7 Common Mini-Split Issues and How to Fix Them

July 12, 2021

Having mini-split installation done is a good solution for solving comfort problems in your residence. These systems don’t need ductwork to give energy-efficient heating and cooling. Like any other home comfort system, they can run into problems sometimes. Here are seven of the most frequent 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 situation 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. Reach Controlled Comfort HVAC Inc at 224-412-8308 for help and we’ll get your drain unblocked rapidly.

2. Mini-Split is Making Noise

Mini-splits usually don’t make much noise when they’re operating. But there are a few times where they could produce sounds.

  • Popping or clicking: This can be because of the plastic housing expanding or contracting while the system is running.
  • 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 worried if you hear these noises because they’re expected. However, if your mini-split keeps turning on defrost mode, it’s a symptom that something is off, like not enough refrigerant, a flawed circuit board or defective sensors. Your Controlled Comfort HVAC Inc HVAC professional will be able to find and solve the problem quickly.

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

If your mini-split is not heating or blowing hot air, icy coils could be the problem. Like we mentioned before, icy coils could be the result of low refrigerant, a failing circuit board or malfunctioning sensors. Contact us at 224-412-8308 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 shift heat and keep your residence pleasant. These leaks must be resolved by a licensed HVAC technician, so contact us at 224-412-8308 for support.

5. Mini-Split is Not Dehumidifying

Similar to an air conditioner, a mini-split is effective at dehumidifying during the summer. However, this could be halted by blockages 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 oversized will cool down a space too quickly 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 get 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 may have a mold issue. Have a specialist like Controlled Comfort HVAC Inc examine and clean the condensate drain and drain line, if necessary.

Vinegar

If your mini-split smells like vinegar or has a sweet odor, you’re possibly dealing with a refrigerant leak. Another sure sign that you don’t have sufficient refrigerant is a low concentration of cold air. Call us at 224-412-8308 for assistance.

Fish

If your mini-split smells like fish, a couple of things could be wrong. Sometimes this smell means there is an electrical problem or that there’s a leak. Either way, reach us at 224-412-8308 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 out of juice, your mini-split won’t turn on. In most instances, putting in fresh batteries will solve the issue. If you’re still running into trouble, reach us at 224-412-8308.
