Homeowners are concerned with the efficiency of the appliances they purchase and install in their homes.

When it comes to air conditioning and heat pump systems, there are several specific efficiency stats you’ll want to pay attention to when planning a new HVAC installation. The three ones we’ll address here are EER, SEER, and HSPF.
