Having mini-split installation done is a good solution for solving comfort difficulties in your house. These systems don’t require ductwork to provide energy-efficient heating and cooling. Much like any other home comfort system, they can run into troubles sometimes. Here are seven of the most typical mini-split problems and how you can repair them.

1. Mini-Split Leaks or Can’t Drain 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 be clogged with mold, forcing water to back up and spill. Call B & B Heating & Cooling at 314-325-7552 for assistance and we’ll get your drain unblocked promptly.

2. Mini-Split Makes Constant Noise

Mini-splits normally don’t make much noise when they’re on. But there are two instances where they may produce sounds.

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

You shouldn’t be troubled if you hear these noises since they’re typical. However, if your mini-split keeps switching into defrost mode, it’s a hint that something is off, such as low refrigerant, a faulty circuit board or defective sensors. Your B & B Heating & Cooling HVAC professional will be able to locate and solve the problem quickly.

3. Mini-Split Heating Isn’t Working

If your mini-split is not heating or blowing hot air, frozen coils may be to blame. Like we talked about prior to this, iced-over coils might be the result of insufficient refrigerant, a failing circuit board or broken sensors. Reach us at 314-325-7552 for support.

4. Mini-Split Cooling Isn’t Working

If your mini-split is not cooling or blowing cold air, there may be a refrigerant leak. Your mini-split AC relies on refrigerant to shift heat and keep your residence cold. These leaks must be fixed by a licensed HVAC pro, so reach us at 314-325-7552 for assistance.

5. Mini-Split Drainage Is Clogged

Like 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 very efficiently is if it’s oversized. A system that’s oversized will cool down an area too quickly without having a chance to dehumidify it. Mini-split size is based on square footage and BTUs.

6. Mini-Split Giving Off a Weird Smell

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.

Mold or Mildew

If your mini-split smells musty, sour or like mildew, you likely have a mold issue. Have a specialist like B & B Heating & Cooling check and rinse the condensate drain and drain line, if needed.

Vinegar or Chemical Smell

If your mini-split smells like vinegar or has a sweet odor, you’re likely experiencing a refrigerant leak. Another certain clue that you don’t have enough refrigerant is a lack of chilled 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 are electrical issues or there’s a leak. Either way, call us at 314-325-7552 for help.

7. Mini-Split Isn’t Starting

If your mini-split will not power on, examine the remote first. If the batteries are out of juice, your mini-split won’t turn on. In most instances, putting in new batteries will fix the trouble. If you’re still having trouble, call us at 314-325-7552.
