7 Common Mini-Split Troubles and How to Repair Them

July 12, 2021

Having mini-split installation done is a fantastic solution for solving comfort troubles 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 troubles sometimes. Here are seven of the most common mini-split issues 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 common for a drain line to become clogged with mold, force water to back up and spill. Contact Goode Bros AC & Heating at (833)-466-3322 for help and we’ll get your drain unclogged quickly.

2. Mini-Split is Making Noise

Mini-splits usually don’t create a lot of noise when they’re on. But there are a couple of times where they may 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 turns on defrost mode to prevent itself from freezing up.

You shouldn’t be troubled if you hear these noises as they’re normal. However, if your mini-split keeps going into defrost mode, it’s a sign that something is wrong, like insufficient refrigerant, a flawed circuit board or malfunctioning sensors. Your Goode Bros AC & Heating HVAC technician will be able to locate 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, ice on the coils might be to blame. Like we discussed previously, frozen coils might be the effect of insufficient refrigerant, a bad circuit board or broken sensors. Reach us at (833)-466-3322 for assistance.

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 uses refrigerant to move heat and keep your residence cold. These leaks must be fixed by a licensed HVAC technician, so call us at (833)-466-3322 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 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 oversized will cool down a room too rapidly without having a moment to dehumidify it. Mini-split size is planned 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 common 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 pro like Goode Bros AC & Heating examine and flush the condensate drain and drain line, if necessary.

Vinegar

If your mini-split smells like vinegar or has a sweet odor, you’re probably encountering a refrigerant leak. Another certain clue that you don’t have ample refrigerant is a low concentration of cool air. Call us at (833)-466-3322 for support.

Fish

If your mini-split smells like fish, a couple of things could be wrong. In some situations this smell means there is electrical trouble or that there’s a leak. Regardless, call us at (833)-466-3322 for help.

7. Mini-Split Will Not Power On

If your mini-split will not power on, look at the remote first. If the batteries are bad, your mini-split won’t switch on. In most experiences, putting in new batteries will fix the issue. If you’re still having trouble, reach us at (833)-466-3322.
