Is there a funny smell when you turn on the AC? Most homeowners know that when their air conditioner is on the fritz, they need to call in the professionals for residential AC repair services. However, some smells indicate a bigger problem than just a blown fuse or loose wire. If you notice any of the following smells coming from your air conditioner, it's time to call in the experts.

1. Burning Rubber

If you smell something similar to burning rubber from your AC unit, it's likely due to an electrical malfunction. The burning rubber smell comes from the burning plastic covers. This is an extremely dangerous situation that a professional residential AC repair technician should handle. Do not attempt to repair the issue yourself because you could be putting yourself at risk of electrocution.

2. Sweet Smell

A sweet smell from your AC unit often indicates a Freon leak. While this isn't necessarily dangerous, it does mean that your AC unit isn't functioning properly and will need to be repaired. The technician will trace where the coils are leaking and apply a sealant before refilling the refrigerant.

3. Musty Smell

A musty or moldy smell coming from your AC unit typically indicates that there is mold or mildew present in the system. This is a health hazard, and It's important to resolve the issue as soon as possible by calling in a professional for residential AC repair services. They will wash off the mold with an antiseptic.

4. Chemical Smell

If you notice a chemical smell coming from your AC unit, it's likely due to a cleaning solution or other chemicals used to clean the unit. These chemicals can be harmful if inhaled, so it's important to have the issue resolved by a professional who will safely and effectively clean your AC unit without causing any harm.

5. Rotten Smell

It's not uncommon for small animals to get trapped in the AC's components. Lizards, mice, and even birds commonly find their way into the AC's ductwork. If you notice a rotten smell, it's likely an animal that has died inside the unit. You'll need a technician to remove the carcass and clean the AC unit safely

If you notice any strange smells coming from your air conditioner, don't ignore them! These smells could indicate a bigger problem than just a blown fuse or loose wire, so it's important to have a professional take a look.
