Troubleshooting Foul Odors in Your Ductless AC

If you have a ductless mini split system, keeping it clean is crucial to maintaining good operation. If your ductless unit isn’t clean, it may begin to produce bad odors as a result. You can keep reading to learn more about some of the bad odors that might come from your ductless mini split and what they mean. 

Then give our team a call for your Covington AC repair. After we address any bad odors in your ductless mini split, we can give you feedback on how to prevent bad smells from happening again in the future.

Musty or Damp Odors

A ductless mini split is the smaller and more compact version of a large central air conditioner. It works in essentially the same way, although all of the components are much smaller. Because of this, it’s easier for problems to worsen quickly. If your ductless mini split is producing a musty or damp odor, it’s likely due to problems with the condensate drain line.

Since the drain line is small, it is more prone to developing clogs if dust builds up in a line or mold starts to grow. You can clean the drain line and associated drip pan yourself using cloths and a wet/dry vacuum. After getting rid of a clog, you can also rinse the line out monthly with vinegar to prevent clogs from developing in the first place. 

Burning Odors

If it smells like something is burning inside your ductless unit, it’s likely that the system is overheating. Something is wrong inside the unit, and as a result, it is working harder to try and produce cooled or heated air based on your settings. 

It’s possible the wiring is damaged, or the motor is failing. Either way, you need to turn the unit off completely as soon as you detect a burning odor to prevent additional damage. Then, call us so we can troubleshoot and fix the problem promptly. 

The Smell of Rotten Eggs

If you smell rotten eggs, this isn’t necessarily a problem with your ductless mini split. However, your ductless mini split may be drawing in the air and blowing it back out, making it seem like the odor originates from your ductless HVAC. 

A rotten egg smell almost always points to a gas leak somewhere within the lines of your home. Although natural gas does not have an odor, many gas service providers do add a bad smell so that it’s easier for you to identify a leak when it happens. And if your home suddenly smells like rotten eggs, you need to call for a check-up on your gas lines.

Chemical Odors

If your ductless mini split begins to produce a chemical-like odor, there may be a refrigerant leak. Refrigerant can produce a chemical smell, although sometimes it can also smell slightly sweet. Refrigerant leaks are very serious and need to be addressed right away. 

Refrigerant is perfectly safe as long as it stays contained within the refrigerant lines of your ductless mini split. However, once it begins to leak out, it can damage the system as well as posing hazards for your family. If you suspect a refrigerant leak, leave your unit alone until our team can check it out. Touching the chemical or breathing in the fumes from refrigerant is dangerous.
