When you move forward with repair

When the HVAC system in a commercial property goes down, the impact can reach employees, customers, tenants, equipment, and day-to-day operations. Other projects require planning well before the system ever turns on, especially when you’re building a new facility, updating an older property, or coordinating custom ductwork. Northern Air provides commercial services in Fort Collins, CO, for businesses, property managers, contractors, and building owners who need experienced HVAC support at different stages of a property’s life.

Commercial HVAC Services Northern Air Offers

Commercial HVAC work can involve an immediate equipment problem, ongoing system care, or coordination across an entire construction project. Northern Air works with existing commercial properties and new builds, providing HVAC support based on the equipment, building requirements, and scope of work involved.

Commercial Heating and Cooling

Commercial buildings depend on heating and cooling equipment that can keep occupied spaces comfortable through changing Fort Collins weather. Northern Air services commercial HVAC systems, diagnosing performance problems and helping businesses address equipment that is no longer heating or cooling as expected.

New Construction HVAC

HVAC decisions made during construction affect equipment placement, airflow, ductwork, controls, and access for future service. Our new construction HVAC services support commercial projects that need heating, cooling, ventilation, and duct systems planned alongside the rest of the build.

Custom Sheet Metal Fabrication

Some commercial HVAC projects require ductwork or metal components built for a particular space rather than standard off-the-shelf pieces. Northern Air provides sheet metal fabrication for custom HVAC applications, helping contractors and property owners get components made for the requirements of the project.

Commercial HVAC Retrofits

Older commercial buildings may need HVAC updates without undergoing complete reconstruction. Our HVAC retrofitting capabilities allow us to evaluate existing systems and plan equipment or system changes around the building that is already in place.

Emergency Commercial HVAC Repair

A heating or cooling failure can quickly interfere with normal business operations, particularly during periods of extreme temperatures. Northern Air provides 24/7 emergency HVAC services for urgent commercial equipment problems, backed by a 24/7 answering service for requests outside regular business hours.

Commercial HVAC Maintenance

Routine service gives businesses an opportunity to address wear and operating concerns before equipment problems become more disruptive. Northern Air can inspect commercial HVAC equipment, evaluate system operation, and identify conditions that may require attention. Businesses interested in recurring service can also ask about our Planned Maintenance Program.

Types of Commercial Buildings We Service

Commercial properties place different demands on their HVAC systems depending on occupancy, building layout, operating hours, and how the space is used. Northern Air works with commercial properties throughout Fort Collins, adapting service and project planning to the building and its HVAC requirements.

  • Office Buildings: Heating and cooling for individual offices, shared workspaces, conference areas, and multi-zone commercial systems.

  • Retail Properties: HVAC service for stores and customer-facing spaces where indoor temperatures can affect daily operations.

  • Restaurants and Food Service Properties: Heating, cooling, and HVAC support for properties with changing occupancy and additional heat generated by food-service operations.

  • Warehouses and Industrial Spaces: HVAC solutions for larger spaces where equipment layout, airflow, and building use affect heating and cooling requirements.

  • Multi-Tenant Commercial Properties: Service for buildings where separate areas or tenants may depend on different zones, controls, or HVAC equipment.

  • New Commercial Buildings: HVAC installation, ductwork, and system planning for properties under construction.

  • Renovated and Retrofitted Properties: HVAC updates for existing commercial buildings undergoing equipment replacements, layout changes, or broader renovations.

Why Fort Collins Businesses Work With Northern Air

Commercial HVAC work often involves more than getting a piece of equipment running again. Building access, operating schedules, system configuration, project timelines, and coordination with other trades can all affect how the work needs to be handled. Northern Air brings more than 230 years of combined HVAC experience to commercial projects, with technicians averaging 14 years with the company. Our capabilities include service and repair, new construction HVAC, retrofits, and custom sheet metal fabrication, allowing our team to support both existing properties and larger commercial projects. When an unexpected HVAC failure threatens business operations, our 24/7 answering service also provides a way to request assistance outside normal business hours.

Keep Your Commercial HVAC Project Moving

An HVAC problem can interrupt the work happening inside your building, while a poorly planned installation can create problems long after construction is finished. Northern Air works with business owners, property managers, and contractors to address immediate equipment needs and plan commercial HVAC projects around the property itself.

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.
