7 Common Mini-Split Troubles and How to Fix Them

July 12, 2021

Having mini-split installation done is a fantastic way to solve comfort problems in your residence. These systems don’t have to have ductwork to deliver energy-efficient heating and cooling. Like any other home comfort system, they can experience troubles sometimes. Here are seven of the most common mini-split troubles 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 typical for a drain line to be clogged with mold, force water to back up and drip. Reach Contra Costa Heating & AC at 510-343-9841 for support and we’ll get your drain unblocked promptly.

2. Mini-Split is Making Noise

Mini-splits normally don’t generate much noise when they’re running. But there are a couple of instances where they could produce sounds.

  • Popping or clicking: This can be due to the plastic housing expanding or contracting while the system is operating.
  • Swooshing, crackling or gurgling: This can occur if your mini-split switches into defrost mode to stop itself from icing over.

You shouldn’t be alarmed if you hear these noises as they’re normal. However, if your mini-split keeps turning on defrost mode, it’s a hint that something is wrong, such as low refrigerant, a flawed circuit board or defective sensors. Your Contra Costa Heating & AC HVAC pro will be able to pinpoint 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 could be to blame. Like we talked about before, icy coils might be the result of low refrigerant, a faulty circuit board or defective sensors. Reach us at 510-343-9841 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 shift heat and keep your residence cool. These leaks must be repaired by a licensed HVAC professional, so call us at 510-343-9841 for support.

5. Mini-Split is Not Dehumidifying

Similar to an air conditioner, a mini-split is efficient 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 efficientlyis if it’s too big. A system that’s too large will cool down a room too fast without having a moment to dehumidify it. Mini-split size is planned 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 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 professional like Contra Costa Heating & AC examine and flush the condensate drain and drain line, if required.

Vinegar

If your mini-split smells like vinegar or has a sweet odor, you’re possibly dealing with a refrigerant leak. Another surefire clue that you don’t have sufficient refrigerant is a lack of chilled air. Reach us at 510-343-9841 for assistance.

Fish

If your mini-split smells like fish, a couple of things could be wrong. Sometimes this smell means there is electrical trouble or that there’s a leak. Regardless, call us at 510-343-9841 for help.

7. Mini-Split Will Not Power On

If your mini-split will not power on, look at the remote first. If the batteries are dead, your mini-split won’t turn on. In the majority of experiences, replacing the batteries will resolve the trouble. If you’re still running into trouble, reach us at 510-343-9841.
