Having mini-split installation done is an excellent approach to solve comfort difficulties in your home. These systems don’t need ductwork to provide energy-efficient heating and cooling. Like any other home comfort system, they can experience problems from time to time. Here are seven of the most typical mini-split problems and how you can resolve them.

1. Mini-Split Leaks or Can’t Drain 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 typical for a drain line to be clogged with mold, forcing water to back up and drip. Call Contra Costa Heating & AC at 510-343-9841 for assistance and we’ll get your drain unclogged quickly.

2. Mini-Split Is Much Noisier

Mini-splits usually don’t make much noise when they’re operating. But there are a few instances where they might create sounds.

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

You shouldn’t be worried if you hear these noises as they’re expected. However, if your mini-split keeps going into defrost mode, it’s a symptom that something is up, like not enough refrigerant, a faulty circuit board or broken sensors. Your Contra Costa Heating & AC HVAC technician will be able to locate and resolve the situation fast.

3. Mini-Split Blows Cold Air in Heating Mode

If your mini-split is not heating or blowing hot air, frozen coils could be the issue. Like we discussed previously, frozen coils may be the consequence of not enough refrigerant, a failing circuit board or broken sensors. Call us at 510-343-9841 for support.

4. Mini-Split Cooling Mode Won’t Work Properly

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 cool. These leaks must be resolved by a licensed HVAC professional, so reach us at 510-343-9841 for help.

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 halted by blockages in the condensate drain line. Another reason your mini-split air conditioner may not be dehumidifying very effectively is if it’s too big. A system that’s oversized will cool down a space too fast without having time to dehumidify it. Mini-split size is planned on square footage and BTUs.

6. Mini-Split Produces Strange Odors

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 could have a mold issue. Have a professional like Contra Costa Heating & AC check and rinse 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 probably experiencing a refrigerant leak. Another certain clue that you don’t have sufficient refrigerant is a low concentration of cool air. Call us at 510-343-9841 for support

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 there’s a leak. Nevertheless, call us at 510-343-9841 for support.

7. Mini-Split Won’t Turn On

If your mini-split will not power on, look at the remote first. If the batteries are dead, your mini-split won’t run. In the majority of situations, replacing the batteries will solve the issue. If you’re still having trouble, call us at 510-343-9841.
