2 Mistakes To Avoid When Sizing Your Home's New Central Air Conditioning Unit

After your home's central air conditioner broke down, you are in the market for buying a new one. However, with so many sizes available, you may be having problems choosing the correct size for your home. While making your selection, make sure you do not make either of the mistakes below when sizing your new AC unit.

1.  Selecting an AC Unit That Is Too Small for Your House

If your air conditioner broke down suddenly in the middle of a heat wave, you may not have a whole lot of money set aside. Because of this shortage of funds, you may be tempted to opt for a smaller central AC unit.

However, while you may save money in the beginning by buying a smaller air conditioner, doing so may wind up costing you in the long run. Since a unit that is too small for your house will have to work harder and more often to keep the space cool, you will see a dramatic increase in your energy bills.

Also, since the unit will be running most of the time, it will wear out faster. This means that you may end up having to buy a new one well before its expected lifespan.

2.  Choosing an Air Conditioner That Is Too Big

After finding out that you should not buy an air conditioner that is too small for your home, you may decide that you should purchase the largest unit that you can afford. After all, since the unit is bigger than your current one, it should keep your house cold and comfortable without having to run constantly, right?

While this may seem logical, having an AC unit that is too big could have the opposite effect. Because the unit will blow more intense cold air through itself, the unit will wind up making itself too cold. It may then start to freeze up on a regular basis.

This would then cause the compressor to not be able to adequately function, and the air will stall inside the unit. You will then have a warm house and need to thaw out the unit constantly.

When trying to determine which air conditioner you should purchase for your home, size matters a lot. If you are having problems determining which size you should buy, speak with a contractor who offers air conditioner installation services so that they can help you pick the right one for your home's space.
