When it comes to heating and cooling we strive to bring you the latest news and information available to the industry on behalf of your heating installation and sales in St Louis near Bridgeton MO. Today, we flip a coin and go from discussing St Louis Heating Sales to central air conditioners. “Central air conditioners and air-source heat pumps operating in the cooling mode have been rated according to their seasonal energy efficiency ratio (SEER) since 1992.” Many people are clueless when it comes to the ratings of their systems and, mainly when they are shopping, this can be quite pertinent information to have. So, let us describe some of the nitty gritty surrounding these numbers as they pertain to your St Louis Heating and Cooling maintenance and efficiency.
“SEER is the seasonal cooling output in BTU divided by the seasonal energy input in watt-hours for an ‘average’ U.S. climate. Before 1992, different metrics were used, but the performance of many older central air conditioners was equivalent to SEER ratings of only 6 or 7.” This number has risen over time with the average central air conditioner sold in 1988 having a SEER-equivalent of about 9; then by 2002 it had risen to 11.1.
According to our research done recently on behalf of your St Louis Heating and Cooling sales near Bridgeton MO, the national efficiency standard for central air conditioners and air source heat pumps now requires a minimum SEER of 13, this has been the case since 2006. Also, you cannot just receive an ENERGY STAR rating without working for it in the heating and cooling world. This title is only awarded to systems who achieve a minimum of 14.5 SEER. Basically, the point of our post is to recognize the efficiency differences and the fact that they do exist in the AC and heat pump world. Also, knowing a bit about their significance can and does make you a smarter shopper in the world of HVAC.
