Your Trusted HVAC Partner in Fort Collins Since 1992

Fort Collins residents understand the importance of reliable heating and cooling systems throughout our dynamic Colorado seasons. At Northern Air, we’ve been serving this vibrant community since our founding in 1992, bringing over 40 years of combined HVAC expertise to every home and business we service. As a locally owned and family-operated company, we understand the unique climate challenges that Fort Collins properties face, from scorching summer afternoons to frigid winter mornings that can drop well below freezing.

Our commitment to Fort Collins extends beyond simple repairs and installations. We’ve built our reputation on understanding each customer’s individual indoor comfort needs, whether you’re dealing with the dry mountain air that affects humidity levels or the sudden temperature swings that characterize our region. Our team of certified technicians specializes in comprehensive solutions that address the specific environmental factors affecting Fort Collins homes, including elevation-related pressure differences and the intense UV exposure that can impact HVAC system components.

Comprehensive Air Conditioning Services for Colorado Summers

When summer temperatures in Fort Collins climb into the 90s, your air conditioning system becomes essential for maintaining comfort and productivity. Our air conditioner service offerings encompass everything from routine maintenance to complete system replacements, ensuring your home stays cool during those intense July and August heat waves. We perform thorough multi-point inspections that examine refrigerant levels, electrical connections, condenser coils, evaporator components, and thermostat calibration to maximize efficiency and prevent unexpected breakdowns.

AC installation requires careful consideration of numerous factors specific to Fort Collins properties. We evaluate square footage, insulation quality, window placement, sun exposure, and existing ductwork to recommend appropriately sized systems that deliver optimal cooling without excessive energy consumption. Our expertise with modern high-efficiency units helps homeowners reduce utility costs while maintaining superior comfort levels. As a Lennox Premier Dealer, we offer access to industry-leading equipment with SEER ratings that exceed federal efficiency standards, providing long-term savings and environmental benefits.

Expert Heating Solutions for Northern Air Winters

Fort Collins winters demand heating systems that perform reliably when temperatures plummet and snow accumulates. Our heating service expertise covers all system types, including forced air furnaces, heat pumps, boilers, and hybrid systems that combine multiple technologies for maximum efficiency. We understand how altitude affects combustion efficiency and adjust our installation and service procedures accordingly, ensuring your heating equipment operates at peak performance despite our 5,000-foot elevation.

Regular heating maintenance proves particularly crucial in our climate, where systems often run continuously during cold snaps. Our technicians inspect heat exchangers for cracks, test safety controls, clean burners, check gas pressures, and verify proper ventilation to prevent carbon monoxide risks. We also examine ductwork for leaks that waste heated air and increase energy costs, sealing gaps and improving insulation where necessary.

Emergency HVAC Support When You Need It Most

Equipment failures rarely occur at convenient times, which is why we maintain 24/7 availability for emergency AC repair and heating system breakdowns. Our rapid response team understands that comfort emergencies require immediate attention, especially during extreme weather events that frequently impact Fort Collins and surrounding communities including Loveland, Timnath, Wellington, Windsor, and Laporte.

Energy Efficiency and Indoor Air Quality Solutions

Modern HVAC technology offers remarkable opportunities for improving energy efficiency and indoor air quality simultaneously. We help Fort Collins homeowners navigate available options, including:

  • Smart thermostats that learn your schedule and adjust temperatures automatically
  • Variable-speed motors that provide precise comfort control while reducing energy consumption
  • Advanced filtration systems that remove allergens, dust, and pollutants from indoor air
  • Whole-house humidifiers that combat Colorado’s naturally dry air
  • UV light purification that eliminates bacteria and viruses from circulating air

These technologies prove particularly valuable in Fort Collins, where outdoor air quality can vary significantly due to wildfires, agricultural activities, and seasonal pollen levels. Our installation teams ensure proper integration with existing HVAC systems, maximizing benefits while maintaining system reliability and efficiency throughout the entire Front Range region.

The investment in quality HVAC services pays dividends through improved comfort, reduced energy bills, extended equipment lifespan, and enhanced property value. Our trusted experts work diligently to deliver solutions tailored to your specific needs and budget, backed by comprehensive warranties and our commitment to customer satisfaction that has defined Northern Air for over three decades.

Denise H
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!

Marilyn W
Great company!! Our daughter’s furnace went out yesterday on the coldest day in the past 30 years! Not only did they respond promptly and replace the furnace today, they brought her space heaters last night! I highly recommend this company for their ethical practices, fair prices and commitment to our community! Thank you Nick, JJ and Brett for your help!!

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!
