What Is SEER2 and HSPF2? Convert EER To SEER Rating (Calculator + Chart) - LearnMetrics However, the main difference between the two is that SEER2 accounts for changes in the average outdoor temperature and EER2 does not. The testing environment will reflect with better accuracy the type of static pressure registered inside a home. Since the goal of testing is to represent typical real-world conditions, DOE determined that SEER2s minimum static pressure requirement is more likely to represent actual conditions which is why the updates were made. At Budget Heating and Air Conditioning Inc., we are proud to be the leader in HVAC supplies, parts and equipment. Federal Register :: Energy Conservation Program: Energy Conservation Obviously, the cost of running any electric-powered air conditioner and heat pump, and the price of electricity per kWh matter as well. You can still own an air conditioner with less than the minimum SEER/SEER2 rating. Should A Dehumidifier Run Constantly 24/7? The difference in running cost is $76.94 per year. Low Superheat Normal Subcooling: 3 Causes + How To Fix AC? First, the basics. What Is Delta T In HVAC?
