When the cold hits Brooklyn, your boiler becomes one of the most important systems in your home. A well-maintained boiler keeps you warm, safe, and helps avoid sky-high energy bills. The problem is, most homeowners don’t think about their boiler until it’s too late. That’s where a little routine maintenance can make all the difference.
Common Boiler Problems in Brooklyn Homes
Our borough is filled with older homes, which means older heating systems too. Some of the most common boiler problems we see include:
- Pilot light or ignition issues
- Leaks from valves or aging pipes
- Loud banging or whistling noises (known as “kettling”)
- Low or inconsistent pressure
Catching these problems early can save you from cold nights and costly repairs.
1. Pilot Light or Ignition Acting Up
The pilot light going out is very common on older boilers. Sometimes it’s a simple draft or a dirty nozzle. Other times the thermocouple, which is the safety device that shuts off gas when the flame dies, is worn out. If you’re relighting the pilot over and over, it’s time to call in a professional.
2. Leaks From Valves, Pipes, or Seals
Small drips around the boiler often come from worn seals, corroded valves, or pressure problems. A minor tightening can sometimes help, but corrosion or a bad pressure valve means you need a plumber right away.
3. Kettling, Gurgling, or Banging Noises
If your boiler sounds like a tea kettle about to whistle, that’s “kettling.” It usually happens when limescale or sludge builds up in the system and slows water flow. It’s noisy, wastes energy, and makes your system work harder. Trapped air, pressure problems, or a struggling pump can also cause banging or whistling.
4. Low or Inconsistent Pressure
When the pressure gauge dips below 1 bar or jumps up and down, it usually means there’s a leak somewhere or a part that’s not working correctly. You can try topping up the pressure if your manual allows it, but if the pressure won’t stay steady, that’s a job for a plumber.
5. Frozen Condensate Pipe
During freezing Brooklyn nights, the condensate pipe on modern condensing boilers can ice up. When that happens, the system can’t drain and may shut down completely. The quick fix is to thaw it with warm water and insulate the pipe to prevent it from happening again.
What You Can Do (and What You Shouldn’t)
- Smart DIY checks: Bleed radiators, make sure the thermostat is set correctly, keep an eye on the pressure gauge, and listen for new noises.
- Leave it to the pros: Repeated pilot light failures, leaks you can’t stop, kettling sounds, pressure that won’t hold, or frozen condensate issues that keep coming back.
What You Can Do Yourself
You don’t need to be a pro to keep an eye on your boiler. A few simple steps can go a long way:
- Bleed your radiators so heat flows evenly
- Check your thermostat to make sure it’s working properly
- Keep an eye on the pressure gauge
- Pay attention to new noises, smells, or leaks
If something seems off, it’s always smarter to call a licensed plumber before things get worse.

- Full inspection of all components
