7 Common Mini-Split Issues and How to Resolve Them

July 12, 2021

Having mini-split installation done is a wise solution for solving comfort issues in your residence. 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 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 could be a problem with the condensate drain or drain line. It’s typical for a drain line to be clogged with mold, force water to back up and spill. Contact Ambient Air at 520-201-3871 for support and we’ll get your drain unclogged promptly.

2. Mini-Split is Making Noise

Mini-splits typically don’t generate much noise when they’re on. But there are a couple of situations where they could make 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 happen if your mini-split switches into defrost mode to keep itself from icing up.

You shouldn’t be alarmed if you hear these noises since they’re expected. However, if your mini-split keeps switching into defrost mode, it’s a hint that something is up, such as low refrigerant, a flawed circuit board or malfunctioning sensors. Your Ambient Air HVAC professional 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, icy coils could be the problem. Like we discussed before, iced-over coils might be the effect of low refrigerant, a bad circuit board or malfunctioning sensors. Reach us at 520-201-3871 for support.

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 needs refrigerant to shift heat and keep your residence pleasant. These leaks must be repaired by a licensed HVAC technician, so call us at 520-201-3871 for support.

5. Mini-Split is Not Dehumidifying

Like an air conditioner, a mini-split is effective at dehumidifying during the summer. However, this may be interrupted by mold in the condensate drain line. Another reason your mini-split air conditioner may not be dehumidifying very well is if it’s oversized. A system that’s too large will cool down a space too fast without having a chance 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 tell you that something is wrong. Here are five of the most usual 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 specialist like Ambient Air examine and clean the condensate drain and drain line, if needed.

Vinegar

If your mini-split smells like vinegar or has a sweet odor, you’re possibly dealing with a refrigerant leak. Another certain clue that you don’t have ample refrigerant is a low concentration of cool air. Reach us at 520-201-3871 for help.

Fish

If your mini-split smells like fish, a couple of things could be wrong. In some situations this smell means there is electrical trouble or that there’s a leak. Nevertheless, contact us at 520-201-3871 for assistance.

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, replacing the batteries will solve the problem. If you’re still experiencing trouble, call us at 520-201-3871.
