7 Common Mini-Split Troubles and How to Resolve Them

July 12, 2021

Having mini-split installation done is a great approach to solve comfort problems in your home. These systems don’t need ductwork to deliver energy-efficient heating and cooling. Much like any other home comfort system, they can have troubles occasionally. Here are seven of the most typical mini-split problems 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 may 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 spill. Reach All Weather Heating & Air Conditioning Inc at 256-801-4701 for help and we’ll get your drain unclogged rapidly.

2. Mini-Split is Making Noise

Mini-splits usually don’t create a lot of noise when they’re on. But there are two instances where they might make sounds.

  • Popping or clicking: This can be because of the plastic housing expanding or contracting while the system is operating.
  • Swooshing, crackling or gurgling: This can occur if your mini-split switches into defrost mode to stop itself from icing up.

You shouldn’t be troubled if you hear these noises since they’re typical. However, if your mini-split keeps switching into defrost mode, it’s a clue that something is off, including not enough refrigerant, a flawed circuit board or defective sensors. Your All Weather Heating & Air Conditioning Inc HVAC tech will be able to pinpoint and correct the situation rapidly.

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

If your mini-split is not heating or blowing hot air, frozen coils may be to blame. Like we discussed prior to this, icy coils might be the effect of not enough refrigerant, a bad circuit board or malfunctioning sensors. Contact us at 256-801-4701 for assistance.

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 relies on refrigerant to move heat and keep your residence comfortable. These leaks must be repaired by a licensed HVAC tech, so reach us at 256-801-4701 for assistance.

5. Mini-Split is Not Dehumidifying

Like an air conditioner, a mini-split does a great job at dehumidifying during the summer. However, this may be halted by clogs in the condensate drain line. Another reason your mini-split air conditioner may not be dehumidifying properlyis if it’s oversized. A system that’s too large will cool down an area too rapidly without having a chance 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 tell you 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 pro like All Weather Heating & Air Conditioning Inc check and rinse the condensate drain and drain line, if required.

Vinegar

If your mini-split smells like vinegar or has a sweet odor, you’re probably dealing with a refrigerant leak. Another certain hint that you don’t have enough refrigerant is a low concentration of cool air. Reach us at 256-801-4701 for support.

Fish

If your mini-split smells like fish, the following things things could be wrong. In some instances this smell means there are electrical issues or that there’s a leak. Regardless, call us at 256-801-4701 for support.

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 the majority of experiences, replacing the batteries will fix the issue. If you’re still running into trouble, call us at 256-801-4701.
