Expert Indoor Air Quality Solutions

Considering that most people spend 90% of their time indoors, air quality is extremely important. The EPA rates air pollution among the top five urgent environmental risks to public health. Difficulty sleeping, headaches, flu-like symptoms, bloody noses, chapped lips, frizzy hair, dry skin, static shock, damage to wood furnishings, and mold growth are all consequences of degraded air quality. Improving air quality is simple and cost-effective, helping to not only protect the health, cleanliness, and condition of your home, but benefiting HVAC performance as well.

Why Choose Northern Air for Indoor Air Quality?

Indoor air concerns can come from several sources, including airborne particles, low humidity, HVAC operation, and conditions inside the home. Northern Air takes the time to identify what may be affecting your indoor environment before recommending equipment.

  • Testing before recommendations: Our AIR ADVICE monitoring system gives us information about conditions inside your home so recommendations can be based on what we find.

  • Whole-home equipment options: We install air quality products that work with the HVAC system, providing an alternative to relying on individual portable units throughout the house.

  • Solutions for Colorado’s dry air: Northern Air installs whole-home humidifiers that can help manage indoor moisture during Fort Collins’ dry heating season.

  • Multiple air purification options: We work with products from Lennox, NuCalgon iWave, and RGF HALO, giving us several options when evaluating air purification needs.

  • HVAC knowledge behind the installation: Because indoor air quality equipment often connects directly to heating, cooling, and duct systems, our HVAC experience helps us account for how a product will integrate with existing equipment.

Find Out What’s Affecting the Air in Your Home

You don’t have to guess which indoor air quality product belongs in your HVAC system. Northern Air can evaluate your concerns, discuss available options, and recommend an approach based on your home’s indoor environment and existing equipment.
