Having mini-split installation done is a good approach to solve comfort difficulties in your house. These systems don’t have to have ductwork to deliver energy-efficient heating and cooling. Similar to any other home comfort system, they can experience issues sometimes. Here are seven of the most frequent 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 common for a drain line to become clogged with mold, forcing water to back up and drip. Reach Dial One Mears Air Conditioning & Heating Inc at 602-789-3315 for assistance and we’ll get your drain unblocked rapidly.

2. Mini-Split Makes Constant Noise

Mini-splits normally don’t make much noise when they’re operating. But there are two times where they might create sounds.

  • Popping or clicking: This can be because of the plastic housing expanding or contracting while the system is running.
  • Swooshing, crackling or gurgling: This can happen if your mini-split goes into defrost mode to stop itself from icing up.

You shouldn’t be alarmed 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 insufficient refrigerant, a faulty circuit board or defective sensors. Your Dial One Mears Air Conditioning & Heating Inc HVAC technician will be able to find and correct the problem fast.

3. Mini-Split Blows Cold Air in Heating Mode

If your mini-split is not heating or blowing hot air, icy coils could be to blame. Like we talked about prior to this, iced-over coils might be the result of low refrigerant, a failing circuit board or defective sensors. Reach us at 602-789-3315 for support.

4. Mini-Split Is Not Cooling or Blowing Cold Air

If your mini-split is not cooling or blowing cold air, there might be a refrigerant leak. Your mini-split AC relies on refrigerant to move heat and keep your house pleasant. These leaks must be fixed by a licensed HVAC professional, so call us at 602-789-3315 for help.

5. Mini-Split Doesn’t Extract Moisture

Similar to an air conditioner, a mini-split is efficient at dehumidifying during the summer. However, this could be stopped by mold in the condensate drain line. Another reason your mini-split air conditioner may not be dehumidifying properly is if it’s too large. A system that’s oversized will cool down a space too quickly without having a moment 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 might have a mold issue. Have a professional like Dial One Mears Air Conditioning & Heating Inc check 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 ample refrigerant is a lack of cool air. Reach us at 602-789-3315 for assistance

Fish

If your mini-split smells like fish, a few things could be wrong. Sometimes this smell means there is electrical trouble or there’s a leak. Regardless, call us at 602-789-3315 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 bad, your mini-split won’t switch on. In most situations, putting in new batteries will solve the situation. If you’re still having trouble, reach us at 602-789-3315.
