7 Common Mini-Split Troubles and How to Fix Them

July 12, 2021

Having mini-split installation done is an excellent approach to solve comfort difficulties in your home. These systems don’t need ductwork to provide energy-efficient heating and cooling. Much like any other home comfort system, they can experience problems from time to time. 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 may be a problem with the condensate drain or drain line. It’s expected for a drain line to be clogged with mold, force water to back up and spill. Contact Allstar Heating & Air Conditioning at 805-242-9638 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 running. But there are a couple of times where they might produce sounds.

  • Popping or clicking: This can be because of the plastic housing expanding or contracting while the system is on.
  • Swooshing, crackling or gurgling: This can happen if your mini-split turns on defrost mode to stop itself from icing over.

You shouldn’t be worried if you hear these noises because they’re typical. However, if your mini-split keeps switching into defrost mode, it’s a sign that something is off, including not enough refrigerant, a bad circuit board or broken sensors. Your Allstar Heating & Air Conditioning HVAC pro will be able to find and solve the problem rapidly.

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 the problem. Like we mentioned prior to this, iced-over coils could be the result of insufficient refrigerant, a faulty circuit board or broken sensors. Call us at 805-242-9638 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 shift heat and keep your residence comfortable. These leaks must be fixed by a licensed HVAC professional, so contact us at 805-242-9638 for support.

5. Mini-Split is Not Dehumidifying

Similar to an air conditioner, a mini-split is efficient at dehumidifying during the summer. However, this may be interrupted by mold 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 a space too quickly without having time 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 grab 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 could have a mold issue. Have a professional like Allstar Heating & Air Conditioning inspect 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 possibly encountering a refrigerant leak. Another surefire sign that you don’t have sufficient refrigerant is a lack of cold air. Reach us at 805-242-9638 for assistance.

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. Regardless, reach us at 805-242-9638 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 dead, your mini-split won’t switch on. In most instances, putting in fresh batteries will fix the situation. If you’re still experiencing trouble, call us at 805-242-9638.
