Tri State Supply - Adrian's Professional HVAC Repair

We supply a comprehensive range of heating and air conditioning parts and equipment for both residential and commercial systems. Our specialty is custom ductwork fabrication, tailored to your specific project needs. It's important to note we are strictly a parts supplier and do not offer installation, repair, or maintenance services.

Radiator heating imbalance is a common issue in older Adrian homes, often related to trapped air or faulty valves. We carry radiator air vents (like automatic or manual bleed valves), thermostatic radiator valves (TRVs) to control flow, and replacement zone valves. For a proper diagnosis and to ensure you get the correct part, we recommend consulting with or having your HVAC technician visit us.

With three generations of hands-on experience in the HVAC field, our team understands not just parts, but how they function in real-world systems. This depth of knowledge allows us to help identify the right component for your specific make and model, troubleshoot common issues over the counter, and provide guidance for both professionals and knowledgeable homeowners in the Lenawee County area.
