Three months of heat, a full year of hail and wind
Cass County only asks a new air conditioner to run three months a year, June through August, with summer afternoons averaging 80°F. The rest of the year, the unit still sits outside, through whatever the weather does next.
The last ten years brought 109 hail events to the area and 172 damaging wind events, with hail recorded up to 2.5 inches. A condenser's coil and fan sit right out in that. Any new unit installed since 2023 also has to meet 13.4 SEER2, the federal minimum for efficiency.

North Dakota requires HVAC contractors to hold a state license.
The state tested this contractor and keeps a record of the license through the Secretary of State. That license belongs to the contractor, not to any one job, so it stands behind everything they install under it. North Dakota sets a line at $4,000. Work under that amount does not need a licensed contractor. An air conditioner installation runs past that line, so this job falls under the license.
Most cities and counties in North Dakota require a permit for an air conditioner installation, with an inspection once the work is done. That inspection is separate from the state license. It is the local building office checking the installation itself, not the contractor's standing.

- What size air conditioner does my house need?
- The right size depends on your square footage, your ceiling height, how much shade your house gets, and how well it's insulated, so there's no single number that fits every home. A contractor works this out with a load calculation, not a chart based on square footage alone. Going bigger than what the calculation calls for isn't a safety margin, it actually makes the unit cool the air fast without running long enough to pull the humidity down, so the house feels clammy even at the right temperature.
- Should I replace the whole system or just the outdoor unit?
- If your indoor coil and outdoor unit were installed together and matched for each other, replacing only the outdoor unit can leave you with a mismatched system that won't hit its rated efficiency and may not perform well. Age matters too. If the indoor coil is old, replacing it at the same time avoids paying for labor again when it fails later on. A contractor can look at both halves of your system and tell you whether they're still compatible or whether the age and condition of the coil make full replacement the better call.
- Do HVAC contractors in Fargo need a state license to work on my home?
- Yes, North Dakota requires HVAC contractors to hold a state license, and installing an air conditioner is licensed work. The license is held by the contractor, not issued per job, so you're checking the company's standing rather than looking for paperwork on the specific installation. Most cities and counties also require a permit for this kind of job, with an inspection once the work is finished, so ask whether that's being pulled as part of the installation.
