Iowa does not give HVAC contractors a separate trade-exam license. Under Iowa Code chapter 91C, a construction contractor who earns at least $2,000 in a year must register with the Department of Inspections, Appeals, and Licensing. Registration shows the contractor filed with the state. It is not proof they passed a heating exam. Des Moines still controls the building permit. Ask who will pull it, and look the company up with DIAL before you sign. This page shows which Des Moines HVAC companies AI assistants named most often across answers RecommendRadar ran and stored, how often each appeared, and the sources those answers cited. A frequent mention reflects visibility to AI, not service quality. Get written quotes that name the equipment and warranty.
