Installation of Electriq Multi-Split AC Units for Terrace House in Brixton
I’m looking to have two air conditioning units installed inside my terrace house in Brixton, with one fan (outdoor condenser) on the outside wall. It’s on an extension, so the units will be on the same wall on either side. I’m planning to buy an Electriq multi-split system (18,000 BTU). Please call to arrange an appointment.
Expert Advice on Installing Multi-Split Air Conditioning Units
Installing an Electriq multi-split air conditioning system in a terrace house is an excellent way to achieve efficient climate control in multiple rooms. For Joe’s property in Brixton, the configuration of two indoor units connected to a single outdoor condenser on the same wall simplifies installation while maximising system efficiency. Below, we outline the key steps and considerations for this project.
Why Choose an Electriq Multi-Split System?
The Electriq multi-split system with a cooling capacity of 18,000 BTU is well-suited for terrace houses, providing targeted cooling for two rooms while minimising outdoor unit space. Key benefits include:
- Compact Design: A single outdoor unit reduces external clutter, ideal for terrace houses with limited outdoor space.
- Energy Efficiency: Multi-split systems operate more efficiently than individual units for each room.
- Customised Comfort: Each indoor unit can be controlled independently, allowing for tailored temperature settings.
Installation Process
The installation of a multi-split system involves the following steps:
- Site Assessment: A detailed survey will determine the best locations for the indoor units and the outdoor condenser. For this project, the shared wall of the extension simplifies pipe routing and installation.
- Indoor Unit Mounting: The two wall-mounted units will be installed in their respective rooms, ensuring optimal airflow and aesthetics.
- Outdoor Unit Installation: The outdoor condenser will be securely mounted on the exterior wall, positioned for easy access and noise minimisation.
- Connecting Components: Refrigerant pipes, electrical cables, and drain lines will be routed through the shared wall, keeping connections neat and concealed.
- System Testing: Once installation is complete, the system will be tested for refrigerant leaks and operational efficiency. Each indoor unit will be calibrated for independent operation.
Estimated Costs
The cost of installing an Electriq multi-split system includes both the unit and installation services. Estimated costs are as follows:
- Electriq Multi-Split System (18,000 BTU): £1,200–£1,800 (depending on supplier).
- Installation Labour: £700–£1,200 for two indoor units and one outdoor unit, including pipe routing through the shared wall.
- Additional Materials: £150–£300 for brackets, insulation, and trunking.
Challenges and Solutions
While this installation is straightforward, routing pipes and cables through the shared wall must be done carefully to avoid structural damage. Professional installers use tools and techniques to minimise disruption and ensure a clean finish. Noise levels from the outdoor unit are also considered, especially in terrace houses where outdoor space is shared closely with neighbours.
Benefits of Professional Installation
Choosing professional installation ensures:
- Safe and Compliant Setup: Adherence to industry standards for refrigerant handling and electrical work.
- Optimised Performance: Proper placement and calibration of units for maximum efficiency.
- Neat Finish: Concealed or tidied pipework for a seamless appearance.
Preparing for Installation
To prepare for the installation, clear the areas where the indoor units will be mounted and ensure access to the shared wall. If the outdoor unit’s location requires adjustments to garden furniture or other fixtures, ensure the space is ready for installation day.
