When a furnace stops in the middle of the night or an AC struggles through a humid July, the answer is the same: call, describe what the system is doing, and get a price before anyone is dispatched. We handle heating and cooling work across Medway and the surrounding area, from a single-room ductless install to a full boiler replacement in an older colonial. The price is confirmed on the phone before the visit is scheduled, and the technician who comes out explains the diagnosis before any repair is authorized.
Medway is a town of older homes, many of them built before central air was standard and some still running on the original heating equipment. That shapes the work. Boiler service, oil-heat conversions, and ductless mini-split installs for rooms that were never ducted make up a significant share of what we handle here. Homeowners managing a system that has never had a tune-up, and property managers keeping rental units comfortable, both get the same process: a real look at the equipment, a clear explanation of what is found, and a call to confirm the cost before anything is scheduled.
Call (781) 742-9359 any day from 6:00 AM to 10:00 PM.
A lot of the heating and cooling work in a town this size comes out of houses that were built decades before modern HVAC equipment was the default. Boilers that have run for years without a service visit, oil furnaces that are approaching the end of their useful life, and ductwork that was added as an afterthought rather than designed into the original structure are all common. The equipment often still works, but it works harder than it should, and the signs of strain are easy to miss until something stops entirely.
Hot-water boilers and baseboard radiation are the backbone of heating in many Medway homes. When a zone stops heating or the system loses pressure, the cause is usually a stuck zone valve, a circulator pump that has lost output, or an expansion tank that needs attention. A boiler service call covers pressure, zone-by-zone output, and the controls that sequence the zones. When a boiler is past the point where repair makes sense, replacement planning includes a look at the existing piping and radiation to make sure the new unit is sized correctly for the load.
The Northeast holds the large majority of the country's oil-heated homes, and Medway reflects that. When an oil furnace or boiler reaches the end of its service life, many homeowners use that moment to convert to gas or to a cold-climate heat pump. On the equipment side, a conversion involves removing the old oil appliance, installing the replacement unit matched to the home's existing layout, and commissioning the new system. Heat-pump conversions have become more common as the technology has improved for New England winters, and the call to discuss one starts the same way every other call does: scope the job, confirm the price, schedule the work.
Finished basements, sunrooms, and additions built onto older homes often end up outside the reach of the existing duct system. A ductless mini-split handles that without requiring any new ductwork. The outdoor compressor connects to a wall-mounted indoor unit through a small penetration in the exterior wall, and the result is a fully independent heating and cooling zone. A single-zone system can usually be completed in a day, and it does not depend on whatever the rest of the house is running.
We are available every day from 6:00 AM to 10:00 PM, including weekends, and emergency no-heat and no-cool calls are taken seriously. When a furnace stops working on a cold morning or an AC goes down during a stretch of humid weather, the call gets worked through on the phone so the scope is clear before anyone is dispatched. You know what the visit covers and what it costs before it is confirmed.
For properties with tenants or businesses that have to stay open, scheduling is worked out on the call. Access requirements, timing, and any coordination needed around occupants are all part of the conversation before the visit is booked. We do not show up and figure it out from there. The job is scoped first, and the visit is planned around what the property actually needs.
Your comfort is the whole job, and it gets treated that way.
Heating and cooling equipment conditions the temperature, but it does not automatically handle what is in the air. Filtration and humidity control are separate layers, and in an older home with a boiler or a ductless system, they require their own approach.
Whole-home air filtration connects to the existing HVAC equipment and treats the air as it circulates through the system. That is a different result from a portable unit sitting in one room. For homes with forced-air systems, upgrading the filtration in the air handler is often the most direct improvement. For homes running on hydronic heat with no air handler, a standalone whole-home purifier is the practical option. Either way, the visit starts with a look at what the existing system can support.
Humid summers and older building envelopes can leave a home feeling uncomfortable even when the thermostat reads the right number. A whole-home dehumidifier installed in line with the HVAC system removes moisture from the air as it passes through, which makes the cooling load easier to manage and the space genuinely more comfortable. In winter, a whole-home humidifier prevents the dry-air problems that come with forced-air heating. Both are worth discussing on the call if humidity is part of the complaint.
From aging systems to brand-new installs, the specific fault or situation determines what the visit covers and what the repair involves. These are the jobs that come up most often.
A cracked heat exchanger is one of the more serious furnace faults because it allows combustion gases to mix with the air the system distributes through the home. The symptom is often subtle: a furnace that trips a safety lockout after a few minutes, or a slight odor that is hard to place. A heat exchanger inspection looks at the exchanger directly, checks the flue, and confirms whether the system is safe to continue running. If the exchanger is cracked, the honest answer is replacement of the unit, not a patch.
A furnace that will not start, starts and then shuts off, or runs but produces no heat is usually pointing to one of a handful of components: the ignition system, the pressure switches, the flame sensor, or the blower. Each of those has a different fix, which is why the diagnostic comes before the quote. Running through the controls and the sequence of operation on the call helps narrow the likely cause before the visit even starts.
A system that starts, runs for a minute or two, and then shuts off before the space reaches temperature is short-cycling, and it puts unnecessary wear on the compressor and the heat exchanger. The cause is usually an oversized unit that was never matched correctly to the space, a refrigerant issue, a dirty evaporator coil restricting airflow, or a controls problem. Identifying which one requires a full diagnostic, because treating the wrong cause leaves the underlying problem in place.
An air conditioner or heat pump that is not cooling or heating to its rated output, or one that is icing up at the indoor coil, is often running low on refrigerant. Refrigerant does not deplete on its own. A low charge means there is a leak somewhere in the system, and adding refrigerant without finding and repairing the leak is a temporary fix. The diagnostic covers system pressures, coil condition, and a leak check before any refrigerant is added.
Whole-home humidifiers and dehumidifiers are installed in line with the HVAC system and work automatically as the system runs. A humidifier mounts at the air handler and adds moisture to the air during heating cycles. A dehumidifier removes moisture during cooling season or any time the indoor humidity is above a comfortable level. Both are sized to the home and calibrated to the existing controls, so they work with the thermostat rather than requiring a separate adjustment.
Knowing what a repair or replacement will cost before anyone starts is how the call is supposed to go. When you call, the conversation covers what the system is doing, what the service call involves, and what the diagnostic covers. You get the rate on the phone before anything is confirmed.
What moves a quote is what the fault actually turns out to be, what has to be accessed to reach it, and whether repair or replacement is the better answer given the age and condition of the equipment. A diagnostic that uncovers a cracked heat exchanger points toward a different conversation than one that finds a failed capacitor. We lay out both options with clear numbers when the situation calls for it, so the decision is based on the actual figures.
Ask what it covers and you get a straight answer. To see how it all fits together, read our heating and cooling services page.

We serve Medway and the surrounding communities throughout Norfolk County. Nearby towns we cover regularly include Holliston, Millis, Milford, and Bellingham. If you are in a community not on that list, call and ask about your address. Coverage questions are easy to answer on the phone, and we confirm what applies at your location before anything is scheduled.
If a repair requires a part that is not immediately available, we let you know on the diagnostic visit and give you a realistic sense of how long sourcing it is likely to take. Some parts are available quickly, others take longer depending on the equipment age and the manufacturer. We do not leave you without information while you wait.
Yes, in most cases. A replacement is typically completed in a single day, and while the system is offline during that window, the disruption to the tenant is manageable with some coordination. We talk through the timing and the access requirements with the property manager when the job is scheduled so the tenant is not caught off guard.
Often, yes. If the existing ductwork is in good condition and sized correctly for the new equipment, reusing it is the practical choice. We inspect the duct system as part of any replacement job and let you know whether the existing ducts are suitable or whether they need work. Forcing new equipment to work through undersized or deteriorated ducts affects performance and efficiency.
Yes. A home without ductwork is a natural fit for a ductless heat pump system, which connects an outdoor unit to one or more wall-mounted indoor units through a small wall penetration rather than through ductwork. The scope of that kind of conversion depends on the number of zones the home needs and the layout of the existing heating equipment being removed. Call and describe the current setup and we will walk through what the job involves and what it costs before anything is scheduled.
A single room that does not match the rest of the house is most often a duct or airflow problem rather than a failure of the main equipment. A damper that is stuck, a supply run that was never sized correctly for the room, or ductwork that has come loose in the attic or crawl space are the common causes. In older homes where ductwork was added after original construction, the distribution system sometimes was not designed with that room in mind. A diagnostic visit covers both the equipment and the duct system, because the right answer depends on where the air is actually going.
Medway has a significant share of older homes built around hot-water boilers, baseboard radiation, and oil-fired equipment. We work on all of it, including steam boilers, forced-air furnaces, heat pumps, and ductless mini-splits. If you are not sure what type of system you have, describing what you see in the basement or utility room on the call is usually enough to identify it.
A system that runs without satisfying the thermostat is usually losing capacity somewhere. The most common causes are a refrigerant charge that is low, a coil that is too dirty to transfer heat efficiently, or ductwork that is losing conditioned air before it reaches the living space. An oversized space relative to the equipment is another possibility. The diagnostic sorts out which of those is actually happening.
Yes, we take calls from managing agents and coordinate the visit directly with whoever has access to the property. The person who calls does not have to be the owner, and we confirm the scope and the price with the person authorizing the work before anything is scheduled.
Intermittent faults that appear only after the system has been running are often related to temperature or load. We run the system through a full cycle during the diagnostic and, where possible, replicate the conditions under which the fault appears. If the fault does not show during the visit, we note what the system is doing and use that to guide the next step.
Whatever the heating or cooling equipment is doing, the right first step is a call. We are available every day from 6:00 AM to 10:00 PM.
Call (781) 742-9359, describe what the system is doing, and get the scope and the price on the phone before any visit is confirmed.
Whether it is a boiler that has lost pressure, a mini-split that stopped heating, or a furnace that is short-cycling in the middle of winter, we will come out and look at it.
