Air Conditioning Repair, Installation & Replacement
Whether your central air has stopped cooling, started leaking, or reached the end of its life, JBD HVAC diagnoses the problem first and lays out repair and replacement options side by side. We repair any brand and install and replace systems with the equipment we carry, so the decision rests on real numbers. Our work covers air conditioning repair, installation, and maintenance.
Medfield's oldest homes, including the Peak House and the Dwight-Derby House, both dating to the 1600s, were built centuries before anyone imagined central air. If you own an older home in the center of town, cooling usually starts with a conversation about ductless or another retrofit path before anyone quotes a standard duct-based system.
Air Duct Repair, Sealing & Replacement
We handle air duct repair, sealing, and replacement, along with new duct installation for additions and new construction. A technician inspects the runs for leaks, tears, and disconnected sections, repairs what can be repaired, and replaces what cannot, so conditioned air reaches the rooms it was meant for.
Capes and ranches are a familiar sight in Medfield, and in a house like that, a bedroom that never matches the rest of the floor is the classic reason to look at the ducts. An inspection is a simple first step before anyone talks about new equipment.
Boiler & Steam Boiler Repair, Replacement & Maintenance
Hot-water and steam boiler repair, maintenance, and replacement are all part of our work, and JBD HVAC installs a new boiler when yours is past repair. Whether the problem is no heat, uneven radiators, or a system that has gone years without service, we diagnose first and give you the repair and replacement figures side by side.
Medfield's straw bonnet trade started on North Street in 1801, and a house that old has seen more than one heating system come and go. If yours still heats with radiators or hot-water baseboard, a fall boiler check is far easier to schedule than a January no-heat call.
Ductless Mini-Split Installation & Repair
As a Certified Ductless Pro, we install, replace, repair, and maintain ductless systems that heat and cool one room or zone at a time. Each indoor unit connects to an outdoor unit through a narrow refrigerant line, so walls and ceilings stay intact and no ductwork is needed.
From Main Street to the roads around Noon Hill, a finished attic, a converted garage, or a new addition is often the one space the main system never reached. A single ductless unit gives that room its own thermostat without extending anything else in the house.
Furnace Repair, Installation & Tune-Ups
We repair, replace, and install gas furnaces, and we tune them up each fall. When a furnace short-cycles, blows cold air, or fails to start, we find the fault, explain it, and price the repair against replacement.
Medfield sits where Route 27 and Route 109 meet, and a furnace that quits overnight in January turns the morning drive out of town into a scramble. A fall tune-up is the easiest time to catch a worn part before it picks the coldest night to fail.
Heat Pump Installation, Dual-Fuel Systems & Replacement
We install, replace, repair, and maintain heat pumps, including dual-fuel systems that pair a heat pump with a furnace you already own. Every project starts with one decision: retire your current heating for good, or keep it as backup.
Medfield is a town of larger single-family homes, so whole-home versus partial-home is a real decision here. One setup replaces your heating and cooling, the other works alongside the boiler or furnace you already have, and Mass Save pays them differently. The questions below cover the current rebate numbers and a change coming on January 1, 2027.
HVAC Maintenance Plans & Seasonal Tune-Ups
Our maintenance plan covers gas furnaces, central air conditioners, heat pumps, and mini splits with scheduled inspections by NATE-certified technicians, who check airflow, refrigerant levels, electrical connections, and safety controls. Members also get discounted repair labor and parts, priority repair scheduling, and a waived warranty processing fee.
From summer swim days at Hinkley Pond to the first frosty mornings, Medfield's seasons turn quickly, and so does the load on your equipment. We recommend a furnace tune-up in early fall and an AC tune-up in spring, so the checks happen before the weather asks the system to prove itself.
Indoor Air Quality Solutions & Humidity Control
We install indoor air quality equipment for filtration, humidity control, and ventilation, matched to what is bothering your household, whether that is dust, allergens, odors, or air that feels damp. As an Indoor Air Quality Expert, we can talk you through which option fits your home and which does not.
A whole-home dehumidifier is a common answer when a basement feels damp in July. In a town with the Charles River along almost a third of its border, it is a fair question to ask about your own basement.
Zone Control Systems for Multi-Level Homes
We install, repair, and tune zone control systems that let different floors or wings of your home hold their own temperatures, using dampers in the ductwork and separate thermostats. If you already have zoning that has stopped behaving, we troubleshoot that too.
Larger homes tend to grow over time, with a finished attic here and a bump-out there, and the upstairs that never matches the downstairs follows. Zoning is the usual fix when one part of the house is always the odd one out, and it is worth asking about before anyone suggests adding a second system.

Medfield Heating, Cooling & Heat Pump Questions, Answered
We repair, install, and maintain heat pumps, boilers, ductless systems, and the rest of a home's heating and cooling equipment. These answers cover decisions that come up when a Medfield home mixes older heating with newer equipment.
Will a heat pump work with the radiators in my older Medfield home?
Not directly. A standard air-source heat pump, whether ducted or ductless, delivers heat as warm air, so it does not warm cast-iron radiators or hot-water baseboard. Homeowners usually take one of two paths: keep the boiler running the radiator zones and add ductless units where cooling or extra heat is needed, or move fully to a ducted or ductless heat pump and retire the radiators. Which one fits depends on the home's layout and the boiler's age and condition, and we sort that out with you on a visit.
How long does a heat pump or ductless installation take in a Medfield home?
It depends on the scope. Customer reviews on our site describe a central AC addition finished over two days and a two-heat-pump installation that took three days, with ducts and registers adjusted along the way. A single ductless unit is a smaller project, and we confirm the schedule with you before work begins.
Why is my Medfield house still cold when the heat pump is running?
A heat pump that runs for hours without catching up deserves a service call, not a higher thermostat setting. Common causes include a dirty filter or blocked outdoor unit restricting airflow, a system sized too small for the house, a defrost cycle that is not clearing, low refrigerant, or a thermostat mode that never calls for backup heat. A technician can check each of these during one visit. If your home still has a furnace or boiler, a dual-fuel setup lets that equipment carry the load when the heat pump needs help.
What does your maintenance plan include for a Medfield homeowner?
Members get scheduled inspections by NATE-certified technicians covering airflow, refrigerant levels, electrical connections, and safety controls on gas furnaces, central air conditioners, heat pumps, and mini splits. Members also receive discounted repair labor and parts, priority repair scheduling, and a waived warranty processing fee. The plan details do not list boilers, so ask us how boiler service fits in when you call.
What Mass Save rebates and financing apply to a heat pump in Medfield, and does timing matter?
Timing matters. For equipment installed in 2026, Mass Save's whole-home heat pump rebate is $2,650 per ton, up to $8,500, and rebate paperwork for 2026 installs is due by February 28, 2027. For equipment installed on or after January 1, 2027, Mass Save lists a lower whole-home rebate of $2,350 per ton, capped at $7,500. A partial-home rebate, which keeps your existing boiler or furnace in place, is $1,125 per ton up to $8,500 in 2026. The whole-home tier requires the heat pump to be your only heating and cooling source and the home to meet Mass Save's weatherization requirement, and the equipment must be ENERGY STAR Cold Climate certified and on Mass Save's qualified products list. Separately, the Mass Save HEAT Loan offers 0% financing up to $25,000 for qualifying upgrades. Program terms change, so we confirm your eligibility before quoting, and we handle the rebate paperwork and HEAT Loan application.
My Medfield home has a boiler and no ductwork. What are my options for adding air conditioning?
You have two common routes. Ductless units cool room by room with no ducts and leave the boiler untouched, which suits finished attics, additions, and homes with radiators. A ducted air handler works where there is room to run new ductwork without major carpentry. We install both and tell you which fits after seeing the house.

Customer Reviews

JBD is wonderful to work with. Always professional and responsive. We had a late day emergency and Jim was done for the day on his way home, but he detoured over to our house and made a potentially big problem really small. This was late on a Friday. JBD cares about their customers and provide quality, reliable, outstanding service at a fair price. What more can you ask for?
