How To Buy The Best portable air conditioner

Looking for the best portable air conditioner? Check out our guide below and you’ll be well-placed to select the correct one for your needs.

Do you have trouble sleeping when it’s too hot outside?

Or do you work in an office where it’s impossible to get anything done because it’s too hot?

In the hot summer months, a portable air conditioner (PAC) can keep a single room cool with no disruption to the home and at a far cheaper cost than house-wide systems.

Most versions have a built-in timer, which means they only turn on when you’re in the room and don’t waste energy.

With some restrictions, you can even move them around, so the same unit that cools your home office during the day can also keep your bedroom cool at night.

What factors should you consider while selecting a portable air conditioner?

I’m not sure how much I’ll need to spend.

PACs aren’t cheap: the majority cost between £300 and £1,000.

Evaporative air coolers are more common below this price point than genuine air conditioners, which are less effective.

The amount you’ll need to spend is determined by your cooling needs.

The amount of heat required to raise the temperature of one pound of water by one degree is measured in British thermal units (BTU).

A higher rating indicates that the air conditioner can cool a larger area, implying that the unit will be larger and more expensive.

A 9,000BTU unit can heat up to 45 cubic metres of space, while a 12,000BTU unit can heat up to 90 cubic metres.
Before you go out and get an air conditioner, make sure you measure your space to ensure you get the right one.

Of course, you don’t want to go any larger than necessary.

Weight, size, and convenience all matter, and if a unit is too huge, too heavy, or too difficult to put up, you may find yourself only utilising it on a few very hot summer days.

You must weigh the cooling power you require against the size and intrusiveness of a PAC before you are unwilling to put up with it.

What is the best location for a portable air conditioner?

Another consideration is location: most PACs must vent hot air through a window, and if you can’t put it exactly next to one, you’ll either have to install a permanent vent in the wall or look for a type with a hose extension.

Furthermore, as the air escapes, more warm air has the opportunity to enter.

In fact, the air conditioner’s negative air pressure actively encourages it to do so.

A window fastening kit is included with most PACs to close any gaps, but it may only be suited for a sash window, sliding door, or hinged top window.

While you might be able to make do with hardboard or towels, it’s a good idea to double-check your alternatives for your chosen PAC before you get it home.

Your air conditioner is required to evacuate more than just hot air.

Moisture condenses when the air cools, and this is collected inside the PAC.

Some types may evaporate this internally and exhaust it through the hose or the rear of the unit, while others keep it in an internal reservoir that must be manually emptied.

Will a portable air conditioner be noisy and expensive to operate?

Because all PACs have a compressor and one or more fans, they will never be completely silent.

However, some are quieter than others; the manufacturer’s specification should indicate the lowest and/or maximum noise pressure levels.

Also keep an eye out for sleep modes.

To make the PAC’s hum a little easier to sleep through, they turn off the compressor and lessen the speed of any fans.
If you’re having trouble sleeping because of the noise, consider cooling the room before going to bed, or using a desktop or pedestal fan instead.

When it comes to operating costs, a higher BTU rating means the PAC will do more work and consume more energy, but not all units are made equal.

Like your fridge or oven, your air conditioner should have an energy efficiency class ranging from A++ to G.

The more efficient the unit is, the higher the letter rating.

Are there any additional characteristics I should be on the lookout for?

PACs, like most large appliances, have an environmental cost.

Choose an energy-efficient A++ model to help cut down on this, but some manufacturers are also enhancing their green credentials by using refrigerant gases like R290, which have a smaller environmental impact and don’t produce greenhouse gases over the product lifecycle.

At the end of each summer season, PACs should be emptied and cleaned, and easily accessible fans and filters make the process a lot easier.

Make careful to clear up any pipes or drains as well; if left alone for a long time, they may get rather nasty.
