What is a SEER rating?

A S.E.E.R. (Seasonal Energy Efficiency Rating) is the rating and performance standards that have been developed by the U.S. government and equipment manufacturer’s to produce an energy consumption rating that is easy to understand by consumers. It has a universal formula and conditioning that can be applied to all units and compensates for varying weather conditions.

Basically, the lower the S.E.E.R. rating, the more energy (electricity) is required to produce the desired effect.

EXAMPLE:
S.E.E.R. OF “6”
(6 is a very common rating for older units produced prior to the 1990’s, when energy was relatively inexpensive)
Produces about 6 BTU/hr of cooling, per watt of electricity

S.E.E.R. OF “13” (13 is now the minimum required efficiency for systems installed in the US)
Produces about 13 BTU/hr of cooling per watt of electricity
This would be more than double the cooling effect of a 6 S.E.E.R. unit

This increased efficiency has become more and more important as electricity rates continue to rise.

How often should I change my filters?

First, let me say it is very important that you do change your filter regularly.  It helps extend the life of your system and helps to keep it running at it’s most effcient level.  How often you change your filter really depends on the type of filter you have and the amount of particulates in your home.  Things like pet dander, smoking, and living on a dirt road can increase how often you need to replace your filter.  For most people with a standard 1″ filter, the best thing to do is to change your filter every 30 days.  Some systems are equipped with more advanced filtration systems and my only require a filter replacement once  a year.  If you don’t know what you have, check with your local heating and cooling company, they can check your system and advise you how often your filter needs replaced.
