What Serious Problems Can Emerge with an HVAC Boiler?

Your HVAC boiler is one of the most important appliances in your house. It keeps your home warm and cosy during the chilly winter months and provides hot water throughout the year. However, like all other appliances, your boiler may encounter a range of problems. Some of these problems may be relatively minor and easy to fix, while others may be more serious and require professional assistance. So, what are some of the most serious problems in this situation, and what can you do about them?

Leaking Boiler

If you notice water around the base of your boiler or a steady trail of water running down the side of it, you probably have a leak. A leaking boiler can occur for many reasons, including loose connections, damaged parts and corrosion. It goes without saying, but a leaking boiler is not only an indicator of a serious problem, but it can also be potentially dangerous. If you suspect a leak, you should immediately turn off the boiler and contact an HVAC specialist for some emergency boiler repair.


Kettling refers to a situation where your boiler begins to make a strange noise that resembles a boiling kettle. Kettling can occur due to the build-up of limescale inside the system, which causes the water to heat up unevenly and create steam. This can cause significant damage to your boiler, including cracks, which could lead to major issues, such as gas leaks. The best way to avoid kettling is to have regular maintenance and cleaning from an HVAC professional.

Pilot Light Problems

The pilot light is a small flame that ignites the natural gas in a boiler to produce heat. If the pilot light goes out, your boiler won't work properly. If the light keeps going out despite multiple attempts to reignite it, it may imply the presence of looseness in the connections, worn-out thermocouples or even a clogged pilot light. It's always wise to let an HVAC technician inspect your boiler and determine the leading cause of the problem.

What You Should Do Now

Your HVAC boiler is essential to your home's comfort and safety. While it remains largely invisible and unobtrusive, it can encounter a range of serious problems that require immediate attention. From leaking boilers to kettling and pilot light issues, it's essential to let an experienced HVAC technician diagnose and fix these problems to avoid putting yourself and your family at risk.
