Air Conditioning Installation
We design and install air conditioning systems for commercial and residential properties, ensuring energy efficiency and optimal comfort. Our solutions include wall-mounted, ducted, and cassette units tailored to spaces like offices, retail outlets, and homes. With partnerships with leading manufacturers, we offer warranties up to 7 years and 24/7 emergency support.
Commercial Ventilation
Our ventilation systems enhance indoor air quality by removing stale air and introducing filtered fresh air. Heat recovery units reduce energy costs by transferring heat between exhaust and supply air. Ideal for offices, factories, and schools, these systems prevent condensation, improve staff productivity, and comply with health and safety regulations.
Data Centre Cooling
Critical environments like data centres require 24/7 temperature control. We supply and maintain reliable cooling systems with standby units and remote monitoring. Our solutions ensure 100% uptime for server rooms, protecting sensitive equipment from overheating and minimising downtime risks for businesses.
Heat Pump Systems
We install air-to-air and air-to-water heat pumps for residential and commercial properties, offering an eco-friendly alternative to gas or oil heating. These systems provide efficient year-round comfort, reducing energy bills while maintaining consistent temperatures in homes, offices, and industrial spaces.
HVAC Maintenance
Regular maintenance ensures HVAC systems operate efficiently and comply with F-gas regulations. Our services include filter cleaning, coil inspection, and performance checks. With planned preventative maintenance and emergency repairs, we extend system lifespan and prevent unexpected breakdowns for clients across Hampshire.
