Routine boiler maintenance is one of the most cost-effective ways to improve your home’s energy efficiency and winter comfort. Whether you are looking to optimize a brand-new unit or extend the life of an aging radiant heating system, professional maintenance is key to ensuring your HVAC system operates exactly as it should. Meyer Heating & Air provides expert boiler tune-ups across St. Louis, ensuring your equipment is perfectly integrated with your heating system for peak winter performance.
Don’t risk mid-winter breakdowns or DIY fixes that could damage your controls or cause water leaks. Our professionals ensure your system is cleaned safely, calibrated accurately, and tuned for the best performance.
The Importance of Professional Boiler Maintenance
Modern heating systems require precise calibration, cleaning, and safety testing to communicate optimally with your HVAC system and keep your home safe. Choosing a professional for your boiler maintenance ensures:
- System Protection: We resolve common issues like mineral buildup, faulty circulator pumps, and ignition failures before they lead to short cycling, overheating, or component failure.
- Optimal Efficiency: A well-maintained heating system does not have to work as hard, which lowers your monthly utility bills and ensures even, comfortable radiant heat throughout your home.
- Safety Assurance: For gas boilers, we inspect the heat exchanger, test safety switches, and verify proper venting to ensure no harmful carbon monoxide gas leaks into your home.

What to Check Before You Call Us
Save yourself time and money by checking these common, easy-to-fix culprits before scheduling a diagnostic or maintenance visit:
- Check your thermostat: Ensure it is set to “Heat” and that the temperature is higher than the current room temperature.
- Check the boiler pressure gauge: Most hot water boilers should have a pressure reading between 12 and 15 psi. If it is too low, the system may not fire up.
- Check the circuit breaker: Ensure the breaker connected to your boiler has not tripped.
- Verify the gas valve: If you have a natural gas boiler, make sure the gas supply valve is in the open position.

At Meyer Heating & Air, we stay on the cutting edge of indoor climate technology. We offer maintenance services for a wide variety of models, including:

Our Boiler Maintenance Process
A detailed boiler tune-up is designed to optimize your system’s performance, enhance safety, and identify any potential issues. Here’s what our Meyer Heating and Air technicians typically do during a boiler maintenance visit:
- Thorough Visual Inspection: We visually inspect all accessible components of your boiler and associated piping for signs of wear, corrosion, leaks, or damage.
- Clean Burners & Heat Exchanger: We clean burners for efficient combustion and inspect/clean the heat exchanger to ensure optimal heat transfer and prevent dangerous blockages.
- Check Ignition System: We test the ignitor or pilot light for proper function, ensuring your boiler starts reliably.
- Inspect Flue and Venting System: We verify that the flue pipe is clear and properly sealed, ensuring safe expulsion of combustion gases.
- Test Operating Pressures & Temperatures: We measure and adjust water and gas pressures to manufacturer specifications for safe and efficient operation.
- Inspect Circulating Pump(s): We check the pump’s operation and lubricate as needed to ensure proper hot water circulation through your system.
- Check Expansion Tank: We verify the integrity and proper charge of the expansion tank, which accommodates water volume changes as it heats and cools, maintaining stable pressure.
- Condensate Drain Inspection & Cleaning (for condensing boilers): We clear any blockages from the condensate drain line, preventing potential water leaks and efficiency loss.
- Test Safety Controls: We test all critical safety devices, including pressure relief valves, high-limit switches, and low-water cut-offs, to ensure they function correctly.
- Test for Gas Leaks & Carbon Monoxide: For gas boilers, we conduct rigorous checks for any gas leaks around connections and test for carbon monoxide emissions, ensuring your home’s safety.
- Bleed Radiators (if accessible and necessary): We may bleed air from accessible radiators to ensure even heat distribution.
- Provide Detailed Report: You’ll receive a comprehensive report on our findings, along with any recommendations for repairs or optimizations, giving you full transparency about your boiler’s condition.
