7 Common Mini-Split Problems and How to Fix Them

July 12, 2021

Having mini-split installation done is a wise approach to solve comfort troubles in your house. These systems don’t require ductwork to provide energy-efficient heating and cooling. Like any other home comfort system, they can run into troubles sometimes. Here are seven of the most common mini-split issues and how you can solve them.

1. Mini-Split is Dripping Water or Not Draining Water

If your mini-split is dripping water or not draining water, there might be a problem with the condensate drain or drain line. It’s expected for a drain line to be clogged with mold, force water to back up and drip. Contact PWA Heating & Cooling Inc at 815-410-1231 for support and we’ll get your drain unclogged promptly.

2. Mini-Split is Making Noise

Mini-splits usually don’t generate much noise when they’re running. But there are a few times where they might make sounds.

  • Popping or clicking: This can be due to the plastic housing expanding or contracting while the system is running.
  • Swooshing, crackling or gurgling: This can take place if your mini-split turns on defrost mode to stop itself from icing over.

You shouldn’t be troubled if you hear these noises as they’re expected. However, if your mini-split keeps going into defrost mode, it’s a hint that something is up, such as insufficient refrigerant, a bad circuit board or defective sensors. Your PWA Heating & Cooling Inc HVAC tech will be able to find and solve the situation quickly.

3. Mini-Split is Not Heating or Blowing Hot Air

If your mini-split is not heating or blowing hot air, frozen coils may be the problem. Like we mentioned before, iced-over coils can be the result of low refrigerant, a faulty circuit board or malfunctioning sensors. Call us at 815-410-1231 for assistance.

4. Mini-Split is Not Cooling or Blowing Cold Air

If your mini-split is not cooling or blowing cold air, there may be a refrigerant leak. Your mini-split AC uses refrigerant to shift heat and keep your residence cold. These leaks must be repaired by a licensed HVAC tech, so call us at 815-410-1231 for help.

5. Mini-Split is Not Dehumidifying

Like an air conditioner, a mini-split does a great job at dehumidifying during the summer. However, this might be halted by mold in the condensate drain line. Another reason your mini-split air conditioner may not be dehumidifying very efficientlyis if it’s too big. A system that’s too large will cool down a space too rapidly without having a chance to dehumidify it. Mini-split size is calculated on square footage and BTUs.

6. Mini-Split Smells

If your ductless mini-split smells, it’s trying to get your attention that something is wrong. Here are five of the most common smells and what they mean.

Musty, Sour or Mildew

If your mini-split smells musty, sour or like mildew, you likely have a mold issue. Have a pro like PWA Heating & Cooling Inc inspect and flush the condensate drain and drain line, if necessary.

Vinegar

If your mini-split smells like vinegar or has a sweet odor, you’re possibly encountering a refrigerant leak. Another certain clue that you don’t have ample refrigerant is a weak flow of cold air. Contact us at 815-410-1231 for help.

Fish

If your mini-split smells like fish, the following things things could be wrong. In some situations this smell means there are electrical issues or that there’s a leak. Regardless, call us at 815-410-1231 for support.

7. Mini-Split Will Not Power On

If your mini-split will not power on, look at the remote first. If the batteries are dead, your mini-split won’t run. In the majority of situations, replacing the batteries will resolve the trouble. If you’re still experiencing trouble, contact us at 815-410-1231.
