Old Town Plumbing, Heating, and Maintenance has been handling heating and cooling for homes, rental properties, and businesses across Cape Cod since 2014. We work on everything from a furnace that stopped firing on a cold January night to a ductless mini-split going into a century-old cottage that never had central air. Residential, commercial, single-family, multi-unit. We cover it all. Being locally owned, our name rides on every service call. Call (774) 822-6289 for a quote or to schedule service.
We answer when you call. We arrive when we say. We leave it running right.
We service heating and cooling systems every day, and we're good at it. Our work covers the full range: AC repair and service, furnace and heating repair, heat pump service and installation, ductless mini-split installation, boiler and hydronic heating, ductwork repair and sealing, thermostat and smart-control installation, indoor air quality, seasonal maintenance and tune-ups, and emergency HVAC calls.
We work with homeowners, renters, landlords, property managers, and small businesses across Barnstable County. Whether you need a quick repair, a full system replacement, or a seasonal tune-up before the weather turns, experienced technicians who respect your home are ready to handle the job. Pick up the phone and we'll handle the system.
A Cape Cod summer is humid, and a cooling system that underperforms or quits makes that humidity miserable fast. When we come out for an AC service call, we diagnose the problem from the start. That means checking refrigerant levels and inspecting for leaks, examining the condenser and compressor, checking the evaporator coil, and working through airflow and uneven-temperature issues that often get ignored until they get worse.
We show up on time and ready to work, with the tools and parts to handle the most common AC problems in a single visit. If your system is beyond repair or simply too old to run efficiently, we handle central air installation and full AC replacement as well. One ring and we're rolling.
Don't let a small problem turn into a no-heat night or a no-cool afternoon. Furnaces give warning signs before they fail, and catching a problem early saves real money. When we come out for a furnace call, we check the heat exchanger, inspect the burner and ignition system, test airflow through the air handler and blower, and run a full diagnostic before we recommend any repair.
For older systems that are failing or have simply run their course, we handle furnace installation and replacement. Seasonal maintenance and tune-ups are a natural fit here too. A furnace that gets a proper inspection each fall runs more reliably all winter. We track down the problem fast.
Heat pumps are a strong fit for the Cape Cod climate. Winters here are moderate compared to the rest of Massachusetts, and heat pumps perform well in that range. Humid summers are no problem either. A heat pump handles both heating and cooling from a single system, which makes it a practical upgrade for homeowners looking to move away from older oil or gas equipment.
When a heat pump is not performing, we check refrigerant charge, inspect the reversing valve and defrost cycle, test airflow, and run a full diagnostic. For installations and replacements, we size the equipment to the space and handle the full setup. Heat pump installation also ties naturally into the conversion work we do on older oil systems, which we cover in the regional services section below.
A few services come up more often in this area than anywhere else in the country. Older homes on Cape Cod were built with boilers and radiators, and a large share still run on oil. The shift away from oil heat is well underway, and ductless mini-splits are a practical answer for the many homes and cottages that were never built with ductwork. These three services are a core part of what we do in Barnstable County.
Cape Cod has some of the oldest housing stock in the country, and a significant share of it heats with a boiler. Steam and hot-water systems with radiators or baseboard heat are common throughout the area. When a boiler is not performing, the problem can be anywhere: pressure, zone valves, the circulator pump, thermostat controls, or the heat exchanger itself. We check all of it.
A boiler service call covers a full system inspection and diagnosis. We handle both repairs and full boiler replacement when a system is at the end of its life. If you have radiators that are not heating evenly, zones that are not responding, or a system that is making noise it should not be making, call us and we will figure out what is going on.
Many Cape Cod homeowners are moving off oil heat. Fuel costs, supply reliability, and the region's moderate winters all make heat pumps and gas heating equipment a sensible switch. We handle the HVAC side of that conversion: removing the old oil equipment, installing the new heat pump or gas heating system, connecting it to existing ductwork or hydronic distribution, and configuring the thermostat and controls.
We protect your floors and finishes while we work, and we leave the space clean when we are done. The gas-line and electrical work are handled by the appropriate trades. We focus on the heating and cooling equipment and make sure it is installed and operating correctly before we leave.
Older homes, cottages, additions, and finished spaces on Cape Cod often have no ductwork at all. A ductless mini-split solves that problem cleanly. We place the indoor air handler where it will cover the space effectively, run the refrigerant line set to the outdoor condenser, and set up the thermostat or remote controls.
Modern heat pump mini-splits provide both heating and cooling, which makes them a year-round solution, not just a summer fix. For seasonal-use properties and older homes that were never set up for central air, they are often the most practical path to real comfort. We track down the problem fast.
Leaky or damaged ductwork wastes the energy your heating and cooling system produces and creates the uneven temperatures that make some rooms comfortable and others miserable. When we find ductwork problems, we repair and seal the ducts to bring airflow back to where it should be. This kind of work often resolves comfort complaints that have gone unsolved for years.
Thermostat and smart-control installation is a straightforward upgrade that pays off quickly. A properly programmed smart thermostat keeps the system running efficiently without asking you to think about it. We handle the installation and make sure the controls are set up to match how you use the space.
Indoor air quality matters on the Cape, where coastal humidity, seasonal pollen, and older home construction combine to create real air quality challenges. We install air filtration systems and air purifiers that work with your existing HVAC equipment. For spaces where humidity is a persistent issue, we can discuss whole-house humidity control as part of a broader comfort solution.
Comfort problems don't wait, and neither do we. A no-heat call on a cold Cape Cod night or a no-cool call in the middle of August needs a same-day response. We handle emergency HVAC service for exactly these situations: system down, no heat, no cooling, equipment that stopped working without warning.
When you call, we get a technician out as quickly as possible. We diagnose the system, tell you what we found, and work toward same-day resolution wherever the repair allows for it. We answer when you call. We arrive when we say. We leave it running right. Call (774) 822-6289 now.
We work across the full range of property types in the area. For homeowners and renters, that means repairs, new installations, and seasonal tune-ups handled by a local HVAC company homeowners rely on. For landlords, property managers, and small businesses, it means scheduled maintenance, multi-unit service visits, and system replacement planning that keeps properties running without surprises.
Whether you are managing a single rental cottage in Yarmouth or a small commercial building in Hyannis, we bring the same level of care to the job. Call for a quote and we will talk through what your property needs.

Call (774) 822-6289 to request an estimate or schedule a service call.
If the heat is out, close off unused rooms to hold warmth in the occupied spaces. If the AC has failed, close blinds on sun-facing windows to slow heat gain. Do not try to reset or force the system repeatedly, as that can make some problems worse. Call (774) 822-6289 and we will give you any additional guidance specific to your situation while a technician is on the way.
We offer same-day service options and after-hours response for emergencies including no-heat and no-cool situations. Response time depends on current call volume, but we prioritize system-down calls and aim to get a technician to you as quickly as possible. Call (774) 822-6289 and we will give you a realistic arrival window right away.
The technician starts with a full system inspection: checking the thermostat and controls, inspecting the air handler and outdoor unit, testing airflow, and running the system through its operating cycle to observe how it behaves. From there, they narrow down the cause and explain what they found before recommending any repair. We track down the problem fast.
A burning smell when the heat first comes on in the fall is often dust burning off the heat exchanger and may clear on its own. A persistent burning smell can indicate an electrical issue within the equipment or an overheating motor, and that warrants a service call. A musty smell usually points to mold or mildew growth in the ductwork or on the evaporator coil. Both are worth having a technician look at.
Banging often points to a loose or broken component inside the air handler or blower assembly. Squealing usually indicates a worn belt or a bearing that needs attention. Rattling can mean loose panels, debris in the system, or a component that has come loose. None of these sounds should be ignored, as what starts as a minor mechanical issue can become a larger failure if left alone.
Older equipment loses efficiency as components wear, coils accumulate buildup, and the refrigerant charge drifts. A system that has not been maintained in several years is often working much harder than it needs to in order to reach the set temperature. A tune-up can recover some of that lost efficiency. If the system is old enough, a replacement with modern equipment may deliver better results than continued maintenance.
Leaky ducts allow conditioned air to escape into unconditioned spaces like attics, crawl spaces, and wall cavities before it reaches the rooms you are trying to heat or cool. Undersized ducts restrict airflow and force the system to work harder. Both problems drive up energy use and create uneven temperatures throughout the home. Sealing and repairing ductwork is one of the most cost-effective improvements a homeowner can make.
When a system is more than fifteen years old, has needed repeated repairs in a short period, or the cost of the current repair approaches a significant fraction of replacement cost, a full replacement often makes more financial sense. We give you an honest comparison when we assess the system, and we do not push a replacement if a repair is the right call.
We assess the existing system, confirm the right equipment size for the space, and provide a quote before any work begins. On installation day, we remove the old equipment, install the new unit, connect it to the existing distribution system, and test it fully before we leave. We walk you through the new controls and make sure you are comfortable with how the system operates.
The right answer depends on the age and condition of your current equipment, your energy costs, and what you want from the system going forward. A repair makes sense for equipment that is in good shape with a problem we can fix efficiently. A heat pump is worth considering when you are ready to move away from oil or when you want a system that handles both heating and cooling. We walk you through the options and give you a straight answer on what fits your situation.
Older homes on the Cape often have uneven temperatures between floors or rooms, drafts around windows and exterior walls, and heating systems that were sized for a different layout than what exists today. Ductwork that has never been sealed, outdated thermostats, and aging boilers or furnaces all contribute. We see these issues regularly and know how to address them.
Clear a path to the equipment the technician will be working on, whether that is the furnace, air handler, boiler, or outdoor unit. Move any storage that blocks access to the mechanical room, attic hatch, or crawl space entry. If there are registers or vents in rooms that are part of the complaint, make sure those areas are accessible. The technician will let you know if anything else needs to be moved once they see the layout.
For work that requires a permit under Massachusetts building code, we handle that process. We let you know upfront whether a permit applies to your job. Permitted work protects you as the homeowner and ensures the installation meets code requirements for the equipment.
Changing a filter, clearing debris from around an outdoor unit, or replacing a thermostat are tasks most homeowners can handle safely. Anything involving refrigerant, electrical connections within the equipment, the heat exchanger, gas connections to the unit, or internal components of the air handler should be handled by a qualified HVAC technician. Attempting those repairs without the right training and tools can make the problem worse and create safety risks.

How do I know whether to repair or replace my HVAC system?
A repair makes sense when the equipment is in good overall shape and the cost is reasonable relative to what the system has left in it. When a system is old, inefficient, and breaking down repeatedly, a full replacement often costs less over time. We give you an honest assessment of both options and let you decide. There is no pressure from our side to go one way or the other.
What are the signs that my furnace or boiler needs attention right away?
A system that stops producing heat, blows cold air, short-cycles, makes banging or rattling noises, or smells unusual when it runs is telling you something is wrong. Catching these early almost always costs less than waiting until the equipment fails completely. Call us and we can usually get someone out the same day.
How often should I schedule a maintenance tune-up?
Once a year for each season is the standard: a heating system check in the fall before the cold arrives, and an AC or cooling system check in the spring before summer. Both visits together give your equipment the best chance of running through the season without a breakdown. Properties with heavier use or older equipment may benefit from more frequent attention.
Upfront Quotes With No Surprise Fees
We give you a clear estimate before any work begins and explain exactly what it covers. What you approve before we start is what appears on the invoice when the job is done.
What does a seasonal tune-up actually cover?
We go through the full system: filter check, coil cleaning, refrigerant level verification, electrical connections on the equipment, thermostat calibration, and a complete run-through to catch anything that looks like a problem in progress. You get a clear picture of where the system stands and what, if anything, needs attention before the season starts.
Why is one room in my home hotter or colder than the rest?
Uneven temperatures are usually a sign of a ductwork problem, an airflow issue, or a system that is not sized correctly for the space. Leaking or disconnected ducts are a common cause. A mini-split system can also solve the problem in rooms that have never had good comfort, particularly in older Cape Cod homes where ductwork was never installed.
What can strange noises from my HVAC system mean?
Banging or clanging usually points to a loose or broken component inside the unit. Rattling can mean debris in the system or a loose panel. A high-pitched squeal often signals a blower motor or belt issue. None of these should be ignored. The longer a mechanical problem runs, the more damage it can cause to surrounding components.
Experienced With Older and Newer Systems
Cape Cod's housing stock runs the full range, from decades-old oil boilers to modern heat pump systems. We know this equipment and we know what it takes to keep it running correctly in this climate.
How does a ductless mini-split compare to a central system for an older Cape Cod home?
Many older homes on the Cape were built without ductwork, which makes a central forced-air system impractical without major renovation work. A ductless mini-split installs cleanly, handles both heating and cooling from one system, and gives you zone-by-zone control. For a cottage, a sunroom, or a room addition, it is usually the most practical and cost-effective path to year-round comfort.
What is involved in converting from oil heat to a heat pump or gas system?
We handle the HVAC side of the job: equipment selection, system sizing, removal of the old heating unit, and installation of the new system. The work involves making sure the new equipment is correctly sized for the home and that it performs as expected after installation. We focus on the heating and cooling unit itself and make sure everything is calibrated and running before we leave.
Same-Day and Emergency Availability
When the heat goes out or the AC fails, we dispatch qualified technicians ready to diagnose and repair on arrival. Same-day appointments and after-hours service are available for situations that cannot wait.
Do I need to be home for a service call or installation?
For a repair or diagnostic visit, someone should be present to give the technician access to the equipment and to hear the assessment before work begins. For a larger installation, we coordinate with you on timing and access. We work with your schedule and let you know what to expect so you are not left guessing.
How does pricing work, and will I know the cost before work starts?
You get a clear estimate before any work begins. Pricing depends on the equipment, the scope of the repair or installation, and what the diagnostic turns up. We do not add fees that were not discussed upfront. What we quote is what you agree to before we start, and that is what appears on the invoice when the job is done.
Is emergency or same-day service available for a system that has completely stopped working?
Yes. We dispatch qualified technicians for same-day and after-hours situations. Whether you are a homeowner with no heat on a January night, a property manager with a tenant calling late, or a business that cannot operate without a working system, we show up on time and ready to work. Call us and we will get someone out as quickly as possible.
Call (774) 822-6289 and we will walk you through your options, give you a straight answer on what the system needs, and get you on the schedule.
