7 Common Mini-Split Problems and How to Fix Them

July 12, 2021

Having mini-split installation done is a good approach to solve comfort troubles in your home. These systems don’t have to have ductwork to provide energy-efficient heating and cooling. Like any other home comfort system, they can have troubles occasionally. Here are seven of the most common 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 might be an issue with the condensate drain or drain line. It’s common for a drain line to become clogged with mold, force water to back up and spill. Contact West Michigan Heating & Air Conditioning Services at (616) 669-3961 for assistance and we’ll get your drain unblocked rapidly.

2. Mini-Split is Making Noise

Mini-splits normally don’t make much noise when they’re running. But there are a few times where they may create 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 take place if your mini-split switches into defrost mode to keep itself from icing up.

You shouldn’t be worried if you hear these noises since they’re typical. However, if your mini-split keeps turning on defrost mode, it’s a clue that something is wrong, including not enough refrigerant, a faulty circuit board or broken sensors. Your West Michigan Heating & Air Conditioning Services HVAC professional will be able to locate and resolve the issue rapidly.

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 mentioned prior to this, frozen coils might be the result of insufficient refrigerant, a bad circuit board or malfunctioning sensors. Reach us at (616) 669-3961 for assistance.

4. Mini-Split is Not Cooling or Blowing Cold Air

If your mini-split is not cooling or blowing cold air, there might be a refrigerant leak. Your mini-split AC relies on refrigerant to transfer heat and keep your residence cool. These leaks must be repaired by a licensed HVAC tech, so call us at (616) 669-3961 for support.

5. Mini-Split is Not Dehumidifying

Like an air conditioner, a mini-split is effective at dehumidifying during the summer. However, this might be stopped by mold in the condensate drain line. Another reason your mini-split air conditioner may not be dehumidifying properlyis if it’s too big. A system that’s too large will cool down an area 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 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 may have a mold issue. Have a professional like West Michigan Heating & Air Conditioning Services inspect 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 possibly dealing with a refrigerant leak. Another sure clue that you don’t have ample refrigerant is a low concentration of chilled air. Contact us at (616) 669-3961 for support.

Fish

If your mini-split smells like fish, the following things things could be wrong. In some situations this smell means there is an electrical problem or that there’s a leak. Either way, contact us at (616) 669-3961 for support.

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, putting in fresh batteries will solve the issue. If you’re still having trouble, call us at (616) 669-3961.
