7 Common Mini-Split Issues and How to Resolve Them

July 12, 2021

Having mini-split installation done is a smart approach to solve comfort troubles in your residence. These systems don’t have to have ductwork to give energy-efficient heating and cooling. Like any other home comfort system, they can have troubles sometimes. Here are seven of the most frequent mini-split issues 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 could be a situation with the condensate drain or drain line. It’s expected for a drain line to become clogged with mold, force water to back up and leak. Call Airmen HVAC Service at 570-322-3131 for support and we’ll get your drain unplugged rapidly.

2. Mini-Split is Making Noise

Mini-splits normally don’t make much noise when they’re on. But there are a couple of situations where they could 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 turns on defrost mode to stop itself from icing up.

You shouldn’t be troubled if you hear these noises because they’re expected. However, if your mini-split keeps going into defrost mode, it’s a hint that something is up, including insufficient refrigerant, a flawed circuit board or broken sensors. Your Airmen HVAC Service HVAC tech will be able to find and correct the problem quickly.

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

If your mini-split is not heating or blowing hot air, ice on the coils may be to blame. Like we talked about before, icy coils may be the consequence of not enough refrigerant, a failing circuit board or broken sensors. Contact us at 570-322-3131 for assistance.

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 uses refrigerant to transfer heat and keep your residence pleasant. These leaks must be resolved by a licensed HVAC pro, so reach us at 570-322-3131 for assistance.

5. Mini-Split is Not Dehumidifying

Similar to an air conditioner, a mini-split is efficient at dehumidifying during the summer. However, this may 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 a moment 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 may have a mold issue. Have a specialist like Airmen HVAC Service 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 probably encountering a refrigerant leak. Another sure clue that you don’t have sufficient refrigerant is a lack of chilled air. Contact us at 570-322-3131 for assistance.

Fish

If your mini-split smells like fish, the following things things could be wrong. Sometimes this smell means there are electrical issues or that there’s a leak. Regardless, call us at 570-322-3131 for assistance.

7. Mini-Split Will Not Power On

If your mini-split will not power on, examine the remote first. If the batteries are out of juice, your mini-split won’t run. In many instances, putting in new batteries will fix the trouble. If you’re still running into trouble, contact us at 570-322-3131.
