What is the optimal AC setting for comfort throughout the year?

To achieve a balance between comfort and efficient energy use, the US Energy Department recommends setting your air conditioner to 25 °C (78 °F) during the summer months and 20 °C (68 °F) in the winter.

Is air con worth it in the UK?

Air conditioning, or "air con," for homes in the UK is a topic that requires careful consideration. The need for air conditioning at home in the UK is influenced by several factors, such as climate, personal preferences, and budget. While the UK generally experiences milder summers compared to some other regions, there are still periods of hot and humid weather that can make indoor environments uncomfortable. Additionally, homes in the UK often lack built-in cooling systems, as they traditionally prioritise heating for colder seasons.


Investing in air conditioning for your home in the UK can provide numerous benefits. During warmer weather, it may help make a home more pleasant, which can improve sleep, productivity, and general wellbeing. By removing allergies and pollutants from the air, air conditioning may also enhance the quality of the air indoors. It is important to take into account the associated expenses, encompassing both the initial setup expenditures and continuous energy usage. Energy-efficient models and proper usage can help mitigate the impact on electricity bills.


Ultimately, the decision of whether air conditioning is worth it for your home in the UK depends on your specific circumstances, climate considerations, and personal comfort preferences. Assessing the frequency and severity of hot weather in your location, as well as your financial situation and less expensive alternatives like fans or evaporative coolers, may be helpful.

Which type of AC is best for home?

When it comes to choosing the best type of air con for homes in the UK, several factors should be considered.

Portable air conditioning units are a convenient option for homes in the UK, as they offer portability and easy installation without the need for permanent modifications. While they have limitations in terms of cooling capacity and energy consumption, they can be a great solution, especially for renters or those who need flexibility in cooling different rooms.

Split-system air conditioners are a popular choice as they offer energy efficiency, quiet operation, and better air distribution. With a sleek indoor unit, they blend well with interior designs and can effectively cool individual rooms or specific areas of the house.

Multi-split system air conditioners provide similar benefits but allow for multiple indoor units to be connected to a single outdoor unit, offering flexibility in cooling multiple rooms or zones.

For larger homes or those seeking whole-house cooling, ducted air conditioning systems are worth considering. These systems use a network of ducts to distribute cool air throughout the entire home, providing centralised control and discreet installation.

The best type of air conditioning for a home ultimately depends on individual requirements, budget, and the specific layout of the house.

Can an air conditioner cool an entire house?

An air conditioner's ability to cool a whole house depends on factors such as the size of the house, the cooling capacity of the unit, and the shape of the house. Central air conditioning systems, or ducted air conditioning systems, are designed to effectively cool an entire house by distributing cool air through a network of ducts, ensuring consistent and even cooling throughout. Proper sizing of the air conditioner is crucial to ensure efficient and effective cooling, as an undersized or oversized unit can lead to inadequate or inefficient performance.


However, for smaller homes or those with specific cooling requirements, alternative options like portable air conditioners, split-system air conditioners, or multi-split-system air conditioners can be used to cool individual rooms or zones effectively, although they may not provide comprehensive whole-house cooling.

How much does it cost to install aircon in one room UK?

The cost of installing air conditioning in one room in the UK can vary based on factors such as the chosen system type, room size, installation complexity, and desired features. On average, the installation cost can range from £1,500 to £4,000 or more. This includes the purchase and installation of the air conditioning unit, necessary ductwork or piping, electrical work, and labour fees. It's crucial to remember that these are estimates, and that actual expenses may vary based on particular needs.


For cooling a single room, portable air conditioning units can be a suitable option. Portable air conditioners offer convenience and flexibility, as they can be easily moved from one room to another. They typically consist of a self-contained unit that requires minimal installation and can be plugged into a standard electrical outlet. For best performance and comfort, take into account the energy efficiency rating, noise level, and cooling capacity of the portable air conditioner you choose. Additionally, proper venting is necessary to remove hot air and humidity from the room. All things considered, portable air conditioners offer a useful way to chill a single room without requiring intricate installation or long-term renovations to the area.

How much does it cost to have AC in UK?

The cost of having air conditioning in the UK can vary depending on factors such as the type of system, the size of the home, and individual preferences.

Cost to buy

In terms of the cost to buy, the price range for purchasing an air conditioning system for a typical UK home can start from around £1,000 and go up to several thousand pounds, depending on the system's capacity, features, and brand. Different types of systems, such as split-system air conditioners or ducted systems, may have varying price points.

Cost to run

When considering the cost of running air conditioning at home, it depends on factors such as the energy efficiency of the system, the duration and frequency of usage, and the electricity rates in the specific location. Energy-efficient models with high Seasonal Energy Efficiency Ratio (SEER) ratings can help reduce running costs by consuming less electricity. On average, running air conditioning in the UK can cost around £0.15 to £0.30 per hour, but this can vary based on the factors mentioned earlier.

The cost of operating an air conditioner can vary based on a number of factors, including the kind of unit, the size of the room it is cooling, and its energy efficiency. When it comes to home aircon in the UK, it's important to consider both the initial investment cost and the ongoing operational expenses. Conventional cooling systems, such as centralised or ducted air conditioners, tend to have higher installation costs, especially for larger homes. These systems require professional installation, including the setup of ductwork throughout the house. Since they require a large quantity of power to chill the entire house, their running expenses can also be high.

However, if you want air conditioning at home, portable air conditioners are a more affordable option. Given that they don't require considerable installation or ducting, they often have reduced upfront expenses. Portable units are designed to cool specific rooms or areas, allowing for targeted cooling and reduced energy consumption compared to centralised systems. While they still consume electricity, their running costs can be more manageable, especially if they are used in smaller spaces.
