Domestic Air Conditioning Installation
We specialise in installing energy-efficient air conditioning systems for residential properties. Our F-Gas certified engineers fit wall-mounted and low-wall units in bedrooms, kitchens, conservatories, and offices. Using leading brands like Mitsubishi and Daikin, we ensure quiet operation and even airflow. Every installation includes a 48-hour quotation, site survey, and optional maintenance packages for long-term performance.
Split Air Conditioner Systems
Split systems connect indoor and outdoor units via copper pipes, eliminating the need for ductwork. Ideal for homes without existing HVAC infrastructure, these systems provide zoned temperature control. Single-split systems suit individual rooms, while multi-split variants manage multiple spaces with one outdoor compressor. We offer ENERGY STAR-rated models to reduce energy bills and environmental impact.
Commercial HVAC Solutions
We install scalable air conditioning systems for offices, restaurants, schools, and car dealerships. Our engineers handle large-scale multi-split systems with up to five indoor units per compressor. Services include site surveys, bespoke maintenance contracts, and compliance with commercial refrigeration standards. Clients benefit from minimal disruption during installation and long-term efficiency guarantees.
Maintenance Packages
Regular maintenance extends system lifespan and efficiency. Our packages include seasonal inspections, filter cleaning, refrigerant checks, and performance optimisation. Tailored to domestic and commercial needs, these plans prevent breakdowns and maintain manufacturer warranties. Customers receive priority emergency call-outs and discounted repair rates as part of their subscription.
Emergency Repairs
We provide round-the-clock emergency repairs for critical system failures. Our rapid-response team addresses issues like refrigerant leaks, compressor faults, and electrical malfunctions. Using diagnostic tools and spare parts inventory, we resolve problems swiftly. This service is available to all customers, with priority given to maintenance package holders.

Excellent service. Done in a day for three units and cleaned up after themselves as they went so there was no mess. Worked well with our electrician.

Paul Warder and his team have been installing air conditioning & ventilation for Stephen James BMW for nearly 20 years, they have installed and maintained more than 100 split & VRF systems across all of our sites. They have just completed a new Mitsubishi cooling system at our showroom in Enfield. I would recommend A10 Air Conditioning without any hesitation for your business.

Paul and his team at A10 have done a grand job in installing the AC units. A10 have been competitive in their pricing and have been patient in providing all the necessary information. The work was timely, clean, and efficient. After the installation we had a small issue with a pump and Paul was quick to come back and sort it out. I would not hesitate in recommending A10.
