7 Common Mini-Split Issues and How to Fix Them

July 12, 2021

Having mini-split installation done is a wise approach to solve comfort problems in your house. These systems don’t require ductwork to give energy-efficient heating and cooling. Much like any other home comfort system, they can have troubles from time to time. Here are seven of the most common mini-split problems 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 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 drip. Reach James Heating & A/C, Inc at 336-853-6070 for assistance and we’ll get your drain unplugged quickly.

2. Mini-Split is Making Noise

Mini-splits normally don’t create a lot of noise when they’re running. But there are two times where they could make sounds.

  • Popping or clicking: This can be because of the plastic housing expanding or contracting while the system is on.
  • Swooshing, crackling or gurgling: This can take place if your mini-split turns on defrost mode to stop itself from icing up.

You shouldn’t be worried if you hear these noises as they’re expected. However, if your mini-split keeps turning on defrost mode, it’s a symptom that something is up, including low refrigerant, a flawed circuit board or broken sensors. Your James Heating & A/C, Inc HVAC technician will be able to find and solve the situation 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 to blame. Like we talked about prior to this, frozen coils can be the effect of low refrigerant, a bad circuit board or defective sensors. Contact us at 336-853-6070 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 relies on refrigerant to shift heat and keep your house comfortable. These leaks must be fixed by a licensed HVAC tech, so reach us at 336-853-6070 for support.

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 may be halted 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 large will cool down a room too rapidly without having a moment 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 tell you 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 professional like James Heating & A/C, Inc examine 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 probably encountering a refrigerant leak. Another surefire clue that you don’t have sufficient refrigerant is a weak flow of cold air. Call us at 336-853-6070 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. Nevertheless, reach us at 336-853-6070 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 most instances, putting in fresh batteries will fix the issue. If you’re still running into trouble, call us at 336-853-6070.
