Commercial Heating and Cooling in Winnipeg

Winnipeg puts mechanical systems through everything, from deep winter cold to demanding summer heat. In a climate this extreme, heating and cooling aren't comfort features, they're critical infrastructure. Randall installs, services, and maintains the full range of commercial heating and cooling systems, rooftop units and heat pumps included, with the experience to keep buildings of every size running through every season.

Commercial Boiler Service and Replacement

Boiler work is a Randall specialty, with a service team trained and licensed for the largest systems in the city:
  • Replacement and installation: When repair stops making sense, we'll guide the replacement honestly and handle the installation completely
  • Repairs and service: Our technicians receive continuous, manufacturer-led training across a wide range of boiler systems
  • Class A Gasfitter licensed: Our team holds Class A Gasfitter licenses, qualifying us to work on the larger boilers in larger buildings
  • Fire inspections: Required by the City of Winnipeg, and we're certified to perform them

Commercial Refrigeration and Air Conditioning

Our refrigeration team focuses on the systems commercial buildings depend on:

  • Commercial building air conditioning: Installation, service, and replacement
  • Heat pumps: Efficient heating and cooling through a single system
  • Critical cooling: Specialized, redundant cooling for data rooms, LAN rooms, and other spaces where 24/7 operation isn't negotiable

Making It Last: Annual Maintenance Contracts

The most cost-effective service call is the one you never need. Randall offers annual maintenance contracts for commercial buildings, covering scheduled visits throughout the year, from filter changes and equipment inspections to annual fire inspections and heating start-up.

Whether you manage a portfolio or a single building, a contract means your systems are looked after. And when something does come up, you already have a team that knows your building.
