7 Common Mini-Split Problems and How to Repair Them

July 12, 2021

Having mini-split installation done is a great way to solve comfort troubles in your house. These systems don’t have to have ductwork to provide energy-efficient heating and cooling. Similar to any other home comfort system, they can have troubles from time to time. Here are seven of the most typical 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 may be a situation with the condensate drain or drain line. It’s expected for a drain line to get clogged with mold, force water to back up and leak. Reach Dearing's Service & Solutions at 812-200-5844 for assistance and we’ll get your drain unblocked rapidly.

2. Mini-Split is Making Noise

Mini-splits normally don’t make much noise when they’re running. But there are a couple of instances where they may produce sounds.

  • Popping or clicking: This can be the result of the plastic housing expanding or contracting while the system is operating.
  • Swooshing, crackling or gurgling: This can happen if your mini-split goes into defrost mode to stop itself from freezing up.

You shouldn’t be worried if you hear these noises since they’re normal. However, if your mini-split keeps turning on defrost mode, it’s a sign that something is up, including not enough refrigerant, a faulty circuit board or malfunctioning sensors. Your Dearing's Service & Solutions HVAC pro will be able to find and resolve the issue quickly.

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

If your mini-split is not heating or blowing hot air, icy coils may be the problem. Like we talked about before, frozen coils could be the consequence of insufficient refrigerant, a failing circuit board or malfunctioning sensors. Contact us at 812-200-5844 for support.

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 comfortable. These leaks must be resolved by a licensed HVAC technician, so reach us at 812-200-5844 for help.

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 halted by blockages in the condensate drain line. Another reason your mini-split air conditioner may not be dehumidifying very effectivelyis if it’s too large. A system that’s oversized will cool down an area 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 likely have a mold issue. Have a pro like Dearing's Service & Solutions examine and clean the condensate drain and drain line, if necessary.

Vinegar

If your mini-split smells like vinegar or has a sweet odor, you’re probably encountering a refrigerant leak. Another sure sign that you don’t have ample refrigerant is a low concentration of chilled air. Contact us at 812-200-5844 for assistance.

Fish

If your mini-split smells like fish, a couple of things could be wrong. In some situations this smell means there are electrical issues or that there’s a leak. Regardless, contact us at 812-200-5844 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 out of juice, your mini-split won’t switch on. In the majority of experiences, putting in new batteries will fix the trouble. If you’re still running into trouble, reach us at 812-200-5844.
