7 Common Mini-Split Issues and How to Repair Them

July 12, 2021

Having mini-split installation done is a fantastic way to solve comfort issues in your home. These systems don’t require ductwork to give energy-efficient heating and cooling. Similar to any other home comfort system, they can run into troubles sometimes. Here are seven of the most typical mini-split troubles and how you can solve 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 problem with the condensate drain or drain line. It’s typical for a drain line to become clogged with mold, force water to back up and spill. Call Farnell Mechanical, Inc. at 334-245-4748 for help and we’ll get your drain unclogged promptly.

2. Mini-Split is Making Noise

Mini-splits typically don’t create a lot of noise when they’re running. But there are two instances where they may make 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 take place if your mini-split turns on defrost mode to prevent itself from freezing up.

You shouldn’t be alarmed if you hear these noises because they’re normal. However, if your mini-split keeps switching into defrost mode, it’s a hint that something is up, including insufficient refrigerant, a faulty circuit board or defective sensors. Your Farnell Mechanical, Inc. HVAC professional 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 the problem. Like we mentioned previously, frozen coils can be the consequence of not enough refrigerant, a failing circuit board or malfunctioning sensors. Call us at 334-245-4748 for help.

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 relies on refrigerant to transfer heat and keep your house cool. These leaks must be repaired by a licensed HVAC tech, so call us at 334-245-4748 for support.

5. Mini-Split is Not Dehumidifying

Similar to an air conditioner, a mini-split does a great job at dehumidifying during the summer. However, this can 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 oversized. A system that’s too large will cool down an area too rapidly without having a moment 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 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 could have a mold issue. Have a professional like Farnell Mechanical, Inc. check and clean the condensate drain and drain line, if required.

Vinegar

If your mini-split smells like vinegar or has a sweet odor, you’re possibly experiencing a refrigerant leak. Another sure sign that you don’t have ample refrigerant is a weak flow of cold air. Contact us at 334-245-4748 for assistance.

Fish

If your mini-split smells like fish, the following things things could be wrong. In some instances this smell means there is an electrical problem or that there’s a leak. Either way, contact us at 334-245-4748 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 bad, your mini-split won’t switch on. In the majority of instances, replacing the batteries will resolve the situation. If you’re still having trouble, contact us at 334-245-4748.
