HVAC Efficiency

HVAC EFFICIENCY – A rating on comfort equipment, a measure of its energy usage to heating and cooling efficiency.

The U.S. Small Business Administration notes that HVAC equipment accounts for 40 percent of energy usage in commercial buildings.

Heating and cooling efficiency is the most effective way that people can decrease their overall energy consumption.

Setting your thermostat closer to the temperature outside will save you quite a bit and increase your HVAC energy efficiency. When it's hot outside, a HVAC system set at 75 degrees will use 18% more energy than one set at 78 degrees. And setting it at 72 degrees uses 39% more energy than 78 degrees.
