What energy efficiency ratings mean and why they’re important

More than half of your utility bills in Thousand Oaks are comprised of the cost to heat and cool your home. To save as much money as you can, you should look for a system that can supply 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 measures the cooling efficiency of your equipment at varying temperatures. Higher SEER ratings denote better energy efficiency, and therefore, more affordable utility bills. For cooler northern states, The Department of Energy requires a minimum 13 SEER rating. Warmer, southern states must must have a SEER rating of 14 or higher. If your unit has a lower SEER-rating, an upgrade could bring you a helpful 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 expended—kind of like the miles per gallon you get from your car. Higher AFUE ratings equate to lower energy costs. So, an AFUE rating of 80 means that 80% of the heat generated by your furnace is heating your home, and 20% of the heat is lost through venting.

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