7 Common Mini-Split Problems and How to Fix Them

July 12, 2021

Having mini-split installation done is a good approach to solve comfort problems in your home. These systems don’t need ductwork to give energy-efficient heating and cooling. Much like any other home comfort system, they can run into issues occasionally. Here are seven of the most common mini-split problems 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 an issue with the condensate drain or drain line. It’s typical for a drain line to get clogged with mold, force water to back up and spill. Contact Redhawk Heating & Air Conditioning at 432-237-0168 for support and we’ll get your drain unclogged quickly.

2. Mini-Split is Making Noise

Mini-splits typically don’t make much noise when they’re running. But there are a few situations where they may produce 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 over.

You shouldn’t be troubled if you hear these noises since they’re normal. However, if your mini-split keeps switching into defrost mode, it’s a symptom that something is up, such as low refrigerant, a flawed circuit board or malfunctioning sensors. Your Redhawk Heating & Air Conditioning HVAC pro will be able to pinpoint 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, icy coils might be the problem. Like we discussed prior to this, frozen coils can be the result of not enough refrigerant, a faulty circuit board or malfunctioning sensors. Contact us at 432-237-0168 for help.

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 relies on refrigerant to transfer heat and keep your residence cool. These leaks must be fixed by a licensed HVAC professional, so call us at 432-237-0168 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 may be interrupted by clogs 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 oversized will cool down an area too quickly 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 grab 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 likely have a mold issue. Have a pro like Redhawk Heating & Air Conditioning examine and clean the condensate drain and drain line, if needed.

Vinegar

If your mini-split smells like vinegar or has a sweet odor, you’re likely encountering a refrigerant leak. Another surefire sign that you don’t have sufficient refrigerant is a low concentration of chilled air. Call us at 432-237-0168 for help.

Fish

If your mini-split smells like fish, a couple of things could be wrong. Sometimes this smell means there are electrical issues or that there’s a leak. Nevertheless, call us at 432-237-0168 for help.

7. Mini-Split Will Not Power On

If your mini-split will not power on, examine the remote first. If the batteries are out of juice, your mini-split won’t run. In most situations, putting in fresh batteries will resolve the trouble. If you’re still having trouble, call us at 432-237-0168.
