7 Common Mini-Split Troubles and How to Resolve Them

July 12, 2021

Having mini-split installation done is a fantastic approach to solve comfort troubles in your residence. These systems don’t need ductwork to deliver energy-efficient heating and cooling. Like any other home comfort system, they can run into issues sometimes. Here are seven of the most common mini-split troubles and how you can resolve 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 common for a drain line to become clogged with mold, force water to back up and leak. Reach Halverson Brothers Inc at 715-352-4052 for support and we’ll get your drain unplugged promptly.

2. Mini-Split is Making Noise

Mini-splits normally don’t make much noise when they’re running. But there are two times where they may produce sounds.

  • Popping or clicking: This can be due to the plastic housing expanding or contracting while the system is running.
  • Swooshing, crackling or gurgling: This can occur if your mini-split goes into defrost mode to prevent itself from freezing up.

You shouldn’t be worried if you hear these noises as they’re normal. However, if your mini-split keeps switching into defrost mode, it’s a clue that something is wrong, such as insufficient refrigerant, a flawed circuit board or malfunctioning sensors. Your Halverson Brothers Inc HVAC technician will be able to find and correct the issue quickly.

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

If your mini-split is not heating or blowing hot air, ice on the coils might be to blame. Like we talked about before, icy coils may be the result of low refrigerant, a failing circuit board or defective sensors. Reach us at 715-352-4052 for assistance.

4. Mini-Split is Not Cooling or Blowing Cold Air

If your mini-split is not cooling or blowing cold air, there may be a refrigerant leak. Your mini-split AC relies on refrigerant to transfer heat and keep your house cold. These leaks must be resolved by a licensed HVAC technician, so contact us at 715-352-4052 for assistance.

5. Mini-Split is Not Dehumidifying

Like an air conditioner, a mini-split is efficient at dehumidifying during the summer. However, this can be halted by mold in the condensate drain line. Another reason your mini-split air conditioner may not be dehumidifying very efficientlyis if it’s oversized. A system that’s too large will cool down a space too rapidly 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 could have a mold issue. Have a professional like Halverson Brothers Inc inspect and flush the condensate drain and drain line, if necessary.

Vinegar

If your mini-split smells like vinegar or has a sweet odor, you’re likely dealing with a refrigerant leak. Another surefire sign that you don’t have ample refrigerant is a low concentration of cool air. Reach us at 715-352-4052 for support.

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. Nevertheless, contact us at 715-352-4052 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 bad, your mini-split won’t switch on. In the majority of situations, replacing the batteries will solve the issue. If you’re still running into trouble, call us at 715-352-4052.
