Heating Services for Your Home or Business
Every heating system has different service requirements based on its design, age, fuel or energy source, and condition. Northern Air works with residential and commercial heating equipment in Fort Collins, diagnosing existing systems and helping customers plan for maintenance or replacement when needed.
Our technicians evaluate the equipment before recommending work. That means looking beyond the immediate symptom to determine whether controls, airflow, electrical components, mechanical parts, or other conditions are affecting system operation.
Heating Repair
When your heater stops working correctly, Northern Air’s heating repair technicians diagnose the cause before recommending a solution. We address heating failures, unusual operation, insufficient heat, cycling problems, and other equipment concerns.
Northern Air also has a 24/7 answering service for urgent residential and commercial HVAC problems. If a heating failure occurs outside normal business hours, customers have a way to reach our team and request assistance.
Heating Installation
A new heating system needs to fit the property rather than simply replace the old equipment with a similar unit. Our heating installation process considers the building’s heating requirements, existing HVAC configuration, equipment options, and comfort needs.
As a Lennox Premier Dealer, Northern Air can provide Lennox heating equipment while working with systems from other major manufacturers. We can also discuss efficiency, controls, and equipment features so you understand the differences between available options.
Heating Maintenance
Routine heating service gives a technician an opportunity to inspect the system before or during periods of frequent use. Depending on the equipment, service may involve inspecting electrical connections, controls, airflow, heating components, filters, and other parts that affect operation.
Customers who prefer recurring HVAC care can also use Northern Air’s Planned Maintenance Program to stay on top of scheduled system maintenance.
