What energy efficiency ratings mean and why they’re important

More than half of your utility bills in Dallas can be attributed to the cost to heat and cool your home. To save as much money as you can, you should find a system that can provide home comfort as efficiently as possible. The better your system’s energy efficiency, the more your system is doing while using less energy. If you’re preparing to upgrade or replace your HVAC equipment, you should understand a few terms and ratings to be fully informed and get the best energy efficiency possible.

SEER (used to measure cooling efficiency)
The Seasonal Energy Efficiency Ratio, or SEER, rating calculates the cooling efficiency of your equipment at different temperatures. Higher SEER ratings indicate better energy efficiency, and therefore, smaller utility bills. For chillier northern states, The Department of Energy requires a minimum 13 SEER rating. Warmer, southern states must a minimum SEER rating of 14. If your unit has a poor SEER-rating, an upgrade could bring you a beneficial spike in energy savings.

AFUE or HSPF (used to measure heating efficiency: gas or electric)
Annualized Fuel Utilization Efficiency (AFUE) ratio shows the percentage of heat produced for every dollar of fuel consumed—kind of like the miles per gallon you get from your car. Higher AFUE ratings translate into lower energy costs. So, an AFUE rating of 80 means that 80% of the heat produced by your furnace is heating your home, and 20% of the heat is wasted through venting.

The Heating Seasonal Performance Factor (HSPF) measures the heating efficiency of heat pumps. It is essentially the SEER rating for winter since it measures only heating efficiency. Like the other ratings, higher numbers mean better energy efficiency.
