Ask what the system delivers on the winter design day.
A low-temperature operating claim is not a complete North Dakota heating design. Request the house’s calculated heat requirement at the local design temperature and the exact matched system’s output at the same condition.
Have the installer show the backup contribution and the rooms each heater serves. For a Fargo-area house and a different property farther west, use separate address-specific assumptions. Do not use a single statewide balance point or assume the old equipment’s size proves the new design.
Otter Tail’s North Dakota offer requires energy control.
Otter Tail’s North Dakota view lists $400 per ton for qualifying ductless cold-climate heat pumps and $600 per ton for ducted systems, with at least 7.5 HSPF2 and an eligible energy-control rate. Its Minnesota schedule differs.
Select North Dakota and use the 2026 North Dakota application. Ask the utility to confirm the equipment, qualifying capacity, rate enrollment, and any preapproval before counting the incentive.

Design for a control event as well as cold weather.
If your rate lets the utility interrupt or control electric heating, ask the installer to explain what maintains temperature during that event. Write down the backup fuel, capacity, automatic controls, and any required metering or wiring.
Ask for the operating estimate under that actual rate and control arrangement. A discount on electricity should be weighed alongside backup fuel use, extra installation costs, and retained-system maintenance. Have the utility confirm the rate rather than rely solely on a contractor’s description.
Keep winter readiness in the installation scope.
Require the outdoor stand, drainage, snow clearance, manufacturer’s service clearances, and accessible filter location on the plan. Ask which startup checks can be completed at installation and whether a cold-weather follow-up is included.
For a dual-fuel setup, request a control demonstration and owner instructions identifying normal heat, auxiliary heat, and a fault. Confirm who responds locally if the equipment stops and what travel or after-hours charges apply.
Use this evidence checklist to compare bids.
| Claim in the quote | Evidence to request |
|---|---|
| Whole-home heating | Load calculation and room coverage |
| Cold-weather output | Exact equipment performance table |
| Utility savings | Approved rate and backup assumptions |
| Rebate eligibility | North Dakota form and matched certificate |
| Reliable service | Named local service provider and terms |
Other North Dakota utilities and cooperatives have their own offers. Use the provider on your bill and confirm the current program before treating any incentive as part of your purchase budget.
Bring a clear project brief to your installer.
