Plumbing & HVAC in Cohasset, MA
Cohasset is a beautiful place to own a house and a punishing place to own mechanical equipment. Salt carried off the harbor and in off Jerusalem Road eats outdoor condensers, coils and fasteners faster than anywhere else we work. If your last outdoor unit died early, this is usually why.
No heat, no hot water, or an active leak in Cohasset? Call (781) 974-5239 — a real person answers around the clock, and we’re minutes away from our Norwell shop.
What We See in Cohasset Homes
Every town’s housing stock has its own patterns. These are the ones our trucks are stocked for in Cohasset.
Salt air corrosion
On exposed coastal properties we spec coated coils and corrosion-resistant hardware, place units out of direct spray where we can, and show you a simple freshwater rinse schedule that meaningfully extends equipment life.
Limited natural gas
Gas doesn’t reach every Cohasset street. Many homes run on oil or propane, which makes cold-climate heat pumps a strong fit for both comfort and operating cost.
Well water in spots
Hardness and iron show up in fixtures and appliances long before anyone thinks to test the water. Filtration and softening fix it at the source.

Rebates for Cohasset Homeowners
Cohasset homeowners are generally eligible for Mass Save heat pump and weatherization incentives.
