7 Common Mini-Split Problems and How to Fix Them

July 12, 2021

Having mini-split installation done is a smart solution for solving comfort issues in your home. These systems don’t have to have ductwork to deliver energy-efficient heating and cooling. Similar to any other home comfort system, they can experience problems from time to time. Here are seven of the most frequent 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 a problem 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. Call Service Max Heating & Air Conditioning at 360-255-5857 for help and we’ll get your drain unplugged promptly.

2. Mini-Split is Making Noise

Mini-splits usually don’t make much noise when they’re running. But there are a couple of times where they might produce sounds.

  • Popping or clicking: This can be because 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 keep itself from freezing up.

You shouldn’t be alarmed if you hear these noises since they’re expected. However, if your mini-split keeps going into defrost mode, it’s a clue that something is off, including low refrigerant, a flawed circuit board or broken sensors. Your Service Max Heating & Air Conditioning HVAC tech will be able to pinpoint and solve the problem fast.

3. Mini-Split is Not Heating or Blowing Hot Air

If your mini-split is not heating or blowing hot air, frozen coils could be to blame. Like we mentioned previously, icy coils can be the effect of not enough refrigerant, a failing circuit board or defective sensors. Reach us at 360-255-5857 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 uses refrigerant to shift heat and keep your residence cold. These leaks must be resolved by a licensed HVAC tech, so reach us at 360-255-5857 for help.

5. Mini-Split is Not Dehumidifying

Much like 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 well is if it’s too large. A system that’s too big will cool down a room 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 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 professional like Service Max Heating & Air Conditioning 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 possibly experiencing a refrigerant leak. Another sure hint that you don’t have ample refrigerant is a lack of chilled air. Reach us at 360-255-5857 for assistance.

Fish

If your mini-split smells like fish, the following things things could be wrong. In some situations this smell means there is electrical trouble or that there’s a leak. Either way, contact us at 360-255-5857 for assistance.

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 switch on. In most experiences, putting in new batteries will resolve the situation. If you’re still having trouble, reach us at 360-255-5857.
