Things to Consider When Buying a Portable Air Conditioner

Not sure which portable air conditioner suits your needs? Below, we’ve outlined all of the essential factors and features to look out for when considering the best portable air conditioners available. Take a look at our buying guide and keep in mind these determining factors to help you decide during your buying process.

Size

While a portable AC isn’t as big as other air conditioners, you still want to consider the dimensions. The last thing you want is for a bulky, portable AC unit taking up half of your spare space in your living area. You may also want to consider if you plan on moving the air conditioner from one location to another. In which case, it needs to be lightweight enough that you can reasonably pick it up on your own. The majority of portable air conditioners include wheels to make them easy to transport to different locations.

However, if you don’t plan to move your air conditioning unit into different rooms, you’ll still need to take measurements to ensure that it can easily fit into the room you want to use it for. While some people might be happy to re-arrange their room to accommodate a new unit, is this something that you’d be happy with?

Room Size

While the unit’s size isn’t an absolute determining factor, the size of the space it can cool most certainly is. Most portable air conditioners are unable to cool an entire flat or house and are designed for specific rooms, so you’ll need to research what capacity you need. Fortunately, manufacturers make this fairly easy by using a measurement tool: British Thermal Units (BTU). Some companies may also specify the room size that it’s suitable for, but it’s best to know the exact British Thermal Unit you need.

On average, a 150 sq. ft room will require 5,000 BTUs. A medium-sized room (300 sq. ft.) requires 7,000 BTUs. Or, if you have a space between 350 sq. ft. and 550 sq. ft., you’ll need at least 8,000–12,000 BTU. The higher the BTU, the bigger the unit, the more applicable it is for larger spaces.

With that being said, keep in mind that several factors can affect how the air conditioning unit operates. For example, if your living room receives a lot of sunlight during the afternoon or there are several hot appliances in one room, it might be worth increasing the BTU rating to accommodate these influences.

Energy Use

With anything electrical, it’ll cost you money to power the unit. But, ideally, you’ll consider the most energy-efficient conditioning unit you can buy. To assist you, Energy Star provides a handy directory of the unit’s rating to make it easier to compare the energy efficiency of various models.

If preserving energy is an absolute necessity for you, consider portable air conditioners with a programmable thermostat so that it automatically powers off once the room reaches the acquired temperature. You may also want to choose an air conditioner with an A+ rating for the ultimate efficiency and to keep your energy costs down.

Noise

Nobody wants a loud air conditioning unit, but a lower volume is more important for some people than others. In particular, if you plan on using your air conditioner at night, consider a model with a Sleep mode for a lower amount of power to remain quieter in operation. If a quiet unit is essential to prevent disturbances in your household or office, look for ones with a volume below 52 dBA. Anything louder than this, and you might encounter some disturbance.

Multi-Functional Features

Is it important to you that your unit goes beyond just cooling a room? Many of the best portable air conditioners include several modes, including dehumidifying and even heating. By dehumidifying your home, the appliance can remove moisture from the air to prevent a build-up of mould.  

A multi-functional air conditioner is ideal for use all year round and keeps your home in tip-top condition.

Exhaust Hose Options

Another factor to look into is the exhaust hose options of your chosen air conditioner. Portable AC units come with either a single hose or a dual hose exhaust option. Those with a single hose extract air from the room and release warm air and moisture using the same pipe. This process means that the unit has to work harder to cool down the room, making it more expensive to run and not sufficient for small areas. 

Alternatively, portable air conditioners with a dual hose opinion pull air out of the room with one hose and expel the warm air outside. This option is ideal for cooling down larger spaces in a quicker amount of time.

How to Maintain Portable Air Conditioners

Once you’re happy with the unit you’ve chosen, it’s time to crack down and research how to properly care for the appliance to keep it running.

Clean Filters

Anything that cleans needs cleaning itself. It’s important to get into a good routine of removing any filters in the unit. Most times, these will need to be replaced rather than simply cleaned, but you should check the manufacturer’s advice before making this decision. If you need to replace them, consider buying filters in bulk so that you always have them readily available.

Wipe the Exterior

A dirty portable air conditioner doesn’t look presentable in your home. Keep it looking its best by regularly wiping down the exterior with a soft, damp cloth. Wiping the unit on a regular basis is a lot less strenuous than a deep clean a couple of times a year. Avoid using any harsh cleaning products that could damage the surface. Always ensure that the appliance is properly switched off before you clean it.

Furthermore, move the unit around to check that there’s no leakage or build-up of residue surrounding it. We also recommend getting into a good habit of moving it to another position when you’re vacuuming to keep it spick and span. 

Maintain Condenser Coils

Portable air con units can only produce cold air if they’re in tip-top condition. A crucial part of ensuring that yours is up to standard is by maintaining the condenser coils. Over time, these coils can get dirt and build up with grease and grime. Therefore, you should examine portable units for gunk and invest in a coil cleaner to remove any build-up. Keeping on top of maintenance can save you a lot of money and hassle down the line.

Store Portable Air Conditioners Properly

Another way to keep your portable air conditioner in excellent condition is by storing it properly. When you’re not using the unit, don’t leave it neglected next to a window. Instead, store it in a dry, secure location that’s away from fluctuating temperatures and direct sunlight. 

Leaving portable units plugged in when they’re not running can cause moisture from temperature changes to collect on the unit, not to mention a build-up of dust and dirt accumulated from the room. These contributions can impact the unit’s durability.

A great way to store your unit is to wrap it in a large plastic sheet that covers the entire appliance. A storage closet makes an excellent place to keep it in hiding until summer arrives. This location doesn’t usually have fluctuations in temperature, making it ideal.
