Heavy Duty
Diesel Repair
Nelcon Towing & Recovery is North Haven’s heavy duty diesel repair shop for semi trucks, tractor trailers, box trucks, buses, and work trucks. From three repair shops on Maple Avenue, Old Maple Avenue, and State Street, our diesel technicians handle everything from engine diagnostics and complete diesel engine rebuilds to turbocharger, fuel injection, DPF, and EGR repairs, plus the routine maintenance that keeps commercial vehicles running and compliant. Fleet managers count on our on site fleet maintenance and mobile truck repair to cut downtime in Meriden, Wallingford, Cheshire, and across Connecticut. Because we also run a 24/7 heavy duty towing fleet, we can tow a disabled truck straight into our bays and start the repair right away. One call covers it all, from the side of the road to back on the road.
