What is SEER rating?
SEER is a rating system that explains in smaller numbers how efficient that system is. The US Department of Energy has mandated that air conditioners meet minimum efficiency ratings, and thus, the energy guide was born.
What does higher SEER rating mean?
Higher SEER ratings mean more efficient machines and a lower annual cost of operation. Purchasing an air conditioner based on SEER values alone is not recommended. However, it is a great indication of potential savings, model and operational costs, and gives you a place to start your budgeting. Author.
How to calculate SEER rating?
How to Calculate Your AC’s SEER Rating 1 . Essentially a SEER rating is the numerical ratio of watts input and BTU output. So your first step is to find the BTU output of the device. You can use exact numbers if they are known, or use the numbers based on air conditioner tonnage (see further below). 2 . Next, find the watts used per hour of your air conditioner. This can be found on the documentation, information plate, or on the brand’s website. If the wattage is not listed, multiply the voltage and amps together to get the watts. 3 . SEER is a seasonal number, and for air conditioners, that season is summer. Therefore you need to determine how many days of summer you are calculating for. Most SEER ratings use 125 days, but colder climates and northern regions may go as low as 90. 4 . Now you need to calculate the watt-hours (wH) used by your machine. Simply take the watts from above and multiply by 1000. The result will be the number needed for the ratio. 5 . Next, calculate the BTU-hours for the ratio by multiplying the BTU output from above by the number of summer hours you are calculating for (1000 for 125 days at 8 hours per day, or 720 for 90 days). 6 . Finally, divide the BTU hours by the watt-hours to get your SEER rating estimate.
Why do air conditioners need variable speed fans?
Larger capacity air conditioners need variable speed fans and compressors to keep the refrigerant moving and removing heat. This also translates into more humidity being removed. High SEER units have multi-speed fans and compressors, allowing them to take a larger role in humidity control.
How does using less electricity help the environment?
While it may not be a direct correlation, over time, higher SEER appliances, air conditioners, and other systems will reduce carbon emissions , require less energy and take a major strain off existing networks and systems.
Why do compressors and fans have a drop in noise?
Because technology requires that SEER values keep going up, more efficient systems are being built each day. This means a massive drop in noise levels, too. Since compressors and fans now operate on multi-speed and variable speed technologies, they don’t produce as much noise. Some brands see a drop of over 20dB with higher SEER units compared to their lower SEER counterparts.
What does SEER mean in HVAC?

Comparing Seer Ratings
SEER stands for Seasonal Energy Efficiency Ratio. The higher the SEER rating the more efficient the unit will run, thus leading to lower energy bills. If you compare a 10 SEER AC unit to a 20 SEER AC system, the 20 SEER system will provide twice the efficiency.
A Specific Example
If you are running an older 10 SEER, 5-ton model and it is operating at good-to-peak efficiency, your yearly cost of operation will be approximately $1,316.00 per year. Replacing this unit with a 20 SEER-rated system can bring that cost down by as much as 50% or $658.00 per year (SEER Savings, 2019).
How Do These Changes Make a Difference in Efficiency and Comfort?
The standard 14 SEER system is either on or off. This means the fan and compressor are running at high speed the entire time it’s cooling your home. The two-stage compressor runs at two speeds, low and high. When the system comes on it automatically starts in low gear and runs very efficiently until it can’t keep up with the load.
