Absolutely. Furnace ignition problems in our harsh Sioux Falls winters are often related to control system issues or improper combustion air balance. Our G & R Controls division can diagnose and repair faulty ignition controls or building automation signals, while our Balancing Professionals, Inc. team ensures your ventilation and combustion airflows are correctly set for reliable, safe operation in extreme cold.

Our process is designed to maximize system efficiency from start to finish. We provide high-efficiency HVAC equipment, design and install precise building automation controls to manage energy use, and perform certified testing and balancing to ensure everything operates as intended.
