Cassette AC Foam Jet Deep Cleaning

About the service

Our Cassette AC Foam Jet Deep Cleaning service is for ceiling cassette ACs that are running but not cooling like before, smelling bad or blowing weak airflow.

This service covers 0.75 . 1 ton cassette ACs in small cabins and rooms, and 1.5 . 2 ton cassette ACs in larger offices, shops, showrooms, clinics, gyms and restaurants. We use AC safe foam chemicals and controlled water cleaning to clean the indoor coil, blower path, drain tray and filters so your cassette AC gives better cooling, fresher air and smoother airflow.

Ideal when you notice.

• Cassette AC cooling has dropped compared to earlier

• Bad or damp smell when you turn on the AC

• Low airflow even on higher fan speed

• Water droplets or light sweating near the grill

• Dust visible on the cassette panel and vents

Our process

1. Pre cleaning inspection
The technician checks for each cassette AC.

• Present cooling and airflow

• Visible dust on panel and filters

• Drain tray and water outlet condition

• Any existing water leakage or damp marks around the ceiling

This confirms that the unit is fit for wet cleaning and helps decide the cleaning depth.

2. Power off and area protection
The Cassette AC is switched off from the remote and power is isolated from the MCB if needed.
The technician covers the area below the cassette with sheet or protective cover to prevent dirty water and dust from falling on furniture or flooring.

3. Panel, filter and basic dust removal

• Front panel is opened

• Filters are removed and washed thoroughly

• Loose dust and debris around the intake and outlet sections are cleaned

This step alone helps 0.75 . 1 ton units in small rooms breathe better and improves airflow.

4. Foam jet coil and blower cleaning
Using AC grade, non corrosive foam cleaner.

• Foam is applied on the evaporator coil and air path where accessible

• The foam breaks sticky dust, fungus and oily deposits

• After correct dwell time, the coil is rinsed with controlled water so dissolved dirt flows into the drain tray

This is critical for 1.5 . 2 ton cassette ACs that handle large areas and run for long hours.

5. Drain tray and drain line cleaning

• The drain tray is cleaned to remove sludge, algae and dirt

• Basic drain outlet cleaning is done to support proper water flow

This helps reduce water leakage, smell and drain blockage, especially in humid environments.

6. Panel, louver and visible surface cleaning
The technician wipes and cleans.

• Cassette outer panel and frame

• Air outlets and swing louvers

• Any visible marks from previous leaks

This improves hygiene and makes the cassette look cleaner in your ceiling.

7. Test run and performance check
After reassembly and power on.

• AC is run in cooling mode

• Airflow and temperature drop are checked

• Smell from the outlet is checked

• Drainage is observed to confirm no internal choking

A quick summary is shared of the changes after deep cleaning.

What we need from you

• Stable ladder or platform access to the cassette unit

• MCB or power switch access for safe isolation

• Clear space below the cassette for covering and work

• Access to water and a drain or bucket nearby

• Basic idea of how many hours per day the AC runs and in what type of area

Why choose foam jet deep cleaning for cassette AC

• Cleans more than just filters. focuses on coil, air path and drain tray

• Helps 0.75 . 1 ton cassette ACs cool cabins and small rooms faster

• Keeps 1.5 . 2 ton cassette ACs efficient in halls, showrooms and open areas

• Reduces bad odour, fungus, hidden dust and bacterial growth

• Can improve cooling and power efficiency when the coil and blower were heavily choked

• Uses AC safe chemicals suitable for aluminium coils and plastic parts

Frequently asked questions

Q1. How often should I do Cassette AC foam jet deep cleaning

• Home or low dust office use. about once a year before heavy summer

• High dust, high traffic or long hour use. every 6 months is better for cassette ACs

Q2. Will deep cleaning fix cooling problems completely
If low cooling is mainly due to dust, fungus and restricted airflow, foam jet deep cleaning can make a major difference.
If the problem is low gas, weak compressor, PCB fault or fan issue, cleaning will help airflow but you will still need repair work.

Q3. Is the foam chemical safe for cassette AC
Yes. We use non corrosive AC coil cleaner designed for HVAC equipment and ensure proper rinsing so no harmful residue remains.

Q4. Is gas filling included in this service
No. This is a cleaning and maintenance service. Any gas issue, compressor fault or PCB repair is treated as a separate job.

Q5. Does tonnage change the cleaning method
The method is similar. but 1.5 . 2 ton cassette ACs usually have larger coils and more running hours, so deep cleaning has an even bigger impact on their cooling performance and energy use.
