Buying Guide: 5,000 BTU ACs
What Size Room Can a 5,000 BTU AC Cool?
The best 5,000 BTU air conditioner can efficiently cool areas of about 100 to 150 square feet. This area coverage estimation comes from the Energy Star air conditioner room sizing guide.
They further state that if your room receives direct sunlight, you should increase the capacity by 10%, bringing a 5,000 BTU unit's coverage area to 95 to 135 square feet.
And if the room you want to cool is in a shaded area, you should decrease the cooling capacity by 10%, so the 5,000 BTU AC will cover areas ranging from 110 to 165 square feet.
The cooling capacity is also affected by the number of people inside the room and the room type. However, such adjustments are not relevant for such a small air conditioning unit.
Features That Matter
Since the range of 5,000 BTU air conditioners is vast and varied, you cannot blindly choose any model.
Although these are low-capacity units, you still have to determine the type of AC, ventilation, noise output, fan speeds, etc. Below we have listed all of them so you can make an informed purchasing decision.
BTUs & Room Size
A 5,000 BTU air conditioner generates 5,000 cooling BTUs per hour. This cooling capacity might seem low, but it is enough to cool small areas measuring 150 square feet.
You can use such a unit to cool an office, closet, kitchen, or small bedroom.
So when you are choosing between different models, make sure to pick the one that can efficiently cool your room. Measuring its size beforehand also enables you to make the right choice.
Type of AC
5,000 BTU ACs come in both portable and window variations. And even these two categories are further divided into subcategories. Have a look:
Window - Horizontal
These models encase both the cooling and exhaust components inside their body, with the cooling vents opening into the room and the exhaust vents facing outside.
They come with mounting brackets and pleated curtains to prevent cool air from escaping outside.
Window - Casement/Sliding/Vertical
These are designed to install over horizontal sliding or casement windows. Since such windows are usually vertical, these ACs also feature a vertical design that easily fits inside the window.
Operation-wise, they are similar to horizontal window ACs with cooling vents on the inside and exhaust vents outside the window.
The portable ACs that need a window or some other opening to vent outside are included in this category.
They come with an exhaust hose on the back and a window kit. The kit installs over a window while the hose attaches to it for venting the heat generated by the system.
Ventless / Evaporative
The ventless or evaporative units use the moisture drawn from the air to keep their system cool.
Since the system uses condensate and no heat is generated, these systems are portable and can be easily used as standalone units.
Size of Unit vs. Size of Window
Whether you choose to purchase a portable AC or a window mounting one, you have to keep the size of your window in mind.
For mounting the unit over it, your window should be big enough to fit the AC through. If it is small, the AC will not fit, and if it is too big, you'll need to think of something to seal the gaps.
Similarly, portable air conditioners also need a window to vent the heat. If your windows have an unconventional design or size, you'll need to factor it in before finalizing your purchase.
Some 5,000 BTU air conditioners come complete with their installation kits; others do not.
The installation kit in window ACs consists of the mounting brackets and frame, while in portable ones, it is the window kit for venting.
Your priority should be an AC that comes with all the installation components. Nobody likes making additional purchases, let alone the entire process of finding compatible components in the first place.
Dual Function (Heat + Cool)
An AC that can cool and heat a room is undoubtedly a must-have. Such a unit keeps your room cool in summer and provides supplemental heat in winter.
While there are not many dual-function AC in the 5,000 BTU range, it is definitely worth your notice if you can find one.
Nobody likes a loud AC. It makes everyday activities like conversing and watching TV very difficult.
If you want to avoid such a situation, look for an AC with a maximum sound output of around 50 decibels.
An AC with multiple fan speed support makes your life easier. You can adjust its cool air output to suit your needs and lower the noise and energy bills.
The energy-saver mode is your key to reduced energy bills. An AC that can operate on energy-saver mode guarantees efficient performance and savings with controlled fan speed and cooling temperature.
Most window ACs feature an exhaust switch that allows the stagnant indoor air to be replaced by fresh one from outside.
It is typically a slider that opens a small window towards the back of the unit. The fresh air from outside is drawn in, cooled down, and circulated into the room from this window.
Almost every AC doubles up as a dehumidifier to draw extra moisture from the air.
While this function is active in the cooling mode, having it separately lets you reduce indoor humidity without investing in a dedicated dehumidifying unit. If you live in a humid area, prioritize this mode of operation.
Being installed in a small 150 square feet room, your AC would not be very far to adjust manually. But with a remote control at hand, you can operate the AC from afar.
Wi-Fi connectivity is a feature present 8n most modern AC. You can sync the device with your home assistant and use voice commands to control its operations with this function.
Similarly, with Wi-Fi connectivity, you can also control the unit from any part of the world with the compatible mobile phone application.
Programmability & Timers
The convenience of programming the AC to turn off and on at desired times is a true blessing.
You can easily adjust such a unit to turn on and off at desired times, so you come to a cool room, and when you leave, the AC automatically turns off.

Installing a window AC unit is not a very difficult task. Many homeowners have been doing it themselves for a while now. Here is how you can install one yourself:
