Heating Services across Nassau & Western Suffolk
Long Island HVAC Repair handles every kind of residential heating service: 24/7 emergency repair, annual tune-ups, and replacement for gas and oil furnaces, steam and hot-water boilers, and heat pumps. Techs are dispatched across Nassau and Western Suffolk, carry the common failure parts, and quote flat rates in writing before any work starts.
Looking for heating services near you? Long Island's housing stock is unusual — 1950s Levittown Capes with original steam boilers sit two blocks from 1990s colonials on gas furnaces and new builds on inverter heat pumps. Most companies specialize in one of those. We service all three, which means one phone number for a no-heat night, a fall tune-up, or a replacement quote.
Common signs you need heating repair
Catching these early prevents emergency calls and bigger repair bills down the road.
Failed ignitor, dirty flame sensor, tripped low-water cutoff on a boiler, or a dead thermostat. All four are diagnosed within about 15 minutes of arrival.
On forced air it's usually duct leakage or a closed damper. On baseboard it's usually air trapped in the loop or a failed zone valve.
Undersized or badly zoned equipment, a stuck fan-limit switch, or heavy envelope losses in an older un-insulated Cape.
Delayed ignition on a furnace or trapped condensate in steam pipes. Both need attention before they become expensive.
A neglected system loses efficiency every winter. A 15-year-old 80% furnace effectively wastes a fifth of what you pay for.
Leave the house, call 911, then call us. Cracked heat exchangers and blocked flues are the usual culprits.
Repair or replace?
The system is under 12 years old, the repair is under about $1,200, and the heat exchanger or boiler block is sound.
The unit is 15+ years old, the repair quote is over $1,500, or you're facing a second major failure in the same season.
You're on oil or electric baseboard. A heat pump or gas conversion usually pays back fastest on those two, and we'll run the numbers with your actual usage.
What a heating tune-up covers
Every visit follows the same documented checklist — so nothing gets skipped and you get a written report at the end.

Heating Repair questions, answered
Emergency repair, annual maintenance, and full replacement for gas and oil furnaces, steam and hot-water boilers, heat pumps, and dual-fuel systems. We also handle zoning, thermostats, and venting work.
We cover all of Nassau County and Western Suffolk, including Levittown, East Meadow, Bethpage, Wantagh, Massapequa, Hicksville, Plainview, Syosset, Garden City, Farmingdale, Jericho, and Oyster Bay.
Yes. A live dispatcher answers around the clock through the winter, and for a complete no-heat we typically arrive within 90 minutes.
Yes — oil furnaces and oil-fired boilers are common in older Long Island homes and we service, tune, and replace them, including nozzle, filter, and pump work.
$149–$229 for a single system. Our annual plan bundles the heating and cooling tune-up together for $249–$349 a year and waives after-hours fees.
Once a year, ideally in the fall before the first cold snap. Oil equipment genuinely needs it annually; gas furnaces and boilers are more forgiving but lose efficiency and warranty coverage without it.
Repair if it's under 12 years old and the fix is under about $1,200. Replace if it's 15+ years old, the repair is over $1,500, or the heat exchanger is cracked.
Yes. Cold-climate inverter heat pumps hold rated capacity down to around 5°F, well below a typical Nassau County design temperature. Many homeowners keep the existing furnace as backup in a dual-fuel setup.
No. If another company has quoted you a new furnace or boiler, we'll inspect the system and give you an independent written assessment at no cost.
