St. Louis HVAC – How to Maintain Ductless Mini-Split HVAC

February 4, 2016


Homeowners are using ductless mini-split air conditioners as a cost-effective alternative to central air conditioners.

If you are one of them, you may want to learn some tips on how to maintain or troubleshoot your mini split air conditioner on your own. Regular maintenance and timely repairs help extend the lifespan of air conditioners.

Installation of Mini-Split Air Conditioners

Ductless mini-split air conditioners come with three components – an outdoor unit, an indoor unit, and a remote. The outdoor unit contains a compressor, while the indoor unit consists of an air handler. Unlike a central air conditioning system, a mini-split air conditioning system does not require extensive reconstruction for installation. The indoor and outdoor units are installed and connected with pipes and wires. A small hole is drilled in the wall to pass the pipes and wires through.

Regular HVAC Cleaning and Maintenance

If properly cleaned and maintained, a mini-split air conditioner can last for 12 to 15 years. Regular cleaning is perhaps the most important maintenance task. Remove and clean the filters regularly with soap and water. If a filter is damaged, replace it as soon as possible. Use your garden hose for cleaning the compressor. Make sure that you unplug the system before cleaning it.

Some Additional HVAC Tips

  • Remove any obstructions in front of the compressor to ensure smooth air flow.
  • Clean the compressor regularly to avoid overheating.
  • If the remote stops working, check the reset button. If the problem persists, seek professional help.
