Are you unsure on which unit you need for your home? When looking to purchase new systems be careful not to go too big or too small. If a unit that is too big, it will make the house cold and clammy in addition to starting and stopping the unit frequently causing the system to malfunction faster. A unit which is too small will always run and the home will never get to the desired temperature you'd like it to be.
So what size should I get?
There are a few different ways to size your area, follow the methods below for guidance.
