A SEER rating tells us so much more than just how efficient your HVAC system is running. It points out issues with your unit, reasons for rises in your energy bill, and more.
Here, we’ll talk a bit about the SEER rating, what it is, how it’s calculated, and why it matters.
Why Does SEER Matter for my HVAC System?
Having an HVAC system in good working order ensures comfort year-round. A high SEER rating is worth investing in.
How Does a SEER Rating Work?
Your HVAC system could have higher cooling efficiency in the late spring and early autumn compared to summer and winter. It works harder during hot and cold months and therefore takes longer to cool down, reducing efficiency.
What is a Good SEER Rating?
- Home size
- Type of ductwork
- Local climate
There’s nothing wrong with having a 14 rating if you live in a small one-bedroom apartment and don’t use AC or heat often. Similarly, it might be worthwhile to purchase a system with an 18 rating or above if you live in a large home and run the unit regularly.
Does the SEER Rating Change with Use?
Unfortunately, even the most efficient HVAC systems with SEER ratings of 14 and above will deplete over time. Efficiency depends on various factors, including:
- General wear and tear
- Regular maintenance
- Use of stock parts during repair
- Regular cleaning
When your HVAC system is damaged or filters get clogged, it works harder. When the system works harder, it takes longer to cool. This limits the overall efficiency, even if you have a unit that was once top of the line.
Locating Your HVAC SEER Rating
One of the questions we frequently get at Master Group HVAC is how to find the SEER rating on a unit. New systems come with an energy guide sticker. Usually, this is a yellow and black sticker with a SEER number.
Older machines or resale units might have the specs in another area. Whatever the case, the SEER rating resembles a product number. It might start with AC## followed by dashes and numbers. The number following XC is generally the SEER rating.
Replacement units might include the SEER rating on a building permit, sales slip, or other documentation. If you know the year, make and model of your unit, you can also contact the manufacturer directly.
