For all your Heating and Air Conditioning Needs

If you’ve been shopping for an air conditioner, you’ve probably heard of a seasonal energy efficiency ratio. Put simply, the SEER rating is a measure of your air conditioner’s energy efficiency. Homeowners in McKinney, Texas, need to understand how SEER works in order to choose the right cooling option.

What Does SEER Mean?

In technical terms, a seasonal energy efficiency ratio is a coefficient of performance that measures the ratio between an air conditioner’s cooling output in British thermal units (BTU) and the energy it uses in watts (W) per hour. This is related to the energy efficiency ratio (EER), which is provided by the manufacturer.

But the SEER takes into account a range of outside temperatures to measure how the system will perform under real-time conditions. A higher SEER reflects better energy efficiency when the AC system is operating in your home.

What is a Good SEER?

Higher SEER ratings mean better energy efficiency. Here in Texas, the legally mandated minimum for any system installed after January 2015 is 14 SEER. However, there are many air conditioners that can exceed it.

For example, ductless air conditioners and heat pumps can reach 33 SEER. That’s thanks to their advanced technology and elimination of leaks in the duct system. Standard central air conditioners with ducts have maximum SEER ratings that are somewhat lower, in part because they lose some of their cooling power to duct leaks.

Geothermal or ground-source heat pumps can reach significantly higher efficiency ratings, up to 75 SEER in some models. However, the actual SEER tends to be slightly lower in our area because of the hot summer weather.
