7 Common Mini-Split Problems and How to Fix Them

July 12, 2021

Having mini-split installation done is a wise solution for solving comfort issues in your residence. These systems don’t have to have ductwork to deliver energy-efficient heating and cooling. Much like any other home comfort system, they can have issues occasionally. 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 a problem with the condensate drain or drain line. It’s expected for a drain line to get clogged with mold, force water to back up and drip. Call Eco Fresh HVAC Inc. at 714-855-1717 for assistance and we’ll get your drain unplugged rapidly.

2. Mini-Split is Making Noise

Mini-splits usually don’t make much noise when they’re running. But there are a couple of instances where they could make sounds.

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

You shouldn’t be alarmed if you hear these noises because they’re normal. However, if your mini-split keeps going into defrost mode, it’s a hint that something is up, including not enough refrigerant, a flawed circuit board or malfunctioning sensors. Your Eco Fresh HVAC Inc. HVAC technician will be able to locate 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, icy coils might be to blame. Like we mentioned prior to this, icy coils may be the consequence of insufficient refrigerant, a faulty circuit board or defective sensors. Reach us at 714-855-1717 for assistance.

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 transfer heat and keep your residence comfortable. These leaks must be repaired by a licensed HVAC technician, so call us at 714-855-1717 for help.

5. Mini-Split is Not Dehumidifying

Like 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 efficientlyis if it’s too big. A system that’s oversized will cool down a space 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 grab 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 may have a mold issue. Have a professional like Eco Fresh HVAC Inc. inspect and rinse the condensate drain and drain line, if needed.

Vinegar

If your mini-split smells like vinegar or has a sweet odor, you’re probably dealing with a refrigerant leak. Another certain clue that you don’t have ample refrigerant is a lack of cool air. Call us at 714-855-1717 for help.

Fish

If your mini-split smells like fish, a few things could be wrong. In some instances this smell means there is an electrical problem or that there’s a leak. Either way, contact us at 714-855-1717 for help.

7. Mini-Split Will Not Power On

If your mini-split will not power on, look at the remote first. If the batteries are out of juice, your mini-split won’t run. In the majority of experiences, putting in new batteries will fix the trouble. If you’re still running into trouble, reach us at 714-855-1717.
