Boilers are honestly one of the most reliable heating systems out there. Fewer moving parts than a furnace, no blower motor to fail, no ductwork to leak. But “reliable” doesn’t mean “maintenance-free,” and we’ve seen way too many homeowners learn that lesson the hard way. A boiler that hasn’t been serviced in five years is a boiler that’s going to surprise you on the coldest night of the year.

We service a lot of boilers in the older neighborhoods around Crown Point, IN, and the established homes in Saint John. Some of these systems are 20+ years old and still running strong — but only because someone’s been maintaining them. The ones that get neglected end up with scale buildup, corroded components, and efficiency losses that add up to hundreds of dollars a year in wasted fuel. Preventative maintenance reduces the chances you’ll need our 24/7 emergency services, but if you ever do, we’re ready.

What's Included in a Boiler Service Visit

Our annual boiler maintenance covers the full system:

  • Inspect the heat exchanger and combustion chamber
  • Check and adjust the burner for optimal performance
  • Test the pressure relief valve
  • Inspect the expansion tank
  • Flush sediment from the system
  • Check water pressure levels
  • Test all safety controls
  • Inspect the flue and venting
  • Verify the thermostat is calibrating correctly
  • Bleed any air trapped in the baseboard and radiator lines


The whole visit takes about an hour, sometimes a little longer on older or larger systems. We document everything and let you know if there are any components that are showing wear so you can plan ahead instead of getting blindsided by a breakdown. 

Boiler Safety Inspections

Boiler safety is something people tend to take for granted because boilers are generally safe when maintained properly. But a malfunctioning pressure relief valve, a blocked flue, or a cracked heat exchanger can create real hazards — including carbon monoxide exposure and, in extreme cases with older steam systems, overpressure situations.

Our safety inspection covers all of this. We test the pressure relief valve to make sure it opens at the correct pressure, check CO levels in the flue gases and around the unit, inspect venting for obstructions or deterioration, and verify all safety interlocks are functioning. If we find anything that poses an immediate safety concern, we’ll tell you straight up and explain your options.

Signs Your Boiler Needs Maintenance

  • Rising energy bills without increased usage
  • Uneven heating between rooms or radiators
  • Strange noises like banging, whistling, or kettling sounds
  • Visible leaks or corrosion around the unit
  • Radiators that need frequent bleeding
  • Pilot light that frequently goes out
  • The system takes longer to heat your home than it used to


If you’re experiencing any of these issues, scheduling maintenance now can prevent a full system failure later. And if your boiler does shut down unexpectedly, our 24/7 emergency services are available to restore heat as quickly as possible.

Benefits of Regular Boiler Maintenance

  • Lower monthly heating costs through improved efficiency
  • Extended system lifespan by preventing premature wear
  • Fewer unexpected breakdowns during winter
  • Safer operation with tested safety controls
  • Maintained manufacturer warranty compliance
  • Better heat distribution throughout your home
  • Early detection of problems before they become expensive 

How Often Should You Service Your Boiler?

Once a year, ideally in early fall before the heating season kicks in. This gives us time to catch and fix any issues before you actually need the system running every day. If you’re on our American Comfort Club membership, your annual boiler service is included along with priority scheduling and discounts on any repairs.

Crown Point’s water quality can affect boiler performance over time. Mineral content in the water supply leads to scale buildup inside the heat exchanger, reducing efficiency and potentially causing hot spots that shorten the system’s lifespan. Regular maintenance includes flushing sediment and checking for scale accumulation before it becomes a problem.

Yes. We service all types of residential boilers, including hot water baseboard systems, steam radiator systems, and radiant floor heating boilers.

Yes. Regular maintenance keeps your boiler running at peak efficiency. Scale buildup, dirty burners, and improper pressure all force your boiler to work harder and burn more fuel. A well-maintained boiler can save 10-20% on heating costs.
