My New Furnace Smells. Is This Normal?

An efficient furnace will help ensure your family stays comfortable during the colder months. Regular maintenance is essential to keep your equipment in top shape. If you notice unfamiliar smells coming from the unit, contact a reputable heating and AC repair company immediately. 

Here are common reasons furnaces emit weird odors. 

Common Furnace Smells

Burning Plastic or Wires

The smell of burning plastic or wire isn’t something you should take lightly. It often indicates there is an electrical problem with your unit. You want to address it immediately because it could endanger your household. There could be an overheating motor or shorted wires in the unit’s components. 

Musty Smell 

Mold growth in the ductwork often causes HVAC systems to produce musty odors. You can avoid this issue by ensuring proper airflow around your furnace. There should be nothing obstructing vents. Another thing that helps is regular air filter replacements. 

Rotten Egg Smell 

A rotten egg smell usually comes from furnaces that run on propane gas or oil. It occurs when the natural gas inside the unit produces sulfur dioxide. This problem typically means issues with the vent pipe connection between the equipment and other components like exhaust draft inducer fans, burners, flue lining, flame sensors, etc. 

For your safety, leave furnace repairs to experienced professionals. They will assess your equipment thoroughly to determine what exactly it needs. They can also give you a quote for your AC repair cost. 

Steps to Take to Address the Issue

Identifying the source of the odor is the first step you need to take to eliminate it. A skilled professional can do the job for you and ensure the problem doesn’t recur. They can determine if your unit requires repair, maintenance or replacement.
