How Is a
Boiler Installation & Replacement on Long Island
A properly installed boiler can keep your home comfortable for 15 to 25 years or more — but only when it's sized correctly and set up by experienced hands. At All Weather Heating & Cooling, we install both hot water and steam boilers from all the major manufacturers, and we'll help you choose the right system for your home's layout, fuel type, and heating demands.
If your existing boiler is aging, inefficient, or struggling to keep up with demand, replacement is often the smartest investment you can make. Today's high-efficiency models can dramatically reduce your heating bills while delivering more consistent warmth throughout your home. Homeowners in West Islip, Amityville, Lindenhurst, and beyond are taking advantage of available rebates — up to $4,500 — to offset the cost of upgrading. We handle the entire process, from system selection to final startup, and we offer flexible financing options so cost doesn't stand in your way.

With the proper professional routine maintenance, boilers can provide many years of service. As they age, they become less efficient and more costly to run. If you notice that happening with your aging boiler, check with our heating and cooling team—it might be time to replace it.
We install a variety of boiler models and will work with you to find the best system to suit your home, lifestyle, and budget.
At All Weather Heating & Cooling, we take the guesswork out of choosing a high-efficiency, quality boiler for your New York home. We calculate your home’s square footage, along with the heating needs of each room, to determine the appropriate size of your needed boiler.
A correctly sized HVAC system will warm your home without wasting energy. A high-efficiency model will save money on utility bills. The higher the efficiency, the more money you will save.

Frequently Asked Questions About Boilers on Long Island
How long does a boiler typically last?
A well-maintained boiler can last 20 to 25 years or more. Regular annual tune-ups, prompt repairs, and proper water treatment all play a role in maximizing your system's lifespan. If your boiler is approaching 20 years old and requiring frequent repairs, replacement is usually the more cost-effective path.
What's the difference between a hot water boiler and a steam boiler?
Hot water boilers heat water and circulate it through pipes to baseboard radiators or radiant floor systems. Steam boilers heat water to the point of steam, which travels through pipes to cast iron radiators. Many older Long Island homes — particularly in communities like Massapequa and Amityville — were built with steam systems. Both types can be serviced, repaired, and replaced by our team.
Why is my boiler making a banging or gurgling noise?
Banging sounds (sometimes called "kettling") are often caused by mineral buildup on the heat exchanger, which traps water and causes it to boil unevenly. Gurgling usually points to air in the system or low water pressure. Both issues are repairable — give us a call at 631-823-1648 and we'll diagnose the problem.
Are there rebates available for a new boiler in New York?
Yes. New York homeowners may qualify for rebates up to $4,500 when upgrading to a high-efficiency boiler, depending on the equipment and fuel type. PSEG Long Island and National Grid both offer incentive programs. We'll help you identify what you qualify for and walk you through the application process.

How do I know if my boiler needs to be repaired or replaced?
If your boiler is under 15 years old and the repair cost is less than half the cost of a new system, repair usually makes sense. If it's older, breaking down repeatedly, or your heating bills have increased significantly, replacement is often the better investment. Our technicians will give you an honest assessment — never a upsell — so you can make the right decision for your home and budget.
