A central AC system is a good choice when you are trying to cool every room in a big house. On the other hand if you live in a small home, or you don't use every room in a big home, you may not need a central air system. Ductless AC systems have many advantages over central-air systems.
What is a Ductless AC System?
A central AC system will use a system of ducts to push cold air to every room in your home, or at least every room with an AC vent. A ductless system eliminates the ducts by placing an evaporator unit in the rooms you want to cool. While this can increase efficiency, ductless systems are limited in that they will only have up to four evaporator units, which means you can only cool four rooms at a time.
What Are the Weaknesses of a Central Air System?
One of the main concerns with a central-air system is that you have to cool rooms whether you are using them or not. While it is true that you can close the vents to rooms when they are not in use, doing so will increase the pressure inside your ducts. Over time the pressure created by the air moving through your ducts will break down the seals on your duct's joints and seams. Leaky ducts can decrease AC efficiency by up to 40%. Thus, if you are not using every room in your home, you may want to think twice about installing a central air system.
What Are the Advantages of a Ductless AC System?
A ductless AC system will have a separate thermostat for each evaporator unit you install. This means you can control the amount of cooling in each room. A room on the side of your house that faces the sun will likely need more cooling than a room on the opposite side; individual thermostats allow you to keep each room comfortable, whereas the single thermostat that comes with a central-air system would cause you to keep one room too cool or the other room too hot. By placing evaporators only in the rooms that need the most cooling, you can target your cooling and decrease the amount of wasted energy created be cooling rooms that don't need it.
A ductless AC system makes a lot of sense if you live in a small home or apartment. However, even if you live in a large home, a ductless system can still work provided that you don't use every room in your house all the time. If you are wondering if a ductless system might be right for you discuss your situation with an AC expert, such as Weather Control Air Conditioning, Inc.
