Regional HVAC Efficiency Standards

Do you meet HVAC Efficiency Standards?

Effective Jan 1st 2015 Regional Efficiency Standards apply to mini split AC, heat pumps, and packaged units. For the first time the efficiency level varies per state in which the equipment is installed.

The North, South and Southwest are required to meet the regional Efficiency Standards requirements. The U.S Department of Energy’s Regional Standards apply to all 2015 manufacture cooling equipment. The standards apply to single phase residential products only.

In compliance with the latest regional efficiency standards, 13 SEER 1-phase air conditioners are no longer available in the Southeast and Southwest regions of the United States. 13 SEER air conditioners remain legal for sale and installation in the North region, Canada, and for export. 13 SEER heat pumps are legal to sell and install throughout the US and Canada until inventories are depleted. Lennox does not honor warranties on systems illegally installed.
