Let’s Tackle Your Boiler Issues

There’s no convenient time for you to experience an issue with your boiler – you rely on it for heating and hot water! Some of the most common issues to keep an eye out for include:

  • Leaking
  • Radiator problems
  • Loss of thermostat control
  • Inconsistent pilot light
  • A boiler that won’t start
  • Low pressure

When your boiler starts acting up, that’s where we come in to help. If you spot water around the heating system, that’s an immediate red flag – it could be corrosion, loose joints, or high pressure causing trouble. Keep an eye on the built-in gauge; a reading below “1” means your boiler is not functioning properly. Uneven radiator heating? It could be sludge or air build-up. If you’re noticing that your thermostat is unreliable, it could be a bad connection or signal interference. Try moving it closer to the boiler, and if that doesn’t cut it, give us a shout. Pilot light issues that aren’t caused by a tripped fuse are another good indicator that it’s time for some help. We’ve got your boiler’s back!

This company is AMAZING. They came out to repair our furnace, and unfortunately found a critical safety issue which required immediate same day replacement. The tech explained the issue simply and in a way that I could understand. They were also extremely gracious about working…

Couldn’t of asked for a better experience working with Taylor and the whole team at Thelen Mechanical. We were in a emergency situation and they went above and beyond to get our new furnace installed the very next day. Would 100% recommend them.

How does a boiler work?

A boiler uses oil or natural gas to heat water or make steam. This hot water or steam is piped through your home to distribute heat usually through radiators or baseboard radiators.

How will I know if my boiler is starting to fail or needs a repair?

There are several issues to note including a failing pilot light, a boiler that won’t start, poor pressure, a thermostat that doesn’t work, leakage, and radiator problems. These are all signs that a part needs to be fixed or a full replacement is in order.

Do I have a furnace or a boiler?

If you have radiators, you have a boiler system. If you have ductwork or air vents, you have a furnace. It’s possible you have a boiler if you have floor heating. A good sign is looking for what your system is connected to – pipes or ductwork. If it’s pipes, you have a boiler. If it’s ductwork, it’s a furnace.
