Winters can get harsh, and without an efficiently working heating unit, you’ll be freezing in the cold. A furnace transfers heat to the living space through an intermediary distribution system that keeps your entire house warm and cozy. You must call for repairs and maintenance regularly to ensure safe and efficient heating throughout winters.
Common issues with your furnace
Some of the common issues that trouble you in case you do not call for regular repairs and check-ups are:
- The furnace isn’t receiving power
If your thermostat is operating and its settings are correct, you may have a problem with the wiring or breaker itself.
- A grinding or scraping sound
If the blower produces a rumbling, rattling, squeaking, grinding, or scraping noise, it may be because of your ball bearings. They may have worn out, and you should turn off the unit immediately. To fix this, you’ll need some help from a qualified Calgary HVAC professional. It may also be caused due to a slipped or worn-out blower belt.
- Pilot light or ignition issues
A misbehaving thermocouple or a clogged pilot orifice, or your flame setting may be too low, which will eventually lead to a defective safety switch.
- Low heating
Clogged filters/ burners restrict proper airflow, which makes your furnace work harder. So it can lead to the heat exchanger overheating that will eventually shut down your unit. If your burners get clogged, they can’t release sufficient natural gas to create combustion—which means you’ll get no heat. Burners should produce blue flames. Any other color, such as bright yellow or dark orange, shows the presence of debris in the mix.
- Weird smell
A cracked heat exchanger hampers your furnace’s ability to do its job efficiently. It also releases deadly carbon monoxide into your home.
Signs to spot a cracked heat exchanger
- Soot on the inside of your furnace
- A strong, unpleasant odor
- Water on the floor around the furnace
- People experiencing headaches, irritated eyes, nausea, disorientation, or flu-like symptoms indicate carbon monoxide poisoning. If you suspect your furnace has a cracked heat exchanger, shut it down immediately. Call our professional HVAC experts for a check-up.
- Faulty blower
If your blower fan runs continuously, your limit control switch may be to blame. This switch directs heat from the furnace to the ducts and shuts down the system when it gets too hot. If the unit never shuts off, it means your limit switch needs to be adjusted or replaced—which is a job for an HVAC professional.
- The furnace doesn’t blow air
If your furnace is coming on, but it doesn’t seem to be blowing out air, you may have a broken blower fan belt.
