Full-Service HVAC, Plumbing & Electrical for Charlestown Homes and Businesses
Charlestown is a coastal town in southern Rhode Island at the far edge of our range, known for its salt ponds and beaches. Seasonal homes and year-round houses alike want one company across every trade when we’re down that way.
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 Charlestown’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.
