Thank you for reaching out. A member of our team will contact you shortly.

A lasting repair starts with understanding how the system is installed and what has failed. A new installation takes a different kind of planning: the capacity, connections and access must suit the property. Proto Home Service Plumbing & HVAC provides both, along with maintenance for the plumbing and mechanical systems already working in your building.

We serve homes, businesses and managed properties across Boston and the South Shore. A single household may need a leaking fixture repaired; a property manager may need work coordinated around tenants and a shared water shutdown. We discuss those requirements before setting the scope, so you understand the work and its effect on the property.

40 Years of Industry Experience

Our licensed and insured team brings experience with existing installations, replacement projects and the connections between building systems. We assess what is present rather than assume the newest equipment or the largest repair is the right answer.

One Company for Connected Systems

A boiler, water heater and plumbing system can share more than a room. When a project crosses service categories, we account for the related piping and equipment so the proposed work fits together.

Clear Findings and Upfront Pricing

A recommendation should be understandable. We explain the identified problem, the proposed work and any relevant repair or replacement choices, giving you a defined scope and price to review before proceeding.

A 100% Workmanship Warranty

We stand behind the plumbing and HVAC repairs and installations we complete with our workmanship warranty. We explain the coverage applicable to your service and how it differs from any separate equipment-manufacturer warranty.
