Old Town Plumbing, Heating, and Maintenance has been the go-to heating and cooling contractor for Hyannis homeowners, landlords, property managers, and businesses since 2014. We handle repair, installation, replacement, and maintenance for all residential and commercial HVAC equipment across Hyannis and Barnstable County. Whether your heat stopped working on a January night or your AC gave out in July, we are ready to help. A local HVAC company homeowners rely on, we take every call seriously and treat every job like it matters.
We answer when you call. We arrive when we say. We leave it running right.
Same-day appointments are available, and we respond to after-hours emergencies. Call (774) 822-6289 for a quote or to schedule a service call.
We cover the full range of heating and cooling work, from a quick repair to a full system replacement. Here is what we handle every day:
No job is too routine and no problem is too complicated. We track down the problem fast.
Comfort problems don't wait, and neither do we. When the heat goes out in the middle of a cold Cape Cod winter or the AC fails on a humid August afternoon, you need someone who picks up the phone and gets there.
We dispatch qualified technicians ready to diagnose and repair on arrival. Whether you are a homeowner dealing with no heat, a property manager with a tenant calling at 10 p.m., or a business owner who cannot open without a working system, we show up on time and ready to work. You will hear an honest assessment of what is wrong, what it takes to fix it, and what the timeline looks like before any work begins.
Call (774) 822-6289 now for same-day or emergency HVAC service.
A furnace that stops working, blows cold air, or short-cycles is more than an inconvenience in a Massachusetts winter. We diagnose and repair all common furnace problems, including blower motor and airflow issues, faulty capacitors and igniters, and heat exchanger concerns. When a repair no longer makes sense, we handle full furnace replacement and new furnace installation as well.
Before any work begins, you get a clear estimate. No surprises on the invoice. Pick up the phone and we'll handle the system.
We service heating and cooling systems every day, and we're good at it. When your AC stops cooling, freezes up, or starts making noise, we get to the root of the problem. We handle refrigerant leak diagnosis, condenser and compressor issues, evaporator coil service, and full AC replacement when the equipment has run its course.
Cape Cod summers bring real humidity and stretches of heat that push older systems hard. A seasonal tune-up before the warm months arrive is one of the best ways to avoid a breakdown mid-summer. Experienced technicians who respect your home will walk through the system, catch small issues early, and leave it ready for the season.
Heat pumps do double duty, handling both heating and cooling from one system. That makes them a practical fit for Cape Cod's mixed climate, where you need reliable warmth in winter and comfortable cooling in summer. When a heat pump stops working, blows cold air in heat mode, or loses efficiency, we diagnose the problem at the source: refrigerant levels, reversing valve function, airflow, and controls.
We also install new heat pump systems and handle full replacements when equipment reaches the end of its useful life. One ring and we're rolling.
Barnstable County sits at the edge of the Atlantic, which means long heating seasons, coastal humidity, and some of the oldest housing stock in the country. Much of the Cape still runs on oil-fired boilers and steam or hot-water radiators. Fuel costs and the push toward cleaner energy have a growing number of homeowners moving away from oil. And many older Cape Cod homes were built without ductwork, making ductless systems the most practical path to modern comfort. These are the jobs we handle regularly, and we know this equipment well.
Many Hyannis-area homes heat with oil-fired boilers connected to steam or hot-water radiators. That equipment can run for decades with the right care, but it needs attention. We service, repair, and tune up boilers of all types, including zone valve and circulator pump service, pressure checks, and full diagnostic work. Keeping your boiler running efficiently through the heating season matters here, and we treat that work seriously.
The Northeast holds the largest concentration of oil-heated homes in the country, and many Cape Cod homeowners are ready to make the switch. Whether you are moving to natural gas or converting to a heat pump system, we handle the HVAC side of the job: equipment selection, system sizing, and installation of the new heating unit. We focus on getting the right equipment in place and making sure it performs.
Older Cape Cod cottages, room additions, and sunrooms often have no ductwork at all. A ductless mini-split system solves that problem cleanly. We install mini-splits that handle both heating and cooling, giving you year-round comfort and zone-by-zone control without tearing into walls for duct runs. We also service and repair existing mini-split systems across the area.
A properly calibrated thermostat makes every other part of your HVAC system work better. We install and replace programmable thermostats, Nest, Ecobee, and other smart-control models, and we troubleshoot thermostats that are not reading or responding correctly. The right control setup improves comfort and helps keep energy use in check.
Leaking or damaged ductwork drives up energy costs and leaves some rooms too hot or too cold. We locate the problem, seal the leaks, and repair or replace sections that are no longer doing their job. Sealed ducts mean the conditioned air you are paying for actually reaches the rooms it is supposed to reach.
Cape Cod's coastal humidity makes indoor air quality a real concern for many homeowners. We install whole-home air filtration systems, UV air purifiers, and whole-home humidifiers and dehumidifiers. Better filtration means cleaner air circulating through the system, which matters for anyone dealing with allergies, dust, or moisture issues inside the home.
The best way to avoid an emergency call is a maintenance visit before the season hits. We check the furnace. We check the AC. We leave it running right.
A maintenance visit covers the full system: filter check, coil cleaning, refrigerant level check, electrical connections on the equipment, thermostat calibration, and a complete run-through to catch anything that looks like a problem in progress. Fall is the right time to service your heating system. Spring is the right time for the AC. Both visits together give your equipment the best chance of running through the season without a breakdown.
Commercial properties benefit from the same approach. Planned maintenance keeps your building comfortable and your tenants or customers from noticing the system at all.
Property managers, restaurant and retail operators, and office building owners in the Hyannis area count on us for commercial AC repair, commercial heating repair, commercial HVAC installation, and ongoing maintenance. We work around your schedule, communicate clearly on scope and timeline, and we protect your floors and finishes while we work.
Commercial customers get the same straightforward pricing and scheduling as residential. No separate rate card, no runaround. You call, we come out, you get an honest estimate before the work starts.
Don't let a small problem turn into a no-heat night or a no-cool afternoon. Calling early almost always costs less than waiting until the system fails completely.
HVAC pricing depends on the equipment, the scope of the repair or installation, and what the diagnostic turns up. We do not quote flat rates that do not reflect the actual job. What we do is give you a clear estimate before any work begins, so you know what you are agreeing to.
Being locally owned, our name rides on every service call. We have no reason to oversell a job or recommend work that does not need doing. Straight answers and fair pricing are how we have kept customers coming back since 2014.
Hyannis is our home base, and we run service calls across Barnstable County and the wider Cape Cod area every day. Our team knows the roads, the neighborhoods, and the housing stock out here.
We regularly serve:
If you are nearby and need HVAC service, give us a call.
We have been doing this work in the Hyannis area since 2014. That is more than a decade of heating seasons, summer AC calls, boiler tune-ups, and mini-split installs across Cape Cod. We know the equipment that runs in these homes, and we know what it takes to keep it running.
Ready to get the comfort back? Our team is built around technicians who have put in real time on real systems. Work is performed by trained technicians who take the job seriously, communicate clearly, and leave the work area the way they found it.
We are a local HVAC company homeowners rely on, and we plan to keep it that way. Every call we take is a chance to earn a customer for the long run, and we treat it like one.
When you call, we schedule a time that works for you and send a qualified technician to your home or property. The technician inspects the system, diagnoses the problem, and explains what they found before any work begins. You get a clear quote, and we proceed only after you approve it. No surprises on the invoice when the job is done.
Yes. When you call (774) 822-6289, you reach someone local who knows the Hyannis area and can get you on the schedule. Being locally owned, our name rides on every service call, and that starts with how we answer the phone.
Warm air coming from the vents when the AC is running, weak airflow throughout the house, a system that keeps cycling on and off in short bursts, or unusual noises like banging or rattling are all reasons to call. Catching these early almost always costs less than waiting until the system stops working entirely. Call (774) 822-6289 and we can usually get someone out the same day.
We work with your schedule. When you call, let us know what times work best and we will find an appointment that fits. Same-day options are available for urgent situations, and we offer appointments across a wide range of hours so you are not forced to take time off work for a service call.
Most repairs and maintenance visits take one to three hours depending on the system and what the diagnostic turns up. A straightforward repair on a familiar system is usually faster. A more involved job, like a component replacement on a boiler or a full system diagnostic, may take longer. We give you a realistic time estimate once we have assessed the equipment.
The scope of the work is the main driver. A system that has not been maintained in several years may have multiple issues that need attention. Parts availability, system age, and access to the equipment can all affect the final cost. We explain all of that before the work starts so you know what you are agreeing to.
A repair makes sense when the equipment is in good overall shape and the cost is reasonable relative to the system's remaining life. 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.
The price covers the technician's time, the diagnostic work, and the repair or service performed. Parts are included in the quote we give you before work begins. We do not charge separately for the diagnosis after the fact or add fees that were not discussed upfront.
Repeated breakdowns on an aging system are a sign that the equipment has reached the end of its useful life. At that point, continuing to repair it often costs more than replacing it. We will tell you honestly when we think a replacement makes more financial sense, and we handle full system installation and replacement when you are ready to move forward.
We live here. We keep this area comfortable. We stand behind our work.

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.
