Having mini-split installation done is a good 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 have problems occasionally. Here are seven of the most common mini-split problems 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 might be a situation with the condensate drain or drain line. It’s expected for a drain line to get clogged with mold, forcing water to back up and drip. Reach Contra Costa Heating & AC at 510-343-9841 for help and we’ll get your drain unplugged promptly.

2. Mini-Split Is Making Noise

Mini-splits normally don’t create a lot of noise when they’re running. But there are two situations where they might produce sounds.

  • Popping or clicking: This can be the result of the plastic housing expanding or contracting while the system is operating.
  • Swooshing, crackling or gurgling: This can take place if your mini-split switches into defrost mode to prevent itself from freezing over.

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 hint that something is up, such as not enough refrigerant, a bad circuit board or defective sensors. Your Contra Costa Heating & AC HVAC professional will be able to find and resolve the problem 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 may be the issue. Like we discussed previously, icy coils might be the result of insufficient refrigerant, a faulty circuit board or malfunctioning sensors. Call us at 510-343-9841 for help.

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 house cold. These leaks must be resolved by a licensed HVAC pro, so contact us at 510-343-9841 for support.

5. Mini-Split Is Not Dehumidifying

Similar to an air conditioner, a mini-split does a great job at dehumidifying during the summer. However, this may be stopped by clogs in the condensate drain line. Another reason your mini-split air conditioner may not be dehumidifying very effectively is if it’s oversized. A system that’s too large will cool down an area too quickly without having a chance 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 typical 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 professional like Contra Costa Heating & AC check 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 encountering a refrigerant leak. Another surefire clue that you don’t have sufficient refrigerant is a weak flow of cold air. Contact us at 510-343-9841 for help

Fish

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

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 many situations, putting in new batteries will solve the situation. If you’re still running into trouble, call us at 510-343-9841.
