HVAC Installation Errors Lead to Efficiency Losses

Guidelines Needed to Improve HVAC Energy Efficiency

Sourceable, December 18, 2014

The push for more efficient air conditioners and heat pumps aims to significantly reduce the 30 per cent share of residential electrical energy use devoted to cooling and heating, but the benefits of improved energy efficiency ratings count for nothing if the equipment is not installed properly, the report says.

“Our measurements indicate that improper installation could increase household energy use for space heating and cooling in the order of 30 per cent over what it should be,” said Piotr Domanski, who leads NIST research on the performance of HVAC (heating, ventilation, and air conditioning) and refrigeration equipment.
