How to Clean Air Conditioner

While you may love the dipping temperature inside your home, the soaring electricity bills do bother you. Here's what you need to do to keep your AC fit and suck less power! Even if you might consider it a difficult job, room air conditioners need a swipe and wash once in a while to ensure they run without any snags. While it is not possible to clean split air conditioners at home, you can surely give your window air conditioner maintenance treat once in a while. If your window air conditioner refuses to cool, it means you it needs to be recharged, which in turn means it's time to send it to the service center. But it is always better to indulge in an occasional cleaning to save yourself from facing such a situation. Here are a few quick steps here that clearly enunciate the entire cleaning process.

Step 1: The first thing you need to do is clean the coils and filter. But before you can do that, you need to unplug the unit and remove it from the window space you've fixed it. But be careful while removing; the AC is heavy, so you might end up damaging weak bones, if any!

Types of Air Conditioners

Types of Air Conditioners

There are various types of air conditioning systems. The application of a particular type of system depends upon a number of factors like how large the area is to be cooled, the total heat generated inside the enclosed area, etc. An HVAC designer would consider all the related parameters and suggest the system most suitable for your space.

Split Air Conditioner System

Do you have a single room but no place to make a slot for the window air conditioner? No problem, there is an excellent option in the form of a split air conditioner. The split air conditioner can be installed in rooms and offices where you don’t want to disturb the setup of the room and avoid demolitions in your favorite space. The split air conditioner takes up a very small space of your room, looks aesthetically cool and makes very little noise, ensuring sound sleep for you when you return from your day’s hard work.
There are two main parts of the split air conditioner. These are:

Window Air Conditioning System

Window air conditioners are one of the most popular types of air conditioners being used. Whether it’s your study room, bedroom, or hall, the window air conditioner can be used for almost all types of spaces.

To fit the window air conditioner in your room, you need to make a slot in one of the walls of the room that is to be cooled. This system extends around two feet beyond the wall in the back side; hence behind the wall some free space should be available so that the hot air can be thrown easily from the condenser. The dew collected from the room is also thrown from the back of the air conditioner. Thus window air conditioners can be used only if there is place available in the wall to make the slot, and there is free space behind the wall for dissipating the heat and dripping water.

Packaged Air Conditioners

Packaged Air Conditioners


The window and split air conditioners are usually used for the small air conditioning capacities up to 5 tons. The central air conditioning systems are used for where the cooling loads extend beyond 20 tons. The packaged air conditioners are used for the cooling capacities in between these two extremes. The packaged air conditioners are available in the fixed rated capacities of 3, 5, 7, 10 and 15 tons. These units are used commonly in places like restaurants, telephone exchanges, homes, small halls, etc.
As the name implies, in the packaged air conditioners all the important components of the air conditioners are enclosed in a single casing like window AC. Thus the compressor, cooling coil, air handling unit and the air filter are all housed in a single casing and assembled at the factory location.
Depending on the type of the cooling system used in these systems, the packaged air conditioners are divided into two types: ones with water cooled condenser and the ones with air cooled condensers. Both these systems have been described below:

Central Air Conditioning Plants

The central air conditioning plants or the systems are used when large buildings, hotels, theaters, airports, shopping malls etc are to be air conditioned completely. The window and split air conditioners are used for single rooms or small office spaces. If the whole building is to be cooled it is not economically viable to put window or split air conditioner in each and every room. Further, these small units cannot satisfactorily cool the large halls, auditoriums, receptions areas etc.

A/C Compressors

If the entire air conditioning system is looked at as a body, the compressor is best described as its heart. Its basic function is to pump refrigerant--the system's blood, here known primarily as Freon -- throughout its closed loop of pipes and tubes. However, the compressor provides added functions, including compression of the vapor refrigerant. This process raises the temperature of the vapor to above the outside ambient temperature, thereby letting the cooler outside air be forced through the system's condenser coils by the compressor. This heat exchange process leads to the refrigerant changing state from a vapor to a liquid, eventually making it so the now unheated air can be pumped back into the room, maintaining the air at the desired temperature.
