1. No Heat or Hot Water
This is the most obvious sign of a problem. If your radiators stay cold or you’re getting no hot water, your boiler may have a failed thermostat, pump issue, or pressure fault.
2. Strange Noises (Banging, Gurgling, or Whistling)
Unusual sounds can signal air in the system, limescale buildup, or worn-out parts. Don’t ignore these sounds—your boiler may be working harder than it should.
3. Boiler Leaks or Low Pressure
Water pooling around the unit or consistently low pressure can point to seal damage or internal component failure. It’s a common issue we fix daily across Montreal homes.
4. Yellow or Flickering Pilot Light
Your pilot light should burn blue. If it’s yellow, it may indicate poor combustion or a possible carbon monoxide leak—call a technician immediately.
5. Radiators Not Heating Evenly
If some radiators are cold while others are hot, the issue could be trapped air, sludge buildup, or a circulation problem within your system.
