7 Common Mini-Split Problems and How to Fix Them

July 12, 2021

Having mini-split installation done is a wise solution for solving comfort troubles in your house. These systems don’t need ductwork to deliver energy-efficient heating and cooling. Similar to any other home comfort system, they can have issues from time to time. Here are seven of the most common mini-split troubles 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 expected for a drain line to get clogged with mold, force water to back up and spill. Reach Garoken Energy Co. Inc. at 503-374-1934 for support and we’ll get your drain unclogged promptly.

2. Mini-Split is Making Noise

Mini-splits typically don’t generate much noise when they’re operating. But there are a few instances where they could create 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 take place if your mini-split turns on defrost mode to stop itself from freezing over.

You shouldn’t be alarmed if you hear these noises as they’re normal. However, if your mini-split keeps turning on defrost mode, it’s a hint that something is off, including not enough refrigerant, a flawed circuit board or malfunctioning sensors. Your Garoken Energy Co. Inc. HVAC technician will be able to find and solve 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 issue. Like we mentioned before, frozen coils can be the effect of low refrigerant, a faulty circuit board or defective sensors. Reach us at 503-374-1934 for assistance.

4. Mini-Split is Not Cooling or Blowing Cold Air

If your mini-split is not cooling or blowing cold air, there may be a refrigerant leak. Your mini-split AC needs refrigerant to transfer heat and keep your home cool. These leaks must be resolved by a licensed HVAC professional, so call us at 503-374-1934 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 might 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 big. A system that’s too large will cool down an area too fast 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 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 professional like Garoken Energy Co. Inc. check 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 probably encountering a refrigerant leak. Another sure clue that you don’t have enough refrigerant is a low concentration of cold air. Reach us at 503-374-1934 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 503-374-1934 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 bad, your mini-split won’t switch on. In the majority of instances, replacing the batteries will resolve the trouble. If you’re still experiencing trouble, reach us at 503-374-1934.
