Air Conditioning Installation: Wall Mounted Units on Second Floor in Paignton
We are looking to install air conditioning units in our semi-detached home on Queen Elizabeth Drive, Paignton (TQ3). We need two wall-mounted units: one for a bedroom and one for an office, both on the second floor. The outdoor unit will be mounted below 3 metres, and interior units will be placed on exterior walls. Piping needs to run through the attic, with lengths of 6.5m and 9.5m for the bedroom and office respectively. Additionally, 4m of trunking will be needed to connect the units to the soffit. The property is owner-occupied, and we are looking for a full supply and fit service.
Understanding the Requirements for Air Conditioning Installation
Installing air conditioning units in a semi-detached property like yours involves several considerations to ensure the system operates efficiently and seamlessly integrates with your home’s layout. Below, we’ll break down the key elements of your project and how these will be addressed.
Key Installation Considerations
Wall-Mounted Units and Placement
Wall-mounted units are an excellent choice for residential properties, as they are discreet and efficient. By placing the units on exterior walls, heat exchange is optimised, and installation becomes straightforward. The outdoor unit’s placement below 3 metres complies with standard safety and accessibility guidelines, making maintenance easier.
Piping and Trunking
The piping lengths of 6.5m and 9.5m will be routed through the attic, which ensures minimal intrusion into your living spaces. For trunking, 4m will suffice to create a neat and protected pathway for pipes leading to the soffit. Trunking not only enhances the aesthetic by concealing pipes but also protects them from environmental factors.
Room Dimensions and Cooling Needs
Based on your provided measurements, the bedroom (2.9m x 4.2m x 2.3m) and office (2.4m x 3.0m x 2.3m) are adequately sized for typical residential air conditioning units. Energy-efficient models can comfortably cool these spaces while maintaining a low noise level.
Installation Process
The installation process typically involves the following steps:
- Mounting the indoor units on the designated walls.
- Positioning and securing the outdoor unit below 3 metres for easy access.
- Routing pipes through the attic to minimise visible components indoors.
- Installing trunking from the units to the soffit to maintain a clean look.
- Connecting the units, charging the refrigerant, and testing the system for efficiency.
Materials and Costs
Materials needed for this project include the wall-mounted air conditioning units, piping (sized to fit your attic layout), and 4m of trunking. High-quality brands like Mitsubishi, Daikin, or LG are recommended for their reliability and energy efficiency. Costs will vary depending on the unit model and additional customisation requirements but generally range between £2,000 and £4,000 for a supply-and-fit service of this scale.
Preparation and Impact
Before installation, ensure attic access is cleared and the outdoor area for the unit is free of obstructions. The process should take 1–2 days, with minimal disruption to daily life. Installers will take care to protect your home during the process, ensuring a clean and professional finish.
Long-Term Benefits
Installing air conditioning not only improves comfort during hot weather but also adds value to your property. Modern units with heating capabilities can provide year-round climate control, reducing overall energy bills in the long run.
