Central air conditioning is a popular way to enhance your home. Air conditioning keeps you cool in the summer, controls humidity and can help reduce allergies.

The Seasonal Energy Efficiency Rating, or SEER, tells how efficient your A/C will be on a typical hot summer day. The higher the SEER, the more efficient the system. Focus recommends buying a unit that has a SEER of 15 or higher to get the most out of your cooling dollar.

Remember that getting the proper size and a quality installation is essential to getting the most from your new equipment. When replacing HVAC equipment, bigger doesn't always mean better. Oversized equipment will cost more to install, create more wear and tear due to frequent cycling, and may not properly remove humidity from the air — resulting in an uncomfortable home.

A correctly-sized air conditioner matches cooling power to the characteristics of your home. Ask your contractor to do a load calculation that takes proper account of your home’s size, window area, insulation levels, existing ductwork, and other factors.
