7 Common Mini-Split Issues and How to Repair Them

July 12, 2021

Having mini-split installation done is a good solution for solving comfort problems in your residence. These systems don’t require ductwork to deliver energy-efficient heating and cooling. Like any other home comfort system, they can run into problems from time to time. Here are seven of the most common mini-split issues 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 could be a situation with the condensate drain or drain line. It’s expected for a drain line to be clogged with mold, force water to back up and spill. Contact Air Temperature Control at 478-202-3170 for support and we’ll get your drain unplugged promptly.

2. Mini-Split is Making Noise

Mini-splits normally don’t create a lot of noise when they’re operating. But there are two times where they may make 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 happen if your mini-split switches into defrost mode to stop itself from freezing over.

You shouldn’t be worried if you hear these noises since they’re normal. However, if your mini-split keeps turning on defrost mode, it’s a hint that something is wrong, like low refrigerant, a faulty circuit board or broken sensors. Your Air Temperature Control HVAC pro will be able to pinpoint and resolve the situation 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 to blame. Like we talked about before, icy coils might be the result of low refrigerant, a faulty circuit board or broken sensors. Contact us at 478-202-3170 for help.

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 relies on refrigerant to transfer heat and keep your residence cool. These leaks must be fixed by a licensed HVAC technician, so reach us at 478-202-3170 for assistance.

5. Mini-Split is Not Dehumidifying

Like an air conditioner, a mini-split is effective at dehumidifying during the summer. However, this might be halted by mold 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 room too fast without having a moment 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 get 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 likely have a mold issue. Have a specialist like Air Temperature Control check and flush the condensate drain and drain line, if necessary.

Vinegar

If your mini-split smells like vinegar or has a sweet odor, you’re probably dealing with a refrigerant leak. Another certain clue that you don’t have ample refrigerant is a weak flow of chilled air. Call us at 478-202-3170 for assistance.

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. Nevertheless, call us at 478-202-3170 for assistance.

7. Mini-Split Will Not Power On

If your mini-split will not power on, check the remote first. If the batteries are dead, your mini-split won’t turn on. In the majority of experiences, replacing the batteries will fix the trouble. If you’re still running into trouble, reach us at 478-202-3170.
