Common Signs of a Faulty Gas Boiler

Wondering if your boiler needs a repair? Here are some common warning signs:

No Heat or Hot Water — If your boiler isn't heating your home or water, something's wrong.
Strange Noises — Banging, whistling, or gurgling sounds could indicate trapped air, low pressure, or a faulty pump.
Leaking or Dripping Water — Even small leaks can lead to bigger (and costlier) problems if left unchecked.
Fluctuating Boiler Pressure — If your boiler keeps losing or gaining pressure, there might be an underlying issue.
Unusual Smells — A gas or burning smell could indicate a dangerous issue—shut off your boiler and call a professional immediately.
Frequent Pilot Light Outages — A pilot light that won't stay on might be due to a faulty thermocouple or gas supply issue.

I had my dryer vent cleaned by Dean and his guys. They were very fast and professional. My vent is on the 3rd floor so it required a 40' ladder. They were able snake the entire vent pipe, which is about 30'. Clothes are drying much faster. I highly recommend Dean's Service.
Joe D. Philadelphia, PA
The technician from Dean's service was able to come to my house the same day and repair my air conditioner unit. He was courteous and very professional. Thank you so much for the quick service and fair pricing!

Frequently Asked Questions

Can a gas boiler be repaired, or does it need to be replaced?

In many cases, a gas boiler can be repaired, especially if the issue is minor, like a faulty valve or thermostat. However, if your boiler is old, inefficient, or has major damage, replacing it may be the more cost-effective option in the long run.

Is it safe to use my gas boiler if it's leaking water?

No! A leaking boiler could indicate pressure issues, corrosion, or a faulty seal. Continuing to use it could lead to further damage or even a breakdown.

What causes a gas boiler to lose pressure?

Common causes include leaks, faulty pressure relief valves, air in the system, or recent radiator bleeding.

What should I do if my gas boiler stops working?

First, check your thermostat, pressure gauge, and power supply to see if there's an easy fix. If everything seems fine but your boiler still won't turn on, contact a professional to diagnose and repair the issue.

How often should I have my gas boiler serviced?

You should have your gas boiler serviced at least once a year to ensure it's running safely and efficiently. Regular servicing helps prevent breakdowns, improve energy efficiency, and extend the lifespan of your boiler.
