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 issues in your residence. These systems don’t require ductwork to provide energy-efficient heating and cooling. Like any other home comfort system, they can run into issues from time to time. Here are seven of the most typical mini-split issues and how you can resolve 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 typical for a drain line to get clogged with mold, force water to back up and drip. Contact Assured Appliance and Heating & Air at 847-306-8990 for help and we’ll get your drain unclogged quickly.

2. Mini-Split is Making Noise

Mini-splits normally don’t generate much noise when they’re on. But there are two times where they might produce sounds.

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

You shouldn’t be worried if you hear these noises since they’re expected. However, if your mini-split keeps switching into defrost mode, it’s a symptom that something is up, such as low refrigerant, a faulty circuit board or malfunctioning sensors. Your Assured Appliance and Heating & Air HVAC pro will be able to find 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, icy coils may be the issue. Like we discussed previously, iced-over coils may be the effect of insufficient refrigerant, a bad circuit board or defective sensors. Call us at 847-306-8990 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 needs refrigerant to move heat and keep your home comfortable. These leaks must be resolved by a licensed HVAC technician, so reach us at 847-306-8990 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 stopped by blockages in the condensate drain line. Another reason your mini-split air conditioner may not be dehumidifying properlyis if it’s too big. A system that’s too large will cool down an area 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 get your attention that something is wrong. Here are five of the most usual smells and what they mean.

Musty, Sour or Mildew

If your mini-split smells musty, sour or like mildew, you may have a mold issue. Have a professional like Assured Appliance and Heating & Air 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 sure sign that you don’t have ample refrigerant is a lack of cold air. Contact us at 847-306-8990 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. Either way, reach us at 847-306-8990 for help.

7. Mini-Split Will Not Power On

If your mini-split will not power on, examine the remote first. If the batteries are out of juice, your mini-split won’t run. In many experiences, replacing the batteries will solve the trouble. If you’re still experiencing trouble, reach us at 847-306-8990.
