Nine months of heat, five below at night
Your furnace in Lisbon runs from September through May. On winter nights averaging 5°F, it cycles on and off for hours at a stretch, and every start puts load on the igniter and the blower motor. When one of those wears out, you will notice fast, because there is no mild stretch to coast through. Summer asks less of the system, three months with afternoons near 80°F, but the compressor still has to work when you finally do call on it.
Almost half the homes here heat with electricity, so a power outage means no heat at all, not just a cold house waiting on gas. Ransom County has logged 54 winter storms and 46 damaging wind events over the past ten years, and statewide, 7 percent of households lost power for a full day or more last year. When the lines come back up, most systems restart on their own. If yours does not, that is worth a call.

North Dakota requires HVAC contractors to hold a state license.
North Dakota tests and records HVAC contractors through the Secretary of State. The license belongs to the contractor, not to any one job, so the same license covers a small repair and a full install alike. North Dakota does carve out an exception. Work under $4,000 does not need a licensed contractor.
A repair on a heating and cooling system can land on either side of that line. Where the job is licensed work, that state license is what stands behind whoever does it. Where the job falls under the $4,000 threshold, North Dakota does not require a license for it, and nothing else in the state steps in to cover that gap.

- Why is my heat not working?
- Start with the thermostat. Make sure it is set to heat and set a few degrees above room temperature, and check that it has power if it runs on batteries. If the thermostat looks fine, check the breaker for the furnace, since a tripped breaker will shut the whole system down. A furnace that won't light at all often has a bad igniter or a flame sensor that needs cleaning, and either one is a job for a licensed contractor. With winter nights here averaging 5°F, a furnace that's short-cycling or blowing cold air needs attention fast, so don't wait on it.
- Why is my system running but not cooling the house?
- Check the air filter first. A filter clogged with dust blocks airflow across the coil, and that alone can stop a system from cooling even though it's running fine. Next check the outdoor unit and clear away any leaves, grass clippings, or debris sitting against it, since it needs open airflow to release heat. If the filter is clean and the outdoor unit is clear but the house still isn't cooling on an 80°F afternoon, the system may be low on refrigerant or have a failing part, and that calls for a licensed contractor to diagnose.
- What can I check before calling for HVAC repair?
- Check the thermostat settings, the batteries in it if it has any, and the breaker for the system. A tripped breaker or a thermostat set to the wrong mode causes more no-heat and no-cool calls than people expect. Check the air filter too, since a dirty one restricts airflow and can make a system struggle even when nothing else is wrong. If those all check out and the system still isn't working right, the problem is inside the equipment, and a licensed contractor will need to look at it and price the repair for your system.
