What energy efficiency ratings mean and why they’re important01/10/2017 More than half of your utility bills in Pacheco consist of cost to heat and cool your home. To save as much money as you can, you should find a system that can provide 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 assesses the cooling efficiency of your equipment at various temperatures. Higher SEER ratings signify better energy efficiency, and therefore, lower utility bills. For colder 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 poor SEER-rating, an upgrade could bring you a valuable spike in energy savings. AFUE or HSPF (used to measure heating efficiency: gas or electric) Annualized Fuel Utilization Efficiency (AFUE) ratio shows the percentage of heat produced for every dollar of fuel used—similar the miles per gallon you get from your car. Higher AFUE ratings usually mean 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 lost through venting. The Heating Seasonal Performance Factor (HSPF) measures the heating efficiency of heat pumps. It is fundamentally the SEER rating for winter because it measures only heating efficiency. Like the other ratings, higher numbers mean better energy efficiency. At Clean Air HVAC, you’ll find equipment with top energy efficiency ratings. We can help you determine 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 up-to-date, more efficient equipment.
