What is a SEER Rating?

SEER stands for seasonal energy efficiency ratio. SEER is an HVAC term used to describe the efficiency of an air conditioner. The efficiency of an AC unit is determined by the Air Conditioning, Heating, and Refrigeration Institute (AHRI). The higher the SEER rating of an air conditioner, the less electricity it will consume.

Remember that the AHRI determines the SEER rating in a controlled environment and under perfect conditions. Unfortunately, the attics in South Florida are less than ideal, and the heat is extreme, so choosing an AC company that knows and follows the manufacturer’s AC design and installation specifications is essential.

If you’re about to purchase a new air conditioner and are concerned about how much energy you’re using and spending every month, then the SEER rating is something to consider. 

If your current AC is older than ten years old, your SEER rating is probably 11 or less, which means your AC is working hard to cool your home, and you’re spending more money on your utility bill than you need to. If this is the case, you will want to replace your air conditioner before summer.

Where is Your AC’s Seer Rating Located?

You may be wondering what the SEER rating of your current AC is. Your air conditioner should have the SEER rating on a sticker that says Energy Guide or the AC’s serial number. The manufacturer will list the SEER rating with a number and a c ex. 9c.

Why You Should Hire an ECM AC Technician to Install Your AC

The way your AC is installed is critical to the performance and longevity of your AC. For example, you may have a new air conditioner with a SEER rating of 20 or higher, but if it isn’t installed properly, it will perform more like an AC with a SEER rating of 11.

Over 50% of air conditioners installed today are installed wrong with an average 30% loss of efficiency. Unfortunately, most AC companies never address this. East Coast Mechanical’s (ECM) AC technicians are trained to engineer, install and design an air conditioner per the manufacturer’s requirements and specifications to achieve the level of efficiency the manufacturer intended for your AC unit.

ECM’s AC system design technicians start with a 99-point home survey to determine any air leaks, measure the ductwork for airflow capacity, identify any hot rooms and figure out the best location for your new air conditioner.

We will educate you on your current AC system, inform you about your AC options and explain any issues you may have with your current system or ductwork. For example, most homes today have undersized ductwork, restricting the needed airflow to achieve the rated SEER and efficiency. 

If this is the case, our technician will make the needed modifications to your existing ductwork, improving airflow distribution throughout your home.

If you upgrade your AC unit from a 9 to a 16, your energy consumption will decrease by about 30%. This could amount to as much as a $300 savings per year. ECM AC technicians recommend getting an AC with at least a 16 SEER rating. 

At ECM, we will design the perfect system for your home while correcting any deficiency that would adversely affect your new AC systems SEER rating. At ECM, your total comfort and satisfaction guaranteed or your money back.

SEER Rating: The Importance of AC Maintenance (AC Tune-Ups)

Your SEER rating can change depending on how you take care of your air conditioner. If you don’t get regular maintenance for your AC, the overall efficiency will decrease by about 5 % per year. ECM AC technicians recommend getting two AC Tune-Ups annually to ensure your AC works efficiently and your SEER rating remains intact. 

The SEER rating will drop as the efficiency of your air conditioner drops.
