What you need to know about Heat pump efficiency ratings (SEER, EER, and HSPF)
You’ve probably seen SEER (Seasonal Energy Efficiency Rating) referenced when shopping for a heat pump efficiency. In fact, many companies will try to sell you a heat pump based solely on its SEER rating. While a good heat pump SEER rating makes a difference in how efficient the heat pump will perform at cooling your home, it will not give you much insight as to how it will perform in winter. But, there are other stats that tell THIS story.
We’ve put together some information to help you ask the right questions when you purchase a heat pump.
What is SEER, Anyway?
SEER explains the efficiency of the air conditioner (cooling) aspect of an HVAC system. It is nearly impossible to predict how much better a higher SEER rating system will perform (as typical usage is a vital part of that equation). However, a higher rating system will cool and dehumidify more efficiently than a lower grade machine.
EER – Energy Efficiency Rating
EER measures a systems cooling efficiency at a standard outdoor temperature (95 degrees). The formula utilized in measuring EER should show how much cooling power (BTU) is generated per hour or watt of energy. Comparing EERs on systems is a great way to predict performance.
HSPF – Heat Seasonal Performance Factor
Since SEER only measures performance during the cooling system, you need to look at a different performance factor to determine how your heater itself will perform. Look for this rating when comparing heaters to find out how efficient your system will be during the winter months. Realize that the results may show that those systems with the best SEER do not necessarily have the highest HSPF.
Once you understand what all the ratings entail, you can make a much smarter decision on your next heat pump purchase. If you have any questions or concerns regarding heat pumps, SEER, or HSPF, contact us at McCullough Heating and Air Conditioning. Our goal is to keep you comfortable all year round.
