Top Signs Your Furnace is About to Break Down
Recognizing these signs early on can help you avoid a cold emergency and may even save you from costly repairs or a full furnace replacement.
As the colder months roll in, your furnace becomes essential for home comfort, especially in Alberta. Recognizing early warning signs of furnace failure can prevent costly emergencies. Below are the top things you need to look for that may indicate that your furnace needs professional attention. At Aqua Plumbing and Heating Ltd. we have dealt with thousands of furnaces so we know a lot about this particular topic.
1. Inconsistent Heating or Uneven Temperatures
Uneven heating across rooms or temperature fluctuations often signal furnace issues. Common causes include:
- Clogged air filters: Restricted airflow reduces heating efficiency.
- Leaking ducts: Escaping heated air causes imbalances.
- Thermostat issues: Malfunctioning sensors disrupt temperature control.
2. Strange Noises Coming from the Furnace
Unusual sounds like these warrant immediate inspection:
- Rattling/banging: Loose or broken components.
- Squealing: Worn fan belt or motor strain.
- Humming: Electrical system malfunctions.
3. The Furnace is Blowing Cold Air
Potential causes include:
- Faulty thermostat readings
- Pilot light/ignition failures
- Dirty burners
Address promptly to avoid further damage.
4. Increased Energy Bills
Spikes in heating costs may stem from:
- Clogged filters
- Aging furnace inefficiency
- Dust buildup on critical parts
5. Frequent Cycling
Short cycling (rapid on/off bursts) can result from:
- Dirty filters causing overheating
- Thermostat errors
- Component wear
6. The Furnace Gives an Unpleasant Smell
In several cases we have seen wires shortcircuit inside the furnace which melts plastic and creates a smell that some describe as like burning paper or hairspray. Sometimes animals can get inside a furnace and that can lead to smells. Other times water gets inside a furnace and creates smells and other major issues.
7. Yellow or Flickering Pilot Light
A blue flame is healthy. Yellow/flickering flames may indicate gas leaks or combustion issues—seek urgent professional help.
