7 Common Mini-Split Troubles and How to Fix Them

July 12, 2021

Having mini-split installation done is a smart way to solve comfort troubles in your house. These systems don’t require ductwork to give energy-efficient heating and cooling. Much like any other home comfort system, they can experience problems occasionally. Here are seven of the most typical mini-split issues 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 expected for a drain line to get clogged with mold, force water to back up and spill. Reach Knoechel Heating Company at 724-425-5852 for assistance and we’ll get your drain unclogged promptly.

2. Mini-Split is Making Noise

Mini-splits typically don’t create a lot of noise when they’re operating. But there are a couple of times where they may produce sounds.

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

You shouldn’t be troubled 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, like low refrigerant, a flawed circuit board or broken sensors. Your Knoechel Heating Company HVAC tech will be able to locate and solve the situation rapidly.

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

If your mini-split is not heating or blowing hot air, frozen coils could be the problem. Like we discussed before, frozen coils can be the result of insufficient refrigerant, a bad circuit board or broken sensors. Contact us at 724-425-5852 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 transfer heat and keep your residence cool. These leaks must be repaired by a licensed HVAC tech, so contact us at 724-425-5852 for help.

5. Mini-Split is Not Dehumidifying

Like an air conditioner, a mini-split is effective at dehumidifying during the summer. However, this might be interrupted by clogs in the condensate drain line. Another reason your mini-split air conditioner may not be dehumidifying very effectivelyis if it’s oversized. A system that’s oversized will cool down a room too rapidly 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 grab 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 Knoechel Heating Company check and flush 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 weak flow of cool air. Reach us at 724-425-5852 for help.

Fish

If your mini-split smells like fish, a few things could be wrong. In some instances this smell means there is electrical trouble or that there’s a leak. Regardless, contact us at 724-425-5852 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 dead, your mini-split won’t run. In most situations, putting in new batteries will solve the problem. If you’re still having trouble, reach us at 724-425-5852.
