7 Common Mini-Split Problems and How to Resolve Them

July 12, 2021

Having mini-split installation done is a wise way to solve comfort problems in your residence. These systems don’t need ductwork to deliver energy-efficient heating and cooling. Similar to any other home comfort system, they can experience problems sometimes. Here are seven of the most typical mini-split issues 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 might be a situation 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 Willco Air Conditioning, Refrigeration & Heating Inc. at 862-345-6896 for assistance and we’ll get your drain unplugged rapidly.

2. Mini-Split is Making Noise

Mini-splits usually don’t make much noise when they’re running. But there are two times where they might create sounds.

  • Popping or clicking: This can be the result of the plastic housing expanding or contracting while the system is operating.
  • Swooshing, crackling or gurgling: This can occur if your mini-split switches into defrost mode to stop itself from icing over.

You shouldn’t be worried if you hear these noises as they’re expected. However, if your mini-split keeps going into defrost mode, it’s a sign that something is up, like low refrigerant, a faulty circuit board or malfunctioning sensors. Your Willco Air Conditioning, Refrigeration & Heating Inc. HVAC pro will be able to locate and resolve the problem rapidly.

3. Mini-Split is Not Heating or Blowing Hot Air

If your mini-split is not heating or blowing hot air, frozen coils might be to blame. Like we talked about previously, frozen coils could be the result of low refrigerant, a failing circuit board or defective sensors. Reach us at 862-345-6896 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 uses refrigerant to move heat and keep your home cool. These leaks must be repaired by a licensed HVAC pro, so call us at 862-345-6896 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 could 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 oversized. A system that’s oversized will cool down a room too quickly without having time 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 grab your attention that something is wrong. Here are five of the most usual 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 pro like Willco Air Conditioning, Refrigeration & Heating Inc. inspect and flush the condensate drain and drain line, if required.

Vinegar

If your mini-split smells like vinegar or has a sweet odor, you’re possibly encountering a refrigerant leak. Another certain sign that you don’t have enough refrigerant is a lack of chilled air. Reach us at 862-345-6896 for assistance.

Fish

If your mini-split smells like fish, a few things could be wrong. In some instances this smell means there are electrical issues or that there’s a leak. Nevertheless, call us at 862-345-6896 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 bad, your mini-split won’t switch on. In the majority of instances, replacing the batteries will fix the situation. If you’re still running into trouble, reach us at 862-345-6896.
