Why You Should Deep Clean Your Wall-Mounted Air Conditioner Every 2 to 3 Years

Maintaining your wall-mounted air conditioner isn’t just about comfort—it’s key to keeping your system efficient, extending its lifespan, and ensuring healthy indoor air. While regular filter cleaning is essential, a professional deep cleaning should be done every 2 to 3 years. If you have pets, every 2 years is even more important—pet hair and airborne particles tend to build up faster.
What can you do yourself?
Every 3 months, rinse the filters with water to remove dust, allergens, and debris. This simple task can improve your air quality and keep your unit running smoothly.
What does professional cleaning include?
A certified technician will perform a deep cleaning that typically involves:
- Cleaning behind the indoor unit—an area that’s hard to reach
- Servicing the outdoor compressor, which is exposed to the elements
- Flushing the drain line to prevent clogs and leaks
Why does it matter?
Neglecting maintenance can lead to reduced performance, higher energy bills, or even breakdowns. Worse, a dirty system can harbor dust, bacteria, mucus, and mold—impacting air quality, especially for people with allergies or asthma.
Regular maintenance helps you:
- Extend the life of your system
- Breathe cleaner, healthier air
- Maximize efficiency and lower energy consumption
