7 Common Mini-Split Troubles and How to Repair Them

July 12, 2021

Having mini-split installation done is a smart solution for solving comfort troubles in your residence. These systems don’t require ductwork to deliver energy-efficient heating and cooling. Much like any other home comfort system, they can have troubles from time to time. Here are seven of the most typical mini-split issues 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 could be a problem with the condensate drain or drain line. It’s expected for a drain line to become clogged with mold, force water to back up and leak. Contact AW Heating & Air Conditioning at 402-438-7992 for help and we’ll get your drain unplugged rapidly.

2. Mini-Split is Making Noise

Mini-splits usually don’t generate much noise when they’re operating. But there are two instances where they could make 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 icing over.

You shouldn’t be troubled if you hear these noises because they’re expected. However, if your mini-split keeps going into defrost mode, it’s a hint that something is off, like insufficient refrigerant, a faulty circuit board or malfunctioning sensors. Your AW Heating & Air Conditioning HVAC pro will be able to locate and resolve the problem fast.

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 mentioned prior to this, iced-over coils could be the consequence of low refrigerant, a faulty circuit board or malfunctioning sensors. Contact us at 402-438-7992 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 shift heat and keep your house comfortable. These leaks must be fixed by a licensed HVAC technician, so call us at 402-438-7992 for support.

5. Mini-Split is Not Dehumidifying

Like an air conditioner, a mini-split is effective at dehumidifying during the summer. However, this can 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 quickly without having time 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 usual smells and what they mean.

Musty, Sour or Mildew

If your mini-split smells musty, sour or like mildew, you might have a mold issue. Have a specialist like AW Heating & Air Conditioning 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 probably dealing with a refrigerant leak. Another surefire clue that you don’t have ample refrigerant is a low concentration of cool air. Reach us at 402-438-7992 for support.

Fish

If your mini-split smells like fish, a couple of things could be wrong. Sometimes this smell means there are electrical issues or that there’s a leak. Regardless, reach us at 402-438-7992 for support.

7. Mini-Split Will Not Power On

If your mini-split will not power on, check the remote first. If the batteries are bad, your mini-split won’t turn on. In most situations, putting in new batteries will solve the situation. If you’re still running into trouble, reach us at 402-438-7992.
