What Does the SEER Efficiency Rating for HVAC Equipment Mean?



Hudson, NH Homeowner Has Questions

The energy efficiency of air conditioning systems is measured by SEER (seasonal energy efficiency ratio) and EER (energy efficiency ratio). The higher these ratings, the lower the operating costs. SEER refers to the electrical input that is required to run the air conditioner during a typical season, divided by the energy that it uses. An EER rating is typically used to measure smaller, room air conditioners and is based on the operating costs of the air conditioner with an outside temperature of 95 degrees.

After suffering through the sweltering summer months, a Hudson homeowner had decided to install central air conditioning in his home. Wanting to install an energy efficient system, he contacted the experts at Joyce Cooling & Heating.

For Energy Efficiency, Look at the AC Unit’s SEER Rating

The SEER rating determines how energy efficient an air conditioning unit is by comparing the cooling output in a typical season to the energy it uses in watt-hours. This calculation is done using a designated indoor temperature and a range of outdoor temps from 60 to 100 degrees to simulate a typical cooling season.

A higher SEER rating means that the system is more energy efficient. The range of SEER ratings for air conditioning units is between 13 and 21. Those units that have a higher SEER rating do cost more and often include a 2-stage or variable-speed compressor and a variable-speed blower. Units with lower SEER ratings often frequently have one run speed.

While the initial cost of a unit with a higher SEER rating is more, the energy savings over time can make it well worth the investment. The homeowner in Hudson opted for a variable-speed unit with a high SEER rating. This will make a significant difference in his utility bills in the summers ahead, as he enjoys a more efficient system.


Testimonials & Reviews

We had central air conditioning installed last year by Joyce and were very satisfied with the job. Today, John N. serviced the unit and all of the components and he was incredibly thorough and professional. He explained exactly what was serviced and what to avoid (greenery around the outdoor unit). I highly recommend Joyce Cooling & Heating!
