Types of Air conditioner units (Pros and cons)

Following are the major type of air conditioner system you can choose from. Choosing the right system will depend on your budget, house construction and for how much area you want to cool. We also mentioned the pros and cons of each type below.

  • Window Air Conditioner
  • Split Air Conditioner system
  • Portable Air Conditioner system
  • Central Air Conditioner system

Window Air Conditioner

In Window Air Conditioner, all the components such as the compressor, expansion valve, condenser, and cooling coil are enclosed in a single unit box. They are easy to install and don’t require modification such as installing ducts or making holes in walls.

The window air conditioner is an ideal choice if you are in the rented apartment. You can install and remove it whenever you change your apartment. They are designed and works best for rooms with a smaller area. But now day’s high capacity window AC units are available which can be sufficient for the area up to 650 square feet. Its water drains do not need to be emptied as they are outside.

The drawback of the window air conditioner is that they are not as quite other systems. They are heavy and you may need help while installing and removing them. If you install them directly outside the window, then it limits the use of that window.

Split Air Conditioner system

The split air conditioner consists of two main parts: the outdoor unit and the indoor unit. The outdoor unit of a/c is kept on or near the wall outside of the room. The outdoor unit houses components such as the compressor, condenser coil, and the capillary tubing.

The indoor unit is comprised of the cooling fan and evaporator. Copper tubing system provides the connection between the indoor and outdoor unit.

This type of air conditioner is suitable if you don’t want to limit your window usage by using the window air conditioner. With this, you can adjust room temperature according to individual rooms. They are highly recommended if you want to save on energy and want to cover spaces where another system is not possible. The main problem with this system is the appearance of the indoor unit on the wall. You have to mount a big indoor unit of a/c on the wall which some people don’t find visually appealing.

Portable Air Conditioner system

Portable Air conditioner is made with a moveable single unit, positioned on the floor of the room. They are easy to set up and can be moved to different rooms easily. Portable a/c system sucks the ambient room air and vents out warm air through exhaust outside. Some additional features like dehumidify help in removing humidity in the room.

Even though portable a/c system is inside the room, you will still require an area to discharge warm air. This can be done using window or sliding doors. They are noisy and not as efficient as other air-conditioning systems.

Central Air Conditioner System

In this system, big compressor unit is placed outside and cool air is provided using vents on the wall. In this system, air flows in ducts from the compressor to vents. This system requires huge upfront cost but saves much more energy as compared to regular individual a/c units for the room.

This system is extensively used in apartment building, hotels, gyms, movie theaters, and industries. You will require a professional and permit (depending on your region) before installing this system.

Central A/c system is almost hidden behind walls except for the vents in the room.

How to choose the right size (capacity) of the Air conditioner

Selecting the right capacity of an air conditioner is important as it affects both upfront and regular electric bills. You should avoid buying both under power and overpower air conditioner system.

There are many factors which to consider for determining the right capacity. But the most important is the floor size. Other factors are ceiling height, sun exposure, and the number of people usually using that area.

Problem with overpowered a/c system is its upfront cost. It will cost you more and will lack control of comfortable climate. It will cool the area of the room at a much faster rate while unable to control the moisture.

According to The Exhaustive Guide to Heating and Cooling Your Tiny Home, every one point increase in your EER equates to about a 10 percent reduction in cooling costs.

As for underpowered a/c unit they are simply unable to give you the desired temperature. They may be cheaper in starting but eventually, you will end up paying the higher cost for electricity.

Calculate the required capacity according to your room size

The cooling capacity of the air conditioner is measured using BTU (British thermal unit). You can easily calculate the BTU required for your room by following method.

Length of room (in feet) X width of the room (in feet) = Area of the room (in square feet)

Area of the room (in square feet) X 25 = Minimum BTU required

For Example width of your room is 12 feet and length is 12 feet.

So the area of your room will be 12 x 12 = 144 Square feet.

Now multiply 144 with 25 which is equal to 3600.

Hence you for this above-mentioned size room you will require best air conditioner capacity should be more than 3600 BTU’s.

Recommended BTU’s according to room size

Check out the following table to select the required BTU for the best air conditioner according to your room size.

Room size (square feet)BTU’s required
Less than 1505,000
150-2306,000
