Boiler Upkeep and Servicing: Tips from an HVAC Technician

As an heating professional, I often see boilers in requiring repair and maintenance. A efficient boiler doesn’t just heats more effectively but also has an extended lifespan. Here’s a set of tips on boiler repair and maintenance, covering frequent problems, simple troubleshooting, and when to get in touch with a licensed HVAC technician.

Common Boiler Problems

Boilers can have various problems over time. Here are some of the common problems I encounter in my work as an HVAC technician:

  • Lack of Heat: When your boiler doesn’t provide heat, it may be due to a problem with the thermostat, low system pressure, or a damaged valve or diaphragm.
  • Unusual Noises: Banging or gurgling sounds from the boiler mean trapped air, a build-up of sludge, or even a worn part.
  • Decreasing Pressure: A decline in system pressure can prevent your boiler from operating properly. Low pressure could be due to a failing part.
  • Pilot Light Won’t Stay Lit: Older boilers using pilot lights may suffer issues like flame loss due to drafts, a worn thermocouple, or a blocked fuel inlet.
  • Control Panel Issues: Sometimes, the thermostat isn’t working correctly, which impacts temperature adjustment.

Essential Boiler Care

Routine upkeep is essential to keeping your boiler running at optimal levels. Here are my top maintenance tips that can keep your boiler in top condition:

  1. Monitor Boiler Pressure: Your boiler needs to maintain 1 to 1.5 bars of pressure. If the pressure goes down, use the filling loop to increase the correct pressure. Always check not to over-pressurize to keep the system safe.
  2. Bleed the Radiators: Air bubbles in the radiators impede hot water flow. Use a radiator key to bleed out the trapped air, and ensure pressure is back to normal.
  3. Clear the Surrounding Area: Debris can get into the boiler, especially if it’s near materials. Removing obstacles improves performance.
  4. Flush the Boiler System: Sediment and sludge collect over time, affecting efficiency. A professional can flush the system to eliminate sludge, which enhances performance.
  5. Plan for Regular Inspections: A yearly inspection by a qualified HVAC technician is key for identifying incipient issues before they become serious. A trained technician can evaluate the overall system, address any wear and tear, and verify everything is working well.

When a Pro is Necessary for Boiler Issues

While many boiler checks can be done by property owners, specific boiler problems require professional attention. Here are some situations where calling an HVAC professional is a must:

  • Moisture Around the Boiler: A boiler dripping water shows a serious issue. Water issues can lead to electrical hazards, so it’s safest to call in without delay.
  • Burner Won’t Ignite: If the pilot light fails repeatedly, it might be a problem with the thermocouple, gas valve, or ignition system. Certified technicians should handle these components to ensure safety.
  • Loud Noises: Consistent banging, whistling, or gurgling may mean a pressure problem. A professional inspection is necessary.
  • System Won’t Maintain Pressure: If your boiler is constantly losing pressure, a valve might be malfunctioning that needs professional diagnosis.

Final Thoughts

Keeping your boiler well-maintained helps ensure a reliable heating system. Consistent care and simple attention help prevent future issues. For troublesome problems, don’t hesitate to call a licensed HVAC technician—our job in making sure your heat works at its best all year long.
