Having mini-split installation done is a fantastic solution for solving comfort issues in your residence. These systems don’t need ductwork to provide energy-efficient heating and cooling. Like any other home comfort system, they can have troubles sometimes. Here are seven of the most typical mini-split problems and how you can fix 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 be clogged with mold, forcing water to back up and drip. Reach Three Rivers Heating & Cooling at 503-213-4433 for support and we’ll get your drain unblocked promptly.

2. Mini-Split Is Making Noise

Mini-splits typically don’t create a lot of noise when they’re running. But there are a few times where they may create sounds.

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

You shouldn’t be worried if you hear these noises because they’re expected. However, if your mini-split keeps going into defrost mode, it’s a symptom that something is off, such as low refrigerant, a faulty circuit board or malfunctioning sensors. Your Three Rivers Heating & Cooling HVAC professional will be able to locate and correct 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 might be the problem. Like we talked about prior to this, iced-over coils could be the result of not enough refrigerant, a failing circuit board or malfunctioning sensors. Call us at 503-213-4433 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 transfer heat and keep your house pleasant. These leaks must be resolved by a licensed HVAC professional, so contact us at 503-213-4433 for assistance.

5. Mini-Split Is Not Dehumidifying

Much like an air conditioner, a mini-split is efficient at dehumidifying during the summer. However, this could be stopped by clogs in the condensate drain line. Another reason your mini-split air conditioner may not be dehumidifying properly is if it’s too big. A system that’s too large will cool down an area too quickly without having time 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 typical 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 Three Rivers Heating & Cooling check and clean the condensate drain and drain line, if needed.

Vinegar

If your mini-split smells like vinegar or has a sweet odor, you’re likely dealing with a refrigerant leak. Another certain clue that you don’t have ample refrigerant is a weak flow of chilled air. Reach us at 503-213-4433 for support

Fish

If your mini-split smells like fish, the following things things could be wrong. Sometimes this smell means there are electrical issues or there’s a leak. Either way, reach us at 503-213-4433 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 out of juice, your mini-split won’t turn on. In many experiences, putting in new batteries will resolve the issue. If you’re still running into trouble, reach us at 503-213-4433.
