7 Common Mini-Split Issues and How to Resolve Them

July 12, 2021

Having mini-split installation done is an excellent approach 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 have issues occasionally. Here are seven of the most frequent mini-split troubles and how you can repair 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 spill. Call Tokay Heating and Air Conditioning at 209-257-3156 for assistance and we’ll get your drain unclogged rapidly.

2. Mini-Split is Making Noise

Mini-splits typically don’t make much noise when they’re on. But there are a couple of situations where they could 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 occur if your mini-split turns on defrost mode to stop itself from icing over.

You shouldn’t be worried if you hear these noises as they’re expected. However, if your mini-split keeps switching into defrost mode, it’s a symptom that something is off, like low refrigerant, a faulty circuit board or malfunctioning sensors. Your Tokay Heating and Air Conditioning HVAC technician will be able to find and correct the situation fast.

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 might be to blame. Like we discussed prior to this, icy coils might be the effect of insufficient refrigerant, a bad circuit board or defective sensors. Contact us at 209-257-3156 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 home cold. These leaks must be resolved by a licensed HVAC technician, so reach us at 209-257-3156 for support.

5. Mini-Split is Not Dehumidifying

Much like an air conditioner, a mini-split is effective at dehumidifying during the summer. However, this may be interrupted by blockages 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 big will cool down a space too rapidly without having time 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 likely have a mold issue. Have a pro like Tokay Heating and Air Conditioning check and clean the condensate drain and drain line, if necessary.

Vinegar

If your mini-split smells like vinegar or has a sweet odor, you’re possibly experiencing a refrigerant leak. Another sure clue that you don’t have ample refrigerant is a weak flow of cool air. Call us at 209-257-3156 for support.

Fish

If your mini-split smells like fish, the following things things could be wrong. In some instances this smell means there are electrical issues or that there’s a leak. Either way, call us at 209-257-3156 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 dead, your mini-split won’t switch on. In the majority of experiences, putting in fresh batteries will solve the trouble. If you’re still running into trouble, call us at 209-257-3156.
