7 Common Mini-Split Troubles and How to Resolve Them

July 12, 2021

Having mini-split installation done is a smart approach to solve comfort troubles in your home. These systems don’t require ductwork to provide energy-efficient heating and cooling. Similar to any other home comfort system, they can run into troubles sometimes. Here are seven of the most common mini-split troubles 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 may be an issue 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 spill. Reach HCE Systems Inc at 276-302-0076 for help and we’ll get your drain unclogged rapidly.

2. Mini-Split is Making Noise

Mini-splits normally don’t generate much noise when they’re on. But there are two instances where they may produce sounds.

  • Popping or clicking: This can be due to the plastic housing expanding or contracting while the system is on.
  • Swooshing, crackling or gurgling: This can happen if your mini-split turns on defrost mode to prevent itself from freezing over.

You shouldn’t be alarmed if you hear these noises as they’re typical. However, if your mini-split keeps switching into defrost mode, it’s a symptom that something is wrong, including low refrigerant, a faulty circuit board or broken sensors. Your HCE Systems Inc HVAC tech will be able to locate and correct the issue 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 issue. Like we discussed prior to this, frozen coils could be the effect of insufficient refrigerant, a failing circuit board or defective sensors. Call us at 276-302-0076 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 uses refrigerant to move heat and keep your home comfortable. These leaks must be fixed by a licensed HVAC professional, so contact us at 276-302-0076 for help.

5. Mini-Split is Not Dehumidifying

Like an air conditioner, a mini-split does a great job at dehumidifying during the summer. However, this can be interrupted by mold 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 calculated on square footage and BTUs.

6. Mini-Split Smells

If your ductless mini-split smells, it’s trying to get 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 professional like HCE Systems Inc examine 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 encountering a refrigerant leak. Another sure clue that you don’t have ample refrigerant is a weak flow of cool air. Call us at 276-302-0076 for help.

Fish

If your mini-split smells like fish, a couple of things could be wrong. In some instances this smell means there is an electrical problem or that there’s a leak. Regardless, contact us at 276-302-0076 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 bad, your mini-split won’t run. In many experiences, putting in fresh batteries will resolve the situation. If you’re still having trouble, reach us at 276-302-0076.
