When you move forward with repair

Commercial HVAC projects tend to have a lot of moving pieces. Equipment needs to fit the building, ductwork has to work around structural plans, installation needs to stay coordinated with other trades, and decisions made early can affect how the finished system operates for years. Northern Air handles commercial projects in Fort Collins, CO, bringing HVAC planning, installation, and custom fabrication capabilities together for new and existing properties.

Our commercial project team works with contractors, property owners, developers, and facility managers on jobs that require more than a standard service visit. From new construction and building renovations to equipment upgrades and custom ductwork, we approach each project around its mechanical requirements, construction schedule, and intended use.

What We Consider Before Commercial HVAC Work Begins

Planning ahead helps prevent HVAC conflicts once construction is underway. Northern Air reviews the mechanical scope, building layout, and project requirements before installation begins.

  • Building use and occupancy: How the finished space will be used affects heating, cooling, ventilation, and controls.

  • Equipment placement: We account for installation space, connections, and future service access.

  • Duct routing: Ductwork is planned around structural elements and other building systems.

  • Existing infrastructure: Retrofit projects require evaluating what can remain and what needs modification.

  • Controls and zoning: Different areas may require separate temperature controls based on layout and use.

  • Project sequencing: We coordinate HVAC work with construction stages and other trades.

Commercial HVAC Projects We Handle

Every commercial project comes with its own mechanical requirements, building constraints, and schedule. Northern Air works on planned HVAC projects where equipment selection, ductwork, fabrication, installation, and coordination need to be considered together. Our team can become involved during early planning or help address HVAC needs within an existing project scope.

New Commercial Construction

New construction gives the HVAC team an opportunity to plan equipment locations, duct routing, ventilation, controls, and access before the building is finished. Our new construction HVAC services support commercial builds where mechanical work needs to stay coordinated with structural, electrical, and other construction activities.

Commercial Renovations and Build-Outs

Changing the layout or use of an existing commercial space can also change its heating and cooling requirements. We can evaluate how walls, occupancy, equipment, and new room configurations affect the existing HVAC setup, then determine what modifications are needed for the renovated space.

HVAC Retrofits and Equipment Upgrades

Older commercial properties do not always require an entirely new mechanical system. Northern Air provides HVAC retrofitting for projects involving equipment upgrades, system modifications, control changes, and other improvements that need to work within an existing building.

Custom Ductwork and Sheet Metal

Commercial buildings frequently require duct sections, transitions, fittings, plenums, and other components made for specific dimensions or equipment configurations. Our sheet metal fabrication capabilities allow us to produce custom HVAC components for new installations, renovations, and system modifications.

Commercial HVAC Equipment Installation

Equipment installation needs to account for more than the unit itself. Northern Air considers connections, airflow, controls, ductwork, equipment access, and how the system fits into the larger mechanical plan. Our commercial HVAC experience supports heating and cooling installations across different types of business properties.

JJ and Scott were professional, personable and efficient. The system works great and the house was cleaner when they left than when they arrived. I can't say enough about Northern Air.
