7 Common Mini-Split Problems and How to Fix Them

July 12, 2021

Having mini-split installation done is a great solution for solving comfort troubles in your home. These systems don’t need ductwork to provide energy-efficient heating and cooling. Similar to any other home comfort system, they can run into troubles from time to time. Here are seven of the most common mini-split issues and how you can repair 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 an issue 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 spill. Contact Aggressive Mechanical at 732-806-5536 for help and we’ll get your drain unclogged rapidly.

2. Mini-Split is Making Noise

Mini-splits normally don’t generate much noise when they’re operating. But there are a couple of times where they might create sounds.

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

You shouldn’t be troubled if you hear these noises since they’re normal. However, if your mini-split keeps going into defrost mode, it’s a symptom that something is wrong, including insufficient refrigerant, a faulty circuit board or malfunctioning sensors. Your Aggressive Mechanical HVAC technician will be able to pinpoint and resolve the situation fast.

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 issue. Like we mentioned prior to this, icy coils can be the effect of low refrigerant, a faulty circuit board or broken sensors. Call us at 732-806-5536 for help.

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

If your mini-split is not cooling or blowing cold air, there might be a refrigerant leak. Your mini-split AC needs refrigerant to shift heat and keep your house cold. These leaks must be repaired by a licensed HVAC pro, so call us at 732-806-5536 for support.

5. Mini-Split is Not Dehumidifying

Much like an air conditioner, a mini-split is efficient at dehumidifying during the summer. However, this can be stopped 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 big will cool down a space too rapidly without having a moment to dehumidify it. Mini-split size is planned on square footage and BTUs.

6. Mini-Split Smells

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

Musty, Sour or Mildew

If your mini-split smells musty, sour or like mildew, you might have a mold issue. Have a professional like Aggressive Mechanical inspect and rinse the condensate drain and drain line, if necessary.

Vinegar

If your mini-split smells like vinegar or has a sweet odor, you’re possibly experiencing a refrigerant leak. Another sure clue that you don’t have sufficient refrigerant is a weak flow of cold air. Reach us at 732-806-5536 for help.

Fish

If your mini-split smells like fish, a couple of things could be wrong. Sometimes this smell means there are electrical issues or that there’s a leak. Nevertheless, reach us at 732-806-5536 for assistance.

7. Mini-Split Will Not Power On

If your mini-split will not power on, examine the remote first. If the batteries are bad, your mini-split won’t run. In most experiences, putting in new batteries will solve the situation. If you’re still having trouble, reach us at 732-806-5536.
