Having mini-split installation done is a fantastic solution for solving comfort difficulties in your house. These systems don’t need ductwork to provide energy-efficient heating and cooling. Like any other home comfort system, they can have issues sometimes. Here are seven of the most frequent mini-split troubles and how you can repair them.

1. Mini-Split Is Dripping Water or Not Draining Water

If your mini-split is dripping water or not draining water, there could 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 leak. Contact B & B Heating & Cooling at 314-325-7552 for support and we’ll get your drain unclogged promptly.

2. Mini-Split Is Making Noise

Mini-splits usually don’t make much noise when they’re on. But there are a few instances where they might produce 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 take place if your mini-split switches into defrost mode to prevent itself from icing over.

You shouldn’t be troubled if you hear these noises since they’re normal. However, if your mini-split keeps going into defrost mode, it’s a clue that something is wrong, such as low refrigerant, a flawed circuit board or defective sensors. Your B & B Heating & Cooling HVAC technician will be able to pinpoint and correct the situation fast.

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 problem. Like we talked about previously, frozen coils might be the result of insufficient refrigerant, a faulty circuit board or defective sensors. Call us at 314-325-7552 for assistance.

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

If your mini-split is not cooling or blowing cold air, there may be a refrigerant leak. Your mini-split AC needs refrigerant to transfer heat and keep your residence cool. These leaks must be repaired by a licensed HVAC professional, so call us at 314-325-7552 for support.

5. Mini-Split Is Not Dehumidifying

Like an air conditioner, a mini-split is effective at dehumidifying during the summer. However, this could be interrupted by blockages 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 too large will cool down a room too fast without having a moment 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 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 specialist like B & B Heating & Cooling inspect 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 possibly dealing with a refrigerant leak. Another certain sign that you don’t have enough refrigerant is a lack of chilled air. Call us at 314-325-7552 for help

Fish

If your mini-split smells like fish, the following things things could be wrong. In some instances this smell means there are electrical issues or there’s a leak. Either way, call us at 314-325-7552 for support.

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 the majority of instances, replacing the batteries will solve the situation. If you’re still experiencing trouble, reach us at 314-325-7552.
