Locally serving Woodbury since 2010

Northern One Hour Heating & Air Conditioning provides furnace repair, AC repair and furnace tune-ups in Woodbury, MN. We are a locally owned Twin Cities company with licensed technicians who work on all major brands, older systems included.

Woodbury heating and cooling has its own challenges. Homes here are often large, two stories plus a finished basement, and many were built tight for energy savings. That can mean uneven temperatures between floors and humidity that runs too high or too low.

We look at the whole house, not just the box in the basement. You get a technician who arrives in the window you picked, a clear explanation, and a price before any work starts. Call (763) 260-6662 or book online. We are available around the clock.

Furnace Repair in Woodbury, MN

Woodbury grew fast from the 1980s through the 2000s, and building has kept going in the southern part of the city since. Most homes here are larger two-stories with finished basements, heated by high-efficiency gas furnaces that vent through PVC pipes.

Those furnaces tend to fail in a few familiar ways. A condensate drain or trap clogs or freezes. A pressure switch keeps the burners from lighting. A flame sensor gets dirty and the furnace lights, then shuts off. In a bigger house, a weak blower can also leave far rooms cold.

We find the real cause, explain your options, and give you the price before we start. Our trucks carry common furnace parts, so many repairs are wrapped up the same visit.

AC Repair in Woodbury

In July, the question we hear most in big two-story homes is why the bedrooms upstairs will not cool. Sometimes the air conditioner is too small or failing. Sometimes the ductwork simply cannot move enough air to the second floor.

Other common AC repairs include a bad capacitor, a stuck contactor, a failing condenser fan motor, a refrigerant leak, or a clogged condensate line that shuts the system off. We check the whole system, not just the part that broke, so the fix lasts.

Furnace Tune-Up in Woodbury

A fall furnace tune-up catches small problems before a January cold snap turns them into a no-heat night. Our Essential Tune-Up is a 19-point checklist covering safety and control tests, a carbon monoxide and heat exchanger check, gas pressure, airflow, static pressure, drains and venting.

If your furnace is older or has gone a few years without service, ask about our Northern Restoration, a deeper cleaning and recalibration. Our maintenance plan keeps the visit on the calendar every year.

Comfort Beyond Heating and Cooling

Newer Woodbury homes are built tight. That saves energy, but it also traps moisture and stale air. In winter you may see fog on the windows. In other homes the air is so dry that static shocks and cracked wood floors show up.

We install whole-home humidifiers, dehumidifiers and air purification so the air in your home feels right in every season, not just the temperature.

Woodbury FAQs

Do you serve all of Woodbury? +

Yes. We serve homes throughout Woodbury and the surrounding east metro. When you call, we give you an honest arrival window for your address.

Why does my furnace keep turning on and off? +

Short cycling can come from a dirty filter, a dirty flame sensor, an overheating furnace, a thermostat problem, or a furnace that is too big for the house. A technician can test each one and find the real cause.

My windows fog up every winter. Is that an HVAC problem? +

It can be. Heavy condensation on windows usually means indoor humidity is too high for the outdoor temperature. A humidifier set too high or poor ventilation are common causes. We can check your settings and your system.

How often should I service my AC and furnace? +

Once a year for each: the furnace in early fall and the air conditioner in spring. A maintenance plan makes it easy to stay on schedule.

Will you tell me if my system should be replaced? +

Yes, honestly. If a repair makes sense, we repair it. If replacement is the better money, we show you why and walk you through financing options.

What happens if you are late? +

You pick the arrival window. If our technician does not arrive on time, you do not pay for the service. That is our On-Time Guarantee.
