When shopping for a new HVAC system, one term you’ll encounter often is SEER rating. But what is it, and why does it matter—especially if you live in Texas?
At Tarrant Mechanical, we believe informed homeowners make smarter decisions. That’s why we’re breaking down the SEER rating—what it means, how it affects energy efficiency, and how to choose the best HVAC system for your Texas home.
SEER stands for Seasonal Energy Efficiency Ratio. It measures the cooling output of an HVAC system during a typical cooling season divided by the energy it consumes in watt-hours.
In simple terms:
The higher the SEER rating, the more energy-efficient the HVAC system.
A higher SEER rating means your HVAC system uses less electricity to cool your home. This leads to lower monthly utility costs—especially during the brutal Texas summer months.
Energy-efficient systems with higher SEER ratings consume less power, reducing your carbon footprint and contributing to a greener home.
Systems with high SEER ratings often include variable-speed motors and smart features, which result in:
Not necessarily.
While a system with a SEER 21+ rating is extremely efficient, it also comes with a higher upfront cost. The right choice depends on:
At Tarrant Mechanical, we help you calculate the payback period so you can determine whether the long-term savings justify the investment.
As of 2023, manufacturers have also started using SEER2, a more accurate test that reflects real-world conditions. SEER2 ratings tend to be slightly lower than SEER ratings for the same equipment, but they offer a better comparison of true performance.
If you’re shopping for a new HVAC system in 2025 and beyond, make sure you understand whether you’re looking at SEER or SEER2 ratings—and what the minimums are in your region.
