Solutions for Staying Cool or Keeping Toasty
Most of our cooling systems do more than just chill the air; they come with built-in temperature control. So, whether you’re looking to cool down, warm up, or just improve airflow, you’re all set.
Our smart control systems help your unit run efficiently, only using energy when needed. That means a smaller carbon footprint, and a smaller energy bill.
Air Conditioning in a Nutshell
Here’s a quick lowdown on how air conditioning works, minus the tech jargon.
At its core, an air conditioning unit moves heat around using a chemical refrigerant. It all runs through four key parts: the compressor, condenser, expansion valve, and evaporator.
The compressor pressurises the refrigerant, turning it into a hot gas. That gas flows into the condenser (a long coil) where it cools down and becomes a liquid. The expansion valve then drops the pressure even further, sending it to the evaporator.
In the evaporator, the liquid turns into a gas again. This transformation draws heat from the air, cooling it down. A fan then blows that freshly cooled air into the room. That’s the cycle in a nutshell.
What About Heat?
Just by adding a reversing valve, the process flips. Now instead of sending warm air out, the unit brings it in. The refrigerant flows the opposite way, turning your air conditioning unit into an efficient heater. Smart, simple, and effective.
Whether you’re staying cool or warming up, Cool-Tec’s expert team is ready to help.






Air Conditioning FAQs
I’m interested in having air conditioning installed, do you charge for the initial consultation?
We never charge for initial call out and survey. Our experienced and knowledgeable project managers would love to come and discuss your requirements, and answer any questions you may have.
Why should I invest in air conditioning when I live in the UK?
Air conditioning units aren’t just about the cooling – they can heat your home, too, helping you to create the perfect environment.
Technically advanced, air conditioning units heat and cool efficiently, and – for the gadget lovers –even allow you to control the temperature via a smartphone.
I’m concerned about the appearance of air conditioning units. Aren’t they ugly?
These days, air conditioning units can look as sleek and modern as you’d like. In fact, we think some of them are pretty beautiful to look at (and that’s not just because we love air conditioning!).
And if you’re concerned about the appearance of your external unit, we’d be happy to recommend the best position to blend it in with its surroundings.
Can you build me a bespoke air conditioning system?
We most definitely can! Give us a call on 0800 0189 941 to speak to one of our experienced project managers. They’ll be able to come out, carry out a free survey, and talk to you about what you would like from your air conditioning installation.
They’ll then work with you to design a bespoke system that matches your exact needs and expectations!
How often should I have my air conditioning system professionally serviced and maintained?
We recommend that you have your air conditioning system serviced once a year. It’s far better for your pocket to catch a potential issue before it has a chance to happen – which means it may be worth you having your system maintained and serviced more than once a year if you use your system often.
Get in touch with the Cool-Tec team on 0800 0189 941 and one of our friendly project managers will be more than happy to advise!
Does air conditioning make you ill?
Air conditioning systems and HVAC (heating, ventilation, and air conditioning) systems in general are used to maintain indoor temperature. As part of this process, they’re constantly replacing stagnant air in the room with fresh air from outside, which means they can help to reduce the spread of germs.
If you’re looking at air conditioning to reduce the spread of Covid-19 and other illnesses, remember to keep the air recirculation settings on your new air conditioning unit as low as possible, to ensure the air in the room is constantly replaced with fresh air, rather than being reused.
It’s important that you keep your air conditioning system regularly maintained and serviced to ensure it’s working effectively as possible.
What are air conditioning running costs?
According to research, one air conditioning unit typically costs 44p per hour to run.
