Air conditioners are necessary to keep your home cool and comfortable. You may be asking yourself which type of AC is best for you. Window air conditioners, or “window units,” are typically cheaper than split air systems, But many people find them less powerful.

Which type of AC do you need?

Which type of AC do you need depends on the size of your house. Do you need an AC to cool your entire home? If so, window units are the best choice. If you have a smaller house and only need a small area to cool, you can turn to a split system.

Split air conditioning systems come in the form of a downstairs unit with a separate condensing unit for each room in the house. With a split system, each room can receive its own cool air, and they’re more efficient.
