— Local Service for Medfield Homes —
Medfield includes historic properties around Main Street and the town center, postwar Capes and ranches near Summer and Pine Streets, later subdivisions, and newer or expanded single-family homes across town. That range creates different plumbing and comfort needs, from older piping and boiler heat to multi-zone furnaces, central air, heat pumps and high-demand hot-water systems serving expanded floor plans.
Proto Home Service Plumbing & HVAC repairs, maintains and installs plumbing, boilers, furnaces, oil burners, air conditioners, heat pumps and water heaters. We diagnose the existing system, explain repair and replacement choices, and provide the approved price before work begins.

— Repairs, Drains & Installations —
A hidden leak, recurring drain problem or failed sump pump can damage finished basements and surrounding materials before the full extent is visible. Our plumbers follow the symptoms through the connected piping, explain the cause and identify whether cleaning, repair, replacement or a closer inspection is warranted.

Proto Home Service Plumbing & HVAC repairs pipes, valves, toilets, fixtures, disposals, drains, sump pumps and gas lines and installs plumbing for kitchens, bathrooms and additions. For water or sewer concerns, we help distinguish the home’s plumbing and service connection from infrastructure managed by the Town of Medfield.

— Comfort Through Every Season —
Large Medfield homes and properties enlarged over time can develop uneven temperatures when the equipment, ducts or zones no longer match the current layout. We inspect the equipment, airflow or circulation, controls and distribution before recommending repair, balancing, zoning or replacement.
• Heating Repair
• Heating Maintenance
• Heating Installation & Replacement
• Cooling Services
• 24/7 Emergency Heating
Our technicians service complete HVAC systems and explain whether maintenance, repair, balancing, zoning or replacement is the practical next step. Installation planning accounts for the house, existing distribution and the spaces the equipment must serve.
— Gas & Oil Heating Expertise —
A furnace that locks out, ignites slowly, cycles repeatedly or leaves distant rooms cold needs more than a quick parts swap. Our team services gas furnaces and is licensed in Massachusetts to work on oil burners.
• Furnace Repair & Maintenance
• Furnace Installation & Replacement
• 24/7 Emergency Furnace & No-Heat Service
We check the furnace or oil burner with its controls, safety devices, venting and distribution before discussing repair or replacement. New equipment is selected around the home’s load, fuel, venting, airflow and existing zones.
Related homeowner guide: What to check when a furnace stops working.
— Steam & Hot-Water Heat —
Medfield’s older homes and later additions may rely on steam radiators, hot-water baseboard or several hydronic zones. Cold rooms, noisy pipes, pressure changes and leaks can begin at the boiler or elsewhere in that distribution system. Proto Home Service Plumbing & HVAC works on steam and hydronic heating configurations.
• Boiler Repair & Maintenance
• Boiler Installation & Replacement
• 24/7 Emergency Boiler & No-Heat Service
We evaluate the boiler and the way heat moves through the house as one system. Repair can preserve dependable equipment; replacement may make sense when safety, condition, repeated failures or renovation goals justify a different system.
— Central & Ductless Cooling —
Central air that once served a smaller house may struggle after an attic, sunroom or other living space is finished. The cause can involve equipment, airflow, duct design, refrigerant, condensate drainage, controls or zoning.
• Air Conditioning Repair
• Air Conditioning Maintenance
• Air Conditioning Installation & Replacement
• 24/7 Emergency Air Conditioning
We diagnose weak airflow, warm air, short cycling, condensate trouble, unusual sound and room-to-room temperature differences. For replacement or new cooling, we consider the home’s load and distribution needs rather than assuming larger equipment will solve the problem.
Related homeowner guide: How AC maintenance supports performance.
— Heating & Cooling in One System —
Heat pumps can provide heating and cooling for a complete Medfield home, a new addition or rooms that are difficult to connect to existing ductwork. They can replace older equipment or operate alongside a boiler or furnace when that configuration better fits the property.
• Heat Pump Repair
• Heat Pump Maintenance
• Heat Pump & Ductless Installation
• 24/7 Emergency Heat Pump Service
Medfield promotes weatherization and heat-pump adoption through its climate program. Proto Home Service Plumbing & HVAC participates in the Mass Save Heat Pump Installer Network and can design qualifying systems, while homeowners should confirm current eligibility and requirements through Mass Save’s official heat-pump information.
— Reliable Hot Water —
A large household can expose a water heater that recovers too slowly or was never sized for current demand. Leaking, rumbling, temperature swings and tankless error codes each point toward different equipment or plumbing problems. We evaluate the appliance, controls, venting and water connections before recommending repair or replacement.
• Water Heater Repair
• Water Heater Maintenance
• Water Heater Installation & Replacement
• Tankless Water Heater Services
• 24/7 Emergency Water Heater Service
Replacement planning considers household demand, available space, venting, fuel or electrical capacity and any connection to a boiler. Proto Home Service Plumbing & HVAC works with tank, tankless and compatible indirect systems and is a Navien Service Specialist.

— TESTIMONIALS —
Peri is awesome. He is extremely responsive and did an excellent job on our bathroom renovation. I recommend going with him and I will be using him for all our plumbing needs in the future.
The service was great. I called Peri from Proto Home Sevice Plumbing for a clogged kitchen sink. After inspecting some pipes connectors/drainage, he realized that some connections were wrong. He took the time to explain everything in detail that needed to be changed. I followed his recommendations and I'm very happy with the results. Peri is very professional with many years of experience. Highly recommend!!
Peri was amazing! He was super informative and gave me an estimate right off the bat. The service was fast and the price was very reasonable. I will definitely be using Proto home service again!
Clean, professional work. They were quick to respond and took the time to explain the new tank’s operation. We had an oil hot water tank replaced (which most plumbers cant/wont do). Great work. Thank you.
I recently had Peri from Proto Home Service Plumbing handle all the plumbing work for my bathroom renovation, and I couldn't be more impressed! He installed a brand new walk-in shower, infinity drain, toilet, and faucet with absolute precision and care. What stood out most was the excellent quality of his work combined with his professional attitude and very reasonable rates. Throughout the entire project, Peri demonstrated exceptional skill and attention to detail...
Our water heater gave out unexpectedly. Peri and his team were there in less than 18 hours to replace it. He is very responsive and he will always be my first call when anything plumbing or heating needs attention.
These guys are AMAZING. If you’re looking for someone who is both knowledgeable and super-responsive, these are your guys. They have dealt with some super janky plumbing for me in a couple of old buildings and they did a phenomenal job. Trustworthy and reasonably priced. Hard combination to beat.
