Furnace installation, furnace repair, boiler repair, and heat pump services designed for the long, cold stretches that define winter in this part of Jefferson County.
Calcium's mix of older farmhouses, newer builds tied to Fort Drum growth, and a handful of small commercial spots along Route 26 means no two service calls look the same. We've replaced furnaces in homes that have stood since before the hamlet had its own fire district, and we've wired up ductless mini split systems in additions built just last year.
Being minutes from the Fort Drum main gate also means quick response matters. Military families on tight PCS timelines need HVAC and plumbing work done fast and done correctly, and we build our scheduling around that reality.
We're based out of Watertown on Moffett St, just a short drive down Route 26, so getting a technician to Calcium doesn't mean a long wait when your furnace quits on a January night.

Our Watertown location keeps drive times short, which matters when emergency heating repair or emergency plumbing can't wait until tomorrow.
We handle HVAC services, plumbing services, electrical services, and general contracting services, so you're not juggling separate companies for one house.
We explain what needs fixing and why before any work starts, so Calcium homeowners never feel blindsided by a bill.
Calcium's housing stock ranges from decades-old properties near the hamlet center to newer construction built to house growing Fort Drum families, and each type comes with its own set of demands.
