The heating system in your home or a commercial facility is necessary for the colder winter months. While heat is essential for keeping people warm, it is also vital for the maintenance of your property. Without heat, pipes can freeze, windows can break, and so much more. If you do not have heat, contact an expert in furnace repair in Waterloo.
However, not every apparent issue requires a technician. For example, many homeowners freak out when they smell something burning after turning on their HVAC system for the first time. Is the smell normal? Is it something to worry about?
Is It Normal To Smell Burning?
A slight burning or hot smell does not always warrant a call to a residential furnace repair company. When a system is shut down for a while, like most systems are during the spring and summer months, a minor odour is expected as the system kicks back on.
A stagnant system collects dust throughout. When the furnace kicks back on, it is burning the existing dust within the motor, heating elements, and other components. The burning that takes place after a while of inactivity is considered normal and nonthreatening. Still, that does not mean that all burning smells are natural.
What Smells Are Not Normal?
Whether dealing with residential or commercial furnace repair, some odours are unnatural and require the attention of a seasoned expert. Some smells can indicate problems with specific components, and others can represent issues with entire systems. Homeowners must know the differences between these odours to explain the scent to a technician and determine the feasibility of a repair. Depending on the severity of the damage, a new system might be advisable.
1. Rotten Eggs
Most HVAC systems use natural gas to operate. Natural gas is odourless, which is dangerous, so gas companies add mercaptan to it, producing a rotten egg smell. Without the rotten egg odour, people may not realize they have a gas leak, which can result in death or severe injury.
If you smell rotten eggs when you turn on your furnace or HVAC unit, you should shut it off immediately and call the gas company or a licensed HVAC professional. A crew should arrive on the scene quickly to inspect and repair any issues.
Sometimes, homeowners will turn on their furnace and notice a strong musty or mouldy smell coming from the vents. The odour usually indicates mould growth in the ductwork or evaporator coil. The vents and system will need to be cleaned to eliminate the odour.
Unfortunately, depending on how bad the mould growth is, it often represents more significant problems. You might want to hire a mould remediation company to assess the rest of the property for mould. Sometimes, mould remediation is the only way to rid an entire property of mould risks.
3. Electrical, Metallic, or Plastic
Electrical and metallic burning smells can indicate an overheated blower or another component. The best thing you can do is shut down the system and ask an HVAC technician for assistance. If you continue to run the system with malfunctioning parts, you risk damaging the heat exchanger or other critical components.
The smell of burning plastic is not typical, and it can be hazardous. Plastic and similar materials can release fumes into the air that are toxic. If you smell plastic, shut off the HVAC system, open windows, and contact an HVAC specialist.
