Your heating system plays a crucial role in maintaining your home’s comfort, especially during colder months. But how do you know when it’s time to call a professional? Here are five common signs that your heating system may need servicing.
1. Unusual Noises
Banging, clanking, or hissing sounds from your boiler or radiators could indicate a problem with your heating system, such as trapped air, loose components, or a failing pump.
2. Inconsistent Heating
Are some rooms warmer than others? Uneven heating often signals issues with your system, like a malfunctioning thermostat or clogged pipes.
3. High Energy Bills
A sudden spike in your energy bills could mean your heating system is working harder than it should due to inefficiency or faults.

4. Yellow Pilot Light
If your boiler’s pilot light is yellow instead of blue, it may be producing carbon monoxide—a serious safety hazard that requires immediate attention.
5. Frequent Breakdowns
If your heating system is breaking down frequently, it’s likely time for a professional inspection or replacement.
