Is Your Air Conditioner Obsolete?

SEER stands for “Seasonal Energy Efficiency Ratio” and it is meant as an indicator of how efficient your air conditioner is. Today’s air conditioners can range from 14.00 SEER all the way to 20 SEER.

Homes that are 10-15 years old usually have a system that ranges from 6.0 SEER to 10.00 SEER. Those “high efficiency” 10.00 SEER systems are now obsolete, and minimum SEER for systems produced since January, 2006 is 13.00 SEER! It’s a great idea to make sure you have a more modern working system within the acceptable SEER range because not only will it do a better job of cooling your home or business, but it will also save you potentially THOUSANDS OF DOLLARS. Air Systems is all about saving our customers money!

Plus the price of coolant for these older systems is expected to climb in the months and years to come. This is why it’s so important to maintain your AC system. Simple maintenance can keep you saving money and comfortable for years to come.
