  • 4 min read

When your home’s boiler starts acting up, it can be stressful. You want it fixed quickly and done right. That’s where we come in. At Left Hand Thermal, we’re your neighbors and expert technicians, ready to help with honest advice and quality work. This guide will walk you through common boiler issues, how to spot them, and what to expect when you call for professional help.


Understanding Your Boiler - A Simple Boiler Troubleshooting Guide


Boilers are the heart of your home’s heating system. They keep you warm during cold Colorado winters. But like any machine, they can have problems. Knowing the basics helps you catch issues early and avoid costly repairs.


Here are some common signs your boiler might need attention:


  • No heat or hot water: This is the most obvious sign. If your radiators or taps aren’t heating up, your boiler might be broken.

  • Strange noises: Banging, whistling, or gurgling sounds can mean air in the system or a failing part.

  • Leaks: Water pooling around the boiler is a warning sign.

  • Pilot light issues: If the pilot light keeps going out or looks yellow instead of blue, it could be unsafe.

  • Pressure problems: Low or high pressure can cause the boiler to shut down.


If you notice any of these, it’s time to act. Trying to fix it yourself can be risky and might make things worse.

How much is a typical boiler repair?


One of the first questions we hear is about cost. Boiler repairs can vary widely depending on the issue. Here’s a rough idea:


  • Minor repairs (like fixing a pilot light or bleeding radiators): $100 - $300

  • Parts replacement (such as thermostats, valves, or pumps): $300 - $700

  • Major repairs (like heat exchanger or control board replacement): $700 - $1,500 or more


Keep in mind, these are ballpark figures. The exact price depends on your boiler’s make, model, and the problem’s complexity. We always provide a clear estimate before starting any work. No surprises.


Regular maintenance can help avoid big repair bills. We recommend scheduling a yearly check-up to keep your system in top shape.


Tips for Maintaining Your Boiler Between Repairs


Taking care of your boiler can extend its life and improve efficiency. Here are some simple steps you can do yourself:


  • Check the pressure gauge monthly. It should usually be between 1 and 2 bars.

  • Bleed your radiators if they feel cold at the top but warm at the bottom.

  • Keep the area around the boiler clear of clutter and dust.

  • Listen for unusual noises and note any changes in heating performance.

  • Schedule annual professional servicing to catch small issues early.


If you’re unsure about any of these, just give us a call. We’re happy to guide you through basic care or come out for a check-up.
