7 Common Mini-Split Problems and How to Repair Them

July 12, 2021

Having mini-split installation done is a smart solution for solving comfort issues in your house. These systems don’t have to have ductwork to provide energy-efficient heating and cooling. Much like any other home comfort system, they can experience issues from time to time. Here are seven of the most common mini-split problems 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 might be a situation with the condensate drain or drain line. It’s typical for a drain line to become clogged with mold, force water to back up and spill. Call Edington Heating & Cooling Inc at 937-558-9478 for help and we’ll get your drain unplugged promptly.

2. Mini-Split is Making Noise

Mini-splits typically don’t make much noise when they’re running. But there are two instances 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 happen if your mini-split goes into defrost mode to stop itself from icing over.

You shouldn’t be troubled if you hear these noises as they’re expected. However, if your mini-split keeps switching into defrost mode, it’s a hint that something is off, such as insufficient refrigerant, a bad circuit board or defective sensors. Your Edington Heating & Cooling Inc HVAC professional will be able to find and correct the situation quickly.

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

If your mini-split is not heating or blowing hot air, frozen coils might be to blame. Like we mentioned before, frozen coils might be the effect of not enough refrigerant, a failing circuit board or malfunctioning sensors. Contact us at 937-558-9478 for assistance.

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 transfer heat and keep your home comfortable. These leaks must be repaired by a licensed HVAC technician, so reach us at 937-558-9478 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 interrupted by clogs 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 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 could have a mold issue. Have a pro like Edington Heating & Cooling Inc inspect and rinse the condensate drain and drain line, if needed.

Vinegar

If your mini-split smells like vinegar or has a sweet odor, you’re probably encountering a refrigerant leak. Another surefire sign that you don’t have enough refrigerant is a weak flow of cool air. Reach us at 937-558-9478 for help.

Fish

If your mini-split smells like fish, the following things things could be wrong. In some instances this smell means there are electrical issues or that there’s a leak. Regardless, contact us at 937-558-9478 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 bad, your mini-split won’t switch on. In most situations, replacing the batteries will solve the issue. If you’re still experiencing trouble, reach us at 937-558-9478.
