7 Common Mini-Split Problems and How to Fix Them

July 12, 2021

Having mini-split installation done is a good way to solve comfort difficulties in your home. These systems don’t require ductwork to deliver energy-efficient heating and cooling. Like any other home comfort system, they can run into problems sometimes. 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 may be a problem with the condensate drain or drain line. It’s expected for a drain line to become clogged with mold, force water to back up and leak. Contact SchagrinGAS Company at 302-231-1380 for assistance and we’ll get your drain unclogged promptly.

2. Mini-Split is Making Noise

Mini-splits typically don’t generate much noise when they’re on. But there are a few instances where they might create sounds.

  • Popping or clicking: This can be due to 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 prevent itself from freezing over.

You shouldn’t be worried if you hear these noises since they’re normal. However, if your mini-split keeps switching into defrost mode, it’s a clue that something is up, including insufficient refrigerant, a faulty circuit board or malfunctioning sensors. Your SchagrinGAS Company HVAC technician will be able to locate and correct the problem quickly.

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 may be the issue. Like we mentioned previously, frozen coils could be the effect of low refrigerant, a faulty circuit board or defective sensors. Reach us at 302-231-1380 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 house cold. These leaks must be repaired by a licensed HVAC tech, so reach us at 302-231-1380 for help.

5. Mini-Split is Not Dehumidifying

Much like an air conditioner, a mini-split does a great job at dehumidifying during the summer. However, this might be interrupted by blockages in the condensate drain line. Another reason your mini-split air conditioner may not be dehumidifying properlyis if it’s too large. 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 tell you 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 specialist like SchagrinGAS Company inspect and clean the condensate drain and drain line, if required.

Vinegar

If your mini-split smells like vinegar or has a sweet odor, you’re probably dealing with a refrigerant leak. Another certain hint that you don’t have ample refrigerant is a lack of cool air. Contact us at 302-231-1380 for support.

Fish

If your mini-split smells like fish, a few things could be wrong. Sometimes this smell means there are electrical issues or that there’s a leak. Regardless, reach us at 302-231-1380 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 out of juice, your mini-split won’t switch on. In the majority of instances, putting in fresh batteries will fix the situation. If you’re still experiencing trouble, call us at 302-231-1380.
