Since our inception back in 1969, API of NH & Delta T has prided itself on delivering not only quality services you can depend on but also the best value in heating, cooling, and hydronic heating products. This philosophy, combined with our belief that our products are sold through professional heating, and cooling, and maintenance contractors, has helped us grow into an industry leader. Here at API of NH, our customers both enjoy and take advantage of our totally automated Sheet Metal Manufacturing Shop, (one of the largest in New England) it turns out such sheet metal products as ducts, spiral pipe and fittings, all done accurately to your exact specifications. And a fast turn around is something we pride ourselves in, thus our contractors have no need to stock even common items in their own shop. Using API's sheet metal service is like having your own fully stocked warehouse.

These days people rely on electricity more than ever, but it does not take much for power to be disrupted. Even a short power outage leaves you without the creature comforts we all take for granted. And a power outage after a major storm? It could last weeks, making it more than just an inconvenience.
