How do Air Conditioners Work?
To understand how air conditioners work, you must first understand that they all operate on the same natural principle: evaporation is an endothermic reaction.
That is, the act of evaporation absorbs heat from the surrounding space. That’s why sweat cools you down and how air conditioners work. It draws away your body heat as it evaporates and your skin dries out.
The basic unit of the air conditioner consists of a compressor, a condenser, an evaporator unit and two fans.
Consider for a moment that an air conditioner is essentially a refrigerator for your home! It contains the same basic parts, but instead of cooling the insulated compartment, the heat-absorbing evaporator and heat-generating condenser are exposed to the ambient air inside and outside your home, respectively.
Structurally, the evaporator and condenser are identical and usually consist of a wound brass tube with a large number of fins attached to it. The fins provide more surface area with air, which aids in the heat exchange cycle.
These tubes carry a refrigerant, such as freon, mixed with a small amount of oil, which lubricates the compressor.
The heat exchange cycle begins when the cold refrigerant vapor enters the compressor, which packs the vapor particles into high pressure, high temperature vapor before it enters the condenser.
As mentioned earlier, the metal fins help the condenser to release the stored heat of the vapor, thereby converting it into a pressurized liquid.
This liquid then passes through the narrow opening of the expansion valve into the evaporator where the pressure drops rapidly, causing the liquid to turn back into a gas.
This evaporation absorbs heat from the surrounding air, assisted by the metal fins that are also present on the evaporator.
The cooled vapor is returned to the compressor – the cycle is completed and the air conditioners work just like that!
Two fans additionally contribute to the process of heat exchange with the ambient air on both sides of the cycle, blowing around the fins of the condenser and evaporator.
An air conditioner technically only transfers unwanted heat to another area; it doesn’t fix it. During the cooler months, some systems can even work like heat pumps, working in reverse!
How to Choose the Best AC Brand in India 2023?
The number of air conditioner features a buyer can understand really shows how far the technology has come over the years.
The following is a brief description of the characteristics of the air conditioner that you should pay attention to when purchasing the unit.
BTU output
This is the cooling capacity of the air conditioner. Choosing the right BTU for your space is critical to air conditioner performance. Our Air Conditioner Sizes section will help you choose the right one for your needs.
Energy star rating
Qualified air conditioners are at least 10% more energy efficient than minimum federal standards. Check out our Energy Star rating and EER section to learn more.
Variable speed fan
Variable fans help control noise levels and system efficiency. Look for an air conditioner that has at least 3 modes. A stepless fan can provide even more functionality to the user and make the air conditioner even more Energy Star compliant.
Programmable thermostat and automatic timer
Being able to set your air conditioner to run automatically will help it run at peak efficiency, and setting a timer to only run when you’re at home will save you a lot of money in the long run.
Electronic control and digital display
Gives you greater accuracy in determining your comfort zone within a 1 degree range.
Dehumidifier functionality
Some air conditioners with a dehumidifier function can provide long-lasting comfort in late spring and early fall when keeping your home cool is not as necessary.
Quiet mode
The noise level of an air conditioner is one of the most important factors that consumers consider before buying. Units with this setting are relatively quiet and provide more comfort than just cooling.
Remote control
Typically, electronically controlled devices include a remote control. Excellent air conditioning function for units placed in large rooms.
Adjustable or oscillating louvers
They will help evenly distribute the air throughout the room. Note that almost all window air conditioners are better at directing air one way than the other. Keep this in mind when considering placing the device in your home before making a purchase.
Air filters and purifiers
Don’t worry about devices with filters that are difficult to remove and clean. One of the best air conditioner features to look out for is washable filters instead of replaceable ones whenever possible.
Some air conditioners can act as air purifiers and have ion cleaning mechanisms. Air ionization can improve the performance of your filter (provided it’s clean) and help purify the air.
If you have an air conditioner that uses this air purification technology, electrons are released that attach to impurities in the air and create ions.
These enlarged particles are then caught in a filter, attached to an ionizer plate, or deposited on floors and other surfaces in your home, to be vacuumed or dusted.
Chassis type
There are fixed and retractable chassis for window air conditioners. Fixed landing gear are the most popular, they are usually lighter and can be installed and removed depending on the season.
The retractable landing gear is usually found in units that operate through a wall coupler. This allows the owner to more easily perform maintenance or replacement of the window air conditioner.
Heat pump mode
Some air conditioners can work in reverse, effectively turning it into a heat pump. To learn more about how this happens, visit our How Air Conditioners Work section.
Warranty
This is one of the most basic features of an air conditioner and can certainly save you a headache! If the manufacturer is not responsible for their product, do not buy it. Look for units that have AT LEAST 1 year of warranty, including parts and labor.

Air Conditioner Size and BTU
Choosing the right air conditioner size for your space is an important step. You want your investment to turn your space into a true oasis, and to that end, you can purchase the most powerful unit you can find.
However, you want to avoid choosing an air conditioner size that is more suitable for a larger room than you intend to cool.
Many people ask, “What size air conditioner do I need?”, “Which is the Best AC in India 2023?” You would be surprised to know that buying a device that is too powerful or not powerful enough can result in less than optimal cooling.
While an underpowered unit may simply not work, a high wattage unit will cycle on and off too frequently and will never operate at peak efficiency in cooling your space.
The constant cycles of on and off will also result in improper dehumidification. Use the table below as a rough guide to get you started:

Finding the right size unit should be as easy as looking at the shipping label for any air conditioner. They will tell you, along with the size of the air conditioner, the average square footage it is suitable for. However, there are a few more factors to consider before buying:
General Air Conditioner Sizing Guidelines
Is your insulation adequate, especially on ceilings?
Poor or no insulation will require a block with more BTUs. Strongly consider purchasing and installing appropriate insulation if possible. Make sure your home goes green with this home insulation guide.
Do you have high ceilings? (over 9 feet)
High ceilings mean extra space for cooling. You may need a larger air conditioner with more BTU power.
Will this air conditioner be used to cool an active kitchen, an upstairs room, or a large open plan area?
In these situations, a block with more BTUs may be required.
What condition are your windows in? Do you have many?
The more windows, the greater the cooling loss. Single pane windows lose cooling faster than double pane windows.
Do you keep the curtains closed during the day?
If so, you may be able to use a smaller air conditioner with fewer BTUs.
Does your space face north or east?
These sides of your home tend to be cooler as they are exposed to less intense sunlight – you can use a device with fewer BTUs.
Is your space in question facing south or west?
These sides of your home tend to be warmer as they are exposed to more intense sun exposure – you may need a unit with more BTUs.
Are there any sources of shadow from overhangs or trees?
If so, you may be able to use a block with fewer BTUs.
Will the device itself fit in the window frame or in the space you expect from it?
Generally speaking, the larger the BTU output, the larger the device. You may need to consider a portable air conditioner instead of one that fits in a window.
Do you have the correct power voltage and outlet?
Larger devices may require a 240V outlet.
Specific BTU Size of Central Air Conditioner
Are your air ducts mostly located in the walls or in the attic?
Attic ducts are exposed to the rising heat in your home and should be properly insulated. In this case, it is highly recommended to purchase and install appropriate insulation, if possible.
Are your air ducts tightly sealed with no noticeable leaks?
You don’t need a high BTU device.
AC Energy Star Ratings: What do They Mean?
The Energy Star rating for all air conditioners, whether windowed, portable or central air conditioners, is based on EER.
The Energy Efficiency Rating, or EER, is obtained by dividing the BTU generated per hour by the number of watts consumed during that period at a given temperature level of 95°F.
This is an important indicator of air conditioner performance. The higher this ratio, the better the efficiency of the system. All air conditioners are federally regulated and must meet a minimum EER for a specific BTU output.
Energy Star rated units must be 10% more efficient than the federal minimum, as shown in the table below.
The most efficient systems usually cost more, but they may also qualify for tax credits under state or federal government stimulus programs.
This can help reduce a significant portion of the additional initial cost and usually includes labor costs for installation!
If you’re interested in a sustainable lifestyle, the first step is to make sure your air conditioner is Energy Star rated.
Consumers will also often see SEER or Seasonal Energy Efficiency Rating. This “energy score” more accurately reflects the overall efficiency of the device as it is calculated on a long-term basis.
SEER will also always be higher than EER for any given unit. Essentially, SEER gives you an idea of the overall efficiency of a system, while EER gives you an idea of a device’s performance during periods of peak performance.
Both SEER and EER are important when considering buying an air conditioner, especially when purchasing larger capacity central air conditioners.

For units that also work as a heat pump, you will also see the HSPF or Seasonal Heating Performance Factor. It is simply SEER when the unit is in heating mode.
If you expect to use your heat pump more frequently in cooling mode, look for a unit with a high SEER.
Conversely, if you expect to use your heat pump more frequently in heating mode, look for a unit with a high HSPF.
Keep in mind that if temperatures in your area frequently drop below 40°F, it will probably be more cost effective to cool your space with a central air conditioner in the summer and a stove in the winter instead of a heat pump.
Heat pumps have the added benefit of being installed and maintained as a single unit, but the potential buyer must consider the additional costs typically associated with these units in addition to the extra wear and tear on a year round system.
What’s more, in this colder climate, the heat pump’s external coils can build up ice, effectively forcing the unit to run on air conditioning for a while to melt them.
