Climate Design Heating & AC LLC

Climate Design Heating & AC LLC is a Haverhill HVAC and mechanical outfit that advertises heating and cooling work, general mechanical work, and sheet metal fabrication. It is listed as a member of the Haverhill Chamber of Commerce. Beyond that, the public trail is thin: no customer reviews, and no permitted projects attached to the business on BuildZoom. The licensing entry is the part to sort out first. BuildZoom shows a Massachusetts license, #2600, with an expiration date of May 1, 2008, and says it confirmed the license was still expired in February 2025. The page is inconsistent about what that number covers — HVAC/mechanical contractor in one place, plumbing business in another — and it notes the status was cancelled at one point. That kind of record can mean the business re-registered under a different number, so the useful move is to ask for the current license and check it against the Commonwealth's E-Licensing board yourself. HVAC work touches gas, refrigerant and electrical connections, so the license question isn't a formality. Before booking a furnace, boiler or AC job, ask for the current license number, certificates of liability and workers' comp insurance, and references from recent installs.
