7 Common Mini-Split Problems and How to Resolve 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 provide energy-efficient heating and cooling. Similar to any other home comfort system, they can experience troubles sometimes. Here are seven of the most frequent 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 an issue with the condensate drain or drain line. It’s expected for a drain line to get clogged with mold, force water to back up and leak. Call Vogts Heating & Air at 208-621-0129 for support and we’ll get your drain unblocked rapidly.

2. Mini-Split is Making Noise

Mini-splits normally don’t create a lot of noise when they’re running. But there are a few times where they could make sounds.

  • Popping or clicking: This can be due to 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 keep itself from icing up.

You shouldn’t be worried if you hear these noises since they’re typical. However, if your mini-split keeps switching into defrost mode, it’s a hint that something is up, such as insufficient refrigerant, a bad circuit board or defective sensors. Your Vogts Heating & Air HVAC professional will be able to locate and solve 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 the issue. Like we talked about previously, frozen coils may be the result of not enough refrigerant, a faulty circuit board or defective sensors. Call us at 208-621-0129 for support.

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 uses refrigerant to shift heat and keep your residence cold. These leaks must be resolved by a licensed HVAC technician, so contact us at 208-621-0129 for assistance.

5. Mini-Split is Not Dehumidifying

Like an air conditioner, a mini-split does a great job at dehumidifying during the summer. However, this might be halted by blockages in the condensate drain line. Another reason your mini-split air conditioner may not be dehumidifying very effectivelyis if it’s too large. A system that’s oversized will cool down a room 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 usual smells and what they mean.

Musty, Sour or Mildew

If your mini-split smells musty, sour or like mildew, you likely have a mold issue. Have a specialist like Vogts Heating & Air inspect and clean the condensate drain and drain line, if necessary.

Vinegar

If your mini-split smells like vinegar or has a sweet odor, you’re probably dealing with a refrigerant leak. Another sure hint that you don’t have ample refrigerant is a low concentration of cold air. Reach us at 208-621-0129 for assistance.

Fish

If your mini-split smells like fish, the following things things could be wrong. Sometimes this smell means there is an electrical problem or that there’s a leak. Either way, contact us at 208-621-0129 for assistance.

7. Mini-Split Will Not Power On

If your mini-split will not power on, examine the remote first. If the batteries are bad, your mini-split won’t switch on. In most situations, putting in fresh batteries will resolve the situation. If you’re still having trouble, call us at 208-621-0129.
