7 Common Mini-Split Problems and How to Repair Them

July 12, 2021

Having mini-split installation done is an excellent solution for solving comfort troubles in your house. These systems don’t have to have ductwork to give energy-efficient heating and cooling. Like any other home comfort system, they can run into issues from time to time. Here are seven of the most common mini-split problems 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 situation with the condensate drain or drain line. It’s common for a drain line to get clogged with mold, force water to back up and drip. Reach Taylor's Heating & Air Conditioning at 519-296-4437 for assistance and we’ll get your drain unblocked rapidly.

2. Mini-Split is Making Noise

Mini-splits usually don’t make much noise when they’re operating. But there are a few situations where they may 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 occur if your mini-split goes into defrost mode to keep itself from icing over.

You shouldn’t be worried if you hear these noises as 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 flawed circuit board or broken sensors. Your Taylor's Heating & Air Conditioning HVAC technician will be able to pinpoint 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, icy coils could be the problem. Like we talked about previously, iced-over coils can be the result of insufficient refrigerant, a failing circuit board or broken sensors. Reach us at 519-296-4437 for assistance.

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 transfer heat and keep your house pleasant. These leaks must be fixed by a licensed HVAC tech, so reach us at 519-296-4437 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 can be interrupted by clogs in the condensate drain line. Another reason your mini-split air conditioner may not be dehumidifying very efficientlyis if it’s too big. A system that’s too big will cool down a room too rapidly 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 grab your attention 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 might have a mold issue. Have a specialist like Taylor's Heating & Air Conditioning examine 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 experiencing a refrigerant leak. Another surefire clue that you don’t have ample refrigerant is a lack of chilled air. Reach us at 519-296-4437 for support.

Fish

If your mini-split smells like fish, a couple of things could be wrong. In some instances this smell means there is electrical trouble or that there’s a leak. Nevertheless, reach us at 519-296-4437 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 dead, your mini-split won’t switch on. In many instances, replacing the batteries will solve the situation. If you’re still having trouble, contact us at 519-296-4437.
