Nagel Heating & Air Conditioning LLC

Nagel Heating & Air Conditioning LLC has earned a perfect 5.0-star rating across 23 verified customer reviews in Stewartville, Minnesota. Operating as a family-rooted HVAC contractor, the company handles heating and cooling installations, repairs, and maintenance for residential and light commercial customers throughout the region. Their standard business hours run Monday through Friday from 8 AM to 5 PM, with availability for same-day emergency service calls when systems fail during extreme Minnesota weather.

What distinguishes Nagel Heating & AC from larger regional operators is their commitment to service agreements, annual maintenance plans that keep equipment running efficiently and help homeowners avoid unexpected breakdowns. The company also handles radon mitigation, an often-overlooked health concern in Minnesota homes, and services boilers including infloor heating systems and water heaters. Their technicians regularly work on specialty applications that other contractors decline, including air conditioners in trailer homes, demonstrating technical adaptability and willingness to tackle non-standard jobs.

Customer reviews repeatedly highlight two technicians by name, Craig and Ryan, who arrive same-day when called. Multiple homeowners describe calling on 90-degree summer days or during heat waves and finding the team could schedule them immediately, sometimes the same day, when competitors were booked four days out. Reviewers note fair pricing, honest assessments, and the ability to diagnose problems within minutes, with one customer specifically praising their willingness to work on trailer home systems when most companies refused the job.
