Cooling Systems
We design and maintain air-cooled, water-cooled, and evaporative condenser chillers for industrial and commercial applications. Our systems prioritise energy efficiency, low noise, and minimal environmental impact while ensuring optimal temperature control. Specialising in Turbocor technology and natural refrigerants, we offer retrofit options and emergency hire solutions for critical operations.
Heat Pumps
Our air, water, and ground-source heat pumps provide sustainable heating solutions for commercial buildings. These systems reduce energy bills by up to 50% while qualifying for government incentives. We offer full installation, maintenance, and retrofit services tailored to manufacturing, new build, and retrofit projects.
Air Conditioning
From single units to complex VRF systems, we deliver energy-efficient air conditioning for commercial spaces. Our engineers specialise in VRV/VRF technology, MicroGuard anti-corrosion treatments, and portable hire solutions. Maintenance contracts ensure long-term performance and compliance with health and safety standards.
Parts & Spares
We supply genuine spares for major HVAC brands including Carrier, Trane, and York. Our extensive network ensures rapid availability of critical components, supported by technical advice for installation and troubleshooting. This service extends equipment lifespan and maintains system efficiency.
HVAC/R Monitoring
Our IoT-enabled systems continuously monitor energy use and equipment performance. Using Climacheck analysis and remote diagnostics, we identify inefficiencies and prevent breakdowns. This technology optimises energy consumption, reduces costs by 10-30%, and integrates with building management systems for real-time control.

Our company had multiple dealings with JSA service over the last month and I have to say that their efficiency went well beyond what was expected. A very well mannered and punctual outfit, we will certainly be doing business with them again!
