Brooklyn Boiler Service Reviews
Google Reviews: 4.9/5 ★★★★★
Thomas B.
★★★★★
Core Mechanical Group LLC fixed our loud, clanging steam boiler the same day. They flushed the system and replaced a faulty air vent. The heat is now consistent and the pipes are finally quiet again!
Sarah M.
★★★★★
Very thorough annual boiler tune-up. The technician checked everything from gas valves to the expansion tank and even found a small leak we hadn’t noticed. Great peace of mind for the winter.
James P.
★★★★★
Our combi-boiler shut down on a Friday night, and they had a technician here within 90 minutes to fix the igniter. Professional, honest, and clearly experts in modern heating systems.
Boiler FAQ
Common Questions About Boiler Service in Brooklyn
How often should I have my boiler serviced?
We recommend a professional tune-up at least once a year, preferably before the winter season starts. Regular maintenance helps prevent sudden breakdowns and ensures safety.
What causes a boiler to make banging or whistling noises?
This is often caused by “kettling” due to limescale buildup, air trapped in the system, or a failing circulator pump that needs professional attention.
Why is my boiler losing pressure?
Boiler pressure drops are usually caused by a water leak in the system or a faulty expansion tank. A professional should inspect it to find the source of the leak.
Is a yellow pilot light flame dangerous?
Yes, a healthy pilot light should be blue. A yellow flame indicates improper gas burning, which can lead to dangerous carbon monoxide—call for service immediately.
Do you repair both steam and hot water (hydronic) boilers?
Absolutely. We work on classic steam boilers in older brownstones as well as modern, high-efficiency hot water and combi-boiler systems.
What should I do if my boiler stops working suddenly?
First, check your thermostat and circuit breaker. If everything looks normal, call us for an emergency diagnostic to avoid pipe freezes.
Can a regular service really lower my heating bills?
Yes. A clean boiler with a tuned burner transfers heat much more efficiently, significantly reducing your monthly gas usage.
