7 Common Mini-Split Issues and How to Repair Them

July 12, 2021

Having mini-split installation done is a smart way to solve comfort issues in your residence. These systems don’t require ductwork to give energy-efficient heating and cooling. Similar to any other home comfort system, they can experience problems occasionally. Here are seven of the most typical mini-split issues 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 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 spill. Call Brooks Heating and Air Conditioning at 800-COOLING for support and we’ll get your drain unblocked promptly.

2. Mini-Split is Making Noise

Mini-splits usually don’t generate much noise when they’re on. But there are a couple of situations where they could make sounds.

  • Popping or clicking: This can be the result of the plastic housing expanding or contracting while the system is running.
  • Swooshing, crackling or gurgling: This can take place if your mini-split goes into defrost mode to stop itself from freezing over.

You shouldn’t be alarmed if you hear these noises since they’re normal. However, if your mini-split keeps turning on defrost mode, it’s a symptom that something is up, such as not enough refrigerant, a flawed circuit board or malfunctioning sensors. Your Brooks Heating and Air Conditioning HVAC professional will be able to locate and correct the problem fast.

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

If your mini-split is not heating or blowing hot air, frozen coils may be to blame. Like we discussed prior to this, frozen coils may be the consequence of not enough refrigerant, a bad circuit board or malfunctioning sensors. Call us at 800-COOLING for assistance.

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 needs refrigerant to transfer heat and keep your house comfortable. These leaks must be repaired by a licensed HVAC professional, so reach us at 800-COOLING for assistance.

5. Mini-Split is Not Dehumidifying

Like an air conditioner, a mini-split is effective at dehumidifying during the summer. However, this might be stopped by blockages in the condensate drain line. Another reason your mini-split air conditioner may not be dehumidifying very efficientlyis if it’s too large. 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 tell you 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 Brooks Heating and Air Conditioning check and clean the condensate drain and drain line, if needed.

Vinegar

If your mini-split smells like vinegar or has a sweet odor, you’re possibly experiencing a refrigerant leak. Another certain sign that you don’t have sufficient refrigerant is a low concentration of cool air. Call us at 800-COOLING for help.

Fish

If your mini-split smells like fish, a few things could be wrong. In some instances this smell means there are electrical issues or that there’s a leak. Either way, contact us at 800-COOLING 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 out of juice, your mini-split won’t turn on. In most experiences, replacing the batteries will solve the problem. If you’re still running into trouble, reach us at 800-COOLING.
