7 Common Mini-Split Troubles and How to Fix Them

July 12, 2021

Having mini-split installation done is a good solution for solving comfort issues in your house. These systems don’t have to have ductwork to give energy-efficient heating and cooling. Much like any other home comfort system, they can have troubles from time to time. Here are seven of the most typical mini-split problems 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 an issue with the condensate drain or drain line. It’s expected for a drain line to become clogged with mold, force water to back up and spill. Reach Paso Robles Heating and Air at 805-203-8667 for support 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 running. But there are a couple of instances where they could make sounds.

  • Popping or clicking: This can be due to the plastic housing expanding or contracting while the system is running.
  • Swooshing, crackling or gurgling: This can take place if your mini-split switches into defrost mode to stop 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 sign that something is off, such as not enough refrigerant, a bad circuit board or malfunctioning sensors. Your Paso Robles Heating and Air HVAC pro will be able to pinpoint and correct the situation fast.

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 could be the problem. Like we talked about before, icy coils could be the result of insufficient refrigerant, a bad circuit board or broken sensors. Contact us at 805-203-8667 for help.

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 transfer heat and keep your home comfortable. These leaks must be repaired by a licensed HVAC tech, so contact us at 805-203-8667 for assistance.

5. Mini-Split is Not Dehumidifying

Much like an air conditioner, a mini-split does a great job at dehumidifying during the summer. However, this may be stopped by mold in the condensate drain line. Another reason your mini-split air conditioner may not be dehumidifying very effectivelyis if it’s too big. A system that’s too large will cool down a space too rapidly without having time to dehumidify it. Mini-split size is calculated 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 usual smells and what they mean.

Musty, Sour or Mildew

If your mini-split smells musty, sour or like mildew, you likely have a mold issue. Have a pro like Paso Robles Heating and Air inspect and clean the condensate drain and drain line, if necessary.

Vinegar

If your mini-split smells like vinegar or has a sweet odor, you’re likely experiencing a refrigerant leak. Another surefire clue that you don’t have sufficient refrigerant is a lack of chilled air. Reach us at 805-203-8667 for help.

Fish

If your mini-split smells like fish, a couple of things could be wrong. Sometimes this smell means there is an electrical problem or that there’s a leak. Regardless, reach us at 805-203-8667 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 dead, your mini-split won’t turn on. In the majority of instances, putting in fresh batteries will resolve the trouble. If you’re still having trouble, reach us at 805-203-8667.
