Air Conditioning Frequently Asked Questions

General Air Conditioning Questions

Q: “Which air conditioning unit is best?”

A: There are a lot of options when it comes to finding the right air conditioning system for your property. The best one depends on your needs and the type of unit you can install.

Here at Urban Cooling, we’ll take you through the different options available whether you need a solution for a residential, commercial, leisure or retail property, so you get the right fit.

Q:“Will air conditioning reduce humidity?”

A: Yes, our air conditioning systems can help to reduce humidity in your property. Not only does water-cooled air conditioning blow cool air into your property, it also removes heat and humidity by passing the air through cooling coils. This helps to extra moisture from the air so it doesn’t feel so humid. 

Q: “Are air conditioning systems expensive to run?”

A: Modern air conditioning costs far less to run than people think because they are much more energy-efficient. Our internal water-cooled air conditioning system, for example, is rated AAA for energy efficiency. 

This means that it can cost an estimated 14p-30p an hour to run, depending on the outside temperature, how big a room you are cooling and a few other factors. 

Q: “Are air conditioning units covered by house insurance?”

A: This depends on your insurance. You may need to add your air conditioning unit to your home insurance so it’s covered by named instances. If in doubt, contact your insurer to find out if your AC is covered or if you need to increase your premium to cover it. 

Q: “What is the best temperature to set air conditioning to?”

A: There’s a lot of personal preference that can inform the right temperature for your air conditioning unit. However, 25 degrees centigrade tends to give you a good balance between comfort and energy savings. 

It’s definitely worth adjusting your system to find what works best for you. 

Q: “Can you have air conditioning in listed buildings?”

A: Yes – internal air conditioning systems that don’t require external units can be used in listed buildings. You don’t need planning permission with this type of air conditioning, meaning you can have a system installed quickly and with no fuss.

Q: “Can air conditioning make you ill?”

A: It is a huge myth that air conditioning can make you ill or cause you to catch a cold. Not only can air conditioning not chill you enough to get ill, but it is also likely to help improve your health. 

Q: “Will air conditioning improve the air quality of my home?”

A: At Urban Cooling, we use a charcoal air filtration system, which purifies the air and reduces dust, bacteria, moisture and pathogens that can all lead to illness. You can find out more about the health benefits of air conditioning here.

Water-Cooled Air Conditioning FAQs

Q: “Do you need to modify the property’s exterior during installation?”

A: Our fully internal water-cooled system doesn’t require an external unit or any modifications to the property’s exterior at all.

Q: “Is this air conditioning system loud?”

A: We’re proud to say that our units are the quietest on the market and our indoor units operate at a sound level that is as quiet as a whisper. 

Our condensers operate at around 49 decibels, which is similar to a quiet washing machine. However, they can be installed in a cupboard to hide the noise or an acoustic jacket can be used over the unit.

Q: “How many rooms can one condenser keep cool?”

A: We have a wide range of condensers that can supply between one and eight indoor units with cool & purified air. That means our most powerful condenser can cool eight rooms at once!

Q: “How easy is it to use and control the unit?”

A: Our air conditioning systems can be controlled by an infrared remote or via our app anywhere with WiFi. Set a temperature for the system to cool the rooms to and it will automatically switch off when it reaches that setpoint.

Q: “How long does it take to install?”

A: From your first enquiry, you can have a cool and comfortable property in just 7 days. Installation takes typically 1-2 days per indoor unit.

Q: “Does your system come with a warranty?”

A: We offer a 5-year warranty on parts and repairs for our fully internal unit, so apart from the yearly service, there will be no additional costs to you. Read more about our maintenance and warranty.

Q: “How energy-efficient are the internal units?”

A: With new inverter technology, our internal water-cooled air conditioning system is rated AAA for electrical energy efficiency. This means it won’t cause your electricity bill to sky-rocket and is cheaper to run than most portable AC options.

Q: “Does this system increase the air quality of my home?”

A: Our indoor units are supplied with a washable air filter that purifies the air, reducing the levels of dust, moisture, bacteria and pathogens. This creates a healthier environment for those with asthma, respiratory issues, allergies and hay fever. 

It also means you won’t have to open any windows and risk letting in pollution – ideal if you live in a city. To find out the top health benefits of our air conditioning units, read our blog.

Q: “How big is the internal condenser unit?”

A: We have a wide range of condensers that increase in size depending on the number of indoor units they are required to provide cool air to. The smallest condenser we have is just 425mm x 535mm x 295mm.


Through-The-Wall Air Conditioning FAQs

Q: “What external modifications would be made to the property?”

A: Our through-the-wall air conditioning unit requires no external condenser unit, unlike a conventional air conditioning system. 

The only modifications to the exterior walls are very minor and in the form of installing two small ventilation grills. This is to vent the hot air out of the property and fresh air into the property. 

The grills can be re-coloured to match the exterior brickwork so they’re next to invisible. On the inside of the external wall is where the indoor unit is installed, which has all of the necessary technology contained within.

Q: “So I’m able to make modifications to the external wall, but I have no room/can’t get planning permission for conventional systems”

A: Our through-the-wall unit is ideal for those who can make modifications to the exterior of their property but have no room for an external condenser since the vents are very small.

Q: “How does it work? Where does the condenser go?”

A: This unit works as an all-in-one unit. This means that everything required to condition the air is housed within the unit attached to the inside of an exterior wall.

Q: “Does your system come with a warranty?”

A: We understand that when investing in air conditioning, a warranty provides peace of mind just in case any unlikely accidents or malfunctions occur. Our through-the-wall units come with a 3-year warranty, with a very hands-on team we will resolve the issue effectively and efficiently, at no further cost to you.

Q: Can through-the-wall AC systems improve the air quality in my home?” 

A: Yes, they can. The system takes fresh air from the outside, passes it through a built-in filtration system, and expels hot air from the inside of the property to the outside.

This process increases the overall quality of the air in your home and creates a healthier environment for those who suffer from asthma and other respiratory issues. To find out the top health benefits of our air conditioning units, read our blog.
