Emergency Boiler Service, Seven Days a Week
A boiler that will not fire in January is an
emergency service call, and it should not have to wait for a weekday.

Call 516-409-8555 at any hour. We are available 7 AM to 7 PM, seven days a week, with no overtime charges. If you call after 7 PM, our automated system will take your details, and we will book your service for the first available opening the next morning.
Steam Boilers Are Their Own Animal, and We Speak Steam
Long Island is full of one-pipe and two-pipe steam systems, and older Garden City homes in particular still run on them. Steam behaves nothing like a hot water system, so it fails in ways a technician has to recognize on sight.
Call us if your steam system is doing any of this:
- Radiators and pipes banging or knocking, especially at the start of a cycle
- Uneven heat, where some radiators run hot and others never warm up
- A low-water cutoff that keeps tripping and shutting the boiler down
- A sight glass that will not stay clear, or a water line that swings
- Steam venting from a radiator vent long after the room is warm
We repair steam boilers, and when one is past saving we replace it with a properly sized unit and correct the near-boiler piping so the new one runs the way it should.
Signs Your Boiler Needs Service or Replacement
Call us if you notice:
- No heat or reduced heating output
- Unusual banging or whistling noises
- Water leaks around the boiler
- Rising energy bills with no change in usage
- Your boiler is over 15 years old and struggling to keep up
We’ll give you honest recommendations and quality work—every time.
Repair It or Replace It? Here Is How We Answer That
Most homeowners asking this are somewhere past the fifteen-year mark and tired of guessing. We walk through five things with you before recommending either one.
- What the repair costs against how many heating seasons the boiler has left in it
- How much fuel the current unit burns compared with a modern high-efficiency boiler
- Whether parts for the unit are still available, or whether the next failure means waiting on a part in the cold
- How many no-heat calls the boiler has already had this season, because two or three is a pattern rather than bad luck
- Whether the system is holding pressure and running clean between visits
A boiler with one failed part and good bones gets repaired. A boiler that has cost you three service calls in one winter is spending your money whether you replace it or not. Either way, annual service is what carries a boiler to the far end of its life, which is why our
Gold Care Club membership includes two precision tune-ups a year, 15% off all repairs, and an extended warranty on installations.

Where your boiler lands inside that range comes down to the job in front of us:
- Fuel type, gas or oil
- A standard boiler versus a high-efficiency condensing unit
- Steam versus hot water, since the two are not interchangeable installs
- The size the house actually calls for, which we calculate rather than match to the old unit
- Venting and chimney work, including a chimney liner where a high-efficiency unit changes the venting
- Near-boiler piping, when the unit moves or the existing piping is undersized
The price we quote is the price you pay. If the timing is harder than the number,
financing is available through an outside lender.

- Technicians who are professionally trained and perform all work under our company's Master Plumbing and HVAC licenses are dispatched 7 AM to 7 PM, seven days a week, with standard rates applying and no overtime charges
- Outside of those hours (after 7 PM or before 7 AM), an automated answering system takes your details and books your call into the first opening the next morning

Boiler Questions Homeowners Ask Us
How much does a new boiler cost on Long Island?
At Gold Star Home Service we publish a furnace and boiler replacement range of $9,500 to $14,000 and up. For qualifying customers, financing options are available for as low as $107.39 a month, making it easier to manage your investment without paying the full cost upfront. Where a specific job falls in that range depends on fuel type, whether the system is steam or hot water, the size the house requires, venting or chimney work, and whether the near-boiler piping needs to be redone. The written quote is flat-rate and includes labor, parts, materials, code compliance, testing, and cleanup.
Should I repair or replace a 20-year-old boiler?
At twenty years, replacement is usually the better math, though not always. Weigh the repair cost against the heating seasons the unit has left, how much fuel it burns against a modern high-efficiency boiler, whether parts are still available, and how many no-heat calls it has had this season. A single failed part on an otherwise sound boiler is worth repairing; three service calls in one winter is not.
Why is my steam boiler banging and knocking?
Banging in a steam system usually means water is sitting where steam is trying to travel, from a radiator pitched the wrong way, a clogged or failed vent, a wet return, or near-boiler piping that lets water carry over into the mains. It is not something to live with, because the same condition that makes the noise is stressing the pipes and the boiler.
