7 Common Mini-Split Issues and How to Resolve Them

July 12, 2021

Having mini-split installation done is a fantastic approach to solve comfort issues in your residence. These systems don’t have to have ductwork to provide energy-efficient heating and cooling. Like any other home comfort system, they can run into 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 an issue with the condensate drain or drain line. It’s common for a drain line to be clogged with mold, force water to back up and drip. Reach Forster Heating at 530-885-8081 for help and we’ll get your drain unplugged rapidly.

2. Mini-Split is Making Noise

Mini-splits normally don’t generate much noise when they’re operating. But there are a few times where they could produce sounds.

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

You shouldn’t be alarmed if you hear these noises because they’re normal. However, if your mini-split keeps turning on defrost mode, it’s a sign that something is wrong, like not enough refrigerant, a bad circuit board or broken sensors. Your Forster Heating HVAC professional will be able to locate 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 could be the problem. Like we talked about before, icy coils may be the result of insufficient refrigerant, a failing circuit board or malfunctioning sensors. Reach us at 530-885-8081 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 needs refrigerant to move heat and keep your residence pleasant. These leaks must be fixed by a licensed HVAC pro, so call us at 530-885-8081 for assistance.

5. Mini-Split is Not Dehumidifying

Like an air conditioner, a mini-split is efficient at dehumidifying during the summer. However, this can 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 too large. A system that’s too large will cool down an area too rapidly without having time 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 tell you 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 may have a mold issue. Have a specialist like Forster Heating inspect 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 likely dealing with a refrigerant leak. Another certain hint that you don’t have ample refrigerant is a lack of chilled air. Call us at 530-885-8081 for support.

Fish

If your mini-split smells like fish, a couple of things could be wrong. In some instances this smell means there is an electrical problem or that there’s a leak. Either way, call us at 530-885-8081 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 switch on. In the majority of experiences, putting in new batteries will resolve the issue. If you’re still experiencing trouble, reach us at 530-885-8081.
