7 Common Mini-Split Problems and How to Resolve Them

July 12, 2021

Having mini-split installation done is a good way to solve comfort difficulties in your home. These systems don’t have to have ductwork to deliver energy-efficient heating and cooling. Much like any other home comfort system, they can experience issues occasionally. Here are seven of the most frequent mini-split troubles 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 could be an issue with the condensate drain or drain line. It’s typical for a drain line to get clogged with mold, force water to back up and leak. Contact West Jefferson Plumbing and Heating, Inc. at 614-450-1575 for support and we’ll get your drain unplugged rapidly.

2. Mini-Split is Making Noise

Mini-splits usually don’t generate much noise when they’re running. But there are a few times where they might 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 switches into defrost mode to keep itself from icing up.

You shouldn’t be alarmed if you hear these noises since they’re typical. However, if your mini-split keeps turning on defrost mode, it’s a hint that something is wrong, including not enough refrigerant, a bad circuit board or broken sensors. Your West Jefferson Plumbing and Heating, Inc. HVAC pro will be able to pinpoint and resolve the situation quickly.

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

If your mini-split is not heating or blowing hot air, frozen coils might be the problem. Like we talked about prior to this, icy coils could be the consequence of insufficient refrigerant, a faulty circuit board or broken sensors. Contact us at 614-450-1575 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 needs refrigerant to move heat and keep your house cool. These leaks must be fixed by a licensed HVAC technician, so reach us at 614-450-1575 for assistance.

5. Mini-Split is Not Dehumidifying

Like an air conditioner, a mini-split is efficient at dehumidifying during the summer. However, this might be interrupted by mold 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 rapidly without having time 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 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 West Jefferson Plumbing and Heating, Inc. examine and flush the condensate drain and drain line, if needed.

Vinegar

If your mini-split smells like vinegar or has a sweet odor, you’re probably experiencing a refrigerant leak. Another sure clue that you don’t have sufficient refrigerant is a lack of chilled air. Reach us at 614-450-1575 for support.

Fish

If your mini-split smells like fish, a couple of things could be wrong. Sometimes this smell means there is electrical trouble or that there’s a leak. Regardless, call us at 614-450-1575 for help.

7. Mini-Split Will Not Power On

If your mini-split will not power on, check the remote first. If the batteries are out of juice, your mini-split won’t turn on. In the majority of instances, replacing the batteries will solve the issue. If you’re still having trouble, reach us at 614-450-1575.
