Common questions
More answers on our FAQ page.
Do you build and service cool rooms?
Yes. We design, install and maintain walk-in cool rooms and freezer rooms, plus display and storage refrigeration for food, retail and hospitality.
What is heat recovery ventilation?
A heat recovery ventilation system brings in fresh air and passes it through a heat exchanger with the stale air going out, so you get fresh air without losing most of the heat or cooling you've paid for.
Can you help with commercial kitchen exhaust?
Yes. We install and service kitchen exhaust and make-up air systems, as well as general exhaust and fresh-air systems for offices, warehouses and car parks.
