7 Common Mini-Split Issues and How to Fix Them

July 12, 2021

Having mini-split installation done is a smart way to solve comfort issues in your home. These systems don’t require ductwork to deliver energy-efficient heating and cooling. Much like any other home comfort system, they can experience problems sometimes. Here are seven of the most typical mini-split problems and how you can resolve them.

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

If your mini-split is dripping water or not draining water, there may be a situation 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. Call Air Commander's Heating & Air Conditioning Co. at 863-216-2923 for support and we’ll get your drain unplugged promptly.

2. Mini-Split is Making Noise

Mini-splits normally don’t create a lot of noise when they’re operating. But there are two instances where they may produce sounds.

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

You shouldn’t be worried if you hear these noises because they’re typical. However, if your mini-split keeps switching into defrost mode, it’s a clue that something is off, including insufficient refrigerant, a flawed circuit board or malfunctioning sensors. Your Air Commander's Heating & Air Conditioning Co. HVAC professional will be able to find and correct the situation fast.

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 the issue. Like we mentioned prior to this, frozen coils may be the result of insufficient refrigerant, a bad circuit board or defective sensors. Call us at 863-216-2923 for support.

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

If your mini-split is not cooling or blowing cold air, there could be a refrigerant leak. Your mini-split AC relies on refrigerant to move heat and keep your residence cool. These leaks must be fixed by a licensed HVAC technician, so contact us at 863-216-2923 for assistance.

5. Mini-Split is Not Dehumidifying

Much like an air conditioner, a mini-split is efficient at dehumidifying during the summer. However, this could be stopped by clogs in the condensate drain line. Another reason your mini-split air conditioner may not be dehumidifying properlyis if it’s oversized. A system that’s too large will cool down a room too quickly without having time 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 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 could have a mold issue. Have a pro like Air Commander's Heating & Air Conditioning Co. examine and clean the condensate drain and drain line, if required.

Vinegar

If your mini-split smells like vinegar or has a sweet odor, you’re possibly encountering a refrigerant leak. Another surefire sign that you don’t have ample refrigerant is a weak flow of cold air. Contact us at 863-216-2923 for support.

Fish

If your mini-split smells like fish, a couple of things could be wrong. In some instances this smell means there are electrical issues or that there’s a leak. Nevertheless, reach us at 863-216-2923 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 bad, your mini-split won’t turn on. In the majority of situations, putting in fresh batteries will fix the situation. If you’re still experiencing trouble, call us at 863-216-2923.
