SEER refers to the Seasonal Energy Efficiency Ratio, which is a number used to measure overall energy efficiency for your heating or cooling unit. The government regulates SEER ratings, which vary by region. As a general rule of thumb, the higher your unit’s SEER rating, the more energy efficient it’s said to be, which is vital given Texas’ humidity. If you’re not sure what type of air conditioner or furnace best meets SEER requirements in the Frisco area, Air Masters’ experts would be happy to help!
