While choosing a ductless air conditioner to your home, office or any other building, there are many things which has to be taken care of and you will have to make certain trade offs between cost vs. quality or capacity.

The ductless air conditioners come in various varieties suiting different needs and having different features. Deciding on an air conditioner which matches your budget and expectation along with the required features is a very important task (Ex It would not be a wise job to buy a 2Ton capacity ductless air conditioner to a small house with a single room, not only the cost of the ductless air conditioner would be higher, the electricity requirements would also be much much higher). I would not tell you the best brand or the model to choose (Since the technology is ever evolving with new products every day). But in the subsequent sections I would give you a brief idea, which would help you in choosing a good ductless air conditioner which would possibly meet your needs and be cost effective. Some important factors are:

The climate of your city

The ductless air conditioning unit  should be suiting the climate of your residing city/town. Cities with higher temperature would require high capacity Air conditioners compared to the cities with lower average temperature. A city with very less temperatures should have a good heating unit as well.

The size of your room

A small size room of size around 80 sq feet and having a temperature of around 38-40 degrees would require a ductless air conditioning unit of capacity around 1Ton and the input power would be of around 1.2 Kilo Watts, while that of a 120 sq feet room and having the same other cooling requirements would require a ductless air conditioner of 1.5 Ton and the input power would be of around 1.6 Kilo Watts. Similarly big corporate buildings would require more than one cooling units.

The floor of residence

The rooms in top floors will generally be hotter than the one’s below. This is because the top floor is the one which absorbs the most sunlight and in the process acts as a shield to the lower floors. Hence the top floor would need an air conditioner of slightly higher capacity than the one beneath.

There are several other features as the inverter technology, the plasma filter technology, the anti bacterial filter etc. The inverter technology provides more even cooling and reduces the electric energy consumption. The plasma filter technology which does the air purification and generates ozone and plasma, the anti bacterial filter is also a type of air purifier.  The ductless air conditioners with these features can be helpful according to the requirements.
