Ductless mini-split air conditioning systems allow you to enjoy multi-room cooling, even if your home is not equipped with the ductwork required for a central forced air system. Mini-split systems have been popular in Europe for decades, and have just recently gained ground in the United States as an efficient and versatile cooling option. Like all air conditioning systems, your mini-split ductless air conditioner will need regular care and cleaning. If you experience problems, your air conditioning repair service in Baltimore can help you get your ductless system back online quickly to maintain your indoor comfort.

Power Supply Trouble

Ductless mini-split air conditioners typically use a wall-based power supply. If your system won’t turn on, this is the first thing you should check. Make sure the power cord is plugged in and that the circuit is not tripped. You should also check the cord and plug for wear and tear, which could interfere with the transfer of power and pose a safety hazard in your home. If the power supply seems functional, also check the batteries in your remote, as they may have been exhausted. A mini-split system that needs a power supply replacement or fails to operate even when it should be receiving signals from the remote should be evaluated by an air conditioning repair service to find the problem.

Dirty Filter or Vents

Dirt and dust are pulled into your air conditioner each time it draws air in for cooling. Over time, this dirt and dust can build up inside the filer and vents, causing a drop in cooling efficiency. You should check and change your air filter regularly—your air conditioning repair service can provide instructions and a timetable on which to perform this task. Additionally, you can check the air conditioner’s vents for dirt by shining a flashlight into the appliance and looking for buildup. If you observe significant clogs, it’s best to call in your air conditioning repair service for cleaning. A professional cleaning will remove dirt and dust from the entire unit, not just the areas you can reach without opening the appliance.

Refrigerant Leaks

Ductless mini-split systems use a refrigerant solution to cool the air inside your home. The refrigerant is circulated between the indoor and outdoor units via cables that run through the small opening in your home necessary to accommodate the system. Refrigerant leaks can occur when these cables become worn by weathering or affected by pests. If your ductless mini-split system turns on and off as it should but doesn’t blow cool air as you expect, this poor performance could be due to a refrigerant leak. Your professional air conditioning repair service can check for leaks and replace or repair any leaky lines in your system, as well as recharge the refrigerant safely so your system can efficiently cool the air in your home once more.
