Boiler Service, Repairs & Maintenance

If you home doesn’t have a furnace for heat, odds there's a boiler to keep you andloved ones warm during the winter. A boiler system works through hydronic heating as heat from boiled water is in turn radiated into the home. These units are often powered by natural gas or heating oil. The efficiency is measured through annual fuel utilization efficiency (AFUE), the annual heat output of the boiler compared to the total annual fossil fuel energy consumed. Hydronic, or hot water, boilers are more common today than steam boilers, though an older home’s boiler may still produce steam heat.

Common Boiler Repairs

The boiler in a home, once installed and properly maintained, will provide heat and comfort for many years. However, repairs are occasionally needed.


Hard water deposits, such as lime and other minerals, can build up inside, leading to the sound of a kettle boiling. But this time it’s your boiler. Calcium salt from the lime becomes insoluble as the water heats up and settles at the bottom Water trapped in the heat exchanger begins to boil and expand, causing the rattling noise associated with kettling.

Pilot Light Goes Out

The pilot light is generally always lit, but if it goes out more than once in a great while, give us a call. During a boiler maintenance check, our technicians look for a number of causes, such as a draft of air, deposit buildup, or a broken thermocouple.

Leaking and Dripping

Leaks and drips from a boiler can lead to rust and other water damage issues for the unit and surrounding areas.


The older the unit, the older the thermostat, and more potential issues. Older thermostats become less accurate as they age, leading to misread temperature settings or turning the boiler’s heat on or off by itself.

Radiators Not Hot

Air in the radiator will rise to the top of the radiator pipes, giving the illusion of no heat at the top while there is heat at the bottom. Bleeding the radiator often solves this issue, but if not, a technician with Hoveln Heating & Cooling, Inc. can further inspect, diagnose, and repair the radiator.

Boiler Switches Off

A sudden switch off may be caused by a number of reasons, including low water pressure, thermostat issues, and/or air in the system.

Boiler Maintenance

Regular maintenance is the best way to keep the unit operating in an efficient manner and provide peace of mind with safety. When Hoveln Heating & Cooling, Inc. provides boiler services and maintenance, we look at a number of areas for common issues.

  • Properly Connected Vent Pipe & Chimney: Parts and/or pieces of the venting can deteriorate over time, leading to expensive repairs. If an issue is found, a we'll evaluate the situation and let you know of what the best options are for either repair or replacement.
  • Physical Soundness of the Heat Exchanger: Water leaks from the heat exchanger are easy to spot. However, combustion gases can mix with air in the home with a leak, leading to a potential safety issue requiring immediate attention.
  • Combustion Efficiency Test: This test checks for how effectively the heat content of fuel is transferred into useable heat. The concentration of stack temperature and flue gas oxygen (carbon dioxide) are the main signs of combustion efficiency. Stack temperature is the temperature of the combustion gases, dry and water vapor, leaving the boiler. A lower stack temperature means your boiler is effectively transferring heat from the combustion gases.

Boiler Installation

Central Illinois residents have trusted us for boiler installation for four decades. Steam or hot water, we help you choose the unit best suited for your home and needs prior to installation. Our technicians evaluate the home, its needs and capacity, and your expectations to suggest a high-quality boiler.

Choosing the Right Boiler For Your Home

As with having a furnace which properly fits your home, the same goes for a boiler. The capacity is measured in British Thermal Units (BTUs) and every home has a BTU requirement specific to its:

  • Geographic location
  • Climate
  • Number of windows and doors
  • Quality and amount of insulation

Installing a boiler with the correct capacity will weigh heavily into the overall efficiency of the unit. Our technicians will determine the current venting situation and/or additional venting needed for a new boiler.
