7 Common Mini-Split Troubles and How to Fix Them

July 12, 2021

Having mini-split installation done is a smart way to solve comfort difficulties in your residence. These systems don’t need ductwork to deliver energy-efficient heating and cooling. Like any other home comfort system, they can have troubles from time to time. Here are seven of the most common mini-split troubles and how you can repair 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 problem with the condensate drain or drain line. It’s common for a drain line to get clogged with mold, force water to back up and spill. Call Gilray Heating and Cooling at 715-301-0727 for support and we’ll get your drain unclogged rapidly.

2. Mini-Split is Making Noise

Mini-splits typically don’t create a lot of noise when they’re on. But there are two instances where they could create 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 freezing up.

You shouldn’t be alarmed if you hear these noises since they’re expected. However, if your mini-split keeps switching into defrost mode, it’s a sign that something is up, such as not enough refrigerant, a bad circuit board or defective sensors. Your Gilray Heating and Cooling HVAC tech will be able to find and solve the issue rapidly.

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

If your mini-split is not heating or blowing hot air, frozen coils might be the problem. Like we mentioned prior to this, frozen coils can be the effect of insufficient refrigerant, a failing circuit board or defective sensors. Reach us at 715-301-0727 for help.

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 relies on refrigerant to transfer heat and keep your house cold. These leaks must be repaired by a licensed HVAC professional, so contact us at 715-301-0727 for support.

5. Mini-Split is Not Dehumidifying

Like an air conditioner, a mini-split is efficient 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 very efficientlyis if it’s too big. A system that’s too big will cool down a space too rapidly 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 typical 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 Gilray Heating and Cooling examine and rinse the condensate drain and drain line, if needed.

Vinegar

If your mini-split smells like vinegar or has a sweet odor, you’re possibly experiencing a refrigerant leak. Another surefire sign that you don’t have enough refrigerant is a lack of cold air. Reach us at 715-301-0727 for help.

Fish

If your mini-split smells like fish, a couple of things could be wrong. In some instances this smell means there is an electrical problem or that there’s a leak. Regardless, call us at 715-301-0727 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 out of juice, your mini-split won’t turn on. In many experiences, putting in new batteries will fix the problem. If you’re still having trouble, contact us at 715-301-0727.
