7 Common Mini-Split Problems and How to Repair Them

July 12, 2021

Having mini-split installation done is a wise approach to solve comfort troubles in your residence. These systems don’t need ductwork to provide energy-efficient heating and cooling. Like any other home comfort system, they can run into troubles occasionally. Here are seven of the most frequent 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 might be a problem with the condensate drain or drain line. It’s common for a drain line to be clogged with mold, force water to back up and spill. Reach J & J Air Conditioning at 254-355-3833 for assistance and we’ll get your drain unclogged rapidly.

2. Mini-Split is Making Noise

Mini-splits typically don’t generate much noise when they’re running. But there are two times where they could create 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 happen if your mini-split switches into defrost mode to stop itself from icing over.

You shouldn’t be troubled if you hear these noises since they’re expected. However, if your mini-split keeps going into defrost mode, it’s a hint that something is up, including not enough refrigerant, a bad circuit board or defective sensors. Your J & J Air Conditioning HVAC technician will be able to find and resolve the issue quickly.

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 to blame. Like we discussed before, frozen coils may be the effect of insufficient refrigerant, a bad circuit board or broken sensors. Call us at 254-355-3833 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 uses refrigerant to transfer heat and keep your house pleasant. These leaks must be fixed by a licensed HVAC technician, so contact us at 254-355-3833 for support.

5. Mini-Split is Not Dehumidifying

Like an air conditioner, a mini-split is effective at dehumidifying during the summer. However, this can be halted by clogs in the condensate drain line. Another reason your mini-split air conditioner may not be dehumidifying very effectivelyis if it’s too big. A system that’s oversized will cool down a space too fast 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 typical 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 specialist like J & J Air Conditioning check and rinse the condensate drain and drain line, if needed.

Vinegar

If your mini-split smells like vinegar or has a sweet odor, you’re likely experiencing a refrigerant leak. Another sure sign that you don’t have ample refrigerant is a lack of cool air. Reach us at 254-355-3833 for assistance.

Fish

If your mini-split smells like fish, the following things things could be wrong. In some situations this smell means there are electrical issues or that there’s a leak. Either way, contact us at 254-355-3833 for help.

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 most instances, replacing the batteries will resolve the problem. If you’re still experiencing trouble, call us at 254-355-3833.
