If you are looking at buying a new air conditioner for your house, you may be confused as to what size air conditioner you should get for your house. There are a lot of choices out there and they can be really overwhelming. So how can you decide how big an AC you need and what should you keep in mind while you are looking for the best air conditioner to get?
When you are choosing what air conditioner you want to get, keep in mind that size matters. You may want to go with as big an air conditioner as you can so that your house will really get cold. However, you really don't want to do that. If you get the largest air conditioner you can, the air conditioner won't go through its full cycle, it will just quickly turn on, cool your house down, and then turn off really fast. The problem with that is that the heat from the summer is going to sneak back into your house and you are going to end up having to turn it on again. That will cost you more money. If you get an air conditioner that's too small, it will run continuously and have a hard time keeping up with your cooling needs. That will also cost you more money than you may want to pay. So you really need to make sure that you get just the right size.
You need to figure out the square footage of your house in order to get the right size air conditioner. That's because that's how the AC is rated. A certain amount of BTUs will cool a certain square footage. And in central air conditioners, BTUs are rated as tons. A ton equals 12,000 BTUs. In order to find the square footage of your house, you can just measure how long your house is by how wide your house is and then multiply those numbers. Then you can use an equation to figure out the right size air conditioner for your house. For example, if you have a 1,500 square foot house, then you are going to want to plug that into this equation:
- 1,500 X 25 = 37,500
- 37,500 / 12,000 = 3.1
- 3.1 – 0.5 = 2.6
So you'd need a 2.5 or a 3-ton sized central air conditioning unit.
Finding the right size air conditioning unit will make sure that your house stays at the optimal temperature and will mean that you aren't spending more money than you should.
