7 Common Mini-Split Issues and How to Resolve Them

July 12, 2021

Having mini-split installation done is a good way to solve comfort troubles in your home. These systems don’t need ductwork to deliver energy-efficient heating and cooling. Like any other home comfort system, they can experience troubles occasionally. Here are seven of the most common mini-split problems 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 could be a situation 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 leak. Call Tri County Climate Control LLC at 541-238-2797 for assistance and we’ll get your drain unclogged promptly.

2. Mini-Split is Making Noise

Mini-splits normally don’t generate much noise when they’re running. But there are two situations where they may create sounds.

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

You shouldn’t be troubled if you hear these noises as they’re typical. However, if your mini-split keeps going into defrost mode, it’s a clue that something is up, including insufficient refrigerant, a bad circuit board or broken sensors. Your Tri County Climate Control LLC HVAC technician will be able to find 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 the issue. Like we discussed previously, frozen coils may be the effect of not enough refrigerant, a faulty circuit board or malfunctioning sensors. Reach us at 541-238-2797 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 uses refrigerant to move heat and keep your home cool. These leaks must be fixed by a licensed HVAC pro, so contact us at 541-238-2797 for support.

5. Mini-Split is Not Dehumidifying

Similar to an air conditioner, a mini-split is efficient at dehumidifying during the summer. However, this might be stopped by clogs in the condensate drain line. Another reason your mini-split air conditioner may not be dehumidifying very well is if it’s oversized. A system that’s oversized will cool down a room too fast 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 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 likely have a mold issue. Have a pro like Tri County Climate Control LLC check and flush the condensate drain and drain line, if required.

Vinegar

If your mini-split smells like vinegar or has a sweet odor, you’re possibly encountering a refrigerant leak. Another sure sign that you don’t have sufficient refrigerant is a weak flow of chilled air. Reach us at 541-238-2797 for help.

Fish

If your mini-split smells like fish, a couple of things could be wrong. Sometimes this smell means there is an electrical problem or that there’s a leak. Either way, call us at 541-238-2797 for support.

7. Mini-Split Will Not Power On

If your mini-split will not power on, examine the remote first. If the batteries are dead, your mini-split won’t switch on. In many situations, putting in new batteries will resolve the issue. If you’re still having trouble, contact us at 541-238-2797.
