Have you ever turned on your heat and noticed a strange burning smell? If so, you're not alone. Many homeowners experience heater smells like burning when first turned on, and it can be concerning. While some causes of the burning smell may be harmless, others can pose a serious threat to your health and safety. That's why it's essential to seek professional HVAC services if your heater smells burning when turning on your heat. In this blog post, we'll explore the 4 potential causes of a burning smell when you turn on your heat and discuss the importance of contacting an HVAC professional for help.

Burning Dust Smell

When you turn on the heat, one common issue is a burning dust smell. This odor often occurs when you turn on your heating system for the first time after a long period of inactivity. The smell usually goes away within a few minutes. The burning dust smell also occurs if there's a buildup of dust in your heating system, which can be a fire hazard.
To address this problem, an HVAC professional should inspect and clean your heating system. You can also replace your air filter to prevent dust buildup.

Old Furnace Filter/Dirty Vents

Another cause is an old furnace filter or dirty vents. Over time, your furnace filter can become clogged with dirt and debris, reducing airflow and causing the heating system to work harder. As a result, the furnace can overheat and emit a musty burning smell.
To address this issue, replace your furnace filter regularly, ideally every three months. Additionally, have your vents cleaned to remove any dirt or debris that may have accumulated.

Something Is in Your Heating System

If you suspect that there is an object in your heating system, it is crucial to contact a professional HVAC technician immediately. Attempting to remove the object yourself could be dangerous and cause more harm to your heating system. A skilled HVAC technician has the necessary tools and knowledge to remove the object safely and efficiently without causing further damage to your system.
Ignoring the problem leads to serious issues in the long run, such as increased energy bills and potential damage to your heater. Regular maintenance and inspections by a professional HVAC service can also help prevent such incidents from occurring in the first place, ensuring the safety and efficiency of your heating system. So, if you ever suspect something is in your heating system, don't hesitate to call a trusted HVAC service company like Home Alliance.

Electrical Issues

Finally, an electrical issue also causes a burning smell from the heater. This could be caused by anything from a faulty wire to a malfunctioning component, creating a distinct electrical burning smell.
If you suspect an electrical issue, turn off the heater immediately and contact an HVAC professional to inspect your heating system and identify the root cause of the issue.

Rotten Eggs Smell

A gas leak could be extremely dangerous and should not be taken lightly. The smell of rotten eggs clearly indicates a gas leak in your home. Mercaptan, a chemical added to natural gas, gives it an easily detectable strong odor. When you smell this distinct odor, it is important to take immediate action to prevent any potential harm.
First, turn off your heating system and any other gas appliances. Open all windows and doors to allow for ventilation and evacuate your home immediately. Do not use any electrical devices, including light switches or phones, as they create a spark that could ignite the gas. Contact your gas company or a professional HVAC technician to come and address the issue as soon as possible. Remember, safety always comes first when it comes to a potential gas leak.
