Nine months of heat, and nights that drop to 1 below
In Leeds, a furnace runs from September through May. That is nine months out of the year the burner has to work, and on winter nights that average 1°F, it works hard. A furnace sized and installed for this climate has to keep up with that cold night after night, not just handle a mild snap.
Most homes here heat with propane, and a new furnace has to be matched to that fuel and installed to burn it correctly. Any non-weatherized gas furnace built now has to reach at least 80 percent AFUE, so that efficiency comes standard. What matters more in Leeds is whether the new unit is sized right for nine months of real cold, not just the coldest week.

North Dakota requires HVAC contractors to hold a state license.
The state license comes from the Secretary of State, and it is tied to the contractor, not to any single job. The same license has to cover this installation and the next one. North Dakota does carve out an exception for small jobs. Work under $4,000 does not need a licensed contractor. A furnace installation runs well past that line, so this is licensed work.
Most cities and counties in North Dakota also require a permit for a furnace replacement, along with an inspection once the work is finished. That permit and inspection are separate from the state license. The license covers the contractor. The permit and inspection cover this particular furnace, in this particular house.

- What size furnace does my house need?
- The right size comes from a load calculation, not a guess based on square footage. A contractor measures your walls, windows, insulation and layout and works out how much heat your house actually loses on a cold night. Too big and the furnace short cycles, turning on and off without running long enough to heat evenly. Too small and it runs constantly and still can't keep up. With winter lows here averaging 1°F, getting this number right matters more than it would somewhere milder.
- How do I know it's time to replace my furnace?
- Age is the first thing to check. Furnaces built since November 2015 have to hit at least 80 percent AFUE, so an older unit running below that is burning more fuel than it needs to for the same heat. Watch for repairs that keep coming back, a furnace that struggles to keep the house even, or a rise in your propane bill with no other explanation. Homes here need heat from September through May, nine months of the year, so a furnace on its way out shows itself fast. If yours is old and the repairs are stacking up, it is worth replacing before it fails on a night near zero.
- Is a high-efficiency furnace worth it?
- It depends on how many months your furnace runs and what it costs you in fuel. Here, that's nine months a year, September through May, with winter nights averaging 1°F, so a furnace is doing real work most of the year. A high-efficiency model burns less propane for the same heat, and with 59.3 percent of homes here heating with propane, that difference adds up over a long season. A contractor can walk through the options and price out what fits your house.
