SEER is “Seasonal Energy Efficiency Ratio.” It’s a number derived by dividing your AC (air conditioning) unit’s BTUs (British Thermal Units)* by the amount of electrical wattage used. Therefore, the higher the SEER rating, the higher your air conditioning efficiency.

If you have an older air conditioning system, you may have a SEER rating as low as ten.

Today’s AC systems have SEER ratings as high as 23! In fact, the government requires central AC units have a 14 or greater SEER rating.

Calculate Your Costs

Texas residents need efficient air conditioning systems. Our heat index – and our electric bills – can be staggering in the summertime! A SEER calculator can help you determine approximately how much you’re currently spending on cool air.

SEER Calculating

Benefits of Upgrading to a Higher SEER A/C UnitYou need to know your unit’s tonnage and SEER rating, and if you can’t figure it out, take a picture of your HVAC (heating, ventilation, air conditioning) unit’s label, then call us (281-651-5484, 936-271-2030). If possible, we will help you determine both. The other number you need is the SEER rating you want (23, of course).

Based on the SEER calculator developed by our neighbors in Florida, if you have an AC unit that has a 3 tonnage with a SEER rating of 13, your current electricity costs are about $1,018/year. If you upgrade to a unit with a SEER rating of 22, you’ll save 41% in energy costs/year. Your new AC system will use about $602/year in electricity. With 13 SEER vs. 22 SEER, you’ll save approximately $2,082 within a 5-year period, $4,164 in ten years, and $6,247 within 10 years.

Size Matters

While your potential for a higher energy efficiency is greater with a higher SEER rating, don’t forget another important factor: Your HVAC system should also be sized to fit your home or business. In fact, over half your system’s efficiency depends on correct equipment sizing and proper HVAC installation.

*BTUs are the international measure of energy. They measure the amount of heat an air conditioning unit can remove from a room/space.
