Common warning signs include no heat or hot water, strange noises like banging or whistling, water leaks, a frequently extinguished pilot light, or uneven heating throughout your home. If your boiler is slow to respond, your radiators stay cold, or you notice pressure issues, it's time to schedule a service call with RJ's.
These sounds often come from air trapped in the system, sediment buildup in the tank, or kettling, which occurs when limescale accumulates on the heat exchanger. These issues reduce efficiency and can eventually lead to breakdowns. A technician can bleed the system, flush sediment, or descale internal components as needed.
Yes! RJ's services both hot water and steam boiler systems, including those with radiators, baseboard heaters, or radiant floors. Many older homes in Barrington, IL still rely on steam, and our technicians are trained to handle these systems with proper balancing, venting, and trap maintenance.
The most frequent issues we encounter include low system pressure, pilot light problems, faulty thermostats, worn circulator pumps, and expansion tank failures. In steam systems, improper venting and stuck radiator valves are also common. We carry parts for most brands and can often complete repairs in a single visit.
Annual boiler maintenance is recommended—ideally in the fall before the heating season begins. This ensures your system is clean, safe, and ready to operate efficiently during the coldest months of the year.
