Why Size Matters for Air Conditioners

Monday, March 27th, 2017 at 11:00 am

If you’ve ever been out shopping for a new air conditioning system, then you know just how many different factors there are to consider. It can be very easy to get lost amid all the ratings and other numbers that beset you when you’re just trying to find a way to keep cool. It’s very important that you take note of some of those ratings, though, if you want to get the most out of your new air conditioner. If you install a new system that isn’t suited to your home, you’re just going to have to replace it sooner rather than later. One of the most important AC qualities that you need to make sure matches your home is the size of the system.

Improper Sizing and Its Effects

When we talk about the size of an air conditioner, we aren’t just talking about the physical dimensions of the system. Yes, it would be pretty foolish to install an air conditioning system that you physically don’t have the space to accommodate. Just because the system fits in the physical space allotted for it, however, doesn’t mean that it is properly sized. We’re also talking about the output level of the system when we discuss size.

For example, if you install a system that is oversized for your home, that means that it actually generates more output than it needs to for the amount of space it’s conditioning. An oversized air conditioner will be prematurely shut down by the thermostat every time it begins its cooling cycle, a behavior known as short cycling. Short cycling may seem harmless, but it’s actually the exact opposite.

All air conditioning systems are designed to operate in these cycles, where they put out a certain amount of cool air and then rest, making only slight adjustments to maintain the temperature in the desired range. If the system is not allowed to finish its cycle, its efficiency will drop significantly. The parts in the air conditioner will also wear down much faster than they otherwise would have, leading to more breakdowns and shortening the lifespan of the system significantly.

If the air conditioner you install is too small for your home, you will end up with a variation on the same problem. The system will not short cycle, but will instead operate for longer than it was meant to. This causes the system to wear down at an accelerated rate, similar to if it were too large. Eventually, the air conditioner will prematurely expire and need to be replaced.

Though it may seem a small thing at first, you must make sure that your air conditioner is properly sized if you want to get the best return on your investment in it. Consult with a professional if you’re not sure what rating your air conditioner needs to have to match your home.
