Best Tankless Water Heater Dealer
Boulder’s housing presents an interesting mix for heating and cooling. Older homes and rentals weren’t always built around the cooling demands homeowners experience today, while renovations and newer construction have to account for the city’s current approach to building efficiency. That can mean very different HVAC needs from one Boulder property to the next.
Northern Air provides heating and cooling service for Boulder homes and businesses. Our work covers air conditioning, furnaces, boilers, emergency repairs, and commercial HVAC for existing buildings and new projects.
If your system is having trouble keeping your Boulder property comfortable, we can help determine what it needs. Schedule service and get your heating or cooling appointment on the calendar.

Air Conditioning Services
Air conditioning has become a bigger consideration for Boulder properties that weren’t originally designed around central cooling. The City of Boulder specifically notes that older buildings generally weren’t constructed with AC because high-heat days were less common in the past.
Northern Air provides air conditioning services for Boulder homeowners dealing with aging equipment, inadequate cooling, and homes that need a new approach to summer comfort.
-
AC Installation: Adding or replacing cooling in an older Boulder property isn’t always as straightforward as swapping equipment. Air conditioning installation can help homeowners choose a system suited to the home’s current layout and cooling needs.
-
AC Repair: A Boulder AC may perform normally during milder foothills weather and then struggle once several hot afternoons arrive in a row. Air conditioning repair can address long run times, weak cooling, and systems that no longer maintain the thermostat setting.
-
Ductless Mini Splits: Older Boulder homes, additions, studios, and converted spaces may not have ductwork where cooling is needed. Ductless mini splits give homeowners another option for conditioning those areas without trying to extend a conventional duct system through the entire property.
Get your cooling system ready before hotter Boulder afternoons expose an existing comfort problem.
Heating Services
Boulder sits directly against the foothills, and winter conditions can put furnaces and boilers into steady use. Heating needs can also differ substantially between an older Boulder house and a recently renovated or newer property.
Northern Air provides heating services for Boulder homes with forced-air and hydronic heating systems.
-
Furnace Repair: A furnace problem becomes much easier to notice when colder foothills weather has the system running throughout the day and night. Furnace repair can address weak heat, short cycling, unusual operation, and rooms that aren’t warming as expected.
-
Boiler Maintenance: Some of Boulder’s older properties rely on hydronic heating, making seasonal boiler condition particularly important before sustained winter use. Boiler maintenance gives the system attention before colder weather puts it through longer heating cycles.
-
Emergency Heating Repair: A heating failure during a Boulder cold spell isn’t something every household can comfortably put off. Emergency heating repair is available when a furnace or boiler problem requires more immediate attention.
Northern Air also has a 24/7 answering service, giving Boulder customers a way to reach us when an HVAC problem occurs outside regular hours.
Schedule heating service when your Boulder home starts showing signs that its furnace or boiler isn’t keeping up.
Commercial HVAC Services
Boulder’s commercial properties range from older buildings and renovated spaces to offices, restaurants, research facilities, retail properties, and newer construction. HVAC work often has to account for the building itself as well as how the space is used each day.
Northern Air provides commercial HVAC services for Boulder businesses, builders, contractors, and property owners.
-
New Construction HVAC: Boulder requires heating and cooling equipment sizing documentation for new residential construction, and its energy code applies to new commercial buildings as well. Northern Air handles new construction HVAC when mechanical systems need to be coordinated with the larger building project.
-
Commercial HVAC Projects: Renovating or changing the use of an existing Boulder building can create HVAC requirements that go beyond an ordinary repair visit. Northern Air handles commercial HVAC projects for planned work involving larger system changes and building improvements.
-
Emergency HVAC Services: An HVAC failure can quickly interfere with customers, employees, tenants, or normal operations in a busy Boulder commercial property. Commercial emergency HVAC services are available when the heating or cooling problem needs prompt attention.

HVAC Challenges for Boulder Homes
One of Boulder’s more distinctive HVAC issues is the relationship between its older building stock and changing cooling needs. The city reports that rental housing makes up 52% of its housing stock and specifically notes that many older buildings weren’t constructed with air conditioning because extreme heat was historically less common. That can leave some properties looking for cooling options that work with an existing structure rather than a home designed around central AC.
Renovation also brings another consideration. Boulder requires heating and cooling equipment sizing documentation for many projects involving new mechanical systems, and properties 50 years or older can face additional historic-preservation review depending on the work involved. For homeowners updating an older property, HVAC decisions may need to fit both the building and Boulder’s current requirements.
