7 Common Mini-Split Problems and How to Repair Them

July 12, 2021

Having mini-split installation done is an excellent solution for solving comfort problems in your house. These systems don’t need ductwork to deliver energy-efficient heating and cooling. Much like any other home comfort system, they can have troubles from time to time. Here are seven of the most frequent mini-split issues 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 could 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 drip. Call B&D Air Conditioning at 928-432-6018 for support and we’ll get your drain unclogged promptly.

2. Mini-Split is Making Noise

Mini-splits normally don’t create a lot of noise when they’re on. But there are two 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 occur if your mini-split switches into defrost mode to keep itself from freezing up.

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 wrong, such as low refrigerant, a flawed circuit board or broken sensors. Your B&D Air Conditioning HVAC professional will be able to pinpoint and correct the issue quickly.

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 issue. Like we mentioned before, frozen coils may be the consequence of low refrigerant, a failing circuit board or defective sensors. Call us at 928-432-6018 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 relies on refrigerant to shift heat and keep your home cold. These leaks must be resolved by a licensed HVAC pro, so call us at 928-432-6018 for help.

5. Mini-Split is Not Dehumidifying

Like an air conditioner, a mini-split is efficient at dehumidifying during the summer. However, this might be interrupted by blockages in the condensate drain line. Another reason your mini-split air conditioner may not be dehumidifying very well is if it’s too large. A system that’s oversized will cool down a room too fast 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 usual 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 specialist like B&D Air Conditioning inspect and rinse 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 certain sign that you don’t have enough refrigerant is a weak flow of cold air. Reach us at 928-432-6018 for support.

Fish

If your mini-split smells like fish, the following things things could be wrong. In some instances this smell means there is an electrical problem or that there’s a leak. Nevertheless, reach us at 928-432-6018 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 out of juice, your mini-split won’t switch on. In many experiences, putting in new batteries will solve the problem. If you’re still having trouble, reach us at 928-432-6018.
