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 problems in your house. These systems don’t have to have ductwork to deliver energy-efficient heating and cooling. Like any other home comfort system, they can run into problems from time to time. Here are seven of the most common mini-split problems 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 an issue with the condensate drain or drain line. It’s typical for a drain line to get clogged with mold, force water to back up and leak. Call Ocean Air Conditioning and Heating at 949-525-9119 for help and we’ll get your drain unclogged quickly.

2. Mini-Split is Making Noise

Mini-splits typically don’t make much noise when they’re on. But there are a few situations where they could produce sounds.

  • Popping or clicking: This can be the result of the plastic housing expanding or contracting while the system is operating.
  • Swooshing, crackling or gurgling: This can happen if your mini-split turns on defrost mode to prevent itself from icing over.

You shouldn’t be alarmed if you hear these noises as they’re expected. However, if your mini-split keeps switching into defrost mode, it’s a clue that something is wrong, such as insufficient refrigerant, a flawed circuit board or broken sensors. Your Ocean Air Conditioning and Heating HVAC pro will be able to find and solve the problem quickly.

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

If your mini-split is not heating or blowing hot air, icy coils could be the problem. Like we mentioned prior to this, iced-over coils could be the consequence of insufficient refrigerant, a failing circuit board or broken sensors. Contact us at 949-525-9119 for support.

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 uses refrigerant to move heat and keep your residence comfortable. These leaks must be fixed by a licensed HVAC technician, so reach us at 949-525-9119 for assistance.

5. Mini-Split is Not Dehumidifying

Similar to an air conditioner, a mini-split is effective at dehumidifying during the summer. However, this can be halted by mold in the condensate drain line. Another reason your mini-split air conditioner may not be dehumidifying very effectivelyis if it’s too big. A system that’s oversized will cool down an area too rapidly without having a moment to dehumidify it. Mini-split size is based 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 typical smells and what they mean.

Musty, Sour or Mildew

If your mini-split smells musty, sour or like mildew, you could have a mold issue. Have a specialist like Ocean Air Conditioning and Heating check and flush the condensate drain and drain line, if required.

Vinegar

If your mini-split smells like vinegar or has a sweet odor, you’re probably encountering a refrigerant leak. Another certain hint that you don’t have sufficient refrigerant is a weak flow of cold air. Reach us at 949-525-9119 for assistance.

Fish

If your mini-split smells like fish, the following things things could be wrong. Sometimes this smell means there is electrical trouble or that there’s a leak. Nevertheless, call us at 949-525-9119 for help.

7. Mini-Split Will Not Power On

If your mini-split will not power on, check the remote first. If the batteries are bad, your mini-split won’t turn on. In the majority of instances, replacing the batteries will solve the problem. If you’re still experiencing trouble, reach us at 949-525-9119.
