What does SEER mean for an HVAC system?

The SEER of your HVAC system is something you will become very familiar with when planning to replace your residential HVAC system in Maitland FL. Let’s look at what SEER means, what SEER options are there, and what SEER is best for you.


SEER stands for Seasonal Energy efficiency Rating. In fancy terms, it is the ratio of the cooling output of an air conditioner over a typical cooling season, divided by the energy it uses in Watt-Hours, also known as Seasonal Energy Efficiency Rating.

In SIMPLE terms, the SEER determines the energy efficiency of your HVAC system when cooling your home.  The SEER is the MAXIMUM efficiency rating, so just like in your car when you see your average MPG on the highway, the SEER can be low depending on different situations.  

What are the SEER options available today? 

The SEER ratings currently range from 13 SEERS to 21 SEERS. The HIGHER the SEER the more efficient your HVAC system will be. The minimum SEER in residential HVAC systems in Florida is 14 SEERS. That means that when you’re shopping for a new HVAC system the most budget friendly option will be a 14 SEER, which will also have the lowest energy efficiency. The higher the SEER, the more expensive the equipment becomes. 

Which SEER should you choose 

There a few things to consider: What is your budget? How often do you run your A/C? Are you looking to spend more now and save on energy efficiency over time?
