Right, let's be honest. British summers have a habit of catching us completely off guard. One minute it's grey and drizzly, and the next you're melting on the sofa wondering how the upstairs bedroom turned into a sauna. June has a particular knack for springing some properly uncomfortable heat on us, and if you don't have air conditioning sorted, things can get pretty grim pretty fast.
The good news? You don't need to splash out on a permanent installation or spend a fortune at the DIY shed. Air conditioner hire is a brilliant, flexible way to get cool on your terms. Whether you're after air con hire for your home, your garage workshop, or your home office, HSS DIY has got the kit to sort you out with next day delivery, ordered online 24/7.
This guide covers everything you need to know about how to hire a portable air conditioner, which unit to go for, how to set it up safely, and whether hiring or buying makes more sense for your situation.
Buy the materials. Hire the tools. One order. All in one place.
Why Hire Rather Than Buy? The Case for Flexible Air Con
A lot of people buy a portable air conditioner on impulse during a heatwave, then spend the next ten months wondering where to shove it. Hiring makes a whole lot more sense for most households, and here's why.
For most UK homes, the summer heat lasts a few uncomfortable weeks rather than all year round. Hiring means you pay for what you actually need, and when it gets collected, it's someone else's storage problem.
Which Cooling Unit Is Right for You?
Not all cooling kit works the same way. Picking the right one makes a real difference. Here's a breakdown of what's available to hire from HSS DIY.
Compact Air Conditioner (3.5kW) - Best for smaller rooms
If you're cooling a single bedroom, home office, or living room up to around 20m2, this compact unit is a solid choice. Plug it in, feed the exhaust hose out of a window, and you're away.

Semi-Industrial Portable Air Conditioner (6.1kW) - Best for larger spaces

Medium Evaporative Cooler - Best for well-ventilated spaces
A brilliant, energy-efficient alternative to traditional air con. An evaporative cooler uses water rather than refrigerants to bring the temperature down, so running costs are much lower. Perfect for workshops, garages, and spaces with decent airflow. Fill the tank, plug it in, and it's cooling within around 20 minutes. Hire from approximately £90 per week.

Air Conditioner vs Evaporative Cooler: What's the Difference?
This is probably the most common question we get, and it's a fair one. Here's the short version.
- Portable air conditioner: Uses refrigerant and a compressor to actively cool the air. Needs an exhaust hose vented outside. More powerful cooling, especially in sealed rooms. Uses more electricity.
- Evaporative cooler: Passes air over water-soaked pads to cool it down. No exhaust hose needed, but works best in well-ventilated spaces. Much more energy efficient. Adds a bit of humidity, which can actually feel refreshing in dry conditions.
If you've got windows you can vent through and want the strongest cooling, go for the air conditioner. If you're in an open workshop or want to keep running costs down, the evaporative cooler is the smart choice.
How to Set Up Your Hired Portable Air Conditioner: Step by Step
Setting up a portable air conditioner is genuinely straightforward. Here's how to do it safely and get the most out of your unit.
- Unbox and position the unit. Place it on a firm, level surface close to a window or external door. Keep at least half a metre of clearance around the unit.
- Attach and route the exhaust hose. Connect the ducting to the rear of the unit and feed the other end out through a window gap or partially open door. Most hire units come with 3m to 9m of ducting.
- Seal any gaps. Tuck a towel or draught excluder around the hose where it exits the window. This stops warm air flooding back in and makes the unit much more effective.
- Plug in and switch on. Connect to a standard 13A socket. Most units have a timer, fan speed control, and temperature setting. Start on the highest fan speed to cool the room quickly, then drop it down.
- For evaporative coolers: fill the tank with water. Position near an open window for best airflow and top up the water regularly, or connect to a hose for continuous use.

Health and Safety: Things to Keep in Mind
Never run the exhaust hose internally or bend it tightly - this can cause the unit to overheat.
Do not run the unit in a completely sealed room without any ventilation.
Keep the power cable away from water and trip hazards.
Do not cover or obstruct the air intake vents.
If using an evaporative cooler, change the water regularly to prevent bacteria build-up.
Keep children and pets away from the unit while it is running.
If the unit makes unusual noises or smells, switch it off and contact HSS DIY.
Case Study: Keeping Cool During a Home Renovation
Project: Full kitchen refit during a hot July fortnight
Location: Semi-detached house, South East England
Challenge: Trades working in a south-facing kitchen with no working ventilation during the hottest weeks of the year
Solution: One compact air conditioner (3.5kW) for the kitchen and a medium evaporative cooler for the open-plan lounge area
Result: The workspace temperature dropped significantly within 20 minutes. Tradespeople stayed comfortable and productive throughout. Both units were collected the day after the project finished - no storage headaches.
This is exactly the kind of scenario where hiring beats buying hands down. Two weeks of hire for a couple of hundred pounds, versus buying units that would then sit in the shed for ten months of the year.

What's the difference between an air conditioner and an evaporative cooler?
