and Energy Star has issued new guidelines for efficiency tiers for residential single phase air conditioner and heat pump equipment to better align with the DOE’s new regional standards which went into effect in Jan 2015.
The air conditioning and heat pump efficiency regulations that went into effect on January 1, 2015 will only affect new equipment, including both the indoor and outdoor units. General repairs to an existing system should not be affected unless the whole indoor or outdoor units are replaced.
One of the items that is often overlooked during the planning and construction of a new home is the potential for an enhanced air conditioning (A/C) system. In many cases, the new homeowner is not aware of the various system options available beyond the system that comes standard with the house.
