Cooling System FAQs

What is a SEER? 

There are special names for the efficiency ratings of various types of equipment.  Air conditioning equipment is rated by the Seasonal Energy Efficiency Rating or SEER.  The higher the SEER, the more efficient the unit.  

What size air conditioner do I need? 

As a general rule, you will want an air conditioner that is ideally sized for your building so that it is not running over capacity or sitting idle for too long. A quick method you can use to estimate the ideal size is to take your square footage and divide it by 400. Typically, the average home needs 1 ton for every 400 sq ft of living space that will be cooled. So, if your home is 1,200 sq ft, you will require a 3-ton air conditioner.
