7 Common Mini-Split Troubles and How to Repair Them

July 12, 2021

Having mini-split installation done is a good way to solve comfort difficulties in your house. These systems don’t need ductwork to provide energy-efficient heating and cooling. Like any other home comfort system, they can have troubles occasionally. Here are seven of the most typical mini-split issues 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 might 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 spill. Call Stephen Hurst Pack Heating and Cooling, Inc at 740-474-5940 for help 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 on. 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 running.
  • Swooshing, crackling or gurgling: This can occur if your mini-split switches into defrost mode to prevent itself from icing over.

You shouldn’t be alarmed if you hear these noises as they’re typical. However, if your mini-split keeps turning on defrost mode, it’s a sign that something is up, such as not enough refrigerant, a faulty circuit board or malfunctioning sensors. Your Stephen Hurst Pack Heating and Cooling, Inc HVAC professional 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 might be to blame. Like we talked about prior to this, frozen coils may be the result of insufficient refrigerant, a failing circuit board or defective sensors. Contact us at 740-474-5940 for help.

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

If your mini-split is not cooling or blowing cold air, there may be a refrigerant leak. Your mini-split AC relies on refrigerant to shift heat and keep your house cold. These leaks must be repaired by a licensed HVAC technician, so contact us at 740-474-5940 for assistance.

5. Mini-Split is Not Dehumidifying

Like an air conditioner, a mini-split is effective at dehumidifying during the summer. However, this may be halted by blockages in the condensate drain line. Another reason your mini-split air conditioner may not be dehumidifying very well is 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 calculated 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 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 professional like Stephen Hurst Pack Heating and Cooling, Inc examine 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 likely experiencing a refrigerant leak. Another certain clue that you don’t have enough refrigerant is a weak flow of cold air. Contact us at 740-474-5940 for help.

Fish

If your mini-split smells like fish, the following things things could be wrong. In some instances this smell means there is electrical trouble or that there’s a leak. Regardless, contact us at 740-474-5940 for assistance.

7. Mini-Split Will Not Power On

If your mini-split will not power on, examine the remote first. If the batteries are out of juice, your mini-split won’t turn on. In many experiences, replacing the batteries will solve the problem. If you’re still running into trouble, reach us at 740-474-5940.
