Air Conditioning Installation London – FAQ
1. Why is my new extension so hot in summer?
This is a common issue in modern extensions and refurbished homes. Large sliding doors, rooflights, improved insulation, and airtight construction help keep homes warm and energy efficient, but they can also cause rooms to overheat during warmer months.
Many rear extensions feature large areas of glazing that allow significant solar gain throughout the day. While this creates bright and attractive living spaces, it can also lead to uncomfortable indoor temperatures, particularly in south-facing or west-facing rooms.
Unlike older properties, modern extensions are designed to retain heat much more effectively. As a result, once a space heats up, it can be difficult to cool down naturally through windows and ventilation alone.
Air conditioning provides a reliable solution by helping maintain comfortable indoor temperatures, improving air circulation, and creating a more comfortable environment during hot weather. It is becoming an increasingly popular addition to extensions, open-plan kitchens, home offices, and refurbished properties across London.

At Kluk Construction, we often discuss cooling requirements during the design and planning stage of renovation and extension projects to help homeowners create comfortable living spaces that perform well throughout the year.
2. What type of air conditioning system is best for a home?
The best air conditioning system depends on your property’s layout, room size, interior design preferences, and cooling requirements. Wall-mounted split systems are one of the most popular choices for homes due to their energy efficiency, quiet operation, reliability, and modern appearance.
Many homeowners prefer concealed air conditioning units as they can be hidden within ceilings, bulkheads, or joinery, leaving only discreet grilles visible. However, concealed systems are not suitable for every property. In some older houses, limited ceiling voids, structural features, or the existing construction may make installation more challenging. Additional works such as ceiling lowering, bulkheads, or bespoke boxing may be required to accommodate ductwork and equipment.
Where a concealed solution is not practical or cost-effective, wall-mounted units often provide an excellent alternative. Modern wall-mounted systems are sleek, unobtrusive, and can usually be installed with less disruption while still delivering effective and energy-efficient cooling.
At Kluk Construction, we assess each property individually and recommend the most suitable solution based on the building structure, available space, aesthetics, and budget.
3. Can air conditioning be installed in an existing property?
Yes. Air conditioning can be installed in most existing homes, offices, and retail spaces, including older properties, apartments, and buildings undergoing refurbishment. Modern air conditioning systems are highly adaptable and can often be integrated with minimal disruption to the property.
Every installation is different, which is why our team carries out a detailed assessment before recommending a solution. We consider factors such as room size, property layout, access routes for pipework and cabling, the location of the external unit, and any planning or noise considerations that may apply.
Whether you require cooling for a single room, multiple rooms, a home office, a retail unit, or a workplace, we will recommend the most suitable system and installation approach to ensure efficient performance, reliability, and a clean, professional finish.
4. How long does air conditioning installation take?
Most residential air conditioning installations can be completed within couple of days, while larger or multi-room systems may take longer depending on the scope of the project.
5. Is air conditioning energy efficient?
Modern air conditioning systems are designed to be highly energy efficient. Choosing the correct system size and ensuring professional installation can help minimise energy consumption and operating costs.
6. Can air conditioning be installed in multiple rooms?
Yes. Multi-room air conditioning systems allow several rooms to be connected to a single outdoor unit, providing efficient cooling throughout the property.
7. Do I need planning permission for air conditioning installation?
In many cases, planning permission is not required for residential air conditioning installations. However, requirements can vary depending on the type of property, the location of the external unit, and local planning restrictions. Additional approvals may be required for listed buildings, conservation areas, flats, or certain commercial premises.
One of the most important considerations is the position of the external condenser unit. If the unit is installed close to a neighbouring property, boundary wall, or bedroom window, noise levels may become a concern. Although modern air conditioning systems are designed to operate quietly, local authorities may assess the potential impact on neighbouring properties, particularly in densely built areas of London.
Careful system design and unit placement can help minimise noise and reduce the likelihood of planning or neighbour-related issues. In some situations, quieter equipment, anti-vibration mounts, acoustic screening, or an alternative unit location may be recommended.
At Kluk Construction, we assess every installation individually, taking into account property layout, neighbouring buildings, access, appearance, and noise considerations to help ensure the system is installed in the most suitable location.
