Are you in the market for a new air conditioner? If so, you may be wondering what you need to check out when making your buying decision. The following guide can help you pick out a new AC that is sure to cool your home efficiently during the summer.

#1: Your home's size

The square footage and layout of your home will effect the size of the AC unit you choose. The power and cooling output of an air conditioner is measured in BTU, Tonnage, and SEER units. BTU measures the power of the unit, while the SEER value measures the efficiency. Tonnage is used to measure cooling ability.

Every AC will be labeled with the measurements for these three units. Your AC professional will assess the square footage and layout of your home, then provide you with the size of AC you need to purchase to best cool your home. It's best to have this professionally assessed, since variables like how open your home is can affect the necessary tonnage you need to fully cool your home.

#2: Your ductwork

The existing network of ductwork in your home should be sufficient for any central AC unit that you are considering. However, issues may arise with the quality of the ductwork. Older duct systems can be full of leaks, which can compromise the efficiency and cooling ability of the ducts. Having the ducts inspected can help avoid problems when you install the new AC. This way, repairs, cleaning, or duct sealing can be completed. Otherwise, you may invest in a new AC only to find it still doesn't cool very well because the ducts need some maintenance.

#3: Unit types

Of course, not every house has existing ductwork. If you didn't previously have central AC or a forced-air furnace, there may be no ducts within your home. In this case, you have two options: choose an AC system that doesn't require ducts, or have ductwork installed. The second option is the most difficult and the most expensive, especially in homes that do not have crawlspaces or basements. Fortunately, there are ductless AC options. Window units are a common, albeit loud and unsightly, option. A better option may be to have a mini-split AC installed. These are a cost-effective, ductless solution that only requires that a small hole is drilled into the ceiling of each room where an air exchanger will be placed.
