How To Buy An Air Conditioner For A Mobile Home – Shopping And Installation Tips

Air conditioning refers to technological heating, cooling, disinfection or ventilation that alters the condition of the atmosphere. In many parts of the world, the hot summer months become unbearable without a good cooling system. The option in the type of air conditioner system to utilize depends on many factors including the size of the room to be cooled and the amount of heat generated in an enclosed space. A good air conditioning designer will recommend one of the following types of air conditioning systems depending on your requirement(s):

1. Window Air Conditioner

Many people utilize this type of air conditioner in almost all applications but they are mostly utilized in single rooms. A window air conditioner has all it parts (condenser, compressor, evaporator, expansion coil or valve and cooling coil) confined in a single box. This unit fits correctly in a slot made in a window sill or the wall of a room. The unit’s hot air exhaust system faces the outer part of the room while the cool air return system faces the inside of the room.


a) It comes in a single unit

b) Requires little effort while installing it

c) Cheaper than the other types of air conditioners


a) The unit produces uneven cooling in the room

b) The unit produces a lot of noise while operating

2. Split Air Conditioner

This type of air conditioner comes in two separate parts: the indoor unit and the outdoor unit. The outdoor unit houses components such as the condenser, compressor and expansion valve fitted outside the room. The indoor unit constitutes of the cooling coil, evaporator and cooling fan. This type of air conditioner cools single rooms in hotels, apartments and offices.


a) Its internal unit uses little space during installation

b) More silent than the window air conditioner

c) Does not affect the internal decoration of your home

d) Can be set up in a room that has no windows


The major disadvantage of a split air conditioner is that it is not energy efficient.

3. Central Air Conditioner

This type of air conditioner is utilized for cooling big buildings, offices, entire hotels, houses, gyms factories and movie theaters. A central air conditioner comprises of a big compressor with the capacity of producing a huge amount of air to either cool or heat a building. Central air conditioners are packaged in two units: the first is the condensing unit and the second one is the evaporative unit. The two units are connected via refrigerant tubing. The condensing unit constitutes condensing coils, compressor and condensing fan while the evaporative unit constitutes an expansion valve and an evaporator coil.

The evaporative unit is usually placed in an enclosed space of the heating system so as to utilize the same ductwork as the heating system.


a) The Units are quieter than other types of air conditioning units

b) They can utilize a similar ductwork as the central air furnaces

c) The unit can be placed outside a building thus creating space for other purposes


a) They require air ducts to pass cool air in the room. The air ducts can sometimes leak causing the unit’s efficiency to decrease.

b) Replacing older models of the central air conditioners is so expensive.

4. Portable Air Conditioner

These are free standing air conditioners that cool a room by pulling fresh air in the room, removing heat from the room and dehumidifying the hot air and bringing back the air in the room as cool air. Portable air conditioners should be placed near a window or a specific hole meant for the air conditioner in order to push out the hot air from such openings. All portable air conditioners have exhaust accessories and window kits that allow you to install them easily.

Some portable air conditioners have mobile wheels that allow the unit to be put in any part of the room. They also have a hose vent to expel the hot air to the outer part of the room. This type of air conditioner has all its components in one box.


a) Ability of cooling a small area without the need of a large air conditioner

b) The Unit is easy to set up


The major disadvantage of this AC unit is that it is too noisy while in operation and that it is not energy efficient.
