Burleigh County had 17 hail days and 23 days with damaging thunderstorm winds from 2020 through 2025, according to NOAA storm records. The largest hail reported was 4.5 inches across. Hail flattens the thin aluminum fins on condenser coils and cuts airflow. After a big storm, take a look at the outdoor unit; homeowners insurance often covers the damage. Burleigh County also had 3 tornado days in that period. In Bismarck, 18.7% of residents are 65 or older. For older adults, a house with no heat in January or no AC during a heat wave is a medical risk. Mention it when you call, since many companies put those calls first.

North Dakota Permits, Efficiency Rules and Rebates
North Dakota falls in the DOE's North region. New split central air conditioners must meet at least 13.4 SEER2, and heat pumps sold anywhere in the U.S. need 14.3 SEER2 and 7.5 HSPF2. Equipment replacements in Bismarck generally need a mechanical permit, and a reputable contractor will pull it for you. Ask for their North Dakota license or registration number and a certificate of insurance with the quote. The federal 25C tax credit ended for equipment installed after December 31, 2025, so incentives now come mostly from utilities and state programs. Check your electric and gas utility's rebate page before you pick equipment.
Before You Hire
- Most mini-splits qualify for utility heat pump rebates, so check before you buy.
- Multi-zone systems cost more per room, but they run off a single outdoor unit.
- If winter nights regularly drop below 10°F, pay for a cold-climate model.
