Having mini-split installation done is an excellent approach to solve comfort troubles in your residence. These systems don’t require ductwork to deliver energy-efficient heating and cooling. Like any other home comfort system, they can experience issues occasionally. Here are seven of the most common mini-split issues and how you can fix them.

1. Mini-Split Is Dripping Water or Not Draining 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 expected for a drain line to become clogged with mold, forcing water to back up and leak. Reach May's Heating & Air at 301-690-0397 for assistance and we’ll get your drain unclogged rapidly.

2. Mini-Split Is Making Noise

Mini-splits typically don’t create a lot of noise when they’re on. But there are two instances where they could make 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 happen if your mini-split turns on defrost mode to keep itself from icing up.

You shouldn’t be troubled if you hear these noises as they’re normal. However, if your mini-split keeps going into defrost mode, it’s a symptom that something is wrong, such as insufficient refrigerant, a faulty circuit board or broken sensors. Your May's Heating & Air HVAC technician will be able to locate and resolve the problem quickly.

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 might be the issue. Like we talked about before, icy coils may be the effect of not enough refrigerant, a bad circuit board or broken sensors. Contact us at 301-690-0397 for help.

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 transfer heat and keep your residence pleasant. These leaks must be resolved by a licensed HVAC tech, so contact us at 301-690-0397 for help.

5. Mini-Split Is Not Dehumidifying

Similar to an air conditioner, a mini-split is efficient at dehumidifying during the summer. However, this may be halted by blockages in the condensate drain line. Another reason your mini-split air conditioner may not be dehumidifying properly is if it’s too big. A system that’s oversized will cool down a room too rapidly without having a chance to dehumidify it. Mini-split size is based 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 usual 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 professional like May's Heating & Air check 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 experiencing a refrigerant leak. Another surefire sign that you don’t have sufficient refrigerant is a weak flow of cold air. Call us at 301-690-0397 for support

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 301-690-0397 for assistance.

7. Mini-Split Will Not Power On

If your mini-split will not power on, look at the remote first. If the batteries are bad, your mini-split won’t run. In many instances, putting in fresh batteries will fix the issue. If you’re still experiencing trouble, call us at 301-690-0397.
