We have become somewhat accustomed to the notion that “Bigger is Better.” Whether we are at a drive-thru where you can “super size” for a better “value” than a regular meal or driving the bigger truck or SUV so you can see over the other cars, we like things BIG.
A big fish is better than a small fish. A big boat is better than a small boat. And so on… you get the idea. Surprisingly though, bigger isn’t always better when talking about a new “high efficiency” cooling system. If you bought a new air conditioner today, it will probably be smaller than the one you bought 10 to 15 years ago.
Just replacing your old A/C with a new one the same size could cause you trouble down the road because it will be too big to meet your needs. This is, of course, assuming you have the appropriately sized air conditioner for your home now.
A cooling system too big for your home will cause frequent on-and-off cycling which will affect the humidity control in your home. Poor humidity control can lead to moisture in the air which, in turn, will lead to mold and mildew, not to mention, humid air that is just plain uncomfortable.
It is hard to imagine there is a service industry these days that is saying, “Not so fast… a bigger cooling system may NOT be what your home needs. You may need just a smaller, more efficient system to have your home feeling cool and save you money on energy costs.”
