Understanding SEER Ratings: A Key Factor in AC Efficiency

Global warming is having a profound impact on the climate in Winnipeg. This December, Winnipeg residents enjoyed spring-like temperatures. New warm temperature records were set in the province.


The implications of global warming are hotter summers and record-breaking temperatures. With these higher temperatures, Canadians will rely on their air conditioners more than ever before.


It is essential that you invest in an efficient air conditioner that does not run your electricity bill through the roof. Read on to learn about the key factors for AC unit efficiency. Explore topics such as SEER ratings and why you should consider them when buying an AC unit.


What Is a SEER Rating?


SEER is short for seasonal energy efficiency ratio. This simple ratio takes the cooling output of an AC unit and divides it by the total energy used. It is essentially an AC efficiency rating that tells consumers how well their unit cools the home.


A SEER rating is calculated over the average cooling season. It would not be practical to include data from colder months when the AC is not in use.


The less energy and money you need to fuel your AC, the higher the SEER rating will be. It is important to note that an AC unit's SEER rating reflects its maximum efficiency.


What Is Energy Star?


Energy Star is another certification that is associated with major appliances like air conditioners. You may see the Energy Star logo on your AC unit.


In Canada, an Energy Star-qualified unit uses 20% less energy than a standard air conditioner. Energy Star certification also partially depends on the unit's SEER rating.


For a single-package unit, a 12.0 SEER rating is necessary to obtain Energy Star certification. For a split system, the SEER rating requirement increases to 13.0.


Not only does Energy Star have a reputation for using less energy, but it also produces tangible benefits for the environment. Energy Star units reduce greenhouse gas emissions and smog precursors.


Does the SEER Rating Decrease Over Time?


An air conditioner's SEER rating does not change over time. It is calculated for the make and model's maximum efficiency at the time of manufacture.


However, an AC unit's efficiency can decline over time without proper preventative maintenance. For example, if you do not change the AC unit's air filter, the unit will gradually become inefficient. The clogged filter prevents airflow, and it will take longer for your home to reach the desired temperature.


Your air conditioner requires other preventative maintenance to remain efficient. The best tactic is to hire a professional HVAC technician to service your air conditioner on an annual basis.
