Seven Frequent Mini-Split Problems and How You can Repair Them

Having mini-split installation done is an excellent approach to solve comfort difficulties in your house. These systems don’t have to have 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 issues and how you can fix them.

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

If your mini-split is dripping water or not draining water, there may be an issue with the condensate drain or drain line. It’s expected for a drain line to become clogged with mold, forcing water to back up and drip. Reach Schraer Heating & Air Conditioning at 636-456-5041 for support and we’ll get your drain unblocked rapidly.

2. Mini-Split Is Much Noisier

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

• Popping or clicking: This can be the result of the plastic housing expanding or contracting while the system is operating.

• Swooshing, crackling or gurgling: This can happen if your mini-split switches into defrost mode to keep itself from icing up.

You shouldn’t be worried if you hear these noises because they’re typical. However, if your mini-split keeps turning on defrost mode, it’s a symptom that something is off, such as low refrigerant, a faulty circuit board or broken sensors. Your Schraer Heating & Air Conditioning HVAC technician will be able to pinpoint and solve the problem quickly.

3. Mini-Split Heating Isn’t Working

If your mini-split is not heating or blowing hot air, icy coils might be the problem. Like we mentioned before, icy coils can be the effect of low refrigerant, a failing circuit board or malfunctioning sensors. Call us at 636-456-5041 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 transfer heat and keep your home cool. These leaks must be repaired by a licensed HVAC tech, so contact us at 636-456-5041 for support.

5. Mini-Split Drainage Is Clogged

Much like an air conditioner, a mini-split is effective at dehumidifying during the summer. However, this may 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 oversized. A system that’s too large will cool down an area too fast without having a moment 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 grab your attention that something is wrong. Here are five of the most usual smells and what they mean.

Musty, Sour or Mildew

If your mini-split smells musty, sour or like mildew, you may have a mold issue. Have a professional like Schraer Heating & Air Conditioning check and rinse the condensate drain and drain line, if necessary.

Vinegar

If your mini-split smells like vinegar or has a sweet odor, you’re likely dealing with a refrigerant leak. Another certain sign that you don’t have enough refrigerant is a low concentration of cold air. Call us at 636-456-5041 for help

Fish

If your mini-split smells like fish, a couple of things could be wrong. In some instances this smell means there is electrical trouble or there’s a leak. Nevertheless, contact us at 636-456-5041 for help.

7. Mini-Split Won’t Turn On

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 resolve the issue. If you’re still experiencing trouble, contact us at 636-456-5041.
