What Size Air Conditioner Do I Need? - Ask the Expert Episode 102

In this episode, Dan Danowski explains why it is important to pick the right size air conditioner for your house.

Video Script:

Steve in Norman, Oklahoma asks, "Hey Dan, how do I know what size air conditioner I need for my house?"

That's a good question, and the answer is you need the Goldilocks one. What do I mean by that? You want an air conditioner that's not too big and not too small. You want one that's just right for your house. You might think, "Oh, well I could just get a really big air conditioner and it will be fine!" No, it won't there Bucko! It could be really bad.

You get too big of an air conditioner, you're going to get short cycling. That will make your house feel clammy and crappy. What happens in short cycling is you have an oversized air conditioner, it comes on and it's really strong, and then it gets the temperature where you want it really fast and then it shuts off. You might think, "that's good, right?" No! That's bad! It's going to cause increased mechanical failure. It's not going to last the 15 years it's supposed to, Steve.

The start up and the stop is where the most stress happens. The more that happens, which will be the case if you have an oversized air conditioner, you're going to see a breakdown earlier. That could cost you a lot of money.

Too small an air conditioner? The problem is obvious. Your house isn't going to get cool enough.

You need to get a manual J load calculation done on your house by a qualified service technician, someone like me, but don't call me because I'm not in Norman, Oklahoma. Then, you buy the size you need and everything's great.

Point being, you get that done, you get the right sized unit, you're going to get great heating and air, it's going to last a long time and you're going to be very happy and you're not going to get eaten by a grizzly like Goldilocks did because, let's face it, that girl made some bad decisions. Okay, I'm Dan, bye.
