Long Island's 24/7 Emergency HVAC, Heating, Cooling & Water Heater Service

An HVAC emergency is the kind of problem that does not wait for normal business hours. The boiler dies on the coldest night of January. The water heater bursts at 2 AM. The central AC quits during a July heat dome. The carbon monoxide alarm goes off. The oil tank starts seeping. When any of those things happens, you need a real local company that answers the phone, dispatches a real local tech, and shows up with the parts to fix it tonight.

That's what we do. All Island Comfort has answered Long Island emergency calls since 2004 from our base in Wading River. We cover all of Suffolk County and Nassau County. The phone rings to a real person every time, around the clock, including holidays and through every storm we've ever had. There is no voicemail, no offshore call center, no "we'll call you back Monday." Whatever your emergency is, we're already on it.

What Counts as an HVAC Emergency on Long Island?

If you're not sure whether your situation qualifies as an emergency, the simple rule is: if it's affecting your safety, your home's structural condition, or your basic ability to live in the house, it's an emergency. Below are the situations we treat as emergencies and dispatch immediately:

  • No heat in winter when outdoor temps are below 40°F
  • No hot water in a household with kids, elderly, or medical needs
  • No cooling during a heat advisory or heat wave
  • Suspected gas leak (call 911 + utility first, then us)
  • Carbon monoxide alarm activated in the home
  • Oil tank leak or strong oil smell in the basement or yard
  • Water heater tank rupture or active flooding
  • Burst or frozen pipes with active water damage risk
  • Smoke or burning smell from any heating or cooling equipment
  • Flooded boiler room or basement HVAC equipment
  • Sump pump failure with rising water
  • Equipment lockout you cannot reset after one or two attempts

Our 4-Step Rapid Response Process

  1. 1
    Triage on the call. A real Long Island dispatcher answers and walks through what's happening. We rule out anything you can fix in 60 seconds (tripped breaker, thermostat batteries, reset button), and if it's a real emergency we dispatch immediately.
  2. 2
    Local tech to your door. Typical response time is 1 to 3 hours across Suffolk and Nassau, faster for the North Shore corridor between Wading River and Port Jefferson because that's our home base. Your tech texts when they're 15 minutes out.
  3. 3
    Diagnose and quote before the wrench moves. Flat diagnostic fee, written quote on the spot, your approval before any repair starts. No surprise charges, no upselling.
  4. 4
    Fix it tonight when we can. About 85% of our emergency calls are completed on the first visit because the trucks are heavily stocked. For uncommon parts we identify them on visit one, source them next-day, and return without a second diagnostic charge.

What to Do While You Wait for Us

If You Smell Gas

Leave the house immediately. Do not flip switches, light matches, or use the phone inside. Once outside, call 911, then National Grid 24-hour gas leak line at 1-800-490-0045, then call us. We'll coordinate the safe restart of your heating system after the utility clears the leak.

If You Have a Water Leak or Burst Pipe

Shut off the main water supply if you know where the valve is (usually in the basement near the front of the house, or at the curb shut-off). Turn off the water heater (gas valve to "off" or breaker off). Move valuables off the floor. Then call us.

If You Have No Heat

Close interior doors to trap warmth in occupied rooms. Open kitchen and bathroom cabinet doors so heat reaches the pipes. Run cold water at a slow drip overnight on faucets along exterior walls to prevent frozen pipes. Pull out blankets and stay together in one room. We'll be there.

If You Have No Cooling in Extreme Heat

Move to the lowest level of the house (basement is coolest). Close blinds, shades, and curtains on sun-facing windows. Stay hydrated, especially elderly family and pets. Avoid the oven and dryer. If anyone shows signs of heat exhaustion, call 911.

Don't Wait Until It Gets Worse

The longer an HVAC emergency goes untreated, the more it costs and the more damage it causes. Call now and we'll get to you tonight.

FAQs

Long Island Emergency Service FAQs

Are you really available 24/7 on Long Island?

Yes. All Island Comfort answers the phone 24 hours a day, 7 days a week, 365 days a year, including holidays. Nights, weekends, snowstorms, heat waves, Christmas Day. The same local Wading River number rings to a real person every time, never a voicemail jail or offshore call center.

What counts as an HVAC emergency?

Anything that puts your home, your safety, or your comfort at immediate risk: no heat in winter, no hot water, AC failure during a heat wave, suspected gas leak, oil tank leak, water heater leak, smoke or burning smell from any equipment, carbon monoxide alarm, frozen pipes, or any equipment lockout you cannot reset. If you are not sure whether it qualifies, call us anyway and we will help you triage over the phone.

How fast can a technician reach my Long Island home?

Typical response times across Suffolk and Nassau counties run 1 to 3 hours from the call, depending on time of day, traffic, and current call volume. We dispatch from Wading River and have technicians staged across the East End and the North Shore for fast coverage. Existing customers and active service-plan members get first priority.

Do you charge extra for nights, weekends, or holidays?

After-hours dispatch carries a service-call premium that we disclose on the phone before we send a tech, never as a surprise on the invoice. We do not nickel-and-dime within the visit: the diagnostic fee is flat, the parts are quoted up front, and the labor is per-job not per-hour for most repairs. Service-plan members pay reduced after-hours rates.

What should I do while I wait for the technician?

If you smell gas, leave the house immediately and call 911 and PSEG / National Grid before calling us. For a water leak, shut off the water supply at the main if you can locate the valve. For no-heat, close interior doors to trap warmth in occupied rooms, run cold tap drips overnight to prevent frozen pipes, and unplug sensitive electronics. For no-cooling in extreme heat, move to the lowest level of the house and close blinds on sun-facing windows. The dispatcher will walk you through specifics for your situation when you call.

Do you carry parts on the truck or do you have to order them?

Our trucks are stocked with the most common emergency repair parts: igniters, flame sensors, blower motors, capacitors, contactors, oil burner nozzles and electrodes, circulator pumps, zone valves, common refrigerant types, water heater elements and thermocouples, and basic plumbing fittings. About 85% of our emergency calls are completed on the first visit. For uncommon parts we identify the part on visit one, source it next-day, and return without a second diagnostic charge.
