A system built for nine months of heat and two of cooling
Watford City needs heat from September through May, nine months of the year. Winter nights average 7°F from December through February, and a new furnace has to hold up to that cold night after night, most of the calendar through. Summer is shorter and milder by comparison, with afternoons averaging 81°F across July and August, but a system here still has to cool a house on those days.
Most homes in this area heat with electricity, and the power does not always stay on. McKenzie County has logged 16 winter storms and 79 damaging wind events over the past ten years, and statewide, 7% of households went at least 24 hours without power in 2024. A furnace and air conditioner going in here are going into a place where the weather is part of the job, not an exception to it.

North Dakota requires HVAC contractors to hold a state license.
The state license is held by the contractor, not tied to this one job, so the same license covers whatever work they do for you next. In North Dakota that requirement drops away below $4,000, so a small repair can fall outside it, but a full heating and cooling installation runs well past that line and needs a licensed contractor.
On a job like this, the license is what stands behind the work, but it is not the only check. Most cities and counties in North Dakota require a permit for a system installation like this, along with an inspection once the work is finished, so someone from the local building office looks at the completed job independent of the contractor who did it.

- When should I replace my HVAC system?
- Replace it when repairs get frequent, or it can't keep up on the coldest nights anymore. Here winters push down to 7°F on average from December through February, so a furnace that struggles to hold up in that cold is worth replacing before it fails outright rather than after. A system running fine with no repeat problems is usually worth repairing instead. If you're paying for a second or third repair in a year, that's the sign to start pricing a replacement.
- Should I replace my furnace and air conditioner at the same time?
- If both are old and giving you trouble, yes, it's worth doing together. A furnace and air conditioner installed at the same time are matched to work as one system. Homes here need heat nine months a year against two months of cooling, so the furnace carries most of the load and its condition matters more. If your air conditioner is still working well and only the furnace is failing, replacing just the furnace is fine. A contractor can look at the age and condition of both and tell you whether pairing them makes sense for your house.
- What happens during an HVAC installation?
- A contractor removes the old furnace and air conditioner, sets the new units in place, and connects them to your ducts, gas line or electrical circuit, and refrigerant lines. They check whether the ductwork matches what the new equipment needs to move air properly and make adjustments if it doesn't. Once everything is connected, they test the system to make sure it runs the way it should. In most cities and counties this job needs a permit from the local building office and an inspection when the work is done, and North Dakota requires the contractor doing the work to hold a state license.
