ServiceOne Heating, Cooling, Plumbing, and Electrical

For more than 30 years, we’ve helped homeowners and businesses in Dubuque with essential repair and installation services. Since 1989, our mission has been to offer “One Simple Solution” by bringing heating, cooling, geothermal, plumbing, drain, electrical, generator, and indoor air quality services together under one roof. Whether a customer needs a new air conditioner, a sewer line inspection, an electrical upgrade, or help with a geothermal system, we make it easier to work with one familiar local team.

Our work is completed by our own team of 55–60 licensed, bonded, and insured technicians rather than subcontracted to outside contractors. This approach helps us maintain accountability and provide a consistent experience from the first call through the completed service. Our technicians evaluate each situation, explain the available options, and provide straightforward pricing before work begins. We handle everyday repairs as well as major installations for residential and commercial customers, with responsive scheduling and careful attention to quality, safety, and long-term performance.

As a locally owned service provider, we’re deeply connected to the Dubuque Metro Area. Our home warranty program is supported by the same in-house technicians who perform our other services, providing a local alternative to plans that depend on third-party contractors. We’re also proud members of the Better Business Bureau and recipients of the BBB Silver Award of Distinction for ethical business. From our location at 1840 Radford Road in Dubuque, we remain committed to honest communication, dependable workmanship, and making it simpler to keep homes and businesses safe, efficient, and comfortable.
