What energy efficiency ratings mean and why theyre 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 look for a system that provides excellent comfort in your McMurray home while still remaining energy efficient. Greater energy efficiency means your system is operating well while using less energy. Whether you are thinking about a replacement air conditioner or furnace or looking to upgrade your existing equipment to be more energy efficient, there are some ratings to know that will help you during the search. So what exactly do those energy efficiency ratings indicate?

SEER (used to measure cooling efficiency)
SEER stands for Seasonal Energy Efficiency Ratio. The SEER rating reflects the competence of your unit at different temperatures, meaning, seasonally in McMurray. A greater SEER rating denotes a higher energy efficiency, which will translate into smaller utility bills. The Department of Energy demands a minimum 13 SEER-rating for cooler states in the north and a 14 SEER-rating minimum for hotter, southern states. If your home has an aged 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 finds the percentage of heat generated for every dollar of fuel expended. You can consider 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 produced is exhausted to heat the home, while 20% of the heat is wasted through venting.

HSPF stands for the Heating Seasonal Performance Factor and is used to keep track of the heating effectiveness of heat pumps. It is the SEER rating for the colder months as it only measures your unit’s heating efficiency. Like the others, the higher the number, the extra energy efficient the heat pump.
