Frequently asked questions
Managing HVAC and refrigeration across a commercial site comes with different considerations. Here are answers to common questions about Trimech's commercial services.
Can HVAC work be planned around business hours?
Commercial work can be planned around the requirements of the individual site. Trimech considers how the business operates when planning installation, servicing and maintenance, including the need to minimise unnecessary disruption.
Can one provider manage HVAC and refrigeration?
Yes. Trimech has in-house capabilities across commercial HVAC and refrigeration, allowing businesses with multiple system types to work with a single service provider rather than coordinating separate teams.
What HVAC systems suit multi-zone buildings?
Trimech works with VRV and VRF multi-zone systems for larger buildings, as well as ducted commercial systems for offices, retail and hospitality sites. The appropriate setup depends on the building and its heating and cooling requirements.
Do you service temperature-critical businesses?
Yes. Trimech supports businesses where temperature control is essential, including food-handling and processing sites, supermarkets, hospitality venues, aged care facilities, orchards, and wineries.
Can you maintain HVAC across multiple locations?
Trimech has teams across Young, Parkes, Moss Vale, and Goulburn, supporting commercial customers across multiple regional NSW service areas. Maintenance requirements can be planned around the sites and systems involved.
