In an ever expanding effort to continue to educate the homeowners of the Philadelphia area, Fahrenheit HVAC is debuting a new blog series that will focus on breaking down technical terms in the HVAC industry. This series will enable homeowners to be more confident when speaking with service professional, while also helping you from becoming the victim of scam simply because you did not know the right lingo! Check back frequently as we continuously update our blog with terms that we hear the most confusion about from our customers.

What does SEER mean?

The first term that we are tackling in our HVAC Word of the Day series is SEER. SEER is actually an acronym standing for Seasonal Energy Efficiency Rating. The Seasonal Energy Efficiency Ratio, or SEER, is a ratio of the cooling output delivered by a central air conditioning system divided by the amount of energy which was used to create this output.

Simply put, a higher SEER rating means that your system is producing more output while using less energy. This would translate into a lower energy bill, since less energy is being used to achieve the same level of home comfort. This is why energy providers, like PECO, offer their customers rebates for switching to more energy efficient appliances.

What is a good Seasonal Energy Efficiency Ratio?

It is important to remember, that SEER is a variable number and changes based on any outside variable which may be occurring. To easily understand this, think of SEER as the mile-per-gallon of your vehicle. If you drive on the highway consistently, your vehicle will get better MPG than city drivers, due to the outside variable of stop signs.

Similarly, a Seasonal Energy Efficiency Ratio is the maximum efficiency which the unit can achieve, however; this does not mean the air conditioning unit is constantly operating at that level of efficiency. If you system is constantly changing temperatures, the effective SEER would be lower than that of the same system which dealt with more consistent temperatures.

Top Three SEER Meaning Takeaways

SEER is a variable number
Higher the SEER the more efficient the system potentially could be
More efficiency is achieved with consistent temperatures

Now that homeowners have a better understanding of SEER, it may be easier to make a decision on installing a new air conditioning system. While you typically do want a higher SEER, keep in mind that the rating is variable and depends on outside factors at your home. Speak with a professional about the HVAC use in your home and they will be able to provide a clear picture of the system which would be best for your home.
