7 Common Mini-Split Issues and How to Resolve Them

July 12, 2021

Having mini-split installation done is a fantastic approach to solve comfort problems in your house. These systems don’t need ductwork to provide energy-efficient heating and cooling. Like any other home comfort system, they can run into issues sometimes. Here are seven of the most frequent mini-split problems 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 could be a problem with the condensate drain or drain line. It’s common for a drain line to become clogged with mold, force water to back up and leak. Call Titan Heating & Air Conditioning at 514-600-5499 for assistance and we’ll get your drain unblocked promptly.

2. Mini-Split is Making Noise

Mini-splits normally don’t generate much noise when they’re on. But there are two instances where they may create sounds.

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

You shouldn’t be troubled if you hear these noises since they’re expected. However, if your mini-split keeps switching into defrost mode, it’s a clue that something is up, like low refrigerant, a bad circuit board or defective sensors. Your Titan Heating & Air Conditioning HVAC professional will be able to pinpoint and resolve the situation rapidly.

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, iced-over coils can be the effect of insufficient refrigerant, a faulty circuit board or broken sensors. Reach us at 514-600-5499 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 needs refrigerant to transfer heat and keep your residence comfortable. These leaks must be fixed by a licensed HVAC pro, so reach us at 514-600-5499 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 interrupted 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 an area too rapidly without having time 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 tell you that something is wrong. Here are five of the most typical 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 specialist like Titan Heating & Air Conditioning check and flush 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 sign that you don’t have enough refrigerant is a lack of cold air. Contact us at 514-600-5499 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 that there’s a leak. Regardless, call us at 514-600-5499 for help.

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 switch on. In the majority of experiences, putting in new batteries will resolve the situation. If you’re still having trouble, reach us at 514-600-5499.
