What Is a Window Air Conditioner?

A window air conditioner is a simple cooling system with all the necessary components and parts placed inside a box. This unit is similar to the traditional wall air conditioners, with the only difference being that it is more technologically advanced. The unit is plugged into an electric outlet inside the house while an exhaust hose discharges water outside the house.

Modern window air conditioners are lighter than old school units and can be transferred from one window to another when the need arises. They work independently of HVAC systems and can cool one or two rooms at once but not more. You can install it permanently inside your window or inside a standard vertical sash. It can also be installed inside a wall.

A window air conditioner has three major parts, which are

• Evaporator coil

• Condenser

• Compressor

Besides these three major parts, it also has motorized fans, an air filter, expansion valve, control panel, and a manual or digital thermostat. Then there is a special chemical compound that absorbs the heat from the room while the condenser transforms the hot air into cold air for onward release back onto the room. Window Air conditioners can be used in homes, libraries, dorm rooms, RVs, and offices.

How Do Window Air Conditioners work?

The mode of operation of a window air conditioner is not very different from that of any other cooling unit. This system simply removes humidity and heat from the room while circulating cool air back in its place. The basic components that cool the air include the refrigeration tube filled with refrigerant, fan, thermostat, condenser coil, and evaporator coil.

When the temperature in your room rises and becomes very hot, this heat level triggers the thermostat in the unit. Once triggered, it activates the blower, which draws the hot air in the room into the system that is transferred to the refrigeration coil. As air passes through the coil, it is cooled, and from there, the cold air is pushed back into the room: the more cold air that is released, the more temperature drops.

Also, note that window air conditioners use two air cycles. The interior unit uses one fan to blow the air all over the evaporator coil to cool the room, while the exterior unit blows the condenser with a fan to cool it down. That is why window air conditioners mostly have two fans.

The design idea of this cooking system is to move air in and out consistently. That is the air in the room into the air conditioner and drawn air our through the air vents. And as we pointed out, once the air in the thermostat is activated, the unit starts working with the fan kickstarting the process, which is followed by the compressor.

You should also note that the air that is drawn in also passes through an air filter that filters the air of unwanted dust and particles. The dust and particles are trapped in the filter while the air is released into the evaporator coil.

Since the coil has a temperature that is much lower than the room air it receives, the coil Simply absorbs the heat, causing the air temperature to drop. This air is called chilling air. Another fascinating thing about this technology is that the cooling coil’s temperature drop causes dew to form on the surface. Also, it removes moisture from the air to reduce humidity.

So as the process continues, the room temperature will continue to drop until the interior air becomes very cold.

What Are the Benefits of a Window Air Conditioner?

A window air conditioner is one of the most common air conditioners in use today. You will find it in many homes and offices, including libraries. Some campers also install them in their RVs because of their functionality. Here are some of the benefits of installing a window air conditioner in your workspace or home.

1. Affordable

Window air conditioners are relatively cheap compared to the other units on sale today. Their affordability makes them an attractive unit for low income earners or people who want to minimize their running costs. How much you pay for the unit will depend on the brand but not only that, the capacity of the unit will also influence the price.

Units with a higher BTU rate and special features will cost more than units with lower rates and fewer features. 5000 BTU units cost less than 8000 BTU units and above. Smart units that are app-controlled and respond to voice commands cost more than units that are remote-controlled.

2. Amazing features

Unlike the old school window air conditioners with basic features that were cumbersome to operate, this one has several features. Many manufacturers include an auto-restart function that will revert to previous settings in case there is a power interruption. There is also a sleep mode there reduces air output and tones down the noise level. What about the special air vents that swing from one direction to the other, sending cold air to every part of the room?

All these amazing features make window air conditioners a top draw for many homeowners.

3. Power-efficient

Modern window air conditioners are efficient and do not consume too much energy. Contrary to popular opinion that this cooling system consumes so much power, it will interest you to know that this is not true. Most of them have Energy Efficiency Ratio (EER) that analyses your power consumption by the minute. There are also energy star units that consume less power than traditional air conditioners or HVAC systems. If you notice that your central cooling system consumes too much power, you should consider going for a window air conditioner.

4. Easy installation

Gone are the days when you had to rely on an expert to help you with your AC installation. Today, there are window systems that you can install on your own. These systems come with window installation kits and an instruction manual that will guide you on how to install the unit. No special tools or knowledge is required to install it, and you can do it in less than 30 minutes.

5. Free your floors

Since they are window units, your floor will remain free and not clog your living space. This is the unit of choice for small rooms. With the unit sitting on your window, you have enough ground space to place other items or leave free. And as you know, a spacious room is far more welcoming than a clogged one.

How to Choose a Window Air Conditioner?

To conclude this buying review, it is imperative that we furnish you with a buying guide when selecting a window air conditioner for your home or office. We know that there are so many brands today there promise buyers value for money, but we do know that some of them are not as good as their sellers claim.

So to ensure that you buy a unit that offers value for money, here are the things to consider when choosing a window air conditioner

1. Energy Efficiency

How efficient is the unit? Does it have an efficiency seal? This is something not to overlook because the price you pay for the unit is not the only cost you will bear. You will also have to bear running electricity costs, so if it consumes too much power, you may end up spending 20 times its value in energy bills during the life span of the unit.

When evaluating energy ratings, look for one of two seals. First is an Energy Star seal which indicates that the air conditioner consumes at least 10% lesser than conventional units. Another seal to look out for is one with multiple energy efficiency ratio, which also signifies a drop in power consumption. A 0.1 increase in EER eating means a 1% drop in electricity usage.

2. Capacity

Another important thing to consider is the capacity of the window air conditioner. These systems are measured in British Therma Units (BTU). To be sure that the unit will be right for you, first determine what your cooling needs will be. Then search for a system that will meet that need. For small rooms between 150-200 square feet, a 5000 BTU window air conditioner will suffice. Medium-sized rooms of 250-500 square feet, you will need at least between 6000 BTU – and 8000 BTU. For much larger rooms, we recommend units of 10000 BTU and above.

The best way to determine your cooling needs is to consider the ceiling height, access to sunlight, and the maximum number of occupants you will have in the room at any point in time.

3. Type of installation

How would you like to install the unit? Although it is called a window air conditioner, it can also be installed on a wall. If you only have a single window in the room and you don’t want to prevent natural air from coming in, you should consider buying a unit that can be installed in the walls. Luckily for you, some units can be installed in windows and walls. But to be sure, read the description first before making a final decision.

4. Power requirements

What are the power requirements of the system? This is another thing to consider. The power requirement should not be confused with the energy efficiency as they mean two different things. While the latter is about the power consumption, the former is the electric installation need of the unit.

Most window air conditioners work with 115 volts, 125 volts, or 220-volt circuits. If the air conditioner runs below 15000 BTU, it will most likely run on 115 or 125 volts. For larger units above 15000 BTU, the voltage will be 220 volts. So if you don’t have the voltage for the unit, this should not discourage you from buying it since you can hire an electrician to fix your wiring.

5. Noise level

You should also consider the noise level. Does it make so much noise when it is working, or does it make less noise? Units that make so much noise will disturb your peace, especially at night when the world is quiet around you. So we recommend units bow 50dB. dB stands for decibel level, and the higher the dB rate, the more noise the air conditioner will make.

6. Check your space

You want to check the space in your window before buying the window air conditioner. Will your window fit it? Will you have to change the window, or will it fit right in? The last thing you want is to have to break and readjust your window because you want to fit an AC in. Breaking your window will cost you more effort and resources that you don’t want to expend. So make sure you measure your window and compare it to the size of the air conditioner before you buy it.

7. Air filter

The quality of the air filter also matters. Very good air filters last very long before they go bad, and that is what you should be looking for. You also want to make sure that the unit’s filter is easily available in the market; otherwise, you will have difficulty finding a replacement. Very good filters trap dust and particles and ensure the smooth release of clean air. If you are allergic to dust and pollen, you want to take this feature seriously.

8. Intelligent cooling function

Some window air conditioners have smart, intelligent cooling functions that you can adjust with your smartphone or by issuing voice commands. This feature works in a Wifi network, and they are easy to control. If you prefer this type of window air conditioner, be prepared to pay more for it, though.

9. Warranty

Last but not least is to check the manufacturer’s warranty. To secure your investment, we recommend an air conditioner with a longer warranty of at least a year and above. In case the unit develops a fault, you can return it and request another if the unit falls in line with the manufacturer’s policy.

Window Air Conditioner FAQs

1. How to Install Window Air Conditioner?

To install a window air conditioner, you need to find a window close to an electric outlet. The distance between the spot you choose and the outlet should not be more than 6ft. Once you’ve picked a spot, you have to arrange the tools you need, which are a screwdriver, measuring tape, scissors, the unit’s bracket, and screws.

• Remove the AC and place it in the center of your window. To maintain a proper spot, mark the window’s width with a pencil and ensure the spaces are even on both sides.
• Open the window and remove the weatherstrip from the unit. Strips are put in place to block air. If your unit does not have one, then it means it doesn’t require one to function, so you shouldn’t bother.
• Attach the panels in their appropriate spots and secure them with the screws provided. Then connect all the screws to close any gaps so air, allergens, and pollution do not enter your home.
• Now insert the window air conditioner into the window, then close the window from the top.
• Install the L brackets to secure the finishing

Start by cleaning the filter. Unplug the unit from the power socket, then take off the front panel to access the filter. It will most likely be covered with dust so use your vacuum or dry cloth to remove the dust. Wash it with warm water and soap, then set aside to dry. Once dry, fix it back, and you will continue to enjoy clean air. Filters should be replaced twice a year and cleaned every month.

Clean the exterior

The exterior also needs cleaning, so you need to do a perfect job. Wash the grill to remove stains and dust, or you may use a damp cloth to clean it. Concentrate on areas with air gaps. Now focus on the side and tops of the unit. Note that the unit should be turned off when you are cleaning it.

Clean coils and fins

The coils and fins should not be left out. These are inside the unit, so you need to be very careful. Use the soft brush to comb the fins carefully to remove dust and debris, then progress to the fins. After dusting both, blow a can or bag of condensed air into the coils and fins to dislodge leftover dust inside the coils.

Clean the tray and drain

The drip may have wastewater in it, which you need to dispose of. Clean out any droppings or dust in the tray and leave it to dry before replacing it. Lastly, check the drain to ensure nothing is blocking it.

Spray after reassembling

After reassembling the unit, take your time to spray it with Hydrogen Peroxide. This will prevent the growth and spread of mildew.

Window air conditioners can be very noisy when they are working, but there are some things you can do to reduce the noise output. Many users try one or more of these tricks, and they work perfectly well. Here are some helpful ways to make your window air conditioner less noisy.

Examine your installation: Is your installation done correctly, and is the unit secure in the window? If it is not, it will keep vibrating when it is one, and this will make you and other occupants uncomfortable. So tighten any moving parts.

Check the panels: You should also check the panels to see if it is loose. If they are loose, use a screwdriver to tighten the screws.

Examine the fan: Another source of noise may be the fan. Is it crooked or bent? If it is, it will make noise. One common cause of a bent blade is that it may be hitting another component in the unit. So may sure the fan blade is free of any obstruction. Straighten it if you must and dust it.

Cons: Window Air conditioners require installation and, in some cases, window alterations. Furthermore, they consume more power and generate a lot of wastewater.

Portable air conditioners, on the other hand, cannot cool rooms as well as window systems, but they are lighter and can be moved from room to room.

Conclusion

The best window air conditioner will provide you with maximum cooling without raising your energy bills. All the systems reviewed this far represent value for money. If you want a device that is suitable for dorm rooms, we recommend Amazon Basics. For a system with multiple user modes, Homelabs trounces all others. If energy efficiency is a priority, consider LG Energy Star.
