7 Common Mini-Split Troubles and How to Fix Them

July 12, 2021

Having mini-split installation done is a great solution for solving comfort troubles in your home. These systems don’t need ductwork to deliver energy-efficient heating and cooling. Similar to any other home comfort system, they can run into problems from time to time. Here are seven of the most frequent mini-split issues and how you can fix 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 typical for a drain line to become clogged with mold, force water to back up and spill. Contact GV Heating & Air at 763-535-2000 for support 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 running. But there are a few situations where they could 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 occur if your mini-split switches into defrost mode to stop itself from freezing over.

You shouldn’t be worried if you hear these noises because they’re typical. However, if your mini-split keeps going into defrost mode, it’s a sign that something is wrong, including insufficient refrigerant, a flawed circuit board or broken sensors. Your GV Heating & Air HVAC pro will be able to pinpoint and correct the situation 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 issue. Like we discussed prior to this, icy coils could be the consequence of low refrigerant, a bad circuit board or malfunctioning sensors. Reach us at 763-535-2000 for support.

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 move heat and keep your residence pleasant. These leaks must be repaired by a licensed HVAC professional, so call us at 763-535-2000 for assistance.

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 stopped by mold in the condensate drain line. Another reason your mini-split air conditioner may not be dehumidifying very effectivelyis if it’s oversized. A system that’s too big will cool down a room too fast 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 typical 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 professional like GV Heating & Air 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 possibly experiencing a refrigerant leak. Another sure clue that you don’t have sufficient refrigerant is a low concentration of cold air. Contact us at 763-535-2000 for help.

Fish

If your mini-split smells like fish, a few things could be wrong. Sometimes this smell means there are electrical issues or that there’s a leak. Regardless, reach us at 763-535-2000 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 many situations, putting in fresh batteries will fix the issue. If you’re still experiencing trouble, call us at 763-535-2000.
