Stay AHEAD of the heatwave!
In 2026, our summer was record breaking. We endured a relentless heatwave with temperature peaking at 38.1°C in Kew Gardens, London… So if you want to remain cool and prepared for when temperatures peak, it’s best to book ahead and get the installation done, before summer hits.
Why? Because HVAC specialists are more readily available and as it’s off peak, you may even be able to get discounted prices compared to the summer rush.

Cooling & HEATING
It’s not just cooling you can look forward to. In the UK. almost all modern day air con split systems will come with the ability to heat to. This is due to them using a reversible air-to-air heat pump feature. It’s a simple heat transference, rather than generating the heat itself. and means that in one complete system, you get a HVAC unit equipped for the scorching summers as well as the chilly winters.
No ductwork needed!
They’re often called a ductless mini-split. These split ac-systems get rid of the need for the traditional bulky ductwork. Instead, a small three-inch hole is drilled to connect indoor and outdoor units.
Modern interactivity
Most of the modern units will have built in Wi-fi. This is perfect for changing temperature using your smartphone or even voice commands like Google Assistant or the Amazon Alexa.
Portable AC benefits
However, split systems aren’t your only choice. You may opt for the Portable AC to cool down. Though they can’t be used for heating purposes, they do have some distinct advantages and may be a better option if you require a temporary cooling solution.
No professionals needed
These systems are designed to be used at home, without the need for professional installation – just simply vent the exhaust hose through a window.
Perfect for temporary residents
If you rent and can’t install a permanent split AC, then this would be ideal for you.
Maneuverability
You can move these systems to whatever room you need cooling in your building or home.
Affordability
They are far cheaper to install than a split air conditioner, so if you’re seeking relief for just intense heatwaves, then this is a more affordable solution. If you don’t want to purchase one of these units outright, then you can choose to hire a portable AC unit for a day or longer instead.
Portable AC limitations
It’s worth noting that, compared to a split AC, the portable AC is not as effective at cooling. This is because a split systems will dump the heat outside of your home completely, whereas a portable unit will still have the hottest part of the machine inside the room. The hot engine of the unit is still in your room whereas for a split AC, it will sit on the outside (exterior wall).
You will also need to make sure that there is proper venting by using an exhaust hose through a window.
Overall, which one should I go for?
If you have a small office or just need your home cooling during an intense summer in England, then a portable A is your cheaper short-term option.
However, for those that want a long-term solution to cooling, with greater energy efficiency and more effective cooling, then a split AC system is a must. Not only will you be receiving the cooling benefits, you have a system that’s capable of heating in the winter.
