HVAC Operation: Understanding Odours
Posted on November 24, 2017
As we quickly approach the holiday season our senses continue to be filled with wonder; it’s all about the sights, sounds and smells! When it comes to odours especially, the only ones that should be filling your home are those from freshly baked goods and other sweet scents of the season.
Ensuring that your HVAC is running effectively during this season is important in order to keep everyone happy and comfortable, but if you happen to smell something that doesn’t seem quite normal, it’s important to be able to quickly identify and remedy the situation.
The following are some smells which if emitted from your furnace signals immediate professional assistance:
‘A Burning Electrical or Metallic Smell: If you smell any odor similar to an overheated motor this could be a sign your furnace blower motor is seizing up due to worn bearings. This can lead the motor to use excessive voltage and overheat. In addition to the motor overheating it can cause the wires attached to it to melt and produce an electrical hazard. If you smell a burning electrical smell throughout your home, turn off your furnace at the thermostat and call an HVAC technician to inspect your furnace.
Chemical Aroma: Odors that resemble the chemical formaldehyde scent may indicate a cracked heat exchanger, which is a very serious issue. The heat exchanger is the mechanical function inside the furnace that transfers heat from the combustion chamber to the furnace plenum. If the heat exchanger is cracked, poisonousness carbon monoxide fumes can be circulated through the home’s duct work. With that being said, treat any chemical smell with caution and respect, it is always better to be safe than sorry!
Rotten Eggs Smell: The rotten egg odor is a profound indicator that there is a natural gas leak and should immediately be taken care of. Open doors and windows to let fresh air in and evacuate the house. Making sure to stand away from your home, call 9-1-1 and then your gas company.’ (Will Housh, hvac.com)
