The Importance of Sizing a New Air Conditioner

The Importance of Sizing a New Air Conditioner

Ideally, every air conditioner could get through the summer without running into trouble, allowing you to assess its state in the cooler months of the fall when you don’t need it. But that’s not always possible, especially with an older air conditioner ready to be put out to pasture. Older air conditioners often fail in late summer, having been running for months on end with worn parts and an overall system ready to be put out to pasture. It’s hardly the most ideal time, and you often need to move quickly to get a new system installed lest the stifling temperatures turn your entire home into a broiler.

Just because you need to move quickly, however, doesn’t mean you should skip over the important steps required to install a new one. The proper sizing of a new air conditioner, in particular, is a vital part of the process. If your new system isn’t sized the right way, it’s going to cause a great deal of trouble.

Why Sizing Matters

When we refer to the size of the air conditioner, we’re not referring to its physical size (though that can be a factor when installing a new one too). We’re referring to the air conditioner’s power output levels, which need to be balanced against the size of the space it needs to cool in order for it to function at its best.

You probably don’t need to be told that an underpowered air conditioner will cause a lot of difficulties: running constantly without ever really getting the home cool. But it may surprise you to learn that an overpowered air conditioner can be just as problematic, if not more so. It sounds counterintuitive: don’t you WANT the air conditioner to be as powerful as it can be? Unfortunately, you don’t.

Air conditioners use much more energy starting up and shutting down than they do simply running, which is why you want your system to run for at least fifteen minutes at a time. And overpowered air conditioner will do the job too quickly however. The system will shut down only to turn on again a short time later: over and over again throughout the entire day.

The tendency is called “short cycling,” and as you can imagine, it’s very damaging to your air conditioner. Not only will it waste a great deal of energy – raising your monthly cooling bills in the process –but it can subject the system to an undue amount of strain. That means breakdowns will take place sooner than they should and repair calls tend to be a lot more expensive to boot. Worst of all, there’s not much you can do about it once the overpowered system is installed: just live with the added expense or get the whole system replaced.

Trust Your Technician

A good technician will make the proper measurements of your home: gauging not only the square footage but things like the level of insulation that will affect its ability to retain cool air. That gives you a new system that is neither too small nor too large, but just right.
