How to Install a Window AC?
How to Choose a Best Window AC For Your Home?
Here are some of the most important factors to consider when choosing which is the best window air conditioner unit to purchase:
The size of your window
Make sure that the unit is the right size for the window you plan to mount it in. Be sure to pick a window air conditioner that will fit your window.
Usually window air conditioners come with installation kits to fit certain common window sizes – just because the unit will fit in a window does not mean that the installation kit will fit. Also, make sure you have enough help in installing the unit (most are very heavy).
The energy efficiency and energy requirements
Look for high-efficiency units. Efficiency is measured by the EER (energy efficiency rating). All new units sold in the US must clearly display the EER. You should be mindful of the EER while choosing the best window ac in India for your home.
A higher EER is better, and a higher EER air conditioner often costs less in the long run than a less efficient unit. As far as electrical requirements, most window air conditioners do have robust energy needs, and even if the unit you are purchasing does not require a 220 Volt outlet, you might want to make sure that it can have a dedicated circuit (otherwise, if you run other high amperage appliances on the same circuit, you might trip a breaker).
Of course, you should at least make sure you have the appropriate electrical connection (120 Volt or 220/240 Volt) before purchasing the air conditioner. While Buying the best window ac in india, kindly consider it as one of the most important factors.
Your BTU requirements
The ability of a unit to cool an area is measured in BTU/hour. The higher the BTU, the more cooling power the unit has. This is probably the most important consideration. You want to get a unit with a capacity as closely matched to your needs as possible.
A unit that is not powerful enough will run constantly and will never properly cool the room. A unit that is too powerful will “short-cycle”- it will cycle on and off over and over again, only remaining on for short periods of time.
Short cycling is bad for the compressor- it could substantially shorten the life of the air conditioner, and the air conditioner will not dehumidify appropriately- so while the air in your room might be a comfortable temperature, there could be an uncomfortable level of humidity.
The ideally sized unit will run at its maximum capacity on the few hottest days of the year and run somewhat under capacity at other times. Make sure you have a rough estimate of the sizes of the rooms you want to cool before you start shopping. This is one of the most important factors while purchasing the best window ac in India for your home
Our team of 91airconditioners has done detailed research on these factors and has chosen the above 5 listed Window Air Conditioners best for you.

Working of a Window AC?
Air conditioning is provided through the removal of heat. An air conditioning system, or a standalone air conditioner, provides cooling, ventilation, and humidity control for all or part of a house or building. You can take a look at the clip given below to get a better understanding of the air conditioner working principle.
Air conditioners employ the same operating principles and basic components as your home refrigerator. Refrigerators use energy (usually electricity) to transfer heat from the cool interior of the refrigerator to the relatively warm surroundings of your home; likewise, an air conditioner uses energy to transfer heat from the interior of your home to the relatively warm outside environment.
The refrigeration cycle consists of four essential elements to create a cooling effect. The system refrigerant starts its cycle in a gaseous state. The compressor pumps the refrigerant gas up to high pressure and temperature.
From there it enters a heat exchanger (sometimes called a “condensing coil” or condenser) where it loses energy (heat) to the outside. In the process, the refrigerant condenses into a liquid. The liquid refrigerant is returned indoors to another heat exchanger (”evaporating coil” or evaporator).
A metering device allows the liquid to flow in at low pressure at the proper rate. As the liquid refrigerant evaporates it absorbs energy (heat) from the inside air, returns to the compressor, and the cycle repeats. In the process, heat is absorbed from indoors, and transferred outdoors, resulting in cooling of the building.
An alternative to central systems is the use of separate indoor and outdoor coils in split systems. These systems, although most often seen in residential applications, are gaining popularity in small commercial buildings. You can take a look at the schematic diagram given above to get a better understanding of the air conditioners parts
The evaporator coil is connected to a remote condenser unit using refrigerant piping between an indoor and outdoor unit instead of ducting air directly from the outdoor unit. Indoor units with directional vents mount onto walls, suspend from ceilings, or fit into the ceiling.
Dehumidification in an air conditioning system is provided by the evaporator. Since the evaporator operates at a temperature below the dew point, moisture in the air condenses on the evaporator coil tubes.
This moisture is collected at the bottom of the evaporator in a condensate pan and is removed by piping it to a central drain or onto the ground outside. A dehumidifier is an air-conditioner-like device that controls the humidity of a room or building.
It is often employed in basements that have a higher relative humidity because of their lower temperature (and propensity for damp floors and walls). In food retailing establishments, large open chiller cabinets are highly effective at dehumidifying the internal air. Conversely, a humidifier increases the humidity of a building.
All modern air conditioning systems, down to small “window” package units, are equipped with internal air filters. These filters are one of the air conditioners parts that are easily available in the market. These are generally of a lightweight gauze-type element and must be replaced as conditions warrant (some models may be washable).
For example, a building in a high-dust environment, or a home with furry pets, will need to have the filters changed more often than buildings without these dirt loads.
Failure to replace these filters as needed will contribute to a lower heat-exchange rate, resulting in wasted energy, shortened equipment life, and higher energy bills; also low air flow can result in “iced-up” or “iced-over” evaporator coils, and then there is no airflow at all. Therefore while purchasing the best window ac in India, keep in mind that the filters it contains are easily changeable.
Additionally, very dirty or plugged filters can cause overheating during a heating cycle, and can possibly result in damage to the system or even fire.
It is important to keep in mind that because an air conditioner moves heat between the indoor coil and the outdoor coil, both must be kept just as clean. This means that, in addition to replacing the air filter at the evaporator coil, it is also necessary to regularly clean the condenser coil.
Failure to keep the condenser clean will eventually result in harm to the compressor because the condenser coil is responsible for discharging both the indoor heat (as picked up by the evaporator) plus the heat generated by the electric motor driving the compressor.
Outside, “fresh” air is generally drawn into the system by a vent into the indoor heat exchanger section, creating positive air pressure.
The percentage of return air made up of fresh air can usually be manipulated by adjusting the opening of this vent. So while purchasing the best window ac in India s, kindly check its working properly.
I hope this information will be useful to you and will help you in getting a better understanding of the air conditioner working principle
How to Save Electricity as much as Possible While Using Window AC?
There are certain basic things to remember when you plan to install your air conditioner or cooling system. Take time to read these tips for the best results. They will help you save money and increase the comfort of your home.
Air Conditioning Energy Saving Tips
It costs you more money and uses more energy to heat and cool your home than any other system in your home. Typically, 44% to 50% of your utility bills pay for heating and cooling your home. But the above-provided list of best window ac in India has AC’s which help you in saving a good amount of electricity.
Regardless of the type of home comfort systems, you have in your house, you can save money and increase comfort by properly maintaining and upgrading your equipment.
Keep in mind that an energy-efficient air-conditioner alone will not have as great an impact on your energy bills as using an approach that involves the entire house. If you combine proper equipment maintenance and upgrades with appropriate insulation, weatherization and thermostat settings, you can reduce your energy bills by up to 50%.
General Cooling Tips:
* Use house fans. House fans help cool your home by circulating cool air throughout the house. They are most effective when the outside air temperature is cooler than the inside and when operated at night. An attic fan can blow away hot air that accumulates in the attic. This can go a long way to help the efficiency of your air conditioning system.
* Set your thermostat as high as comfortably possible. By maintaining a minimum difference between indoor and outdoor temperatures, you’ll lower your overall cooling bill.
* Don’t reduce your thermostat setting to a colder temperature than normal when you turn on your air conditioner. This will not cool your home any faster and could result in excessive cooling and unnecessary expense.
* Set the fan speed on high, except in humid weather. When it’s humid, set the fan speed on low.
* Consider ceiling fans to help spread the cooled air more effectively through your home without greatly increasing your power use.
* Keep lamps and TV sets away from your air conditioning thermostat.
* Shade air-conditioning units by planting trees or shrubs, but make sure you do not block the airflow. A unit operating in the shade uses up to 10% less electricity than one operating in the sun.
* Close shades or curtains on east, south, and west-facing windows during the hours when the sun’s intensity is at its peak. Open curtains and windows during early morning and overnight hours when the air outside the home is cooler.
* Turn off the air conditioner if the house (or air-conditioned rooms) will be unoccupied for an extended period. Use a programmable thermostat (link to product page) to turn Air off and on automatically when you know the house will be unoccupied.
Here are a few more steps you can take to substantially improve your home’s energy efficiency.
Take a Holistic Approach to Total Home Energy Conservation
To achieve the maximum in total home comfort and energy savings, we recommend that you step back and look at the big picture of energy consumption in your villa. The fact is, your total home comfort and efficiency is the product of many systems: heating, cooling, lighting & electrical, plumbing and possibly others working together.
It is the interplay between these systems, combined with the size, age, physical features and location of your home, and even your lifestyle, that combine to produce the total energy efficiency of your home. Changing or upgrading one system, without considering the other factors will usually result in some improvement, but may not deliver the maximum possible benefit.
If you’re building a new villa or considering a major remodel or system upgrade, consider an Integrated Systems approach. It may cost a little more now, but will undoubtedly save you a bundle over time. Our skilled engineers and technicians will look at the big picture when designing a solution for your home.
Conduct a Home Energy Audit
The place to begin when evaluating your home’s overall energy efficiency and deciding how to reduce consumption and costs is with a Home Energy Audit. This takes into consideration much more than just your heating and cooling systems, and will give you a benchmark from which to make decisions and measure your energy-saving progress.
Here are some of the heating & cooling factors your audit should take into consideration:
* Insulation in walls, floors, and attic.
* Vapor Barriers in walls
* Quality of Windows – Single or double pane
* Heat loss around doors and windows
* Quality of insulation indoors
* Integrity of ductwork “- Any leaks
* Cleanliness of ductwork
* Use of “passive” solar energy
* Use of curtains and other window coverings to prevent heat loss
* Efficiency of heating and cooling systems – Condition of filters, etc.
Consider Purchasing an Annual Maintenance Agreement
You’ve heard the old adage, “If it ain’t broke, don’t fix it?” Well, that doesn’t apply to your air conditioner any more than it does to your automobile. However, when your system is operating properly, it is easy to forget.
Regular maintenance will save you the time money and headaches of premature system failures and major repairs. It will ensure that your system is always working at peak efficiency and help you avoid excessive energy costs.
Make sure your Air Conditioner is properly sized so that it provides you with Better Cooling. For the you can refer our list of best window ac in India (2019) given above.
Bigger Is Not Necessarily Better – A bigger room air-conditioning unit won’t necessarily make you feel more comfortable during the hot summer months and will most likely perform less efficiently and less effectively than a smaller, properly sized unit.
Room units work better if they run for relatively long periods of time as opposed to being constantly switched on and off. The longer running time an air conditioner is allowed to maintain, the easier it is for the unit to hold a more constant room temperature.
Running longer also allows air conditioning units to remove more moisture from the air, which reduces humidity and increases the comfort level in the room.
Check specifications carefully when choosing from the best window ac in India for your space. Central air-conditioning systems also require proper sizing. Professionals, however, should perform the sizing of your central air system.
Also, do not use the system’s central fan to provide circulation. Instead, use circulating fans in individual rooms. Make sure you set the fan of your central air system to shut off at the same time of your cooling unit (compressor).
Use an Air Conditioner with a high Efficiency Rating
Select a room air conditioner that has an A rating or 10 or higher.
