When Calgary’s temperatures drop, a reliable furnace is essential to keeping your home warm and comfortable. But like any hardworking appliance, furnaces can develop issues over time.
Ignoring early warning signs can lead to costly breakdowns or even complete system failure. Knowing when to schedule a furnace repair in Calgary can save you from unexpected discomfort and expensive emergency repairs.
Weak or No Heat Output
If your furnace is running but not producing enough heat, it could be due to a faulty thermostat, a clogged air filter, or problems with the burner.
Start by checking the thermostat settings and replacing the air filter. A professional inspection can diagnose and fix underlying mechanical or electrical problems if the issue persists.
Unusual Noises
Furnaces should operate with minimal noise. If you hear banging, squealing, or rattling sounds, it could indicate issues like:
- Loose or broken components
- Blower motor problems
- Ignition issues
A loud banging noise when the furnace starts may indicate delayed ignition, a serious safety hazard. Addressing these sounds early prevents further damage and ensures safe operation.
Frequent Cycling
Does your furnace turn on and off more frequently than usual? This short-cycling behaviour may be caused by:
- A dirty air filter restricting airflow
- A malfunctioning thermostat
- An oversized or improperly installed furnace
Checking and replacing the air filter is a good first step. If the problem continues, a professional assessment can determine whether furnace repairs or adjustments are needed.
Rising Energy Bills
If your heating bills are climbing without a significant change in weather or usage, your furnace may be working harder than necessary due to:
- Dirty filters reduce efficiency
- Leaky ductwork
- A failing or aging furnace
Routine maintenance and timely furnace repair in Calgary can help optimize energy efficiency and keep heating costs under control.
Yellow or Flickering Pilot Light
A healthy furnace pilot light should burn blue. If it’s yellow, flickering or going out frequently, this could indicate a carbon monoxide issue or an imbalance in the gas mixture. Carbon monoxide leaks are dangerous and should be addressed immediately by a professional.
Poor Air Quality and Unusual Odours
A malfunctioning furnace can impact indoor air quality, leading to dust buildup, dry air, or strange odours like:
- A burning smell (which may indicate overheating)
- A musty smell (potential mould in ductwork)
- A rotten egg smell (a possible gas leak—turn off the furnace and seek emergency assistance immediately)
If these odours persist, scheduling a furnace inspection is crucial for safety and efficiency.
Furnace Won’t Start or Struggles to Stay On
If your furnace won’t start or keeps shutting off unexpectedly, the issue could be:
- A faulty ignition system
- A tripped circuit breaker
- A clogged air filter or blocked vents
Resetting the circuit breaker and checking filters may solve the problem, but professional furnace repair is necessary if the furnace still won’t stay on.
