Good SEER Rating For An AC

The SEER rating, also known as Seasonal Energy Efficiency Rating, is one element to consider when choosing an HVAC system. Remember that you should know what SEER stands for and what a good SEER is when looking for air conditioning replacement Cobourg. This is the ratio of an air conditioner’s cooling output divided by its energy in Watt-Hours over a typical cooling season.

A SEER ratio is determined throughout a cooling season using a constant indoor temperature and a range of external temperatures between 60 and 100 degrees Fahrenheit. Remember that the SEER ratio is a maximum efficiency number, similar to your car’s fuel efficiency.

Let’s say your automobile gets on the highway. However, if you’re stopped in traffic in a city, it’s a lot less efficient. Your air conditioner is in the same boat. If your SEER ratio is 21, that is the maximum efficiency; however, depending on the circumstances, it may be lower.

What is a Good SEER Rating?

The SEER rating is directly proportional to the efficiency of the unit. The rating is a representation of the HVAC unit’s maximum efficiency. New units must have a minimum rating of 13, with the majority falling between 13 and 21; however, some models may go higher. Older models or of poorer quality may receive a lower grade. The SEER rating of most builder-grade HVAC units is 8 or 9.

When buying an energy-efficient air conditioner, SEER ratings are the most important factor to consider. It’s vital to understand a decent SEER rating for an air conditioner. Choosing the 18 or 20 SEER air conditioner over the 14 SEER air conditioner will save you more than $50 a year. That’s around $500 in ten years. For example, ductless mini-split ACs with SEER ratings above 20 are available.

Benefits of a High SEER Rating


Higher Energy Efficiency

A higher SEER number means more energy efficiency. The SEER rating of 13 does not always imply that a unit is inefficient. Most older air conditioners have a SEER rating of 8 or 9, so even the cheapest SEER-rated system on the market today can save you money.

Improved Indoor Comfort

You will be more comfortable in the summer months if you choose an air conditioning that has a two stage compressor. Single-stage air conditioners with lower SEER ratings usually only have one speed. This means they’ll turn on and off frequently during warm weather, causing uneven cooling or hot and cold places.

You’ll also notice increased humidity, making it feel more desirable than it is. To eliminate humidity from your home’s air, your A/C must operate for a longer duration. Regular AC service is essential to maintain indoor comfort.
