An Annual Boiler Tune-Up Helps Keep Your System Running Safely & Efficiently

Boilers function best when they’re regularly serviced and cleaned. A neglected system slowly loses its ability to keep your home comfortable at the same level of efficiency it once did. Heating bills go up as efficiency goes down. An annual boiler inspection can also identify small issues that can turn into big problems if your equipment breaks down on a frigid night when you need it most.

Safety is a concern with your boiler. The combustion process needs to be checked yearly to ensure safe operation. Gas leaks, high carbon monoxide levels, and improper drafting can be dangerous if not addressed.

Get peace of mind by scheduling your boiler maintenance now.

What’s Included in Your Boiler Tune-Up?

Our evaluation starts with you, not our checklist. We always begin by having a brief discussion with you to gain an understanding of what’s important for you.

  • How does the system perform when you need it most?
  • What areas of your home are hard to heat?
  • Are there any unusual noises or odors?
  • Is there anything that you would like me to pay special attention to while I’m here?

From there, our licensed HVAC technician will perform an inspection and tune-up of the entire system.

 

Standard Cast Iron Boiler Inspection

  • Verify accuracy and proper operation of the thermostat
  • General observation of work area for venting integrity and water leaks
  • Apply Brady gauge to monitor system pressure while off and while running during inspection
  • Verify the accuracy of pressure temperature gauges
  • Perform combustion analysis to ensure safe and proper combustion
  • Measure draft pressure to ensure safe venting
  • Check all venting for proper pitch, deterioration, or leaks
  • Check boiler pumps for abnormal noises, amp draw, and proper operation
  • If applicable, oil motor and bearing assembly
  • Remove burners and pilot assembly, clean with furnace brush, and replace thermocouple (if applicable)
  • Clean flame sensor and ignition rod
  • Perform a visual inspection of the heat exchanger for excessive rust, leaks, holes, or blockages
  • Verify proper operation of the relief valve
  • Verify sizing and proper operation of the expansion tank
  • Inspect piping and flanges for leaks
  • If applicable, verify proper operation of all zone valves
  • If applicable, verify proper freeze protection levels

High Efficiency Boiler Inspection

  • Verify proper operation of the thermostat
  • General observation of the work area for venting integrity and water leaks
  • Apply Brady gauge to monitor system pressure while off and while running during inspection
  • Verify accuracy of the pressure temperature gauges
  • Perform combustion analysis in both high and low fire to ensure safe and proper combustion
  • Check boiler pumps for abnormal noises, amp draw, and proper operation
  • Remove and clean burners
  • Clean heat exchanger with CLR dilution, brush and flush to ensure channels are clear
  • Flush condensate drain and trap
  • Check for any deficiency in the refractory breaking apart or coming in contact with condensate
  • Inspect swirl plate and check for plastic deterioration or excessive noise
  • Clean flame sensor and ignition rod
  • If in-floor heating is present, verify proper operation of the mixing valve and ensure correct water temperature
  • Verify proper operation of the relief valve
  • Verify sizing and proper operation of the expansion tank
  • Inspect piping and flanges for leaks
  • If applicable, verify proper operation of all zone valves
  • If applicable, verify proper freeze protection levels
 

 
All inspections include a service report with a prioritized list of recommendations (if necessary). Our goal is to leave the system working safely and more reliably but also improving performance. Our thorough evaluations of the entire system can uncover reasons for uncomfortable rooms, inefficient operation, and also extend the lifespan of the equipment.

What’s a combustion analysis?

Unlike many companies doing furnace and boiler inspections, every heating system tune-up done by Althoff Industries includes a combustion analysis. We do it because it’s the only reliable way to assure the efficient and safe operation of your gas fired appliance.

All of our technicians are equipped with an electronic combustion analyzer. This analyzer measures oxygen and carbon monoxide levels along with the temperature of the flue gas. This information is important for the following reasons:

  1. The first priority is to assure your safety by making sure carbon monoxide levels aren’t excessively high. Levels that are outside of the manufacturer guidelines can be dangerous.
  2. It helps us uncover hidden problems that lead to a breakdown that aren’t possible to diagnose without having a combustion analyzer.
  3. It allows us to accurately measure the true efficiency of your heating system.
  4. It allows us to correct issues related to over firing and under firing. Both cause poor performance and shortened lifespan of your equipment.

Why is testing draft important?

Draft is required to remove the flue gasses from the heat exchanger on all atmospheric and draft induced appliances. Verifying draft and checking for spillage is an important safety consideration. All Althoff technicians are equipped with draft gauges that specifically measure draft pressure inside the flue. If improper draft is found, the cause should be remedied to protect the homeowners from carbon monoxide but also proper operation of the equipment.

The three most common reasons for improper draft are:

  1. A blocked or restricted flue
  2. Lack of combustion air
  3. Building depressurization
