HVAC Services in Smithtown, NY
Residential heating and air conditioning for homeowners in Smithtown — AC repair, furnaces and boilers, oil burners, heat pumps, ductless mini-splits, and the ductwork that ties it together.
Smithtown is the main community of the Town of Smithtown, on the North Shore of Long Island. The housing stock runs from older colonials and capes dating to the early twentieth century to mid-century ranches and later construction. Many of the older homes were built with hot water baseboard or steam heat, and the hilly North Shore terrain affects equipment access and duct routing. The age and variety of the housing means a service call starts with finding out what is actually in the basement.
Hartworx HVAC is a residential-only heating and cooling company based in Ronkonkoma, and Smithtown sits inside that service footprint. The owner, Travis Hart, has worked in the HVAC trade since 2017 and answers the phone himself — there is no dispatcher between you and the person who shows up at the door. When equipment in Smithtown fails, the call is to (631) 873-5844 and the job is to get it running again, not to sell you something you do not need.
Heating & air conditioning services in Smithtown
Homes in Smithtown run on a mix of forced-air furnaces, hot water and steam boilers, oil burners, central air, heat pumps, and ductless systems. The work below is what we do here — each links to the page that explains it in detail rather than repeating the same description on every town page.
What's different about Smithtown
Older boilers in Smithtown basements are common and often still serviceable — cast iron sections are heavy and long-lived, and the controls bolted to them are replaceable parts. The same street can have a steam system, a hot water boiler, and a forced-air furnace, which is why the call starts with what is actually there rather than what the homeowner assumes.
The point of naming it is that the fix is not the same everywhere. A condenser on a salt-air block, a flex duct run through a 120° attic, and a thirty-year-old cast iron boiler in a damp basement are three different jobs, and the wrong move on any of them is to treat it like the other two. On a service call in Smithtown, the equipment is looked at first and the diagnosis comes from what is actually there.
Smithtown HVAC questions, answered
Real questions from the kind of call that comes in from Smithtown. If yours is not here, call and describe what the system is doing.
My Smithtown home is older with a boiler. Do you service that?
Yes. Hartworx works on older heating systems — hot water boilers, steam, and oil burners — in homes across Smithtown. Cast iron boilers are heavy, simple, and long-lived, and the controls bolted to them are replaceable parts. A failure is usually a repair, not a funeral.
Do you service oil burners in Smithtown?
Yes. Hartworx services and repairs oil burners in Smithtown. We service oil — we don't convert it, and we don't do oil-to-gas conversions or swap heat exchangers. If your burner is down, the job is to get it running.
My Smithtown house has baseboard heat and no ducts. Can I add cooling?
Yes. Ductless mini-splits can be added to individual rooms without touching the boiler, or a retrofit ducted system can go in if the house allows it. The right choice comes from looking at the actual house.
My boiler is old but still works. Should I replace it?
Often, no. An old cast iron boiler that still fires, holds pressure, and heats the house is worth keeping. The controls bolted to it are replaceable parts. We will tell you plainly which situation you are in.
