The truth is that how you maintain your system throughout the year greatly affects how the air in your home feels and how hard the system has to work. Instead of doing a deep clean only when the situation has already become unpleasant, you can establish a simple and clear routine—and understand how to clean your air conditioner at the beginning of the season, in the middle, and after periods of heavy dust.

How to clean your air conditioner at the start of the season – getting ready for summer

The first step in figuring out how to clean an air conditioner is determining when to do it. The start of the season is an excellent opportunity to do a little “reset”:

  • External cleaning of the indoor unit
    Wipe the exterior plastic with a very damp (not wet) cloth. Do not pour water or harsh cleaning agents into the openings.
  • Visual inspection of air conditioning vents
    Look at the grilles – is there dust accumulation around them? Are there signs of dirt on the wall or ceiling? At this stage, we are not cleaning the ducts, just getting an initial picture.
  • Short trial run

  • Renovation with plasterboard, polishing, gluing,
  • Massive coloring,
  • A period when the house was full of boxes, packaging, and dust,

  • Dust quickly accumulates around the air conditioning vents, despite regular cleaning.
