The three main parts of the air conditioning unit are:

•    Compressor
•    Condenser
•    Evaporator

The fluid present in the unit arrives at the compressor as a cooling agent. The compressor then squeezes low-pressure gases and the molecules are packed in the fluid closer together so that they move faster with high energy levels and temperature. The compressor becomes hot because the fluid enters the condenser with high pressure leaving the compressor. It changes from gas to a liquid under the high pressure.

The sales of windows air conditioners are generally higher than those of Split air conditioning – for both domestic and commercial purposes. It does not occupy any space of the room as its body remains outside the room and fits on the window. However, the window air conditioners tend to generate noise over a period of time depending on their type and size. The occupants could become irritated by the noise.

Many homes do not have the provision for central air conditioners and window air conditioners block the windows.

The good news is that ductless air conditioning has been introduced which is as good as central air conditioning. This type of air conditioning has been popular in Japan and lot of other countries for some years now.

Ductless air conditioners can be used for home and office purposes.

Installing ducts is an expensive exercise. Ductless air conditioners are installed on high walls, exterior walls of the building and the ceilings of the rooms. It includes a compressor, which needs to be sheltered.

Most of us have air conditioners either at the work place or at home. We enjoy sitting in a fully air conditioned room, but do you know how it works? Are you fully aware about the cooling mechanism of an air conditioner?

Price, brand and many other things matter when looking to buy an air conditioner. The buyer also considers the look of an air conditioner.

The idea of the air conditioner is to cool the room but many brands try to sell their units by making them look fancier. The distinguishing factor between different brands would be how the air conditioners look.

Window air conditioners and wall air conditioners can be closely inter-related. The only difference is that window air conditioners are installed in a window whereas wall air conditioners are installed on a wall. Wall air conditioners are effective for a single room.

Installing a wall air conditioner requires a hole in the exterior wall of the room. It may cause trouble if the wall has pipes or wires running along it. An expert will be able to do the job if the walls are made of concrete or brick as it is not an easy task unless you are experienced and can do the job properly.

If one is looking to place an air conditioner in the room or other small places, a window air conditioner is the best option. They are designed to be fixed on the windows without taking up much space.

It is not possible for everyone because of budget constraints to buy central air conditioners so buying window air conditioners is a better idea if you are tight on budget. Also, central air conditioners require a lot more maintenance. Importantly, window air conditioners will not add excessively to your electricity bills.

It is very important to keep air conditioning filters in order. If the air conditioning filters are not maintained properly and cleaned at regular intervals, it will harm the air conditioner’s output and result in inefficient cooling especially when there is heat outside and you want to work or relax.

The electricity bill will also increase because of the unclean air filter. If there are dust particles on the filter, it puts additional load on the unit and may lead to an increased electricity bill. The cooling capability of the air conditioner will also be affected if the air filters are not maintained properly.
