7 Common Mini-Split Problems and How to Fix Them

July 12, 2021

Having mini-split installation done is an excellent solution for solving comfort difficulties in your residence. These systems don’t need ductwork to deliver energy-efficient heating and cooling. Much like any other home comfort system, they can experience issues occasionally. 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 may be a problem with the condensate drain or drain line. It’s common for a drain line to be clogged with mold, force water to back up and spill. Reach True Temp Heating & Air Inc at 706-695-7492 for help and we’ll get your drain unblocked quickly.

2. Mini-Split is Making Noise

Mini-splits normally don’t create a lot of noise when they’re on. But there are a few instances where they could create 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 prevent itself from freezing up.

You shouldn’t be alarmed if you hear these noises as they’re normal. However, if your mini-split keeps turning on defrost mode, it’s a sign that something is up, like not enough refrigerant, a bad circuit board or malfunctioning sensors. Your True Temp Heating & Air Inc HVAC technician will be able to pinpoint and resolve the situation quickly.

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 problem. Like we mentioned previously, iced-over coils may be the effect of not enough refrigerant, a faulty circuit board or malfunctioning sensors. Call us at 706-695-7492 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 uses refrigerant to move heat and keep your home cool. These leaks must be resolved by a licensed HVAC pro, so reach us at 706-695-7492 for assistance.

5. Mini-Split is Not Dehumidifying

Similar to an air conditioner, a mini-split does a great job at dehumidifying during the summer. However, this can be halted by mold in the condensate drain line. Another reason your mini-split air conditioner may not be dehumidifying very well is if it’s oversized. A system that’s too big will cool down a room too fast without having time 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 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 pro like True Temp Heating & Air Inc check 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 likely experiencing a refrigerant leak. Another surefire sign that you don’t have sufficient refrigerant is a low concentration of cold air. Contact us at 706-695-7492 for support.

Fish

If your mini-split smells like fish, a few things could be wrong. In some situations this smell means there is an electrical problem or that there’s a leak. Either way, call us at 706-695-7492 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 switch on. In many experiences, putting in new batteries will resolve the issue. If you’re still experiencing trouble, contact us at 706-695-7492.
