7 Common Mini-Split Issues and How to Fix Them

July 12, 2021

Having mini-split installation done is a fantastic way to solve comfort troubles in your residence. These systems don’t require ductwork to give energy-efficient heating and cooling. Similar to any other home comfort system, they can experience issues sometimes. Here are seven of the most typical mini-split issues 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 may be a situation with the condensate drain or drain line. It’s typical for a drain line to get clogged with mold, force water to back up and leak. Contact Bon Air Service Company at 972-332-1028 for support and we’ll get your drain unplugged quickly.

2. Mini-Split is Making Noise

Mini-splits normally don’t generate much noise when they’re on. But there are a couple of situations where they may produce sounds.

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

You shouldn’t be alarmed if you hear these noises as they’re expected. However, if your mini-split keeps switching into defrost mode, it’s a clue that something is off, including not enough refrigerant, a faulty circuit board or malfunctioning sensors. Your Bon Air Service Company HVAC pro will be able to pinpoint and solve the situation rapidly.

3. Mini-Split is Not Heating or Blowing Hot Air

If your mini-split is not heating or blowing hot air, icy coils might be the issue. Like we talked about previously, icy coils could be the consequence of not enough refrigerant, a bad circuit board or broken sensors. Call us at 972-332-1028 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 uses refrigerant to move heat and keep your house pleasant. These leaks must be resolved by a licensed HVAC professional, so contact us at 972-332-1028 for help.

5. Mini-Split is Not Dehumidifying

Like an air conditioner, a mini-split is effective at dehumidifying during the summer. However, this may be halted by clogs in the condensate drain line. Another reason your mini-split air conditioner may not be dehumidifying very effectivelyis if it’s too large. A system that’s too large will cool down an area too rapidly without having a chance 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 grab your attention 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 may have a mold issue. Have a professional like Bon Air Service Company examine 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 probably dealing with a refrigerant leak. Another certain hint that you don’t have ample refrigerant is a lack of cool air. Call us at 972-332-1028 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 that there’s a leak. Regardless, contact us at 972-332-1028 for assistance.

7. Mini-Split Will Not Power On

If your mini-split will not power on, check the remote first. If the batteries are bad, your mini-split won’t turn on. In most instances, putting in new batteries will resolve the trouble. If you’re still having trouble, call us at 972-332-1028.
