What we handle
A Multi-Trade HVAC Contractor Built for North Country Homes
Winters along the Black River and out toward Lake Ontario are not gentle on furnaces, boilers, or old wiring. Homeowners across Jefferson and Lewis County call AC/DC Mechanical because we cover the full range of home systems, from furnaces and air conditioners to water heaters and wiring, instead of sending them to three different companies for one problem.
Our technicians handle everything from furnace repair and air conditioning installation to plumbing repair, electrical troubleshooting, and general contracting services. That means the same crew that fixes a leaking water heater can also upgrade your electrical panel or frame out a bathroom remodel, with no gaps in communication between trades.
We built AC/DC Mechanical around a simple idea: homeowners deserve a contractor who shows up, explains the problem honestly, and stands behind the fix. That approach has made us a go-to hvac contractor, plumbing contractor, and electrician for families and property owners from Watertown to Gouverneur.

Every technician on our team is licensed for the trade they perform, whether that is air conditioning repair, electrical repair, or water heater installation. You get work that passes inspection and holds up long term.
Local Crews Who Know the Territory
Based right on Moffett St in Watertown, we know how a Tug Hill snow load affects a roofline, why lake-effect humidity matters for ventilation services, and which older neighborhoods still run galvanized pipe. That local knowledge shapes every job we take on.
