Having mini-split installation done is a good solution for solving comfort difficulties in your home. These systems don’t require ductwork to give energy-efficient heating and cooling. Similar to any other home comfort system, they can have troubles from time to time. Here are seven of the most common mini-split issues 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 problem with the condensate drain or drain line. It’s expected for a drain line to get clogged with mold, forcing water to back up and drip. Call 1st Choice Heating & Air Conditioning at 949-204-0859 for help and we’ll get your drain unclogged quickly.

2. Mini-Split Is Making Noise

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

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

You shouldn’t be troubled 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 wrong, like not enough refrigerant, a bad circuit board or malfunctioning sensors. Your 1st Choice Heating & Air Conditioning HVAC tech will be able to pinpoint and solve the issue rapidly.

3. Mini-Split Heating Isn’t Working

If your mini-split is not heating or blowing hot air, frozen coils may be the problem. Like we discussed previously, frozen coils might be the consequence of insufficient refrigerant, a faulty circuit board or malfunctioning sensors. Reach us at 949-204-0859 for support.

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

If your mini-split is not cooling or blowing cold air, there could be a refrigerant leak. Your mini-split AC relies on refrigerant to shift heat and keep your house cool. These leaks must be fixed by a licensed HVAC professional, so contact us at 949-204-0859 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 might be interrupted 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 a room too fast without having a chance to dehumidify it. Mini-split size is based on square footage and BTUs.

6. Mini-Split Is Smelly

If your ductless mini-split smells, it’s trying to get your attention 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 might have a mold issue. Have a professional like 1st Choice Heating & Air Conditioning check and clean the condensate drain and drain line, if required.

Vinegar or Chemical Smell

If your mini-split smells like vinegar or has a sweet odor, you’re probably encountering a refrigerant leak. Another surefire hint that you don’t have ample refrigerant is a lack of cool air. Contact us at 949-204-0859 for help

Fish

If your mini-split smells like fish, a few things could be wrong. In some instances this smell means there are electrical issues or there’s a leak. Either way, call us at 949-204-0859 for support.

7. Mini-Split Won’t Turn On

If your mini-split will not power on, examine the remote first. If the batteries are bad, your mini-split won’t switch on. In most instances, putting in fresh batteries will resolve the situation. If you’re still running into trouble, reach us at 949-204-0859.
