Having mini-split installation done is an excellent solution for solving comfort issues in your residence. These systems don’t have to have ductwork to provide energy-efficient heating and cooling. Similar to any other home comfort system, they can experience problems from time to time. Here are seven of the most common mini-split troubles and how you can solve them.

1. Mini-Split Leaks or Can’t 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 typical for a drain line to be clogged with mold, forcing water to back up and leak. Call May's Heating & Air at 301-690-0397 for help and we’ll get your drain unclogged promptly.

2. Mini-Split Is Much Noisier

Mini-splits normally don’t create a lot of noise when they’re running. But there are a couple of situations where they might make sounds.

  • Popping or clicking: This can be due to the plastic housing expanding or contracting while the system is on.
  • Swooshing, crackling or gurgling: This can take place if your mini-split goes into defrost mode to keep itself from freezing over.

You shouldn’t be worried if you hear these noises because they’re normal. However, if your mini-split keeps turning on defrost mode, it’s a symptom that something is wrong, such as insufficient refrigerant, a faulty circuit board or defective sensors. Your May's Heating & Air HVAC professional will be able to pinpoint and solve the issue quickly.

3. Mini-Split Heating Isn’t Working

If your mini-split is not heating or blowing hot air, frozen coils might be the issue. Like we mentioned prior to this, iced-over coils can be the effect of not enough refrigerant, a bad circuit board or defective sensors. Reach us at 301-690-0397 for assistance.

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 uses refrigerant to transfer heat and keep your house pleasant. These leaks must be repaired by a licensed HVAC professional, so reach us at 301-690-0397 for assistance.

5. Mini-Split Drainage Is Clogged

Like an air conditioner, a mini-split does a great job at dehumidifying during the summer. However, this might be interrupted by blockages 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 quickly without having a chance to dehumidify it. Mini-split size is based 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.

Mold or Mildew

If your mini-split smells musty, sour or like mildew, you likely have a mold issue. Have a professional like May's Heating & Air inspect and flush the condensate drain and drain line, if necessary.

Vinegar or Chemical Smell

If your mini-split smells like vinegar or has a sweet odor, you’re possibly dealing with a refrigerant leak. Another surefire clue that you don’t have enough refrigerant is a weak flow of cold air. Call us at 301-690-0397 for help

Fish

If your mini-split smells like fish, the following things things could be wrong. Sometimes this smell means there is electrical trouble or there’s a leak. Either way, contact us at 301-690-0397 for help.

7. Mini-Split Isn’t Starting

If your mini-split will not power on, look at the remote first. If the batteries are dead, your mini-split won’t switch on. In many situations, putting in fresh batteries will solve the issue. If you’re still running into trouble, contact us at 301-690-0397.
