We were contacted by Meridian after providing general servicing to some wall units and computer room systems. Over time and the success of Meridian the occupancy numbers have increased and the company now occupies three floors at Robberts House in Altrincham. We were invited to quote to provide a solution to unbearably hot conditions in the buildings and liaise with the landlord for permission to install equipment on the roof of the five storey building.

The proposal was to install cassette units in all open plan zones and wall units into small offices. Each floor would be serviced via its own outdoor VRF condenser. The equipment selected was Mitsubishi Heavy Industry and provided a two pipe system to suit Meridians requirements of seasonal cooling and to top up heating in the winter.

Installation Requirements

All of the work had to be done out of hours and the majority of indoor work was completed between 6pm and 3am Monday to Friday. Some weekend work was also required initially to remove all of the old wall units on the 4th floor, including all pipe work and cables as well as the old R22 outdoor units from the roof. We are experienced in working in busy offices and made sure everything was back in place and tidy for the Merdian staff the following day.

The ceiling voids were too shallow to accomodate any other type of system and each cassette had a bespoke infill surround to finish the installation.


Every unit has individual control via LCD touch screen displays to help achieve the perfect ambiance in the room.

Roof Work

The roof equipment was lifted into place using Sutton Crane Hire, early on a Saturday morning, as the lift required a road closure we had to work quickly resulting in the three units being in place within two hours. We commissioned the systems and ran, each floor was at temperature within two hours from 31°c / 70% RH to 22°c / 55% RH.

The overall consensus was very positive and staff were extremely happy to stay in the office when temperatures outside reached 30°c.

Once the work was completed we provided Meridian with a scheduled service plan and visit every 3 months to insure all the units are in the best condition.
