Full-Service HVAC, Plumbing & Electrical for North Smithfield Homes and Businesses
North Smithfield sits in northern Rhode Island near the Massachusetts line at the edge of our range, home to historic Slatersville. Village homes and rural properties alike need one company for all four trades. We bring them on one truck.
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 North Smithfield’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.
