Why Size Matters with your AC Installation


So, you’re in the market for a new air conditioning installation. At least, we’re going to take a guess that is why you’ve come across this blog post. If you have the budget, you’re likely tempted to purchase the biggest and best air conditioner you can find, right? That’s a great idea… except that it can actually be too big!

Yup, that’s right. An air conditioner can actually be too large for the space in which it is installed. Homeowners usually don’t consider this possibility–they know that an air conditioner can be too small but don’t really think about it the other way around. But in actuality, an oversized (overpowered) air conditioner can be just as detrimental to home comfort and the efficiency of your air conditioner as an undersized (underpowered) air conditioner. Read on to learn more!

Why You Don’t Want an Undersized/Underpowered Air Conditioner

As you probably understand a bit already, an undersized/underpowered air conditioning system simply will not be able to do its job and keep up with your home’s cooling needs. An underpowered air conditioner will have to run much longer than a properly sized system would, which is inefficient. This wears down on the unit, resulting in high energy bills and an air conditioner that can fail years before it actually should.

In addition, an underpowered air conditioner cannot keep your home as comfortable as an air conditioner should be able to. During our sweltering summer days, it’s easy to see why this would be a big problem. It’s wise to ensure that you have a properly sized air conditioner installed right from the start!

Why You Don’t Want an Oversized/Overpowered Air Conditioner

Okay, so what about an air conditioner that’s too large, or overpowered?

You probably think that this would be better for keeping your home cool enough. But the reality is, this is very inefficient. This is because optimal AC efficiency happens through continued operation and regular, timed cycles–and when an air conditioner is too big, this doesn’t happen.

Instead, the system goes through a process called short-cycling, where it turns on and off rapidly. This exacerbates wear and tear and is very draining on the system. Short-cycling isn’t something any homeowner wants to deal with. And unfortunately, when short-cycling is caused by an improperly sized air conditioner to begin with, the only “repair” available for it is to replace it altogether with an adequately sized system.
