Expert Furnace Repair Services in Fort Collins

When your furnace breaks down during a Colorado winter, you need reliable heating repair fast. At Northern Air, we understand the urgency of restoring warmth to your home. Since our founding in 1992, we’ve responded to thousands of emergency furnace repair calls throughout Fort Collins and the entire Front Range. Our locally owned and family-operated HVAC company brings more than 40 years of experience directly to your doorstep, available 24/7 for those unexpected heating emergencies that never seem to happen at convenient times.

Our team of certified heating and A/C technicians approaches every furnace repair with a commitment to understanding your individual indoor comfort needs. We take every step necessary to diagnose the root cause of your heating system’s problems, not just treat the symptoms. This comprehensive approach ensures that when we complete a repair, your furnace operates efficiently and reliably for the long term.

Common Furnace Problems We Diagnose and Repair

Furnaces are complex systems with multiple components that must work together seamlessly to provide consistent heat throughout your home. We frequently encounter issues ranging from simple thermostat malfunctions to more complex heat exchanger failures. Ignition problems represent approximately 30% of furnace repair calls during peak heating season. These issues often manifest as intermittent heating, where your furnace cycles on and off without maintaining consistent temperatures. Our technicians carry advanced diagnostic equipment to quickly identify whether the problem stems from a faulty ignitor, flame sensor, or control board malfunction.

Airflow restrictions account for another significant portion of heating repair needs in Fort Collins homes. When your furnace struggles to distribute warm air effectively, the cause might be a clogged filter, blocked vents, or a failing blower motor. We examine the entire air distribution system, measuring static pressure and airflow rates to pinpoint exactly where the restriction occurs. This thorough diagnostic process prevents unnecessary component replacements and ensures we address the actual problem affecting your comfort.

The Northern Air Furnace Repair Process

When you call us for furnace repair, we begin with a comprehensive system evaluation that goes beyond simply identifying the immediate problem. Our technicians inspect all major components including the heat exchanger, burners, safety controls, and ventilation systems. We check gas pressure levels, measure temperature rise across the heat exchanger, and test all safety devices to ensure your furnace operates within manufacturer specifications. This detailed inspection often reveals developing issues that, if left unaddressed, could lead to more expensive repairs or complete system failure down the road.

As a Lennox Premier Dealer, we maintain extensive inventory of genuine replacement parts for all major furnace brands. This designation means we’ve met rigorous standards for technical expertise, customer satisfaction, and business excellence. Our service vehicles carry the most commonly needed parts, allowing us to complete many repairs during the initial service call. For specialized components, our strong relationships with suppliers ensure rapid procurement, minimizing your downtime without heat.

Preventive Heater Maintenance and Long-Term Solutions

While emergency furnace repair is sometimes unavoidable, regular maintenance dramatically reduces the likelihood of unexpected breakdowns. Industry data shows that properly maintained heating systems experience 75% fewer emergency repairs and operate at 95% of their rated efficiency compared to neglected units. We recommend annual furnace tune-ups that include:

  • Thorough cleaning of burners and heat exchanger surfaces to maximize heat transfer efficiency
  • Calibration of gas pressure and combustion settings for optimal fuel consumption
  • Inspection and testing of all safety controls including limit switches and flame rollout sensors
  • Lubrication of moving parts to reduce wear and extend component life
  • Complete electrical system check including amp draws and voltage measurements

These preventive measures extend your furnace’s operational life while maintaining peak efficiency throughout the heating season. Our maintenance programs include priority scheduling for any needed repairs and often help identify minor issues before they escalate into major problems requiring emergency service.

Been working with Bill D for a couple years at a our home and my mother's home. Recently had the pleasure of working Matt at our business. I can't tell you what a relief it is to have such a trustworthy team to work with. These two gentlemen are absolutely top notch. Highly recommend!

The technician that came out, Ronnie, was absolutely wonderful. Extremely professional, quickly installed the new thermostat, and even showed me step by step how to set up the scheduling option on the new one.

Every time Northern Air sends someone out, the work is always done quickly and their prices are definitely more reasonable than most of the companies in the area!

Bill, God bless him, came out on a 100 degree Sunday and fixed our A/C. He had great communication, was on time, and knew exactly what to do and saved the day! I appreciated his great attitude and kind spirit as well. The price was reasonable for a weekend visit. We will definitely use them again!

Northern Air installed Central Air in my home in Fall 2021 (I did not have it). I also wanted a high efficiency furnace since my furnace was over 23 years old, even though it was still working. I got bids from 5-6 other HVAC companies. None of them were interested in installing a high efficiency furnace, even the companies recommended by “Efficiency Works” One company would not even install Central Air because they could not figure out how to install in my crawl space. Northern Air were great, efficient, neat, and had the best prices as well!
