Guide to SEER Ratings
Developed by the U.S. Department of Energy to give an apples-to-apples comparison figure between air conditioners made by different manufacturers, SEER ratings are determined by dividing the amount of cooling (in BTUs) a unit provides by the amount of energy it takes to achieve those BTUs under set environmental conditions.
However, conditions in a lab don’t come close to approximating real-world conditions, so AC Unit installers need to be well-versed on calibrating your system to make sure it’s functioning at its highest efficiency specific to your home.
Modern-day home air conditioning units generally fall on a scale between 13 and 16, though some AC units grade as high as 23. The higher the number, the more efficiently it will cool. The current minimum is a SEER rating of 13, but some older units may only function to a level of 5 or 6. In our Phoenix heat, it’s recommended that homes have at least SEER 16.
Highly rated units will cost more on the front end, but homeowners will see the savings on their bill each month and will make up the cost of a new, high efficiency unit in the long run. Depending on how efficient your new unit runs, you may also be eligible for rebates locally and tax credits at the federal level.

Precision Air & Heating is truly a reputable company and certainly number one for service in my book. Shawn, the repair manager was extremely helpful and professional. I would recommend them for both installation of a new system as well as repairs on your existing AC.
We were visiting our Arizona home from New York, when on one of the hottest days in August the air conditioning was not working. We called Precision & James Shelton worked to get the air up & running in no time. He was courteous & sympathetic, working hard to repair our central air…we have a warranty & Precision stands behind their work, they are available 24/7… Thank you!
Service was completed in a timely manner and my technician was extremely knowledgeable. All services were explained to me prior to being completed as far as the need and cost are concerned. My air conditioning unit has been problem-free all year and I believe it’s because of the professional maintenance that I get yearly from Precision Air.
