Full-Service HVAC, Plumbing & Electrical for Woonsocket Homes and Businesses

Woonsocket sits at the far northern edge of Rhode Island on the Massachusetts line, and we reach it at the outer edge of our range. The city’s dense historic housing keeps our four trades busy. One company for heating, cooling, plumbing, and electrical.

Here’s what sets us apart. Triangle runs four trades under one roof: heating and cooling, plumbing and water, electrical and generators, and commercial refrigeration. Most outfits around here do one. Maybe two. We do all four, which means one call, one crew, and one invoice for the whole property instead of chasing three contractors who each blame the other.

New England winters are hard on houses, and a lot of Woonsocket’s homes have been around a while. Aging boilers. Electrical panels that can’t keep up with a modern home. Plumbing that’s original to the house. We know this housing stock cold, because our techs have been working on homes just like these for 50 years.
