Ray N. Welter Heating Company

Ray N. Welter Heating Company has provided residential HVAC services throughout the Twin Cities metro since 1904, making it one of the oldest family-owned heating and cooling contractors in Minneapolis. The company holds a 4.8-star average from 199 reviews, reflecting decades of consistent service. Its state-certified technicians serve homeowners across Minneapolis and St. Paul, handling furnaces, central air conditioners, and ductless systems. Standard hours run Monday through Friday from 8 AM to 4:30 PM, with 24-hour emergency furnace repair available for existing customers.

Welter Heating exclusively installs Trane gas furnaces and central air conditioners, a brand partnership that reflects the company's focus on efficiency and reliability. For ductless cooling needs, the team specializes in Mitsubishi systems, ideal for older homes without ductwork or for targeting comfort in specific rooms. Indoor air quality services include air exchangers, whole-home humidifiers, and central air cleaners. A $99 annual furnace maintenance tune-up helps extend system lifespan, and financing options are available for larger installations. The company does not service boilers, concentrating instead on furnaces and heat pumps for residential applications.

Customer reviews name specific technicians who solved problems other contractors could not. Ralph diagnosed and repaired Dan J.'s furnace in 30 minutes, providing a quote lower than a competitor who had suggested replacement. For Kathleen d., Phil arrived within two hours during an after-hours emergency and confirmed her aging furnace needed no replacement. Travis took time explaining options in clear language to David Johnson, an older homeowner who appreciated the honest assessment. Lex Hade's installation involved Don and Pete, who completed two new systems by 3 PM the same day and stayed to answer every question.
