7 Common Mini-Split Problems and How to Fix Them

July 12, 2021

Having mini-split installation done is a wise approach to solve comfort issues in your residence. These systems don’t need ductwork to provide energy-efficient heating and cooling. Similar to any other home comfort system, they can run into troubles occasionally. Here are seven of the most typical 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 could be a situation 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 leak. Reach Honke Heating & AC at 503-663-8033 for support and we’ll get your drain unplugged quickly.

2. Mini-Split is Making Noise

Mini-splits normally don’t generate much noise when they’re operating. But there are two instances where they might create sounds.

  • Popping or clicking: This can be due to the plastic housing expanding or contracting while the system is operating.
  • Swooshing, crackling or gurgling: This can happen if your mini-split goes into defrost mode to stop itself from icing up.

You shouldn’t be alarmed if you hear these noises since they’re typical. However, if your mini-split keeps going into defrost mode, it’s a symptom that something is up, like insufficient refrigerant, a faulty circuit board or malfunctioning sensors. Your Honke Heating & AC HVAC tech will be able to locate and resolve the situation fast.

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 mentioned before, iced-over coils might be the effect of insufficient refrigerant, a bad circuit board or defective sensors. Call us at 503-663-8033 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 shift heat and keep your home pleasant. These leaks must be repaired by a licensed HVAC technician, so call us at 503-663-8033 for assistance.

5. Mini-Split is Not Dehumidifying

Much like an air conditioner, a mini-split is effective at dehumidifying during the summer. However, this could be interrupted by clogs in the condensate drain line. Another reason your mini-split air conditioner may not be dehumidifying very effectivelyis if it’s oversized. A system that’s too large will cool down a room too quickly without having time 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 get 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 may have a mold issue. Have a specialist like Honke Heating & AC examine and rinse the condensate drain and drain line, if needed.

Vinegar

If your mini-split smells like vinegar or has a sweet odor, you’re probably experiencing a refrigerant leak. Another surefire sign that you don’t have ample refrigerant is a low concentration of cold air. Contact us at 503-663-8033 for assistance.

Fish

If your mini-split smells like fish, a couple of things could be wrong. In some situations this smell means there are electrical issues or that there’s a leak. Nevertheless, call us at 503-663-8033 for support.

7. Mini-Split Will Not Power On

If your mini-split will not power on, check the remote first. If the batteries are bad, your mini-split won’t run. In most situations, putting in new batteries will solve the problem. If you’re still having trouble, call us at 503-663-8033.
