A too small-sized AC unit can be an issue as well. It runs too hard to cool the house down, and at the end, you will face energy bills. The right-size AC unit cools the house properly, and it takes away the humidity at the same time.

Do the math

First, you should know the entire square footage of your house that you want to cool by multiplying the length and the width. After finding out it, next, you should multiply it by 25 BTUs. The result will help you to find the required capacity.

You can increase or decrease BTU capacity depending on the place that you want to install the AC unit system. If the location is heavily shaded, reduce 10 percent of BTU capacity. If it is sunny, increase it by 10 percent. Also if more than two people usually spend time in the room, you need to add an extra 600 BTU per each person. If you want to install the air conditioner in your kitchen, you should consider that kitchens produce a lot of heat. That’s why you should add extra 4000 BTU to your result.

Troubleshoot repairs yourself


When your air conditioner breaks during the summer, you should wait for an HVAC specialist to fix and you will pay at least hundreds of dollars in AC repair costs. If you are good enough to work around electricity and do not want to spend extra money, you can repair your AC unit for around two hours and save a lot of money on parts and labor.
