Wall-Mounted Air Conditioner Cleaning
At Conduit Expert, we follow a meticulous process to keep your wall-mounted air conditioner efficient and free of dirt, mold, and bacteria.
When Should You Have Your Wall-Mounted Air Conditioner Cleaned?
Over time, dust, mold, and debris can accumulate inside the unit, affecting performance and indoor air quality. Signs that cleaning is needed include:
- Water dripping from the indoor unit
- Small black debris expelled when the unit starts
- Unpleasant odors while the system is running
- Black marks on the shutters
- More frequent allergy symptoms
We recommend professional cleaning every 2 to 3 years to maintain efficiency and air quality.
Our Cleaning Process
1. Inspection and Assessment
Before beginning, we thoroughly inspect your unit to ensure it functions properly and its filtration system is effective.
2. Disassembly and Access
We turn off the system and carefully remove the casing to access the evaporator coil, a critical component for cooling efficiency.
3. Deep Cleaning and Dirt Extraction
Using professional equipment, we extract dirt and debris and apply a biodegradable coil-cleaning solution to dissolve stubborn buildup.
4. Antibacterial Treatment
To prevent future mold and bacterial growth, we apply an antibacterial treatment that improves indoor air quality and extends the life of the unit.
5. Rinsing and Final Inspection
We rinse the unit thoroughly to remove residue and clean the outdoor condenser with soapy water and a pressure rinse for optimal performance.
