What Could Odd Smells From Your Central Air Conditioning Mean?

An air conditioner has numerous ways to communicate with the owners, like sounds, initial problem signs, and smells. In this article, we shall focus on the parts that can face damage and give off odd smells while the air conditioner is working or resting.

Owners should try to detect these smells soon so they can contact an AC company in Wesley Chapel for repair services. Most smells indicate severe issues with the systems.

Pay Extra Attention to These Parts When They Smell Unusual Smells:

  • Blockages in the Drain Line

The drain line of your air conditioner carries water, one of the by-products when your air conditioner works, to the outside of your home. If there are cloggings in the drain line, the water will not leave outside and give way to bacterial growth, which gives off a foul smell.

  • An Overheating Central Motor

The central motor of your air conditioner works with the central fan to circulate cool air throughout the house. If the motor overheats or malfunctions due to excessive working or other external damage, you may have a burning smell lingering in your home.

  • Short Circuits in the Central Panel

Short circuits in an air conditioner are common if the system is old or does not receive regular professional care. A smell that resembles gunpowder indicates a short circuit or more in the central panel or motors.

  • Dead Insects in The System

During the winter season, insects and small animals may take shelter in the outside unit of your system that may die when the summer season arrives. If your air conditioner gives off a rotting smell, you should check the outside unit and ducts for dead animals.

  • Blockages in the Sewer Line

You can detect sewer lines’ smell easily, as they smell the worst. If your home smells extremely foul, it may indicate the sewer line is facing blockages. You can try to remove the blockages yourself or can contact a professional for help.

  • Dirty Evaporator Coils

If your home smells of burning dust, check the evaporator coils. These coils carry refrigerant that releases heat while working, and the dust settled on the coils may burn due to the high temperature, giving off a burning smell in your home.

  • Smoking

Smoking is not safe for your body and your air conditioner. The smoke stays indoors, trapped in the walls, and later enters your air conditioner. The particles in that smoke can severely damage your air conditioner to the extent you may have to contact a technician for repairs to air conditioning in Wesley Chapel, FL.

  • Refrigerant Leakages

An alcoholic smell may be due to refrigerant leakages in your home. Refrigerant smells like acetone, which closely resembles the smell of alcohol. If you hear a hissing or a bubbling sound along with the alcoholic smell, it is a sure indicator that your refrigerant is leaking and needs a refill.
