What You Should Know Before Buying a Small AC Unit

Since you want to buy the best small AC unit, you will check for a few features before spending your hard-earned cash.

This section will walk you through some of the features to check for when buying a small AC unit for your room. When sourcing a small AC unit for your bedroom, office, or other rooms, you want to check for the following features:

Cooling Power

Before buying a small AC unit, you want to check if it cools your room with sufficient power. However, the cooling power is not in Watts as many people think.

The cooling power of a small AC unit is in BTU. The more cooling power a small air conditioner boasts in BTU, the more powerful the unit is.

So, you want to choose an air conditioner with more BTUs if you want faster and more powerful cooling performance.

But more cooling power comes at a cost since your unit will use more electricity. If you want powerful performance but don’t mind the high electricity bills, you should buy a small AC unit with more cooling power in BTU

. Your room will achieve your ideal comfort in a short time, unlike what you’d have with a less powerful small AC unit.

The Number of Functions

Even though your goal is to achieve the perfect temperature for a comfortable home, you still want a small AC unit that performs other functions.

Your small AC unit could also dehumidify your room and perform the function of a fan. Such a small air conditioner is multi-functional.

When buying a small AC unit, you want to check if it performs other functions. The dehumidifier function ensures your room has no excess moisture that could affect your respiratory health and eyes.

When the moisture level in the air is within the acceptable level, you will comfortably breathe. As such, you want to ensure your preferred small AC unit also features a dehumidifier function.

The fan allows your unit to circulate the air within the room. As a result, your room will have a comfortable atmosphere in a short time.

Therefore, you want to ensure this function is also in your preferred small AC unit.

The Room Size

A small AC unit only serves a room and not the entire home. But these climate control devices can keep a given room space comfortable.

That means they have limits since they might not keep larger rooms comfortable. As such, you want to check the room size in square feet a small air conditioner unit can heat.

The good news is these AC units indicated the rated room size.

Before buying one AC unit, you want to check your room size. Then you will buy a small AC unit capable of cooling that room.

If you want to cool your bedroom and it’s 350 square feet large, you want to buy a unit rated for such spacious rooms. If your bedroom is more spacious, you should consider buying a small AC for larger rooms.

Check the rated room size, then buy a unit that cools your preferred room.

Control

Small AC units also feature controls for adjusting their functions, such as the dehumidifier and fan. Some units feature a control panel with touch buttons for adjusting the functions.

On the other hand, some units include a remote control for more convenient usage.

A small AC unit with remote control is convenient to control. You can press the buttons on the remote control to control your air conditioner without touching it.

This is essential if you’re far from your AC unit for some reason. If you want unmatched control efficiency, you should consider buying small AC units featuring remote controls.

The Noise Level

Small AC units feature electric motors for their fan functioning. The motor is essential to spin the fan for circulating air within your room. But the spinning fan produces some noise, and there is little you can do.

One of the little things you can do includes checking for a small AC unit producing less noise.

If you want to use your small AC unit in your bedroom, office, or study room, you want a unit producing less noise. Any air conditioner unit producing less than 50 decibels is quiet enough for use in bedrooms and offices.

So, consider buying small AC units producing no more than 50 dBA for peaceful and quiet cooling performance.

Ease of Installation

Installation is also a factor to consider before buying a small AC unit. The ease of installation depends on the design of these air-cooling devices.

A small AC unit with a simple plug-in design is easy to install – you only have to plug it into a wall outlet, and it will be running.

Some units even include window kits for installing them on your window. They include a user manual to help you every step of the way.

You can also find other small AC units with rolling wheels that allow you to set them up on your floor. There are various designs on the market, and each design has its benefits.

If you prefer plug-in small ACs because they are easier to install, you should consider buying them.

But if you love hands-on projects, you can buy a unit with a window kit for a DIY project. You should choose the design that makes installation work easier for you.

This will ensure your unit runs as soon as you get it in your loving home!

Weight and Portability

Small AC units are portable since they weigh fewer pounds. But they vary across the board since they feature different designs. You can find some units weighing more pounds than others.

And that means portability varies. If you want a portable small AC unit, ensure you buy an air conditioner weighing fewer pounds.

You can keep it below 60 pounds for impressive portability.

But portability depends on one more thing: transportation wheels. A small AC unit with transportation wheels is easier to move across the floor.

Therefore, consider buying an air conditioner weighing fewer pounds and has transportation wheels.

Price Of the AC Unit

This doesn’t only apply to small AC units; it applies to anything you set your mind to buying. Before you spend your hard-earned cash on a small AC unit, you want to check its price.

Buying an air conditioner is an investment like any other, and you want returns. As such, you want to spend a considerable amount.

You don’t have to break the bank to get the best small AC unit for your room. And that’s one good thing about these air conditioning units – they cost less than central air conditioners.

Despite costing less, they deliver incredible cooling performance. Of course, price varies across the board, with some units costing more.

Each investment has a budget, and you want to check the price of a small AC unit to allocate the correct amount of cash.

FAQs

How much room size does a small AC unit cool?

Small AC units are perfect for single rooms. They could keep your bedroom comfortably cool. Also, your air conditioner could keep your office or study room comfortable.

Generally, small ACs keep rooms of up to 350 square feet cool and comfortable. 

But more powerful small AC units could keep a 550 sq ft. room cool. If your room is more spacious, you want to get a small AC with incredible BTU output.

You should consider over 10,000 BTUs of cooling power for larger bedrooms.

How much electricity does my window AC consume?

Window AC units differ in design. That means they cool rooms using different cooling power. More powerful units consume more electricity.

But these air conditioning devices generally consume 500W – 1500W of electricity. Of course, this power consumption depends on the design.

If you choose a window AC unit with an incredible cooling power of 12,000 BTU, you will be sure your unit will consume more electricity than a model churning out only 4,000 BTU cooling power.

Performance affects electrical consumption. If you don’t have a large room, you should buy a unit producing the required cooling power since anything excess will result in more electricity consumption.

How many functions can a small AC unit perform?

One advantage of small AC units is they are multi-functional – they perform many functions. But their multi-functionality varies across the board. Some units perform more functions than other AC units.

Generally speaking, small ACs have at least three functions: cooling, dehumidifying, and fan. You can find some AC models featuring a few more functions.

When buying a unit from the market, you want to buy one with as many functions as possible. If you find a 3-in-1 small AC unit, you want to buy it since it cools your room, removes moisture, and fans the room.

You should always buy a unit with more functions for usage versatility.

Wrap Up

If you want to keep your bedroom, living room, study room, or other rooms cool and comfortable, you can use a small AC unit.

Even though they cost a few hundred bucks, small AC units bring the comfort you need to any room you install them in. They are multi-functional to cool your room, eliminate excess vapor, and fan the whole area.

Installing them is also a no-brainer. As such, they are worth the investment if you have no central air conditioner.

Our round-up list of the best small AC units narrows down the choices for you. So, all that’s remaining is for you to find the best small AC unit for keeping your bedroom cool and comfortable.
