Understanding SEER Ratings: A Guide for Homeowners
What SEER actually means, why it matters, and how to use it to make a smarter, more cost-effective cooling-system decision.
When it's time to upgrade your home's cooling system, you'll likely come across the term "SEER rating." While it might sound technical, understanding SEER ratings can help you make a smarter, more cost-effective decision for your Sioux Falls home.
What is SEER? SEER stands for Seasonal Energy Efficiency Ratio. It measures how efficiently a cooling system operates over an average cooling season — total cooling output divided by total electricity used. Higher SEER = lower bills.
Today's minimums. Modern systems start at SEER2 13.4 in our region. Premium units run SEER 18+ and pair with variable-speed compressors for steadier comfort and lower humidity.
Is upgrading worth it? If your current AC is 10+ years old and running below SEER 13, the energy savings from a modern unit usually pay back fast — especially when combined with utility rebates and our financing options.
