When choosing an HVAC system, efficiency is a crucial thing to consider. More efficiency adds up to better performance, reliable comfort, and increased savings. Understanding HVAC efficiency ratings will help you decide which systems will provide the best performance and savings for your home. In this article, we’ll look at the efficiency ratings you need to know, and why they matter.
HVAC efficiency ratings are standardized metrics that tell us how well a system uses energy. More energy-efficiency generally means more long-term savings on your electric bill. These ratings help us compare different models and make educated choices. The most common HVAC efficiency ratings to look for are SEER, EER, HSPF, and AFUE.
SEER ratio is calculated by dividing the total cooling output during a typical cooling season by the total electric energy input during the same period. The higher the SEER rating, the more efficient the unit.
EER is similar to SEER but measures the efficiency of a unit running consistently at a specific outdoor temperature (usually 95°F). Same as SEER, it’s the ratio of the cooling capacity to the power input. EER is particularly useful for comparing the efficienty of units in hot climates.
HSPF measures the efficiency of heat pumps. It’s calculated by dividing the total heating output during a typical heating season by the total electricity consumed. Like SEER, a higher HSPF rating indicates a more efficient system.
AFUE measures the efficiency of gas and oil-fired furnaces. A higher rating means more fuel has been converted into heat versus lost through exhaust. For example, an AFUE rating of 90% means 90% of the fuel is used for heating, while the remaining 10% is lost.
When choosing an HVAC system, it’s important to consider your local climate, energy costs, and specific heating and cooling needs. Investing in a high-efficiency system can mean big savings on utility bills and a smaller environmental impact.
HVAC efficiency ratings are key when deciding on the best HVAC system for your home. Comparing SEER, EER, HSPF, and AFUE ratings will help you get a system with the most performance and cost savings, while reducing environmental impact.
