Common Boiler Problems

Four signs your radiator or boiler needs an experienced technician

Boiler repair | sensational heating & air

A cold Chicago home cannot wait when the heat fails. Before your system cuts out entirely during a brutal winter freeze, look out for these four common issues.

No Heat or Hot water

If your radiators stay cold on a freezing night, a broken motorized valve, faulty pilot light, or a failing thermostat control is usually why. We find the root cause fast to get reliable heat moving through your home again.

Persistent Water Leaks

A leaking boiler drops your system pressure and wastes fuel. Whether it is a cracked internal component or a bad pressure relief valve, we seal the leak before it causes expensive home water damage.

Loud Banging or Whistling Noise

Kettling occurs when lime and sediment build up inside your cast iron heat exchanger. This restricts water flow, makes your boiler become less efficient, and causes deep metallic banging sounds.

Stop the Noise

Low System Pressure

Steam and hot water systems require exact pressure levels to push heat through a Chicago two-flat or bungalow. If your pressure gauge keeps dropping, we will locate the underlying leak or failed expansion tank.
