Top 7 Signs Your Furnace Needs Repair in Calgary
A malfunctioning furnace can cause rising energy bills, uneven heating, and strange noises; all indicators of a potentially serious problem requiring attention.
Keep reading to learn the key warning signs and when it’s time to call a professional.
Sign #1: Unusual Sounds Coming From Your Furnace
If your furnace starts making banging, rattling, or squealing sounds, it usually signals a mechanical issue. Loose components, fan belts, or failing motors are often the cause of these noises. Addressing these issues quickly can prevent further damage and costly repairs.
Sign #2: Inconsistent or Uneven Heating Throughout Your Home
Rooms that feel warmer or colder than others typically indicate airflow or duct issues. A furnace struggling to distribute heat evenly may have a dirty filter, blocked vents, a failing blower, or internal component concerns. Uneven temperatures can make your space uncomfortable and signal that your furnace is under stress.
Sign #3: Sudden Increase in Energy Bills
A sudden spike in heating costs typically indicates an inefficient furnace. Dirty filters, worn parts, or a failing system can force your furnace to work harder to maintain temperature. Preventative maintenance and timely repairs can lower energy waste and keep bills in check.
Sign #4: Furnace Cycles On and Off Frequently
Frequent cycling, known as short cycling, can be a sign of overheating, a clogged filter, or a malfunctioning thermostat. This behaviour puts extra strain on your furnace and can shorten its lifespan. Getting a professional to inspect the system can prevent long-term damage.
Sign #5: Strange or Burning Odours When Heating
A musty, burning, or chemical smell from the furnace when running can indicate dust buildup, overheated components, or even a gas leak. Never ignore unusual odours, as they can pose safety risks to your home and family. Certified technicians can identify the source and safely correct the problem.
Sign #6: Poor Airflow or Weak Heat Output
If warm air feels weak or airflow seems restricted, a failing blower motor, dirty ducts, or blocked vents may be the cause. Poor airflow can create warm and cold areas in your home, reducing comfort and forcing the furnace to work harder, increasing the risk of failure. Professional inspection can restore proper heating performance.
Sign #7: Yellow or Flickering Pilot Light Instead of Blue
A blue flame generally indicates healthy combustion, while a lazy yellow or flickering flame can signal incomplete burning or the presence of carbon monoxide. CO is a serious safety concern and requires immediate attention from a certified HVAC professional. Never attempt to fix this on your own.
