AC Installation: Why Bigger Is Not Always Better

One of the biggest HVAC myths we hear most often is that homeowners believe that the bigger an air conditioning system is, the better it will perform. So when it comes to replacing your air conditioner this season, you’ll want to take that into consideration. Air conditioning systems are similar to the vehicle you drive. The more you drive in stop-and-go traffic, the quicker your vehicle wears down. The more an air conditioner rapidly shuts on and off to compensate for its size—called short-cycling—then the faster it breaks down.

The Problem with Short-Cycling

When your too-large AC system short-cycles, it forces the system to work harder and does not allow your system to do one of the things it does best: dehumidify your air. This is because air conditioners don’t usually start dehumidifying indoor air until they’ve been running for 8–10 minutes, which short-cycling does not allow for. Thus, excess moisture develops and causes problems with your home and your health. You’ll likely start to notice warped furniture and wallpaper, in addition to a stuffy uncomfortable feeling in your living space.

So How Is My System Sized?

Our HVAC professionals look at a number of factors when sizing an air conditioning system. They look at the home’s square footage, but that’s not all. They’ll observe your ceiling height, location and number of windows and doors, your insulation, how many occupants are in the home, and more. Additionally, they’ll consider any energy-efficient upgrades you’ve made such as extra insulation or weather-stripping, as this may decrease the size of AC system you need.

Whether you are replacing your current system or getting a new air conditioner installed in your home for the first time, be sure to ask your HVAC contractor how they are going to determine the size you require. A reputable HVAC professional understands that there is a lot more to sizing the unit that the square footage alone.
