7 Common Mini-Split Troubles and How to Repair Them

July 12, 2021

Having mini-split installation done is a wise solution for solving comfort problems in your home. These systems don’t have to have ductwork to deliver energy-efficient heating and cooling. Similar to any other home comfort system, they can have problems sometimes. Here are seven of the most typical mini-split problems 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 could be a situation 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 leak. Call Dave's Diversified Services at 540-369-3971 for help and we’ll get your drain unclogged promptly.

2. Mini-Split is Making Noise

Mini-splits normally don’t generate much noise when they’re operating. But there are two situations where they might make 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 switches into defrost mode to stop itself from icing up.

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 clue that something is off, such as not enough refrigerant, a faulty circuit board or malfunctioning sensors. Your Dave's Diversified Services 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, frozen coils might be the issue. Like we mentioned prior to this, icy coils might be the effect of low refrigerant, a faulty circuit board or malfunctioning sensors. Call us at 540-369-3971 for help.

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 needs refrigerant to shift heat and keep your home cool. These leaks must be resolved by a licensed HVAC pro, so contact us at 540-369-3971 for help.

5. Mini-Split is Not Dehumidifying

Like an air conditioner, a mini-split is efficient at dehumidifying during the summer. However, this could be interrupted 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 large will cool down a space too rapidly without having a moment to dehumidify it. Mini-split size is calculated 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 pro like Dave's Diversified Services inspect and rinse 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 hint that you don’t have enough refrigerant is a weak flow of cold air. Contact us at 540-369-3971 for support.

Fish

If your mini-split smells like fish, a couple of things could be wrong. Sometimes this smell means there are electrical issues or that there’s a leak. Regardless, call us at 540-369-3971 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 many experiences, putting in fresh batteries will fix the problem. If you’re still experiencing trouble, contact us at 540-369-3971.
