Toennies Service Co

At Toennies Service Co, we help homeowners in Damiansville, Illinois, maintain a comfortable indoor climate throughout the year. We are a local, family-owned team with more than 38 years of HVAC industry experience. From our location at 219 E Main St., we provide heating, cooling, and geothermal solutions, along with 24/7 emergency HVAC service when urgent problems arise.

We install new heating systems and repair existing equipment, including gas furnaces and heat pumps. Whether you need help restoring your current system or selecting new equipment, our technicians are ready to assist. Manufacturer’s warranties are available on new equipment. We focus on quality equipment performance, careful installation, dependable service, honest business practices, and high standards on every job.

Geothermal heating and cooling is one of our specialties. We install geothermal heat pump systems for existing homes and new buildings, helping customers maintain a steady indoor temperature through changing seasons. For a new construction project, we can make the geothermal system part of the HVAC plan and install it to provide control over the building’s indoor climate. Because the building envelope affects system performance, we recommend making it as tight as possible. Geothermal heating systems are also highly energy efficient, making them an option for keeping indoor spaces warm during cold weather. As a Geo Pro Master Dealer, we pair quality equipment with highly trained technicians, extensive experience, solid dedication, and a commitment to outstanding installation quality.
