A bit of learning for you - Efficiency and Your HVAC System Most people want to choose a heating and cooling system that keeps their home comfortable throughout the year, and that often means ensuring that the system is properly sized. At the same time, though, you do not want to overspend on the energy it costs to heat and cool your home. That is where the following energy efficiency statuses come into play. The Department of Energy put these energy efficiency labels in place in order to help provide an equal way of comparing one system and product to the next, allowing property owners to make better decisions about what type of system is best suited for their needs. That does not always make it easy to know what the terms mean or how they play a role in the actual results you get. That is where our technicians come into play. When you contact us for a new heating and cooling system or because you are unsure of what something on your HVAC means, we are happy to offer insight and guidance to you. However, we also want to help you know the details because educating you is a big part of what we do. Here are some of the HVAC ratings explained: EER Energy Efficiency Ratio (EER) is one of the most common components you will see mentioned and it shows the efficiency of the system when it is operating at its peak load capacity. It is the power input in Watts and is calculated at 95/75 degrees DB/WB. In short, it is the ratio of the cooling capacity to the unit. IEER Integrated Energy Efficiency Ratio (IEER) is a more accurate representation of the actual efficiency you will get from your heating and cooling system. To create this figure, efficiencies are gathered at various loads, based on different temperatures, and then given weights to obtain an overall efficiency value. The peak load period will only count for about two percent of the overall value. SEER Seasonal Energy Efficiency Ratio (SEER) is another commonly used factor to determine efficiency. It is much like IEER above, but it is designed to be more representative of residential equipment compared to commercial systems. In all cases, it is another factor to compare. IPLV The Integrated Part Load Value (IPLV) is not often used when it comes to traditional residential equipment but instead for chillers. It is calculated in much the same way as IEER and provides a real-world efficiency comparison tool. It is worth taking a closer look at some systems. #icshvac Morris Sussex Sports #HVACEfficiency
