7 Common Mini-Split Issues and How to Resolve Them

July 12, 2021

Having mini-split installation done is a great approach to solve comfort difficulties in your house. These systems don’t require ductwork to provide energy-efficient heating and cooling. Much like any other home comfort system, they can have issues occasionally. Here are seven of the most common mini-split issues and how you can resolve 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 common for a drain line to get clogged with mold, force water to back up and spill. Call Gillman Heating and Air at 478-202-3076 for support and we’ll get your drain unplugged rapidly.

2. Mini-Split is Making Noise

Mini-splits usually don’t create a lot of noise when they’re running. But there are a couple of instances where they might create sounds.

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

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 sign that something is wrong, such as low refrigerant, a bad circuit board or broken sensors. Your Gillman Heating and Air HVAC technician will be able to pinpoint 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 could be the issue. Like we talked about before, icy coils may be the result of not enough refrigerant, a faulty circuit board or malfunctioning sensors. Reach us at 478-202-3076 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 needs refrigerant to move heat and keep your residence comfortable. These leaks must be resolved by a licensed HVAC tech, so contact us at 478-202-3076 for assistance.

5. Mini-Split is Not Dehumidifying

Similar to an air conditioner, a mini-split is effective at dehumidifying during the summer. However, this can be interrupted by blockages in the condensate drain line. Another reason your mini-split air conditioner may not be dehumidifying very effectivelyis if it’s too large. A system that’s too big will cool down an area too rapidly without having a moment 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 might have a mold issue. Have a pro like Gillman Heating and Air check and rinse 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 sure hint that you don’t have ample refrigerant is a lack of chilled air. Call us at 478-202-3076 for support.

Fish

If your mini-split smells like fish, a few things could be wrong. In some situations this smell means there is an electrical problem or that there’s a leak. Nevertheless, call us at 478-202-3076 for support.

7. Mini-Split Will Not Power On

If your mini-split will not power on, look at the remote first. If the batteries are out of juice, your mini-split won’t run. In most instances, putting in fresh batteries will fix the issue. If you’re still experiencing trouble, contact us at 478-202-3076.
