7 Common Mini-Split Issues and How to Fix Them

July 12, 2021

Having mini-split installation done is a wise way to solve comfort issues in your house. These systems don’t have to have ductwork to give energy-efficient heating and cooling. Similar to any other home comfort system, they can have troubles occasionally. Here are seven of the most frequent mini-split issues and how you can resolve 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 problem 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. Contact Point Heating & Cooling at 715-504-0533 for support and we’ll get your drain unclogged quickly.

2. Mini-Split is Making Noise

Mini-splits normally don’t generate much noise when they’re on. But there are a few instances where they may produce sounds.

  • Popping or clicking: This can be due to the plastic housing expanding or contracting while the system is running.
  • Swooshing, crackling or gurgling: This can happen if your mini-split turns on defrost mode to prevent itself from icing up.

You shouldn’t be worried if you hear these noises because they’re expected. However, if your mini-split keeps switching into defrost mode, it’s a hint that something is wrong, including not enough refrigerant, a faulty circuit board or broken sensors. Your Point Heating & Cooling HVAC pro will be able to find and solve the situation quickly.

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 discussed prior to this, iced-over coils might be the effect of low refrigerant, a failing circuit board or malfunctioning sensors. Reach us at 715-504-0533 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 house comfortable. These leaks must be fixed by a licensed HVAC tech, so reach us at 715-504-0533 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 can be halted by clogs in the condensate drain line. Another reason your mini-split air conditioner may not be dehumidifying very efficientlyis if it’s too large. A system that’s too large will cool down a room too quickly 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 common smells and what they mean.

Musty, Sour or Mildew

If your mini-split smells musty, sour or like mildew, you might have a mold issue. Have a pro like Point Heating & Cooling examine 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 likely experiencing a refrigerant leak. Another surefire hint that you don’t have enough refrigerant is a lack of cold air. Contact us at 715-504-0533 for assistance.

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, call us at 715-504-0533 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 the majority of instances, putting in new batteries will solve the trouble. If you’re still experiencing trouble, contact us at 715-504-0533.
