Planning for a New Air Conditioning System? Get It Sized

new-air-conditionerSpring is here, and summer won’t be too far behind. If your air conditioner struggled last summer, or the warranty has expired and you feel like it’s clearly on its last legs, now is the time to get it replaced. Doing so means you’ll be able to take advantage of the new system’s improved efficiency and similar benefits as soon as the heat rises.

Installing a new air conditioning system requires a trained technician and a careful examination of your house. It also involves some careful calculations before you settle on a new make and model. None are more important than the proper sizing of the new system. By “sizing,” we don’t mean the physical size of the system (though obviously it will need to fit into the space your home provides). We’re referring to the power output levels which determine how much cooling power your new air conditioner puts out. Determining those levels is more complicated than it may initially appear.

Neither Too Large Nor Too Small

You can probably guess that an undersized air conditioner will not serve you well. It will run and run all day without ever getting your home cool: boosting your monthly costs and elevating strain on the system to boot. Homeowners rarely make the mistake of buying an underpowered unit.

Overpowered units can be just as damaging, however, and here, homeowners can often make a dreadful mistake. On the surface, it seems completely logical to install the most powerful unit you can. That will cool the house more quickly than normal after all: right?

It’s a logical assumption, but unfortunately, it’s dead wrong. Air conditioners use up far more energy turning on and turning off than they do simply running. For that reason, you want any air conditioner in your home to run for at least 15 minutes at a clip. If it doesn’t, it engages in a process known as short cycling: turning on and off multiple times throughout the day, far more often than it should. That increases the stress and strain on it considerably, as well as elevating your bills.

How the Technician Finds the Right Size

For your new air conditioner to work its best, it needs to find the sweet spot between being overpowered and being underpowered. That starts with measuring the square footage of your home to get a base line. The technician then factors in any specific features of the home that may influence how well it retains cool temperatures. For instance, a home with a lot of insulation in the walls will stay cool longer, and likely requires a less powerful system. On the other hand, a home that has large windows with a western-facing view will likely let a lot of sunshine in, which warms your house and requires a more powerful air conditioner. Once those calculations are made, the technician can help you find a perfectly balanced system.
