7 Common Mini-Split Problems and How to Fix Them

July 12, 2021

Having mini-split installation done is an excellent solution for solving comfort difficulties in your residence. These systems don’t need 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 solve 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 problem with the condensate drain or drain line. It’s typical for a drain line to be clogged with mold, force water to back up and drip. Call Giordanos Heating and Air Conditioning at 203-772-8319 for help and we’ll get your drain unblocked quickly.

2. Mini-Split is Making Noise

Mini-splits normally don’t generate much noise when they’re running. But there are a few situations where they could create 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 switches into defrost mode to prevent itself from freezing up.

You shouldn’t be troubled if you hear these noises because they’re typical. However, if your mini-split keeps going into defrost mode, it’s a sign that something is wrong, like insufficient refrigerant, a flawed circuit board or broken sensors. Your Giordanos Heating and Air Conditioning HVAC pro will be able to find and solve the situation quickly.

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

If your mini-split is not heating or blowing hot air, frozen coils may be the issue. Like we discussed before, frozen coils might be the consequence of low refrigerant, a bad circuit board or malfunctioning sensors. Reach us at 203-772-8319 for help.

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 home cool. These leaks must be resolved by a licensed HVAC pro, so call us at 203-772-8319 for help.

5. Mini-Split is Not Dehumidifying

Like an air conditioner, a mini-split does a great job at dehumidifying during the summer. However, this can be stopped by mold in the condensate drain line. Another reason your mini-split air conditioner may not be dehumidifying very efficientlyis if it’s too big. A system that’s too large will cool down an area too rapidly without having time 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 get 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 may have a mold issue. Have a pro like Giordanos Heating and Air Conditioning check 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 possibly dealing with a refrigerant leak. Another certain hint that you don’t have sufficient refrigerant is a weak flow of cool air. Call us at 203-772-8319 for help.

Fish

If your mini-split smells like fish, a couple of things could be wrong. Sometimes this smell means there are electrical issues or that there’s a leak. Regardless, call us at 203-772-8319 for support.

7. Mini-Split Will Not Power On

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 most experiences, putting in new batteries will fix the situation. If you’re still having trouble, reach us at 203-772-8319.
