Costs range widely depending on what is wanted and/or required.
Portable units are the cheapest form of air con, ranging from £350 to £650 on average, depending on the brand and performance, according to Checkatrade., external
However, as demand has soared in recent weeks some retailers began selling the cooling machines for £149, as Lidl did in its infamous middle aisles.
Wall mounted or split air con units can cost between £750 and £1,100 each, Checkatrade says - but that is just the unit, and does not include the labour and other installation costs, such as hooking it up to the property's electricity fuse board. Installation company Heatable suggests, external a full cost is typically £2,000 to £3,500, but can go up to £6,000 if you want to have it in more than one room.
Ducted air con systems cost the most, between £990 and £1,750 without installation costs, according to Checkatrade. Fitting the ducting or remedial work to hide it inside properties means it is likely to be more expensive than any of the other systems given the level of work involved. Heatable estimates it to be between £5,000 and £10,000, depending on the property size, layout and how complex the ductwork needs to be.
The size of both split and ducted units are determined by what is known as the BTU (British Thermal Unit), Checkatrade says, to ensure it will cool the space it's required to. The larger the BTU number, the bigger the room to cool, and therefore the more expensive the unit.
Following installation, consumer group Which? suggests the running costs "vary wildly" and depend on the type of system.
"A typical portable air conditioner adds roughly 25p to 40p an hour to your electricity bill," it says.
Stating the obvious, the main benefit of having air con in a home is that it can keep it cool during times of extreme heat, meaning people can sleep, work and generally live more comfortably.
However, air con units require electricity, the price of which remains much higher now than it was a few years ago, and so you can expect your overall energy bill to increase if you purchase and use one regularly.
Some environmental groups have also raised concerns over the impact of such technology on the environment, including the chemicals used in units to cool air.
Portable air con units are easy to set up, use and move around homes. They are cheaper to buy than the alternatives and do not require professional installation.
But they can be more expensive to run due to not being as energy efficient.
Checkatrade says portable or window units are a good short-term solution and are also ideal for renters or those who live in listed buildings who cannot make major changes to their property.
Split systems are much better at cooling rooms and are also cheaper to run, according to Checkatrade. They are also quieter than portable units, but they do entail larger upfront costs and need to be installed by a professional tradesperson.
Ducting air con is the least noticeable option due to the vents and can cool multiple rooms. But when it comes to retrofitting older homes it can be complex due to having to find space for the equipment, which adds to installation costs.
