Long Island Boiler Maintenance, Repair & Replacement

Our Technicians Are Licensed & Insured in Wantagh, Nassau & Suffolk Counties

On Long Island, homes are as diverse as the people. From the quaint cottages of Montauk to the sleek modern builds of Garden City, every neighborhood offers unique charm. But one thing stays the same — if the boiler’s out, we all feel the chill. 

Older homes with aging boilers, especially oil-powered systems, can struggle when the temperatures drop. Combine that with aging gas lines in places like Hempstead or power outages when Nor’easters slam the coast, and you’ve got the perfect storm for boiler trouble.

Not to worry — our team has seen it all. Whether your boiler is clunking along for "just one more season" or your high-efficiency unit needs fine-tuning, we’ll get the job done right.

Does My Boiler Need Emergency Repair?

When should you pay attention to boiler trouble? The short answer: sooner rather than later. A slight mechanical hiccup can quickly spiral into a major issue. Here’s a quick rundown of signs your boiler might need a specialist ASAP.

• No Heat or Hot Water: If your radiators are ice-cold or your taps are streaming chilly water, it’s time to call.
• Unusual Noises: Banging, whistling, or hissing sounds can signal issues and may lead to system failure.
• Leaks: Water pooling around your boiler is never good news. It can lead to corrosion or worse.
• Pilot Light Issues: Pilot lights that refuse to stay lit could point to a faulty thermocouple or gas supply problem.
• Skyrocketing Bills: Is your energy bill suddenly climbing? Your boiler might be struggling to keep up.

Don’t wait until things go from bad to worse. We offer same-day and weekend appointments to get your home warm again.

Boiler Repair vs Boiler Replacement

How do you decide whether it’s time to repair or replace something? It can be a tough call, but understanding the key factors can help. Here’s the breakdown to make the decision easier:

When to Repair

• Your boiler’s under 10 years old and showing minor, isolated issues.
• The cost of repairs is less than 50% of the price of a replacement unit.
• No major components, like the heat exchanger, are showing signs of wear or failure.

When to Replace

• Your boiler’s over 15 years old and frequently needs repairs.
• Newer models could save you significantly on your energy bills.
• Replacement parts for your current model are increasingly hard to find.

Preventive Maintenance Tips for Your Boiler

An efficiently running boiler can last for a decade or longer. With regular maintenance, you can avoid sudden breakdowns and keep your boiler’s energy efficiency sky-high. Here are a few tips to keep yours in peak condition:

1. Schedule an annual inspection with a qualified technician.
2. Bleed radiators to remove trapped air each year.
3. Inspect and remove debris around your boiler for optimal airflow.
4. Check the pressure gauge — it should always stay within the recommended range.
5. Insulate any exposed pipes to avoid freezing during Long Island’s cold snaps.
