Energy ratings provide essential information about your HVAC systems. The better your energy rating, the less you’ll spend heating and cooling your home. Check for these key numbers on your heating and cooling products to see how eco-friendly your system and to cut costs. You should always look for a better rating if you’re upgrading to a new system for your Maplewood, Missouri, home.


Your seasonal energy efficiency ratio (SEER) determines the cooling efficiency for your air conditioner. The SEER is determined over a period of several months to give you an idea of how your system will perform on average over the course of the year.

Typical SEER ratings are between 13 and 23. The higher your SEER, the less you’ll spend on energy with your cooling system. But higher isn’t always better. A professional can help you determine the best SEER for your home’s cooling needs and your budget.


The energy efficiency ratio (EER) is similar to the SEER, but it’s based on a single set of conditions. This makes the EER slightly less accurate. However, this is a good indicator of how a system performs in more extreme conditions. To qualify as an ENERGY STAR system, an HVAC product must have an EER of 11 if it’s a single model or 12 if it’s a split system.


The heating seasonal performance factor (HSPF) is an energy rating used to evaluate heat pumps in heating mode. Split system heat pumps must have an HSPF of 8.2 or higher. Single package units must have an HSPF no lower than 8.


The annual fuel utilization efficiency (AFUE) for a furnace determines how much heat it produces for each dollar of fuel you consume. The higher your AFUE, the less you’ll spend on heating fuel.

Standard furnaces must have an AFUE of 78 percent or higher. Those in mobile homes must have an AFUE of at least 75 percent.

When you’re looking for a new HVAC system, these ratings are key indicators of how much you’ll spend on long-term operating costs. Averill Heating & Air Conditioning can help you find the best model for your home. Give us a call today at (314) 427-3825.
