Annual AC operation : 8 months.It is often confusing which ac to buy for your home, window or split ac. Both have their advantages and disadvantages. The ideal ac which suites best and has the maximum star ratings is the best for you. We will assist you in choosing between window and split air conditioner These are hanging out of many house windows. This is the most used and economical air conditioner system. It is a single unit, which sits in a window or an opening in a wall with its rear releasing hot air outside and the front part releasing cool air into the room. Windows AC has size limitation and doesn’t go beyond 2 Ton capacity The splitting of the two units in an AC allows one to install the cooling unit inside and the hot noisy compressor unit outside with flexibility.

Since two units are separate they can be larger or smaller, hence two indoor small units can be connected to one large outdoor unit.Chiller efficiency depends on energy consumed. Absorption chillers are rated in fuel consumption per ton cooling. Electric motor driven chillers are rated in kilowatts per ton cooling. If a chillers efficiency is rated at 1 KW/ton, The term kW/ton is commonly used for larger commercial and industrial air-conditioning, heat pump and refrigeration systems. The term is defined as the ratio of energy consumption in kW to the rate of heat removal in tons at the rated condition. The lower the kW/ton the more efficient the system. kW/ton = Pc / Er         (1) Pc = energy consumption (kW) The Coefficient of Performance - COP - is the basic parameter used to report efficiency of refrigerant based systems. The Coefficient of Performance - COP - is the ratio between useful energy acquired and energy applied and can be expressed as COP = Eu / Ea         (2) COP = coefficient of performance Eu = useful energy acquired (btu in imperial units) Ea = energy applied (btu in imperial units) COP can be used to define both cooling efficiency or heating efficiency as for a heat pump.

COP can be used to define the efficiency at single standard or non-standard rated conditions, or as a weighted average of  seasonal conditions. The term may or may not include the energy consumption of auxiliary systems such as indoor or outdoor fans, chilled water pumps, or cooling tower systems. COP can be treated as an efficiency where COP of 2.0 = 200% efficiency. For unitary heat pumps, ratings at two standard outdoor temperatures of 47oF and 17oF (8.3oC and -8.3oC) are typically used. The Energy Efficiency Ratio - EER - is a term generally used to define cooling efficiency of unitary air-conditioning and heat pump system. The efficiency is determined at a single rated condition specified by an appropriate equipment standard and is defined as the ratio of net cooling capacity - or heat removed in Btu/h - to the total input rate of electric power applied - in Watts. The units of EER are Btu/Wh. EER = Ec / Pa         (3) EER = energy efficient ratio (Btu/Wh) Ec = net cooling capacity (Btu/h) Pa = applied electrical power (Watts) This efficiency term typically includes the energy requirement of auxiliary systems such as the indoor and outdoor fans.

The changing times and climate have made this an absolute necessity for everyplace and everybody. Be it households, offices, malls or any other public places, air conditioning is ubiquitous.

The average sale of air conditioners in India is pegged at around 3.5 million units per year. This humungous number illustrates the growing popularity and need for these utility machines. The fact that almost all new buildings come with a designated space for the fitting of air conditioners proves that there is a general acknowledgment of the indispensable nature of air conditioners. One will always find someone rushing into air conditioned restaurants or buildings to escape the heat and humidity.There are two main types of AC i.e. Window AC and Split AC. One can choose any of this depending on the place that it needs to be installed. A window AC requires minimal installation efforts while the split AC installation can be a bit time consuming as it consists of two units- indoor and outdoor. The most popular type nowadays is Spilt AC because they are quieter, aesthetically good looking and offer more installation options as they are not restricted to window space. The window AC price is usually lower as compared to a spilt AC price and they are ideal for small to medium size houses.

Since the AC becomes a part of the room decor, one must take into account how well it would fit and look in the room. The other type of ACs available in the market are-Ceiling Mounted ACs and Floor Mounted ACs, but they are usually suitable for office/commercial space.There are several factors that need to be considered while buying an Air Conditioner. Here are some of them,This depends on the size/area of the room where the AC needs to be installed. Larger the area, more will be the required capacity. The ACs are available in different capacities from 0.75 ton, 0.8 ton, 1 ton, 1.2 ton, 1.25 ton, 1.5 ton, 1.75 ton, 1.80 ton, 2 ton, 2.2 ton, 2.5 ton and 3 ton. Generally an area of 120 -140 sq. ft. will require 1 ton AC whereas a 1.5 ton AC is sufficient for an area of around 150 -180 sq. ft. and so on. However the equation may change if you own a house at the top floor.With the increased attention to global warming and the urgent need to save electricity, AC manufacturers have come up with novel energy efficient technologies that drastically reduce the power consumption.

Therefore nowadays ACs come with Star or Energy Efficient Ratings (EER) which is decided or standardized by BEE (Bureau of Energy Efficiency). The ratings are on a scale of 1 to 5. of stars, the less will be the unit consumption of electricity (i.e. higher energy efficiency) and lesser will be your electricity bill. Thus, one should opt for Ac with higher rating if the usage is high. The new entrant to the ratings is an Inverter AC which is higher than a 5 star. Generally a 5 star AC or Inverter AC is recommended for office/commercial space whereas a 3 or 4 star AC is recommended for residential use.Undoubtedly, the price plays an important role while buying an AC. The price mainly depends on capacity and the energy rating. So higher the rating or capacity, higher will be the price. The inverter or 5 star ACs are usually priced 15-20% higher than the ACs with lower energy ratings. Within the same rating or capacity, the price varies depending on the brand.The AC market space is very crowded with presence of domestic as well as international brands.

Some of the most popular brands in this segment are Voltas, Blue Star, Daikin, Samsung, Panasonic, LG, Videocon, Godrej, Sansui, Lloyd, General and Haier. Other brands that produce quality Air Conditioners include Hitachi, Electrolux, Whirlpool and Sharp. One can refer the user reviews online while deciding the brand.In addition to the above mentioned key factors, there are some special features like Bacteria Control, Humidity Filter, Dust Filter etc. which can be considered while making a purchase decision depending on the need. These filters help to circulate clean air along with the cooling effect. Some of the other special features are Sleep mode, On-off timer etc. which provide more operational comfort.The noise level of ACs also needs to be checked before buying. It usually ranges between 19 to 60 decibels.A lot of thought must go into buying a product that will be a part of your home or office for the next few years. That is why it is essential to understand your cooling requirements, size of the room, maintenance required, your budget and potential utility bills when you finally make a decision.

Size plays an important role as oversized or undersized AC will significantly increase the electricity consumption and the bill.Here’s a chart for general reference,120 sq. ft: Up to 0.75 ton121-150 sq. ft: Up to 1 ton151-250 sq.ft: Up to 1.5 ton251-400 sq.ft: 2 ton or aboveInverter or 5 star ACs are most energy efficient. However one must also consider the usage as these ACs are usually 15-20 higher in price. So a 5 star or inverter AC is suitable for higher usage like that in an office or commercial space. Whereas a 3-4 star AC is suitable for residential purpose.The selection of star rating depends on the usage. The higher the usage, the higher star rating is recommended. So if your usage is above 8-10 hours then you can opt for an AC with higher energy rating.The selection of tonnage should depend on the space. The oversized or undersized AC will lead to higher consumption of energy and will put additional burden on your pocket. Please see the chart in question no. 1 as general reference while selection the tonnage.

This is a very tricky question and a difficult one to answer as it depends on your location. For example, one brand might have a service center at one location but might not have at another. The reach and the service level may also vary withing the city. It is best to ask experience of the people in your locality. It is safe to buy AC online provided you buy from trusted sellers (e.g. Amazon, Flipkart, Snapdeal, eBay etc.). Please refer the return/refund/replacement policies and read the T&Cs carefully.Filter is not a must-have functionality. However, if the AC is operated in a room which is always closed, then it leads to accumulation of bacteria and reduces the quality of air. In order to avoid this, one can opt for an AC with filter.Voltage stabilizer is recommended if there is frequent voltage fluctuation in your area. If there is stable voltage, then one can skip the stabilizer.Note: Inverter ACs can manage voltage fluctuations better.If the environment in your area is not corrosive i.e. air is not too hot & humid, then it is fine to go for an Aluminium condenser.
