What energy efficiency ratings mean and why they’re important



SEER (used to measure cooling efficiency)
The Seasonal Energy Efficiency Ratio, or SEER, rating measures the cooling efficiency of your equipment at various temperatures. Higher SEER ratings denote better energy efficiency, and therefore, smaller utility bills. For cooler northern states, The Department of Energy requires a minimum 13 SEER rating. Warmer, southern states must a minimum SEER rating of 14. If your unit has a smaller SEER-rating, an upgrade could bring you a valuable spike in energy savings.

Annualized Fuel Utilization Efficiency (AFUE) ratio identifies the percentage of heat produced for every dollar of fuel expended—similar the miles per gallon you get from your car. Higher AFUE ratings translate into lower energy costs. So, an AFUE rating of 80 means that 80% of the heat produced by your furnace is heating your home, and 20% of the heat is wasted through venting.

The Heating Seasonal Performance Factor (HSPF) measures the heating efficiency of heat pumps. It is fundamentally the SEER rating for winter given that it measures only heating efficiency. Like the other ratings, higher numbers mean better energy efficiency.

At Mitchell Heating, you’ll find equipment with the best energy efficiency ratings. We can help you verify the energy efficiency of your current equipment and help you find ways to improve its efficiency and save money—whether with regular maintenance or with brand new, more efficient equipment.
