Installing Two Wall-Mounted Air Conditioning Units in a Semi-Detached House in London

I’m looking to install two air conditioning units that I’ll be buying—one in the living room and one in the bedroom. Both rooms are roughly 6m by 4m, and the venting needs to go through another room to reach the back of the house. I’m not sure what types and models would be suitable.

Choosing Suitable Air Conditioning Units

For rooms of approximately 6m x 4m (24m²), units with a cooling capacity of around 2.5kW to 3.5kW are typically sufficient. When purchasing your units, ensure they are split systems with wall-mounted indoor units and a single outdoor condenser to save space and simplify installation.

Some reliable models to consider include:

• Daikin Comfora 2.5kW–3.5kW: Known for quiet operation and energy efficiency.
• Mitsubishi Electric MSZ-AP35VG: Compact design with smart control options.
• Panasonic Etherea 3.5kW: Features advanced air purification and efficient cooling.

Installation Process for Wall-Mounted AC Units

Here’s how the installation process will typically proceed:

1. Site Assessment

A professional installer will assess the property to determine the best placement for the indoor and outdoor units. They’ll also plan the route for the refrigerant pipes and electrical wiring, considering the need to pass through an additional room to reach the back of the house.

2. Wall Mounting Indoor Units

• The living room and bedroom units will be securely mounted on interior walls, positioned for optimal airflow and minimal disruption to the room’s layout.

3. Routing and Venting

• Refrigerant pipes and venting ducts will be routed through the intermediate room to connect to the outdoor condenser. This involves carefully concealing pipes and protecting them with trunking for a clean finish.

4. Outdoor Unit Installation

• The outdoor condenser will be installed at the back of the house, positioned for adequate ventilation and accessibility for maintenance.

5. Testing and Commissioning

• Once installed, the system will be tested for proper operation, including cooling performance, airflow, and thermostat functionality.

Costs and Timeline

The cost of installing two wall-mounted air conditioning units in London typically ranges from £1,000 to £2,000 for installation only. Factors influencing cost include:

• Complexity of venting and pipe routing.
• Accessibility of indoor and outdoor unit locations.
• Length of refrigerant pipes and additional materials required.

The installation process usually takes 1–2 days, depending on the complexity of routing and mounting.

Considerations for Venting Through Another Room

• Ensure the routing path does not interfere with furniture or obstruct walkways.
• Discuss with the installer how to minimise visual impact using trunking or concealing pipes within walls, if possible.
• Confirm that the additional room has proper ventilation to avoid heat build-up from the pipework.

Benefits of Professional Installation

Engaging a certified installer ensures:

• Compliance with safety standards and manufacturer warranties.
• Precise placement for maximum efficiency and comfort.
• Seamless integration of the system with minimal disruption to your home.
