7 Common Mini-Split Problems and How to Fix Them

July 12, 2021

Having mini-split installation done is an excellent approach to solve comfort troubles in your residence. These systems don’t require ductwork to provide energy-efficient heating and cooling. Similar to any other home comfort system, they can experience issues occasionally. Here are seven of the most typical 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 may 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 drip. Reach American HVAC Inc at 408-215-1018 for help and we’ll get your drain unplugged rapidly.

2. Mini-Split is Making Noise

Mini-splits typically don’t make much noise when they’re operating. But there are two instances where they may make sounds.

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

You shouldn’t be worried if you hear these noises as they’re normal. However, if your mini-split keeps switching into defrost mode, it’s a clue that something is up, including not enough refrigerant, a faulty circuit board or broken sensors. Your American HVAC Inc HVAC technician will be able to locate and correct 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 could be to blame. Like we talked about previously, icy coils can be the effect of insufficient refrigerant, a bad circuit board or broken sensors. Call us at 408-215-1018 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 home comfortable. These leaks must be resolved by a licensed HVAC tech, so contact us at 408-215-1018 for support.

5. Mini-Split is Not Dehumidifying

Much like an air conditioner, a mini-split is effective at dehumidifying during the summer. However, this may be stopped by blockages 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 a space too rapidly without having a chance to dehumidify it. Mini-split size is calculated 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 likely have a mold issue. Have a professional like American HVAC Inc examine and flush 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 clue that you don’t have sufficient refrigerant is a weak flow of cold air. Reach us at 408-215-1018 for help.

Fish

If your mini-split smells like fish, a couple of things could be wrong. Sometimes this smell means there is electrical trouble or that there’s a leak. Regardless, contact us at 408-215-1018 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 run. In many instances, replacing the batteries will fix the trouble. If you’re still running into trouble, reach us at 408-215-1018.
