Our Airconditioning Installation Expertise

Our specialists have over 25 years of experience in designing and installing air conditioning systems across London and the South East.

As a result, we can assist you in making informed and cost-effective decisions about replacement or brand-new equipment, from a single air conditioning unit to more extensive installations.

We are able to design applications to suit all requirements from single stand-alone or multi split air conditioner systems to complex VRV/VRF and close control systems.

Your requirements may involve an open-plan office or a business-critical server room. Perhaps you are undertaking an office refurbishment or you have a ‘live’ building. It may be that the necessary work needs to be undertaken out-of-hours.

Furthermore, we have cultivated great working relationships with all of the major air conditioning manufacturers allowing us to offer a complete range of installation options.
