How to Operate and Maintain a Ductless System

June 15, 2015

Ocala’s hot summer weather is just around the corner, which means the need for effective indoor cooling is on the horizon. Ductless systems provide a way to cool your home for optimal comfort while maintaining energy efficiency. Correctly operating and maintaining your ductless system can extend the system’s useful life and maximize efficient cooling.

Ductless Air Conditioners Explained

Often referred to as mini splits, ductless systems may be used to cool an entire home or just one room. As opposed to traditional air conditioners where air is delivered via ductwork, ductless systems deliver air directly into the space. Mini splits have three main parts: an indoor compressor, an outdoor air handler and a remote control for easy, convenient operation. Installation can be done without extensive work beyond a three-inch hole in the wall used to connect the indoor and outdoor components.

Operating Ductless Systems

Because ductless systems work differently than whole-house units, there are some points homeowners should be aware of:

  • Temperature setting – The temperature settings of a mini split are more accurate than the whole house temperature. When the home is being cooled, you’ll often find warm and cold spots. Mini splits address this by providing the exact temperature to a specific location.
  • Energy efficiency – In order to preserve the energy efficiency of your home, raise the temperature in the room by a few degrees when you’re away. This will help preserve your comfort while using less energy when no one’s home to enjoy it.

Maintaining a Ductless Air Conditioner

If your mini split is properly maintained, it can achieve a useful life of about 12 to 15 years. In order to maximize the life of your system and to keep it running efficiently, proper care and maintenance must be done on a continual basis.

The easiest and most important way to maintain your system is through cleaning. First, filters should be checked monthly and cleaned when warranted. In the air handler, there will be filters that need to be removed and cleaned. Additionally, care should be taken to ensure the outdoor compressor is maintained. It’s common for dust and debris to accumulate around the outdoor unit. To address this, use a garden hose to gently wash off the outdoor component. This should be done on a regular basis throughout the cooling season. As with all appliance maintenance, be sure to turn off the power before cleaning any part of the system, whether indoor or outdoor.

Ductless System Tips

When using a ductless system to cool your home, there are several things to keep in mind.

  • Mini split air conditioners work best in temperatures between 14 and 109 degrees. If the weather in your area is regularly outside this range, mini splits may not be the best solution for your heating and cooling needs.
  • As with all air conditioners, removing water from the air is an important part of the cooling process. It’s important that the water leaving the mini split has a place to go and can be easily directed to a drain or outside a home. If your chosen installation location prevents this, consider other options.
  • Airflow is critical to the operation of your system. Be sure that the outdoor component is placed in an area where airflow isn’t restricted by vegetation or other outdoor structures. Decreased airflow will substantially impact the ability of the system to cool the home.
  • A dirty outdoor unit can result in overheating, which can result in costly repairs and an uncomfortable indoor air environment. Keeping the outdoor unit clean is a vital part of the overall operation of a ductless system.
  • In the event that the remote stops working, try resetting it. If this doesn’t work, replace existing batteries with fresh one. If neither troubleshooting method resolves the issue, contact the manufacturer.
