Should You Buy a Split AC or a Window Air Conditioner?

As summer approaches, you might be thinking about buying a new air conditioner so that you aren’t sweltering during the dog days of summer. But deciding which unit to buy can be stressful.

One of the most common questions is should you buy a split AC? Or should you opt for a window air conditioner?

A window air conditioner includes the entire air conditioner unit inside one box. This type of unit is small enough to fit on your windowsill where it should be firmly attached to the frame. This can provide excellent cooling for a single room.

A split AC, is more expensive and more complicated. It includes two units that basically relies on an indoor and an outdoor unit.

Design: A window air conditioner comes in one unit with the compressor and condenser housed together. The unit is designed to sit on your windowsill and be anchored in place. By contrast, a split AC comes with two units. The compressor and condenser are in the unit outside your house while the air-handling unit is inside

Space: A window AC is about the size of a microwave and remains in the window. A split AC is larger because it comes with two separate units.

Installing: For DIYers, you can install a window AC very easily. You just need to anchor it to the window. A split AC, by contrast, may require professional installation because you need to connect tubing from the inside unit to the outside unit. This requires drilling holes through the wall.

Noise Level: A split AC is much quieter than a window unit because the noisiest part of the unit – the compressor - sits outside of your home.

Cooling Capacity: Both a split AC and a window unit do a good job cooling a room (especially when compared to the mediocre cooling capability of portable AC units). But a split AC can has much more power than a window unit and, as a result, is capable of cooling a much larger space than a window unit. In fact, some split ACs can blow cool air 30-40 feet.

Energy Efficiency: Interestingly, both the window AC and the split AC have very similar electricity needs and, therefore, cost about the same to run in terms of electricity costs.

Room Size: Window AC units are designed to cool rooms that are 300 square feet or smaller. By contrast, a split AC is capable of cooling larger spaces.

Cost: Window AC units are pretty reasonable. In fact, you can find some units priced at under $200. On the other hand, a split AC unit can cost quite a bit more. Moreover, you may also need to pay for professional installation depending on your situation.

Bottom Line: If you are looking to save cash or you are renting an apartment, you should probably go with a window AC. On the other hand, if you live in your own home and have some extra cash to spend, go with the split AC.
