What energy efficiency ratings mean and why they’re important01/10/2017 More than half of your utility bills in Bountiful are comprised of the cost to heat and cool your home. To save as much money as you can, you need a system that can supply home comfort as efficiently as possible. The better your system’s energy efficiency, the more your system is doing while using less energy. If you’re preparing to upgrade or replace your HVAC equipment, you should understand certain terms and ratings to be fully informed and get the best energy efficiency possible. SEER (used to measure cooling efficiency) The Seasonal Energy Efficiency Ratio, or SEER, rating calculates the cooling efficiency of your equipment at different temperatures. Higher SEER ratings indicate 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 must have a SEER rating of 14 or higher. If your unit has a smaller SEER-rating, an upgrade could bring you a beneficial spike in energy savings. AFUE or HSPF (used to measure heating efficiency: gas or electric) Annualized Fuel Utilization Efficiency (AFUE) ratio measures the percentage of heat produced for every dollar of fuel expended—just like 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 generated 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 in essence the SEER rating for winter because it measures only heating efficiency. Like the other ratings, higher numbers mean better energy efficiency. At Craig's Appliance Heating & Cooling, you’ll find equipment with top energy efficiency ratings. We can help you verify the energy efficiency of your current equipment and help you find ways to improve that efficiency and save money—whether with regular maintenance or with new, more efficient equipment.
