Compare air-conditioning and ventilation options for your business. We help you choose a practical system for the building, occupancy and way your spaces are used.
Comprehensive Commercial Solutions
Different buildings need different approaches to heating, cooling and fresh air. We assess the site before recommending equipment, with the design, controls, access and future maintenance considered together.
Split Systems
Practical for small to medium-sized commercial spaces, these systems include ceiling cassettes, wall units, and ducted options. They are a popular choice for functional and aesthetic reasons. Modern split systems offer dual cooling and heating functionality ensuring year-round comfort and good energy efficiency.
CONTACT USVRF/VRV Systems
Variable refrigerant flow (VRF) systems connect multiple indoor units to outdoor equipment and adjust refrigerant flow to suit demand. VRV is Daikin’s name for this type of technology.They can suit buildings with several zones. The available heating and cooling modes depend on the system design; suitable heat-recovery systems can heat and cool different areas at the same time. We assess layout, capacity, controls and service access before recommending a solution.
HVAC
HVAC means heating, ventilation and air conditioning. It describes the building services that work together to manage comfort and fresh air, rather than a single type of air-conditioning unit. We consider how those systems and their controls should work together for your site.
CONTACT USMVHR
Mechanical ventilation with heat recovery (MVHR) supplies fresh air and extracts stale air. A heat exchanger transfers heat between the air streams, helping reduce ventilation heat losses. It serves a different purpose from air conditioning; we assess whether ventilation, cooling or a combined approach suits the building.

CONTACT USFrequently asked questions
How much noise is it going to make?
This varies depending on the system manufacturer, as well as the installation type. We will be able to give you more information when discussing your specific installation.
How big should my office be to install a VRF?
Floor area is only one factor. We also assess heating and cooling demand, the number of zones, available outdoor space, pipe routes and maintenance access. A survey helps establish whether VRF or another system is appropriate.
Why should we upgrade our air conditioning system?
An upgrade may help where equipment is unreliable, difficult to maintain or no longer suits the building. We compare the condition and performance of the existing system with replacement options, including controls and likely running costs, before recommending a change.
