AC/DC Mechanical, LLC: Watertown's Trusted HVAC Contractor and Home Services Team
Built in Watertown, trusted across Jefferson and Lewis Counties.
AC/DC Mechanical, LLC brings HVAC, plumbing, electrical, and general contracting expertise together under one local roof, so North Country homeowners never have to guess who to call.
From a Local Garage to Jefferson County's Multi-Trade Contractor
AC/DC Mechanical, LLC started with a simple idea: homeowners in the Watertown area deserve a contractor who shows up on time, knows the trade cold, and treats their house like it matters. What began as a small HVAC contractor operation out of Watertown has grown into a full-service company handling heating and cooling services, plumbing, electrical work, and general contracting for the entire region.
Winters here are long and unforgiving, and lake-effect snow off Lake Ontario doesn't wait for a convenient time to knock out a furnace. That reality shaped how we built this company: fast response, dependable trucks, and technicians who cross-train across trades so one call solves the problem instead of three.
Today, from our base in Watertown, NY we serve homeowners throughout Jefferson County, Lewis County, and the surrounding river and lake communities, still guided by the same standard we started with.
Our Mission and the Values Behind Every Job
Our mission is straightforward: keep North Country homes comfortable, safe, and functioning, no matter the season or the trade involved. We measure success by whether a customer's furnace fired back up, their pipes stopped leaking, or their lights came back on, not by how busy our schedule looks.
That mission runs on a few core values our team carries into every job:
- Honesty first. We diagnose the real problem and quote it straight, no upselling.
- Local accountability. We live and work here, so our name follows us into every home we service.
- Cross-trade expertise. From furnace repair to electrical panel upgrades, our team is trained across disciplines.
- Fast response. Emergency HVAC services and emergency plumbing calls get answered like emergencies.
- Craftsmanship. Every installation, repair, and remodel is built to last through Northern New York winters.
- Respect for your home. Clean work, clear communication, and no surprises on the invoice.
Why homeowners choose us
What Sets AC/DC Mechanical Apart as an HVAC Contractor and More
Homeowners across Watertown, Carthage, and the Thousand Islands region choose AC/DC Mechanical, LLC because we solve problems most contractors send elsewhere. Below is what that looks like in practice.
One Company, Every Trade
Instead of juggling separate contractors for heating, plumbing, electrical, and general contracting services, homeowners get one team that already knows the house.
Reliable Even in a North Country Winter
Emergency heating repair and emergency electrical services don't run on a nine-to-five schedule, so our trucks and crews are ready when temperatures drop below zero.
Skilled Trades, Real Certifications, Craftsmanship That Lasts
Every technician who walks into a customer's home carries real training behind them, not just a work order. Our team handles everything from furnace installation and boiler repair to electrical wiring and rewiring, and each trade specialist keeps current on code changes and manufacturer requirements for the equipment we install.
That licensing covers residential HVAC services, commercial HVAC services, plumbing installation, and electrical troubleshooting alike, which means a homeowner calling for a ductless mini split repair gets the same certified standard as a business calling for commercial property maintenance.
Craftsmanship matters just as much as credentials. Whether we're running gas piping, upgrading an electrical panel, or completing a bathroom remodeling project, we finish the job clean, code-compliant, and built to hold up through another Jefferson County winter.
Rooted in the North Country
Committed to Jefferson and Lewis County Communities
AC/DC Mechanical, LLC didn't set out to become a regional name, it grew that way because neighbors kept calling neighbors. From Watertown to Carthage, Lowville to Sackets Harbor, and out to Wellesley Island and Cape Vincent, our trucks cover a lot of ground because the North Country is home.
We know the older housing stock around downtown Watertown, the lake-effect exposure near Chaumont and Henderson, and the seasonal demands of camps and cottages along the St. Lawrence River. That local knowledge shapes how we approach every furnace services call, drain services repair, or general contractor project.
Supporting this region also means showing up beyond the job site, whether that's snow removal services for a senior neighbor's driveway or lending expertise to a local project. Jefferson and Lewis County are where we live, and it shows in how we work.
