7 Common Mini-Split Issues and How to Repair Them

July 12, 2021

Having mini-split installation done is a wise solution for solving comfort difficulties in your house. These systems don’t have to have ductwork to give energy-efficient heating and cooling. Similar to any other home comfort system, they can experience issues from time to time. Here are seven of the most common mini-split problems 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 could be an issue 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 drip. Contact Brogan Heating & AC Inc at 507-218-0088 for help and we’ll get your drain unblocked rapidly.

2. Mini-Split is Making Noise

Mini-splits normally don’t generate much noise when they’re operating. But there are two times where they might create sounds.

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

You shouldn’t be worried 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 off, such as low refrigerant, a faulty circuit board or malfunctioning sensors. Your Brogan Heating & AC Inc HVAC pro will be able to locate and resolve the issue fast.

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 to blame. Like we discussed previously, iced-over coils might be the effect of not enough refrigerant, a failing circuit board or malfunctioning sensors. Call us at 507-218-0088 for support.

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 needs refrigerant to transfer heat and keep your house pleasant. These leaks must be repaired by a licensed HVAC professional, so contact us at 507-218-0088 for assistance.

5. Mini-Split is Not Dehumidifying

Much like an air conditioner, a mini-split does a great job at dehumidifying during the summer. However, this might be stopped by clogs 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 big will cool down a room too quickly without having a chance 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 likely have a mold issue. Have a pro like Brogan Heating & AC Inc 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 sure clue that you don’t have enough refrigerant is a low concentration of chilled air. Call us at 507-218-0088 for support.

Fish

If your mini-split smells like fish, a few things could be wrong. Sometimes this smell means there is an electrical problem or that there’s a leak. Nevertheless, call us at 507-218-0088 for support.

7. Mini-Split Will Not Power On

If your mini-split will not power on, look at the remote first. If the batteries are dead, your mini-split won’t run. In the majority of situations, putting in fresh batteries will fix the issue. If you’re still experiencing trouble, call us at 507-218-0088.
