7 Common Mini-Split Issues and How to Resolve Them

July 12, 2021

Having mini-split installation done is a smart way to solve comfort troubles in your residence. These systems don’t need ductwork to provide energy-efficient heating and cooling. Like any other home comfort system, they can run into troubles sometimes. Here are seven of the most frequent 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 might be an issue 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 drip. Call Interstate Heating & Air Conditioning at 402-509-5940 for assistance and we’ll get your drain unclogged quickly.

2. Mini-Split is Making Noise

Mini-splits normally don’t create a lot of noise when they’re operating. But there are a few 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 occur if your mini-split goes into defrost mode to keep itself from icing up.

You shouldn’t be worried if you hear these noises as they’re normal. However, if your mini-split keeps going into defrost mode, it’s a sign that something is off, including insufficient refrigerant, a flawed circuit board or broken sensors. Your Interstate Heating & Air Conditioning HVAC technician will be able to locate and solve the problem 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 discussed previously, icy coils may be the result of insufficient refrigerant, a bad circuit board or malfunctioning sensors. Reach us at 402-509-5940 for help.

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 repaired by a licensed HVAC pro, so call us at 402-509-5940 for help.

5. Mini-Split is Not Dehumidifying

Much like an air conditioner, a mini-split is effective at dehumidifying during the summer. However, this may be halted by mold in the condensate drain line. Another reason your mini-split air conditioner may not be dehumidifying very effectivelyis if it’s oversized. A system that’s too large will cool down a space too fast without having a chance to dehumidify it. Mini-split size is based 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 Interstate Heating & Air Conditioning inspect and flush the condensate drain and drain line, if needed.

Vinegar

If your mini-split smells like vinegar or has a sweet odor, you’re probably dealing with a refrigerant leak. Another surefire hint that you don’t have enough refrigerant is a low concentration of chilled air. Contact us at 402-509-5940 for help.

Fish

If your mini-split smells like fish, a few things could be wrong. In some instances this smell means there is electrical trouble or that there’s a leak. Regardless, call us at 402-509-5940 for help.

7. Mini-Split Will Not Power On

If your mini-split will not power on, look at the remote first. If the batteries are out of juice, your mini-split won’t turn on. In the majority of situations, putting in fresh batteries will fix the problem. If you’re still having trouble, contact us at 402-509-5940.
