It’s summer and it’s hot. When you are looking for some relief from the heat, you likely turn to the inside of your home to find comfort. If your home doesn’t have central air conditioning, or there are rooms without vents or that never seem to cool down enough, you may turn to whatever solution you can find, to gain your home’s ideal temperatures. If you use window ac units to cool down your home, or even just a room or two, while there are other options available (i.e. ductless air conditioning, central ac, etc.), you may not see the need to change. Should you? Is that window AC unit costing you more than you even realize? Let’s review.

What are Window Air Conditioners?

In case you aren’t familiar with these cooling devices, a window air conditioner is the simplest type of AC unit. It’s a single unit with all the parts and components contained inside one box or casing. This type of air conditioning is usually mounted or installed in a window and plugs into an electrical outlet. Window units operate independently from a home HVAC system. Like other air conditioning units, window AC units use refrigeration properties to remove heat and humidity from a room while cooling air to circulate into the room.

While central air conditioning is a solution for whole home comfort, window AC units are used more for smaller areas, and multiple units may need to be used to keep your home feeling comfortable in the heat.

Many people turn to this type of cooling, when their home doesn’t have central AC or existing ductwork and they don’t want to face the cost of having that or ductless AC installed. The question is, is that window AC unit costing you more?

Is that Window AC Unit Costing You?

It’s rather difficult to compare window AC units versus central AC, because they serve different purposes. Central air conditioners move cool air through a system of supply and return ducts. Supply ducts and registers (i.e., openings in the walls, floors, or ceilings covered by grills) carry cooled air from the air conditioner to the whole home. Window AC units typically only cool a limited space like a room or two (depending on the size of your unit).

When considering if window AC units cost you more than central air conditioning, you should compare the energy usage for your cooling system. A central air unit uses more energy to cool your home than other cooling choices; however, they are cooling a larger space and are typically more efficient. As Mr. Electricity states, a window unit uses anywhere from 500 to 1,440 watts to run, while a 2.5 ton central unit (about the size for a typical 1,500- to 2,000-square-foot home) uses about 3,500 watts.

Basically, to answer if that window AC unit is costing you, it really comes down to its main purpose. If you are looking to cool only a small area, a window AC unit may be okay; however, as a whole home solution, if you have multiple window units running, the energy usage and cost can really add up.

With window units there is a lot more risk of hot air entering and cool air escaping than with central AC or ductless cooling. That too can cost you and make your window air conditioning have to continuously run to keep up with the desired temperature and humidity levels. While installation of a window unit is simple and less expensive than other options, is it worth it?

Are Window AC Units Right for Your Home?

Is that window AC unit costing you? Like we said above, this really comes down to what you are using the cooling device for. If you plan to cool more than three rooms and have more than one or two window AC units, the energy consumption will likely cost you more than that of a central air conditioning unit.

A central AC unit adds resale value to your home, so you can recoup more of your investment, if you sell your home. Central AC allows you to cool more of your home at once and maintain more balanced temperatures than window units. Central air units should connect to your thermostat giving you more control over your home’s comfort, than a window AC unit allows. Also, central air units are also more efficient and let less cool air escape.
