Doing HVAC work right matters, and we'll help you get it right, whether you're dealing with a furnace that stopped mid-January, an AC that can't keep up in July, or a system that's simply at the end of its useful life. Dedham HVAC Company handles residential and commercial heating and cooling across Dedham and Norfolk County, from routine tune-ups and emergency repairs to full system replacements. You get straight answers about your furnace, AC, and ductwork from the first call, not a sales pitch and not a runaround. We cover the full range: AC repair and service, furnace repair, heat pump service, ductless mini-split installation, boiler work, ductwork, thermostats, and indoor air quality. We'll handle the system so you don't have to.
Plain questions. Honest diagnosis. Clear options.
From aging systems to brand-new installs, the work we do covers every stage of a heating and cooling system's life. Whether a system needs a repair, a tune-up, or a full replacement, the visit starts with a real look at what's happening before anything is recommended.
When your central air stops cooling or starts short-cycling, the cause usually comes down to one of a handful of things: a refrigerant issue, a condenser or evaporator coil problem, a failing capacitor, or restricted airflow. A service call covers a full inspection of the system, refrigerant, airflow and controls all checked before a verdict, so you know exactly what's wrong before any repair is approved. If the system is old enough that repair costs approach replacement costs, that comparison gets laid out clearly so you can make an informed decision.
Furnaces fail at predictable points: the heat exchanger, the ignition system, the blower motor, and the pressure switches are the most common. A furnace inspection covers all of those, along with a check of the flue, the filter, and the controls. Sometimes the fix is a straightforward part swap. Sometimes the repair cost and the remaining service life of the unit point toward replacement instead. Either way, the diagnosis comes first and the recommendation follows from it.
A heat pump runs year-round in Massachusetts, handling both cooling in summer and heating through the shoulder seasons and mild winter days. That dual-season workload means the system needs attention twice a year, not just once. A tune-up covers refrigerant levels, coil condition, defrost controls, and airflow. If a heat pump is struggling to keep up or has stopped working entirely, the service call follows the same diagnostic process: find the cause, explain it, and present the options.
A thermostat that's reading the wrong temperature or failing to communicate with the air handler can make a perfectly functional system behave erratically. Thermostat installation, whether a basic programmable replacement or a full smart-thermostat setup with zoning controls, is a straightforward job that often has a noticeable impact on comfort and energy use. If you're running multiple zones or managing a multi-unit property, smart controls give you real visibility into what each zone is doing.
Leaking ductwork is one of the more common reasons a system runs longer than it should without actually conditioning the space. Duct sealing addresses gaps and disconnected sections that let conditioned air escape before it reaches the rooms that need it. On the air quality side, whole-home filtration and air purifier installation connect directly to the HVAC system and treat the air as it circulates, rather than relying on portable units in individual rooms. If airflow problems or uneven temperatures are the complaint, ductwork is usually part of the investigation.
We'll explain the diagnosis before any work is authorized.
Whether it's a one-time repair or a full system replacement, some jobs come up far more often in this part of Massachusetts than anywhere else in the country. Dedham's housing stock includes a significant share of older homes built around boilers, steam radiators, and oil heat. The Northeast accounts for the vast majority of oil-heated homes in the United States, and that shapes the work here. Humid summers and many homes without existing ductwork add ductless mini-splits to the regular call list as well.
Boilers are the backbone of heating in a large portion of Dedham's older homes, and they require a different kind of service than a forced-air furnace. A boiler service call covers the heat exchanger, the circulator pump, the expansion tank, the pressure relief valve, and the zone controls. Steam systems get their own set of checks: water level, steam traps, and venting. When a boiler reaches the end of its service life, replacement planning includes a look at the existing piping and radiation to make sure the new unit is sized correctly for the load.
Many homes in the area still run on oil, and the decision to convert is one of the more significant HVAC jobs a homeowner can take on. On the equipment side, a conversion involves removing the existing oil appliance, installing the new furnace, boiler, or heat pump, and connecting the controls. The result is typically lower fuel costs and a system that's easier to maintain. Heat-pump conversions in particular have become more common as cold-climate heat pump technology has improved, and careful HVAC work that respects your home is how that kind of project goes well.
Homes without existing ductwork, additions, sunrooms, and finished basements all run into the same problem: there's no practical way to extend a ducted system to condition the space. A ductless mini-split handles that by connecting an outdoor compressor to one or more wall-mounted indoor units through a small penetration in the wall, no ductwork required. Installation involves mounting the indoor and outdoor units, running the refrigerant line set, and connecting the controls. A single-zone system can be up and running in a day.
Homeowners in Dedham call for the full range: a furnace that stopped working on a cold morning, an AC that needs a tune-up before summer, a heat pump that's making a noise it didn't used to make, or a system that's old enough to replace. Single-family homes, older colonials with boilers, and newer construction with central air all get the same process: a real look at the system, a clear explanation of what's found, and a price before anything is scheduled.
Property managers and commercial clients have different demands. A multi-unit building with a failed rooftop unit or a commercial space with uneven temperatures needs someone who can scope the job accurately and get the work done without repeated callbacks. We handle commercial HVAC repair, maintenance, and replacement for properties across Norfolk County, and the call works the same way it does for a homeowner: scope the job, confirm the price, schedule the work.
Built for homeowners. Ready for property managers. Ready for your system.
When the heat or the AC quits, the situation doesn't wait for a convenient time. A furnace that goes out overnight in February or an AC that stops working during a humid Massachusetts heat stretch are the calls that need to move to the front of the line. Emergency no-heat and no-cool calls are taken seriously here. We're available every day from 6:00 AM to 10:00 PM, and when you call about an emergency, the scope of the problem gets worked out on the phone so you know what to expect before anyone is dispatched. The price is confirmed before the visit is scheduled, not after the work is done.
Here's what most people get wrong about their HVAC system: they wait until something breaks completely before calling, and then they're making a decision under pressure without a clear picture of what the repair or replacement actually costs. Calling before a system fails completely, or at the first sign of a problem, gives you more options and more time to make a good decision. When you call, the conversation covers what's happening with the system, what the service call involves, and what the diagnostic fee covers. You get the price on the phone, before anything is scheduled.
We pick up the phone and take care of it. There's no automated menu and no callback queue. A real person who knows the trade answers, scopes the job with you, and confirms what the visit covers. If you have questions about repair versus replacement, about what a tune-up involves, or about what a conversion project looks like on the equipment side, those get answered on the call.
A seasonal tune-up is the most straightforward way to avoid the kind of breakdown that happens at the worst possible time. A spring AC tune-up, scheduled before the cooling season starts, covers refrigerant levels, coil condition, airflow, capacitors, and controls. A fall furnace tune-up, before the first cold snap, covers the heat exchanger, ignition system, blower, filter, and flue. For heat pumps, both seasonal checks apply.
Homeowners who schedule regular maintenance tend to catch small problems before they become expensive ones. Property managers with multiple units benefit from a consistent inspection schedule that keeps systems running and reduces emergency calls. Annual HVAC service is available for both residential and commercial properties across Dedham and the surrounding area.
We handle heating and cooling work across Dedham and the broader Norfolk County area, including nearby communities throughout the region. If you're in Westwood, Norwood, Canton, Milton, Needham, West Roxbury, Hyde Park, or Readville, the same service applies. Call to confirm coverage at your address and to get a quote for the work.
If your heating system has stopped working, call us at (781) 742-9359 and we will work through what is happening on the phone before anyone is dispatched.
We are available every day from 6:00 AM to 10:00 PM, including weekends, so a no-heat call in Norfolk County does not have to wait. In the meantime, keep interior doors closed to hold whatever warmth remains in the rooms you are using, and if the system has a reset button, you can try it once, but do not keep cycling it if it trips again.
Yes, we handle commercial HVAC repair, maintenance, and replacement for businesses and multi-unit properties across Dedham and the surrounding Norfolk County area. Commercial calls come in with different scheduling and access requirements than residential ones, and we work through those details on the phone before anything is confirmed. The process is the same as a residential call: you get a scope and a price before the visit is scheduled.
We cover Dedham as our home base and take calls regularly from Westwood, Norwood, Canton, Needham, Milton, Walpole, Hyde Park, and Readville. If you are in a community not on that list, call and ask about your address. We serve the broader Norfolk County area and parts of the greater Boston metro, and coverage questions are easy to answer on the call.
When you call, we go through the scope of the job on the phone and give you a rate before anything is scheduled. Pricing depends on what the job actually is: a diagnostic service call, a refrigerant recharge, a blower motor replacement, and a full system replacement all carry different costs. You are told what the visit covers and what it costs before any work is authorized, so there is no ambiguity about what you are agreeing to.
Yes, we are available every day from 6:00 AM to 10:00 PM, including Saturdays and Sundays. Weekend calls are handled the same way as weekday calls: a scope and a price confirmed on the phone before the visit is scheduled.
If you have a heating or cooling issue that comes up over the weekend, call (781) 742-9359 and we will take it from there.
The decision usually comes down to two things: the cost of the repair relative to the age and remaining service life of the equipment. A repair that costs a significant fraction of a replacement, on a system that is already old, often points toward replacement. When the diagnostic uncovers that situation, we lay out both options with clear numbers so you can make the call based on the actual figures, not a guess.
A system that is failing repeatedly is usually telling you something about its overall condition. When a second or third repair comes up in a short window, we will say so directly and walk through what replacement would involve. Continuing to repair a system that is at the end of its service life costs more over time than a planned replacement, and that comparison gets made honestly on the call.
When you call, the conversation covers what the system is doing, what the service call involves, and what the diagnostic fee covers. You get the scope and the price on the phone before anything is confirmed. Once the visit is scheduled, the technician who comes out will run the diagnostic, explain the findings, and confirm any repair cost before work is authorized.
Yes, and older homes in Dedham make up a significant share of the calls we take. Homes built around boilers, steam radiators, and oil heat, or homes that were retrofitted with central air after original construction, often have equipment that is aging or systems that were never quite sized right for the space. We work on all of it, and we are straightforward about when repair is the right call and when the equipment has reached the end of its useful life.
It helps to clear a path to the furnace or air handler, the outdoor condenser or heat pump unit, and any return-air vents or registers that might be blocked by furniture. If the system has an air filter, note when it was last changed, since that information is useful during the diagnostic. Beyond that, just be available to describe what the system has been doing, because the symptom history helps narrow the diagnostic before any covers come off.
Lead times vary by season. During peak cooling season in summer and the early weeks of the heating season in fall, scheduling fills faster. For non-emergency work, calling a week or two ahead gives the most flexibility.
For emergency no-heat or no-cool situations, call (781) 742-9359 and we will work out what the schedule allows as quickly as possible.

Below is a plain look at the heating and cooling work we handle in Dedham and across Norfolk County. Each service comes with a short description of what it covers, who it fits best, and a practical note worth knowing before you call. Read through, find what matches your situation, and call us for a quote.
| Service | What the Service Includes | Common Needs | Things to Know |
|---|---|---|---|
| Oil-to-Gas & Heat-Pump Conversion | Old oil equipment removal, Gas furnace or heat pump installation, Compatibility with existing ductwork or hydronic layout, System commissioning | Homeowners whose oil boiler or furnace is at end of life and considering a fuel switch | Massachusetts has active energy programs around heat-pump electrification. The specifics change, so ask about current options when you call. |
| Ductwork Repair & Sealing | Duct inspection and leak detection, Sealing of gaps and disconnected sections, Airflow confirmation at registers, Attic and crawl-space duct assessment | Homes with uneven temperatures, weak register airflow, or high energy use relative to comfort | Older Dedham homes that had ductwork added after original construction often have runs that were never sized correctly for the layout. |
| Emergency HVAC Service | No-heat calls in winter, No-cool calls during heat stretches, System-down diagnosis, Safety lockout assessment | Anyone whose system has stopped working entirely or is unsafe to restart | We are available every day from 6:00 AM to 10:00 PM. Call and describe what the system is doing so we can scope the urgency before the visit. |
| Heat Pump Repair & Service | Refrigerant and defrost cycle check, Reversing valve diagnosis, Coil and airflow inspection, Controls and sensor test | Homes using a heat pump as the primary heating and cooling source | Heat pumps in Massachusetts shoulder-season temperatures are particularly sensitive to defrost control issues. We check that cycle as part of every service call. |
| Full System Installation & Replacement | Equipment sizing for the space, Indoor and outdoor unit installation, Refrigerant line set and air handler, System commissioning and test cycle | Homeowners or building operators replacing an aging or failed system | Correct sizing matters more than brand. A unit that is too large short-cycles and wears out faster than one matched properly to the space. |
| Seasonal Maintenance & Tune-Ups | Refrigerant level and coil cleaning, Heat exchanger and ignition inspection, Capacitor, contactor, and controls test, Full operating cycle confirmation | Homeowners who want to catch problems before they become emergency calls | Spring is the natural window for AC service. Fall is the window for heating. Scheduling before the busy season means faster appointment availability. |
| Ductless Mini-Split Installation | Wall-mounted air handler placement, Outdoor condenser installation, Refrigerant line set and control wiring, Single-zone or multi-zone commissioning | Older homes without ductwork, room additions, finished basements, or detached structures | A single-zone mini-split installation for one room can typically be completed in a day, with no ductwork required. |
| AC Repair & Service | Refrigerant pressure check, Coil and airflow inspection, Capacitor and contactor test, Controls diagnosis | Homeowners or property managers with an AC that is underperforming or not running | A system running but not cooling often points to a refrigerant issue or a frozen coil. Turning it off and calling early limits further damage. |
| Thermostat & Smart-Control Installation | Programmable and smart thermostat install, Calibration to existing equipment, Wiring and communication check, Zone control setup where applicable | Anyone whose thermostat is reading inaccurately or not communicating with the air handler | A thermostat that is slightly off in its temperature reading can cause the system to run longer than it should on every cycle across the whole season. |
| Boiler & Hydronic Heating Service | Zone valve and circulator pump check, Pressure and expansion tank assessment, Zone-by-zone output test, Controls and sequencing inspection | Norfolk County homes with hot-water baseboard or cast-iron radiator systems | A zone that is not heating is often a stuck zone valve rather than a boiler failure. We check each zone before drawing conclusions about the main unit. |
| Indoor Air Quality & Air Filtration | Whole-home air filtration installation, Air purification system integration, Humidity control assessment, Compatibility check with existing HVAC equipment | Households dealing with dust, allergens, or humidity problems that the standard filter is not addressing | Filtration upgrades work with the existing HVAC equipment and do not require a system replacement to be effective. |
| Heating & Furnace Repair | Ignition and burner check, Heat exchanger inspection, Flame sensor and pressure switch test, Controls and thermostat wiring | Anyone with a furnace that is short-cycling, failing to start, or producing less heat than usual | A furnace that trips its safety lockout repeatedly is telling you something specific. We check the cause before resetting anything. |
