What energy efficiency ratings mean and why they're important

January 10, 2017

The cost to heat and cool your home totals more than half of your utility bills. That’s why it’s crucial to search for a system that offers quality comfort in your Lodi home while still remaining energy efficient. Better energy efficiency means your system is working well while using less energy. Whether you are thinking about a replacement air conditioner or furnace or considering to upgrade your existing equipment to be more energy efficient, there are some ratings to look out for that will help you during the procedure. So what exactly do those energy efficiency ratings mean?

SEER (used to measure cooling efficiency)
SEER stands for Seasonal Energy Efficiency Ratio. The SEER rating reflects the efficiency of your unit at different temperatures, in other words, seasonally in Lodi. A larger SEER rating indicates a larger energy efficiency, which will convert into less expensive utility bills. The Department of Energy requires a minimum 13 SEER-rating for colder states in the north and a 14 SEER-rating minimum for humid, southern states. If your home has an older unit with a lower SEER-rating, you could see radical energy savings after an modern system.

AFUE or HSPF (used to measure heating efficiency: gas or electric)
AFUE stands for Annualized Fuel Utilization Efficiency ratio and it keeps track of the percentage of heat created for every dollar of fuel consumed. You can consider it as the MPG on your car. The higher the AFUE-rating, the less your energy costs. If your furnace has a AFUE rating of 80, that denotes that 80% of the heat generated is consumed to heat the home, while 20% of the heat is lost through venting.

HSPF stands for the Heating Seasonal Performance Factor and works to determine the heating efficiency of heat pumps. It is the SEER rating for the winter season as it only keeps track of your unit’s heating effectiveness. Again, the larger the number, the more energy efficient the heat pump.
