Full-Service HVAC, Plumbing & Electrical for Johnston Homes and Businesses
Johnston sits just west of Providence, and we cover it at the edge of our range. A mix of older homes and newer subdivisions keeps our four trades busy, from heating swaps to panel upgrades. One call handles the whole house.
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 Johnston’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.
