If you are planning to install a ductless mini split air conditioner in your home or office, it would be a good idea to learn some maintenance tips. Mini split systems are efficient and effective in cooling rooms of almost every size. Let’s take a look at some common problems with ductless mini split air conditioners and how to prevent these problems.

Ductless Mini Split Air Conditioner

There are three components in a ductless mini split air conditioner – the compressor, the air handler, and a remote. The compressor unit is located outdoors, while the air handler is located inside a room. It is easy to install this type of air conditioner, as in most cases installation can be done without rebuilding or remodeling your existing building. The indoor unit is connected to the outdoor unit through pipes and wires passing through a hole in the wall or ceiling. Another benefit of using ductless mini split air conditioner is that you can install them almost anywhere in your home.

Common Installation Problems

Many ductless mini split air conditioners come with an installation kit. Before you decide to self-install, check whether there is any restriction on self-installation. Some manufacturers will cancel your warranty if you install on your own. It is advisable to hire a St. Louis HVAC company for installing your unit.

Regular Cleaning and Maintenance

Regular cleaning and maintenance will help extend the life span of a ductless mini split air conditioner. In general, this type of air conditioner will last for 12 to 15 years. However, depending on weather conditions and humidity levels in your locality, the system may last even longer. If you want your air conditioner to run at its best for years, clean the filters and coils regularly. Regular cleaning will help prevent clogging and ensure unobstructed airflow. In most of today’s air conditioners, you will find a tab on the air handler to remove the filters, so that you can clean and replace them easily. You can use a garden hose to wash away debris, dirt, and grime in the compressor unit located outside of your house. Remember to unplug the system before cleaning it.

Useful Maintenance Tips

  • Keep the area around the compressor unobstructed for optimal airflow.
  • Keep the compressor unit clean to prevent overheating.
  • A ductless mini split air conditioner system works at its best when the temperature is between 14°Fahrenheit and 109°degree Fahrenheit.
  • If the remote stops working, push the reset button.
