James G Dimopoulos

5,647 permitted projects. That is the scale of James G Dimopoulos's business — an HVAC and mechanical contractor working out of Haverhill, with about 2,138 of those permits pulled in the past three years. Heating and cooling is the bulk of it: 1,897 of the permits are HVAC work, with home additions, commercial renovations and fences filling out the rest. The typical permit runs around $4,565. BuildZoom's own scoring puts him at 108, which it places in the top 5% of the 139,240 licensed contractors it tracks in Massachusetts. BuildZoom lists a Massachusetts home improvement contractor registration, #167375, and a construction supervisor licence, #CS-104464, under his name. Check both numbers on the state's licence register before you sign anything. For a homeowner around Haverhill who needs a furnace or an air conditioning system replaced by someone who does that work day in and day out, he is a sensible call. Get the equipment model, the sizing and the warranty terms in writing, and ask for a couple of recent addresses nearby where the same system went in.
