Understanding SEER Ratings: A Key Factor in AC Efficiency

What is SEER and Why Does it Matter?

When it comes to air conditioning systems, one of the most important factors to consider is the SEER rating. SEER, which stands for Seasonal Energy Efficiency Ratio, is a crucial metric that helps determine the overall efficiency of your AC unit. At J. A. Sauer Heating & Air Conditioning, we believe in educating our customers about these technical details to help them make informed decisions.

Breaking Down SEER Ratings

SEER ratings typically range from 13 to 25, with higher numbers indicating greater efficiency. Here’s what you need to know:

  • 13-16 SEER: Standard efficiency
  • 17-20 SEER: High efficiency
  • 21+ SEER: Ultra-high efficiency

How SEER Affects Your Energy Bills

A higher SEER rating can lead to significant energy savings over time. For example, upgrading from a 13 SEER unit to an 18 SEER unit could potentially reduce your cooling costs by up to 30%. This is why J. A. Sauer always recommends considering higher SEER ratings when installing a new AC system.

Factors Influencing SEER Performance

It’s important to note that the actual efficiency of your AC system depends on various factors, including:

  • Proper installation
  • Regular maintenance
  • Home insulation
  • Climate conditions

This is why professional installation and routine servicing from experts like J. A. Sauer are crucial for maintaining optimal performance.


Understanding SEER ratings is just one aspect of choosing the right AC system for your home. As your trusted AC repair and installation provider, J. A. Sauer Heating & Air Conditioning is here to guide you through the process, ensuring you get the most efficient and cost-effective solution for your cooling needs.
