Having mini-split installation done is a fantastic approach to solve comfort difficulties in your home. These systems don’t require ductwork to deliver energy-efficient heating and cooling. Like any other home comfort system, they can run into issues from time to time. Here are seven of the most common mini-split problems and how you can repair them.

1. Mini-Split Is Leaking or Struggling to Drain Water

If your mini-split is dripping water or not draining water, there might be an issue with the condensate drain or drain line. It’s typical for a drain line to become clogged with mold, forcing water to back up and leak. Contact B & B Heating & Cooling at 314-325-7552 for assistance and we’ll get your drain unclogged promptly.

2. Mini-Split Makes Constant Noise

Mini-splits normally don’t make 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 happen if your mini-split turns on defrost mode to prevent itself from icing over.

You shouldn’t be alarmed if you hear these noises since they’re typical. However, if your mini-split keeps turning on defrost mode, it’s a sign that something is wrong, such as insufficient refrigerant, a bad circuit board or malfunctioning sensors. Your B & B Heating & Cooling HVAC professional will be able to locate and resolve the problem rapidly.

3. Mini-Split Blows Cold Air in Heating Mode

If your mini-split is not heating or blowing hot air, ice on the coils could be to blame. Like we talked about before, frozen coils could be the consequence of insufficient refrigerant, a failing circuit board or defective sensors. Contact us at 314-325-7552 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 needs refrigerant to move heat and keep your house pleasant. These leaks must be fixed by a licensed HVAC professional, so contact us at 314-325-7552 for help.

5. Mini-Split Drainage Is Clogged

Similar to an air conditioner, a mini-split does a great job 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 very effectively is if it’s too large. A system that’s too large will cool down an area too rapidly without having a chance to dehumidify it. Mini-split size is calculated on square footage and BTUs.

6. Mini-Split Produces Strange Odors

If your ductless mini-split smells, it’s trying to tell you that something is wrong. Here are five of the most common 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 pro like B & B Heating & Cooling examine 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 likely encountering a refrigerant leak. Another surefire clue that you don’t have ample refrigerant is a low concentration of cool air. Call us at 314-325-7552 for assistance

Fish

If your mini-split smells like fish, a couple of things could be wrong. In some situations this smell means there is electrical trouble or there’s a leak. Nevertheless, reach us at 314-325-7552 for assistance.

7. Mini-Split Isn’t Starting

If your mini-split will not power on, check the remote first. If the batteries are dead, your mini-split won’t switch on. In many instances, putting in fresh batteries will resolve the situation. If you’re still experiencing trouble, call us at 314-325-7552.
