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 so important to find a system that provides quality comfort in your Cottonwood home while still being energy efficient. Higher energy efficiency means your system is operating well while using less energy. Whether you are looking into a replacement air conditioner or furnace or looking to upgrade your current equipment to be more energy efficient, there are some ratings to know that will help you during the process. 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, or rather, seasonally in Cottonwood . A higher SEER rating indicates a larger energy efficiency, which will turn into smaller utility bills. The Department of Energy requires a minimum 13 SEER-rating for cooler states in the north and a 14 SEER-rating minimum for humid, southern states. If your home has an mature unit with a lower SEER-rating, you could see drastic 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 measures the percentage of heat produced for every dollar of fuel expended. You can think of it as the MPG on your car. The greater the AFUE-rating, the smaller 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 misplaced through venting.

HSPF stands for the Heating Seasonal Performance Factor and operates to measure 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 productivity. Again, the larger the number, the more energy efficient the heat pump.
