7 Common Mini-Split Issues and How to Resolve Them

July 12, 2021

Having mini-split installation done is an excellent solution for solving comfort problems in your residence. These systems don’t require ductwork to provide energy-efficient heating and cooling. Much like any other home comfort system, they can run into problems occasionally. Here are seven of the most common mini-split problems and how you can fix 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 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 leak. Contact Wallpe Heating & Cooling at 812-663-7252 for support and we’ll get your drain unplugged promptly.

2. Mini-Split is Making Noise

Mini-splits usually don’t generate much noise when they’re on. But there are two instances where they might make sounds.

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

You shouldn’t be alarmed if you hear these noises because they’re typical. However, if your mini-split keeps turning on defrost mode, it’s a hint that something is off, including insufficient refrigerant, a bad circuit board or broken sensors. Your Wallpe Heating & Cooling HVAC pro will be able to pinpoint and correct 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 the issue. Like we talked about previously, icy coils could be the result of low refrigerant, a failing circuit board or defective sensors. Contact us at 812-663-7252 for help.

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 house cool. These leaks must be fixed by a licensed HVAC professional, so reach us at 812-663-7252 for assistance.

5. Mini-Split is Not Dehumidifying

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 big will cool down a room too rapidly without having a moment to dehumidify it. Mini-split size is calculated 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 professional like Wallpe Heating & Cooling check 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 likely experiencing a refrigerant leak. Another sure hint that you don’t have ample refrigerant is a lack of chilled air. Contact us at 812-663-7252 for assistance.

Fish

If your mini-split smells like fish, a few things could be wrong. In some situations this smell means there is an electrical problem or that there’s a leak. Nevertheless, contact us at 812-663-7252 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 most experiences, replacing the batteries will solve the trouble. If you’re still having trouble, reach us at 812-663-7252.
