BlogJuly 23, 2021Are ENERGY STAR air conditioners worth it?

First, let’s answer the question “what is an ENERGY STAR air conditioner?” Air conditioners awarded the ENERGY STAR certification meet strict energy efficiency guidelines set and tested by the U.S. Environmental Protection Agency (EPA). Read more about what it takes to achieve the ENERGY STAR certification here.

According to, “ENERGY STAR certified central air conditioners and air-source heat pumps have higher seasonal energy efficiency ratio (SEER) and energy efficiency ratio (EER) ratings and use 8 percent less energy than conventional new models.”

The Seasonal Energy Efficiency Ratio (SEER) rate of an ENERGY STAR HVAC unit will range from 13 to 23. The higher the rating, the more efficient the device is at regulating energy and saving money. But is it worth paying more for an ENERGY STAR rated unit?


Air conditioners with the ENERGY STAR certification tend to cost more than those units not certified. However, all ENERGY STAR units boast greater SEER ratings and consume as much as 30 percent less energy on average than ordinary air conditioners. They not only help you save money long term, but also perform better, cooling your home in a matter of minutes.

For example, the Trane TruComfort TRANE XV18I Series paired with the TAM9 23,600 BTU capacity unit has a 19.5 SEER, costs $111 annually to operate, and provides a savings of 33% over a model that just meets the federal minimum standard.*

The US Department of Energy has made it mandatory for air conditioners to carry a minimum SEER of 14 in states like Florida with warm weather all year round. ENERGY STAR air conditioners meet this criterion easily. The same cannot be said for low-cost uncertified units.

One more reason to consider an ENERGY STAR rated system: less energy used equals a better environment for future generations.

ENERGY STAR even has a checklist to help you determine when it’s time to replace your air conditioner.

So which AC unit is the most energy efficient for your home?
