7 Common Mini-Split Problems and How to Repair Them

July 12, 2021

Having mini-split installation done is an excellent way to solve comfort difficulties in your house. These systems don’t have to have ductwork to give energy-efficient heating and cooling. Like any other home comfort system, they can experience problems sometimes. Here are seven of the most typical mini-split troubles 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 might be a situation with the condensate drain or drain line. It’s typical for a drain line to be clogged with mold, force water to back up and drip. Call Dial One Mears Air Conditioning & Heating Inc at 602-832-7808 for assistance and we’ll get your drain unplugged rapidly.

2. Mini-Split is Making Noise

Mini-splits normally don’t generate much noise when they’re running. But there are two instances where they might create 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 occur if your mini-split switches into defrost mode to stop itself from freezing up.

You shouldn’t be worried if you hear these noises since they’re typical. However, if your mini-split keeps going into defrost mode, it’s a hint that something is off, including low refrigerant, a bad circuit board or defective sensors. Your Dial One Mears Air Conditioning & Heating Inc HVAC technician will be able to locate and resolve the issue quickly.

3. Mini-Split is Not Heating or Blowing Hot Air

If your mini-split is not heating or blowing hot air, frozen coils could be to blame. Like we mentioned before, icy coils could be the result of insufficient refrigerant, a faulty circuit board or malfunctioning sensors. Reach us at 602-832-7808 for help.

4. Mini-Split is Not Cooling or Blowing Cold Air

If your mini-split is not cooling or blowing cold air, there could be a refrigerant leak. Your mini-split AC relies on refrigerant to shift heat and keep your house cold. These leaks must be repaired by a licensed HVAC pro, so reach us at 602-832-7808 for help.

5. Mini-Split is Not Dehumidifying

Much like an air conditioner, a mini-split is effective at dehumidifying during the summer. However, this may be stopped by mold in the condensate drain line. Another reason your mini-split air conditioner may not be dehumidifying properlyis if it’s oversized. A system that’s oversized will cool down a room too quickly without having time 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 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 professional like Dial One Mears Air Conditioning & Heating Inc check and rinse the condensate drain and drain line, if necessary.

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 ample refrigerant is a lack of cool air. Call us at 602-832-7808 for support.

Fish

If your mini-split smells like fish, a couple of things could be wrong. In some instances this smell means there are electrical issues or that there’s a leak. Nevertheless, reach us at 602-832-7808 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 many experiences, putting in fresh batteries will fix the issue. If you’re still experiencing trouble, reach us at 602-832-7808.
