7 Common Mini-Split Troubles and How to Fix Them

July 12, 2021

Having mini-split installation done is a wise approach to solve comfort problems in your house. These systems don’t have to have 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 frequent mini-split troubles 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 might be an issue with the condensate drain or drain line. It’s typical for a drain line to become clogged with mold, force water to back up and spill. Contact Cool Power LLC at 631-246-4029 for assistance and we’ll get your drain unclogged promptly.

2. Mini-Split is Making Noise

Mini-splits normally don’t make much noise when they’re operating. But there are a couple of situations where they might make sounds.

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

You shouldn’t be alarmed if you hear these noises since they’re typical. However, if your mini-split keeps going into defrost mode, it’s a sign that something is off, like not enough refrigerant, a flawed circuit board or broken sensors. Your Cool Power LLC HVAC tech will be able to pinpoint and resolve the situation fast.

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

If your mini-split is not heating or blowing hot air, ice on the coils may be the problem. Like we discussed before, iced-over coils might be the result of low refrigerant, a failing circuit board or defective sensors. Reach us at 631-246-4029 for support.

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 uses refrigerant to shift heat and keep your home comfortable. These leaks must be resolved by a licensed HVAC professional, so call us at 631-246-4029 for help.

5. Mini-Split is Not Dehumidifying

Much like an air conditioner, a mini-split is efficient at dehumidifying during the summer. However, this can be interrupted by blockages in the condensate drain line. Another reason your mini-split air conditioner may not be dehumidifying properlyis if it’s too large. 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 get 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 could have a mold issue. Have a professional like Cool Power LLC check and rinse the condensate drain and drain line, if necessary.

Vinegar

If your mini-split smells like vinegar or has a sweet odor, you’re possibly dealing with a refrigerant leak. Another certain hint that you don’t have enough refrigerant is a lack of cool air. Reach us at 631-246-4029 for help.

Fish

If your mini-split smells like fish, the following things things could be wrong. In some instances this smell means there is an electrical problem or that there’s a leak. Regardless, reach us at 631-246-4029 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 turn on. In most situations, putting in fresh batteries will resolve the issue. If you’re still experiencing trouble, reach us at 631-246-4029.
