What energy efficiency ratings mean and why they’re important01/10/2017 More than half of your utility bills in Napoleon and Northwest Ohio can be attributed to the cost to heat and cool your home. To save as much money as you can, you should find a system that can deliver 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 a handful 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 indicate better energy efficiency, and therefore, more affordable utility bills. For cooler northern states, The Department of Energy requires a minimum 13 SEER rating. Warmer, southern states must have a 14 SEER-rating minimum. If your unit has a lower SEER-rating, an upgrade could bring you a helpful spike in energy savings. AFUE or HSPF (used to measure heating efficiency: gas or electric) Annualized Fuel Utilization Efficiency (AFUE) ratio identifies the percentage of heat produced for every dollar of fuel consumed—just like 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 escaping through venting. The Heating Seasonal Performance Factor (HSPF) measures the heating efficiency of heat pumps. It is essentially the SEER rating for winter since it measures only heating efficiency. Like the other ratings, higher numbers denote better energy efficiency. At Von Deylen Plumbing & Heating Inc., 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 its efficiency and save money—whether with continued maintenance or with new, more efficient equipment.
