What Is a SEER Rating?

If you’re shopping for a new AC, you might feel confused by how many different units there are to choose from. One way to narrow down your choices is by looking for a unit with a higher SEER rating. But what is SEER rating? Think of it as an indicator of how efficient your heating and cooling system is—and the more efficient, the better.
If you’ve never heard of SEER ratings before, you aren’t alone. Lots of people aren’t familiar with the term. SEER stands for Seasonal Energy Efficiency Ratio. It’s calculated by dividing an AC unit’s total BTUs of cooling output during a given period of time by its total watt-hours of energy input during the same time period.
Fortunately, you don’t have to do complicated math to understand that a higher SEER rating means better AC unit efficiency. The concept is pretty simple. When your heating and cooling system runs … Read Full Post »
