7 Common Mini-Split Troubles and How to Resolve Them

July 12, 2021

Having mini-split installation done is a fantastic solution for solving comfort difficulties in your home. These systems don’t have to have ductwork to provide energy-efficient heating and cooling. Like any other home comfort system, they can experience problems occasionally. Here are seven of the most frequent mini-split issues 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 might be a situation with the condensate drain or drain line. It’s typical for a drain line to be clogged with mold, force water to back up and drip. Reach Gee & Missler Heating & Air Conditioning at 734-363-8907 for help and we’ll get your drain unclogged promptly.

2. Mini-Split is Making Noise

Mini-splits typically don’t create a lot of noise when they’re on. But there are two times where they may produce sounds.

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

You shouldn’t be worried 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 wrong, like not enough refrigerant, a faulty circuit board or broken sensors. Your Gee & Missler Heating & Air Conditioning HVAC professional will be able to find and resolve the issue 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 problem. Like we talked about before, frozen coils can be the effect of low refrigerant, a failing circuit board or malfunctioning sensors. Call us at 734-363-8907 for support.

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

If your mini-split is not cooling or blowing cold air, there might be a refrigerant leak. Your mini-split AC uses refrigerant to move heat and keep your residence cool. These leaks must be resolved by a licensed HVAC professional, so contact us at 734-363-8907 for help.

5. Mini-Split is Not Dehumidifying

Much like an air conditioner, a mini-split does a great job at dehumidifying during the summer. However, this can be halted by clogs in the condensate drain line. Another reason your mini-split air conditioner may not be dehumidifying very effectivelyis if it’s too big. A system that’s too big 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 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 Gee & Missler 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 likely dealing with a refrigerant leak. Another sure hint that you don’t have sufficient refrigerant is a low concentration of chilled air. Reach us at 734-363-8907 for support.

Fish

If your mini-split smells like fish, a few things could be wrong. Sometimes this smell means there are electrical issues or that there’s a leak. Nevertheless, contact us at 734-363-8907 for help.

7. Mini-Split Will Not Power On

If your mini-split will not power on, look at the remote first. If the batteries are dead, your mini-split won’t run. In many situations, putting in fresh batteries will resolve the trouble. If you’re still experiencing trouble, reach us at 734-363-8907.
