7 Common Mini-Split Troubles and How to Resolve Them

July 12, 2021

Having mini-split installation done is a smart solution for solving comfort issues in your house. These systems don’t have to have ductwork to deliver energy-efficient heating and cooling. Similar to any other home comfort system, they can experience troubles sometimes. Here are seven of the most common 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 a situation with the condensate drain or drain line. It’s typical for a drain line to get clogged with mold, force water to back up and leak. Contact Comfort Zone Inc at 239-214-0411 for help and we’ll get your drain unblocked quickly.

2. Mini-Split is Making Noise

Mini-splits usually don’t create a lot of noise when they’re on. But there are a couple of instances where they could 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 prevent itself from icing up.

You shouldn’t be alarmed if you hear these noises as they’re typical. However, if your mini-split keeps going into defrost mode, it’s a hint that something is up, including low refrigerant, a flawed circuit board or broken sensors. Your Comfort Zone Inc HVAC technician will be able to pinpoint and resolve 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 talked about before, icy coils might be the effect of low refrigerant, a faulty circuit board or broken sensors. Reach us at 239-214-0411 for assistance.

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

If your mini-split is not cooling or blowing cold air, there may be a refrigerant leak. Your mini-split AC relies on refrigerant to shift heat and keep your home pleasant. These leaks must be repaired by a licensed HVAC tech, so reach us at 239-214-0411 for assistance.

5. Mini-Split is Not Dehumidifying

Similar to an air conditioner, a mini-split is efficient at dehumidifying during the summer. However, this can be halted by mold in the condensate drain line. Another reason your mini-split air conditioner may not be dehumidifying very well is if it’s too big. A system that’s too large will cool down an area too quickly without having a moment 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 grab 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 pro like Comfort Zone Inc 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 certain hint that you don’t have enough refrigerant is a weak flow of cool air. Contact us at 239-214-0411 for help.

Fish

If your mini-split smells like fish, the following things things could be wrong. Sometimes this smell means there is electrical trouble or that there’s a leak. Either way, contact us at 239-214-0411 for help.

7. Mini-Split Will Not Power On

If your mini-split will not power on, check the remote first. If the batteries are dead, your mini-split won’t switch on. In most instances, putting in new batteries will solve the situation. If you’re still experiencing trouble, call us at 239-214-0411.
