7 Common Mini-Split Issues and How to Fix Them

July 12, 2021

Having mini-split installation done is a wise solution for solving comfort issues in your home. These systems don’t need ductwork to give energy-efficient heating and cooling. Similar to any other home comfort system, they can run into problems occasionally. Here are seven of the most frequent mini-split problems and how you can repair 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 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 Jent Mechanical LLC at 937-845-1111 for support and we’ll get your drain unblocked promptly.

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 times where they may produce sounds.

  • Popping or clicking: This can be the result of the plastic housing expanding or contracting while the system is on.
  • Swooshing, crackling or gurgling: This can take place if your mini-split turns on defrost mode to keep itself from icing up.

You shouldn’t be worried if you hear these noises since they’re normal. However, if your mini-split keeps going into defrost mode, it’s a sign that something is off, like not enough refrigerant, a faulty circuit board or malfunctioning sensors. Your Jent Mechanical LLC HVAC professional will be able to find and solve the situation rapidly.

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

If your mini-split is not heating or blowing hot air, ice on the coils might be the problem. Like we mentioned prior to this, iced-over coils can be the effect of low refrigerant, a bad circuit board or defective sensors. Reach us at 937-845-1111 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 needs refrigerant to transfer heat and keep your home cold. These leaks must be resolved by a licensed HVAC professional, so call us at 937-845-1111 for assistance.

5. Mini-Split is Not Dehumidifying

Much like an air conditioner, a mini-split is effective at dehumidifying during the summer. However, this might be halted by clogs 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 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 tell you 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 likely have a mold issue. Have a specialist like Jent Mechanical LLC 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 likely experiencing a refrigerant leak. Another sure sign that you don’t have sufficient refrigerant is a low concentration of chilled air. Call us at 937-845-1111 for help.

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 937-845-1111 for support.

7. Mini-Split Will Not Power On

If your mini-split will not power on, check the remote first. If the batteries are dead, your mini-split won’t switch on. In most instances, putting in new batteries will solve the problem. If you’re still having trouble, contact us at 937-845-1111.
