You may have heard about SEER, but do you really know what it is? The Air Conditioning experts at Northeast Florida Heating and Air can explain. The Seasonal Energy Efficiency Ratio, or SEER rating, measures your air conditioning system’s energy efficiency by calculating the cooling output divided by the amount of electric energy input. The higher the SEER rating, the greater the energy efficiency of your AC system. (It is important to note that the SEER rating average is calculated over a cooling season and is figured using a constant indoor temperature and a variety of outdoor temperatures, ranging from the 60’s to the 100’s, thus simulating a typical season.)
Why is your SEER rating important?
Your AC system has a white or yellow Energy Guide tag that lists the SEER rating of your unit. This rating lets you know how efficient your current system should be, or how efficient it will be after installation. The main purpose of a SEER rating is to help homeowners save money on their energy bills. Air conditioners have SEER ratings ranging from 6 to 25, but all modern AC systems are required to have a SEER rating of 13 or higher. The higher the SEER rating, the more efficient the system is and the more it will cost compared to a system with a lower SEER rating. The example below shows the average cost savings of an AC system with a 21 SEER rating:
$75/month x 12 months = $900 a year
$900/year x 15 years (typical life expectancy of an AC system) = $13,500 total savings
What is the best SEER value for my home?
As a general rule, a “good” SEER rating is at least 14 or 16, but there are certain variables to consider, such as:
- What square footage is your home?
- How hot does it get in the summer?
- How much shade is normally on your house?
- What color is your roof?
If you are purchasing a new AC system, the Comfort Consultants at Northeast Florida Heating and Air will determine the best SEER rating for your home and your budget based on these factors.
Are there other ways to improve HVAC efficiency?
Yes! Aside from investing in an air conditioner with a high SEER rating, there are other ways you can boost your system’s efficiency.
Schedule preventative maintenance. At least twice a year, call the highly trained technicians at Northeast Florida Heating and Air to do a maintenance check on your AC system. A well-maintained system will not suffer from blocked ductwork and filters, or other mechanical problems which can lead to reduced performance and higher energy costs.
Change air filters on a regular basis. This helps filter your indoor air and protects your system’s components against debris. Changing the filters about once a month is typical, but if you live in a home with pets or smokers, the filters should be changed more often.
Purchase a programmable thermostat. This will boost your system’s efficiency by adhering to a schedule designed specifically for you and your family. You can set the thermostat to different temperatures depending on the time of day, like when you are asleep, while at work, or when you are on vacation.
Seal and insulate the ducts that move air throughout your home. This prevents drafts coming from your attic, crawlspace, basement or garage, which can compromise the ventilation and temperature in your home. Your AC will have to work harder to combat the outside temperature so you can have the ideal climate inside your home.
