24-hour emergency heating repair across Nassau & Suffolk. Live answer at night, upfront pricing, frozen pipe prevention.
Most emergency heating repairs total $189–$350, including the flat $189 service call that covers diagnosis and the first hour of labor; parts are billed separately. Nights, weekends and holidays carry a surcharge, typically $50–$150, quoted on the phone before a technician is dispatched, so the price never changes at the door.
A furnace that quits at 11 p.m. in January is not a schedule-it-for-Tuesday problem. Our phone is answered by a person around the clock, and we dispatch through the night in both counties, so a no-heat call from Hempstead, Mineola or Deer Park gets an arrival window during the first conversation instead of a promise of a morning callback. Every major brand is familiar equipment for us and every fuel common on Long Island: Carrier, Trane, Lennox and Rheem furnaces, Weil-McLain, Burnham and Peerless boilers, and the Beckett and Riello oil burners that still carry much of Suffolk. If you are searching for who to call when the heat stops overnight, the honest answer is any contractor who picks up live and quotes the after-hours surcharge on the phone. We do both, every night of the season, and our 24-hour furnace repair guide explains exactly how an overnight visit unfolds.
Before calling, check the thermostat batteries, the emergency switch at the top of the basement stairs, and the circuit breaker. If those are fine, the system itself has failed and a technician needs to see it; no-heat calls get priority dispatch any hour.
A house in a January cold snap loses roughly a degree an hour. By morning that is a frozen-pipe risk, not an inconvenience, which is why overnight failures should be called in when they happen, not at breakfast.
A dusty smell on the first cold day of the season is burn-off and passes within hours. A persistent electrical or oily smell is not: shut the system down at the switch and have it inspected the same day.
Delayed ignition is igniting fuel that has pooled in the chamber. Each bang stresses the heat exchanger, and on oil equipment it can crack the chamber. Stop using the system and call.
Leave the house first. Call 911 or your utility from outside, and let them clear the building. We handle the repair that caused it after the all-clear, on an emergency basis.
The expensive part of a cold night is rarely the heating repair itself. Hydronic baseboard, the most common heat on the island, runs its piping along exterior walls, exactly where freezing starts, and during a single-digit cold snap an unheated house can push those loops below 32°F in hours. A burst loop turns a $300 fix into a flooded finished basement and an insurance claim, which is why we treat every winter no-heat call as urgent whether it originates at the furnace or the boiler.
Emergency pricing stays simple after dark: the $189 service call still includes the first hour of labor, the after-hours surcharge is stated up front, and the repair price is approved by you before a tool comes off the truck. The farthest East End addresses may carry a small trip charge, quoted when the visit is booked, never added afterward.
Not every winter breakdown demands a 2 a.m. visit, and we will tell you honestly which kind you have when you call. A house dropping through the 50s with a hard freeze outside, an actively leaking boiler, a carbon monoxide alarm, or vulnerable occupants justify immediate dispatch. A system limping along but holding 62°F on a mild night is often better served by the first morning slot at regular rates, and we say so on the phone rather than collect a surcharge you did not need to pay. That judgment costs nothing either way; the line is answered by a person at any hour, every day of the season, and the advice is free even when the visit can wait.
One more reason not to ignore a struggling system: incomplete combustion produces carbon monoxide, and the EPA’s carbon monoxide guidance is blunt about how dangerous an unvented fault can be. Working CO detectors and a prompt repair are the whole defense.

Yes, and we say so up front. An after-hours surcharge of $50–$150 applies outside normal hours and is quoted on the phone before anyone is dispatched. The service call itself stays a flat $189 and still includes the first hour of labor.
It depends on outdoor temperature, wind and insulation. In a deep freeze, baseboard loops on exterior walls can reach freezing within hours, well before the rooms themselves feel dangerous. If the outdoor temperature is in the teens or lower, treat any no-heat situation as urgent and run a trickle of water at the farthest faucet while you wait.
In winter, yes. A house with infants, elderly residents or anyone medically vulnerable should not wait overnight, and even an empty house is at risk once interior temperatures slide toward freezing. That is exactly the situation our overnight dispatch exists for.
No. A gas oven running with the door open is a carbon monoxide risk and was never designed to heat a room. Use a properly rated electric space heater in one closed-off room instead, and keep it clear of bedding and curtains.
We dispatch across both counties day and night. The farthest East End locations may carry a small trip charge, which we quote when the call is booked, never on arrival.
