Old Town Plumbing, Heating, and Maintenance has been the go-to HVAC contractor for Hyannis homeowners, landlords, and businesses since 2014. Twelve years of residential and commercial heating and cooling work across Cape Cod, from routine tune-ups to full system replacements, built on one job at a time and one satisfied customer at a time. Being locally owned, our name rides on every service call. We answer when you call. We arrive when we say. We leave it running right.
We started in Hyannis in 2014 with a straightforward idea: show up when you say you will, do the work right, and treat people the way you would want to be treated. That approach built a customer base that has grown almost entirely through word of mouth and repeat calls across Barnstable County.
We work with single-family homeowners, landlords managing rental properties, property managers overseeing commercial buildings, and small business owners who need their systems running reliably. The range of customers is wide, but the standard of work stays the same across all of them. We are a local HVAC company homeowners rely on, and that reputation is something we protect on every job.
Our technicians know the housing stock on the Cape. Older construction, tight spaces, systems that have been patched together over the years, and coastal conditions that put real wear on equipment. We track down the problem fast.
Cape Cod summers are humid. When your air conditioner stops cooling, starts blowing warm air, or shuts down entirely, the inside of your home becomes uncomfortable quickly. We handle central AC repair, refrigerant leak diagnosis, condenser and compressor service, and spring tune-ups that catch small issues before they turn into a breakdown in July.
Whether your system needs a repair, a maintenance visit, or a full replacement, experienced technicians who respect your home show up ready to assess it honestly and explain what they find.
Cold, damp winters on the Cape make a reliable heating system non-negotiable. We repair and service gas furnaces, handle no-heat calls, and perform fall tune-ups that keep systems running through the season. If your furnace is struggling or your heat pump is not delivering what it should, we diagnose it and get it back on track.
Heat pumps are an increasingly practical choice for Cape Cod homes, offering both heating and cooling from a single system. We install, repair, and service heat pumps, and we can walk you through whether a heat pump makes sense as a replacement when your current system reaches the end of its useful life.
Many older homes in the Hyannis area rely on boilers and hydronic heating. We service and repair boilers and radiant heat systems, keeping the space-heating side of those systems running the way they should through the winter months.
There comes a point where repair no longer makes sense. An aging system, rising energy bills, and repeated breakdowns are all signs that a full replacement may cost less over time than continuing to patch an old unit. We help homeowners and property managers think through that decision honestly, without pushing toward a sale that is not warranted.
For homes without existing ductwork, or for additions and finished spaces that need independent climate control, we install ductless mini-split systems. Mini-splits are a strong fit for older Cape Cod homes where running new ductwork would be disruptive or impractical.
Pick up the phone and we'll handle the system.
We service heating and cooling systems every day, and we're good at it, which means we also see what happens when the supporting systems around the equipment are not working properly.
Leaky ducts are one of the most common and least visible sources of comfort problems and wasted energy in older homes. Conditioned air escapes into unconditioned spaces, rooms never reach the right temperature, and the system works harder than it should. We repair and seal ductwork, and we install new duct systems when a full replacement is the right call.
A thermostat that is not reading correctly or communicating with your system can cause comfort problems that look like equipment failures. We replace faulty thermostats, install programmable and smart thermostats, and set up zoning systems for homes that need different temperature control in different areas.
Coastal humidity and older construction make indoor air quality a genuine concern for many Hyannis-area households. We install whole-home air filtration systems, air purifiers, air scrubbers, and HEPA filters that work with your existing HVAC equipment. For homes that deal with dry winter air, we install whole-home humidifiers that connect directly to the heating system.
One ring and we're rolling.
Comfort problems don't wait, and neither do we, which matters especially for businesses that cannot afford a system failure during their busiest days.
We work with offices, retail spaces, restaurants, rental properties, and hospitality businesses across Hyannis and the surrounding county. Commercial HVAC work includes rooftop unit repair and service, commercial AC repair, commercial heating and furnace repair, and seasonal maintenance programs that keep systems tuned before peak demand hits.
Cape Cod's seasonal tourism economy puts real pressure on cooling systems during the summer months. But year-round businesses need reliable heat through the fall and winter just as much. We show up on time and ready to work whether the job is a summer AC call during a busy week or a heating repair in January when the guests are gone and the year-round staff still needs a warm building.
Don't let a small problem turn into a no-heat night or a no-cool afternoon, and if a system goes down, do not wait to call.
A heating system that stops working in January or an AC that fails on a hot August afternoon is not a problem that can wait until next week. We offer same-day service options and after-hours response for HVAC emergencies, including no-heat and no-cool calls on evenings and weekends. When you call, you reach someone who can schedule a technician, not a voicemail box.
We check the furnace. We check the AC. We leave it running right.
We explain what the work involves and what it costs before we start. That means assessing the system, telling you what we find, quoting the work, and waiting for your approval before anything moves forward. No surprise charges at the end of a job.
We protect your floors and finishes while we work, and we treat pricing the same way. A locally owned business that depends on its reputation in Hyannis and across Barnstable County prices work fairly. We are not in the business of padding invoices or recommending work that is not needed.
A seasonal tune-up is often the most cost-effective step a homeowner or property manager can take. Catching a small issue in the fall or spring costs far less than an emergency repair after a breakdown. Call to request an estimate or schedule a maintenance visit, and we will give you a clear picture of what the work involves and what it costs.

We protect your floors and finishes while we work and leave the work area the way we found it. That means laying down floor protection when we are moving equipment, cleaning up materials and debris before we leave, and treating your property with the same care we would want for our own.
Work is performed by trained HVAC technicians who have real experience on the kinds of systems that run in Cape Cod homes, including boilers, heat pumps, and ductless mini-splits. They communicate clearly, explain what they find, and do not start work until you have approved the quote.
We do. We give you a scheduled appointment time and we hold to it. We show up on time and ready to work, with the tools and parts to handle the most common problems on the first visit. If something changes on our end, we call you.
Being locally owned means the people who answer the phone and show up at your door are part of the same community you live in. Our reputation in Hyannis and across Barnstable County is built one service call at a time, and we take that seriously. Every job we do reflects directly on us.
Yes. Our vehicles are stocked with the tools and common parts needed for the work we do every day. We arrive prepared to diagnose and, in most cases, complete the repair in a single visit.

| Cape Cod homeowners ready to move away from oil heat and looking for a more efficient or lower-cost heating solution | the Northeast has the largest concentration of oil-heated homes in the country; we handle the HVAC side of the conversion and make sure the new equipment is sized and installed correctly |
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.
