7 Common Mini-Split Troubles and How to Repair Them

July 12, 2021

Having mini-split installation done is a fantastic solution for solving comfort problems in your home. These systems don’t require 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 troubles and how you can fix 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 be clogged with mold, force water to back up and drip. Call Hopper Heating and Air at 704-233-7363 for assistance and we’ll get your drain unblocked promptly.

2. Mini-Split is Making Noise

Mini-splits usually don’t create a lot of noise when they’re running. But there are a few times where they may make 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 keep itself from freezing over.

You shouldn’t be troubled if you hear these noises because they’re typical. However, if your mini-split keeps switching into defrost mode, it’s a clue that something is off, including low refrigerant, a bad circuit board or broken sensors. Your Hopper Heating and Air HVAC tech 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 could be the problem. Like we discussed previously, frozen coils may be the effect of insufficient refrigerant, a failing circuit board or broken sensors. Call us at 704-233-7363 for assistance.

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 needs refrigerant to shift heat and keep your residence cool. These leaks must be resolved by a licensed HVAC technician, so contact us at 704-233-7363 for help.

5. Mini-Split is Not Dehumidifying

Similar to an air conditioner, a mini-split is effective at dehumidifying during the summer. However, this could be halted 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 room too quickly without having a chance 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 common 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 pro like Hopper Heating and Air inspect and clean 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 enough refrigerant is a low concentration of cold air. Reach us at 704-233-7363 for support.

Fish

If your mini-split smells like fish, a few things could be wrong. Sometimes this smell means there is electrical trouble or that there’s a leak. Either way, contact us at 704-233-7363 for support.

7. Mini-Split Will Not Power On

If your mini-split will not power on, examine the remote first. If the batteries are out of juice, your mini-split won’t turn on. In many situations, putting in new batteries will resolve the trouble. If you’re still having trouble, reach us at 704-233-7363.
