Nine months of heat, and nights near 3 below
Velva needs a working furnace from September through May. That is nine months out of the year, and on the coldest nights the average low is 3°F. A new furnace here has to hold up to a long, hard season, not just take the edge off a few cold snaps.
McHenry County has also seen its share of winter storms, 30 of them over the past ten years, along with 41 damaging wind events. Power can go out with the cold still coming down, and across North Dakota 7 percent of households lost power for 24 hours or more in 2024. Any new gas furnace installed today has to meet a federal minimum of 80 percent AFUE, so the equipment going in is required to burn more efficiently than what many homes still have running.

North Dakota requires HVAC contractors to hold a state license.
That license means the state tested this contractor and keeps a record of who holds one. It covers the contractor as a whole, not this one job, so it stands behind everything they install. North Dakota also draws a line at $4,000. Work under that amount does not need a licensed contractor at all.
A furnace installation costs well past that line, so the license is what backs this job. It does not replace the local building office. Most cities and counties still require a permit for a furnace swap, with an inspection once the work is done, and that inspection is what checks the gas connection and venting were done right.

- What size furnace does my house need?
- It depends on your square footage, your insulation, your windows, and your home's layout, so there's no single number that fits every house. A contractor works this out with a load calculation that looks at all of that together. Getting it right matters here, since winter lows around 3°F mean an undersized furnace will struggle to keep the house warm and an oversized one will short cycle and wear out faster. Don't assume the old furnace was sized correctly. Have a contractor calculate it fresh.
- How do I know it's time to replace my furnace?
- Watch for uneven heat, repair costs that keep climbing, or a furnace that runs constantly without keeping the house warm. Homes here need heat from September through May, so a furnace that's struggling won't hide it for long. If you're calling for the same repair more than once in a season, that's usually the sign to stop patching and start planning a replacement. A contractor can tell you whether what you're seeing is normal wear or the start of a bigger failure.
- Is a high-efficiency furnace worth it?
- It depends on how long you plan to stay in the house and how much the furnace runs each year. With heat needed here from September through May and winter nights averaging 3°F, a furnace in this area logs a lot of hours, so higher efficiency has more months to make a difference. Every new non-weatherized gas furnace sold today has to reach at least 80 percent AFUE by law, and high-efficiency models go beyond that. A contractor can walk through the difference in equipment and venting for your specific house, since high-efficiency furnaces vent differently than standard ones.
