HVAC Services in Islip, NY
Residential heating and air conditioning for homeowners in Islip — AC repair, furnaces and boilers, oil burners, heat pumps, ductless mini-splits, and the ductwork that ties it together.
Islip is a South Shore hamlet with a housing stock of older colonials, ranches, and capes, many dating to the early and mid-twentieth century. A fair number of these homes were built with oil heat and hot water baseboard, and a good share still run on oil today. The community sits close enough to the Great South Bay that salt air is a factor for outdoor condensing units on the blocks nearest the water.
Hartworx HVAC is a residential-only heating and cooling company based in Ronkonkoma, and Islip 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 Islip 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 Islip
Homes in Islip 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 Islip
Outdoor condensers in Islip that are within reach of the bay corrode faster than inland units — fin stock goes chalky, contactors pit, and a coil that looks intact can be rejecting heat badly. On the heating side, older oil-fired boilers in basements here are common and still serviceable, because cast iron is long-lived and the controls bolted to it are replaceable parts.
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 Islip, the equipment is looked at first and the diagnosis comes from what is actually there.
Islip HVAC questions, answered
Real questions from the kind of call that comes in from Islip. If yours is not here, call and describe what the system is doing.
My Islip home is near the bay and my outdoor AC unit corrodes fast. Is there anything to do about that?
There is. Salt air corrodes fin stock and contactors, and a coil that looks intact from outside can be shedding fin material and rejecting heat badly. Mounting position, clearance, drainage, and rinsing the coil with fresh water matter more here than they do inland. The condition of the coil is checked on a service visit, not assumed.
Does Hartworx service oil burners in Islip?
Yes. We service and repair oil burners in Islip and across Suffolk County. We service oil — we don't convert it, and we don't do oil-to-gas conversions or swap heat exchangers. If the burner is down, the job is to get it running.
My Islip house has hot water baseboard and no ducts. Can I add air conditioning?
Yes. A house on baseboard heat with no ductwork has real options for cooling. Ductless mini-splits can be added to individual rooms without touching the boiler, or a ducted system can be retrofitted if the house allows it. The choice comes from looking at the actual house.
There's water under my attic air handler. Should I shut the system off?
Shut it off. Water under an attic air handler usually means the condensate drain clogged and the secondary pan or float switch is missing or failed. The float switch that shuts the system down instead of letting water find the drywall is the detail that gets skipped on a lot of retrofits.
