A FEW HELPFUL ANSWERS

Before
we drop by.

Not sure what your aircond needs?
Send us a photo and describe the issue.

Ask us on WhatsApp
When is a chemical wash suitable?

Heavy internal dirt, persistent smells or weak airflow may need a deeper clean. We check the condition of the unit before recommending the suitable scope.

How much does a chemical wash cost?

Prices start at RM150 for one 1HP wall-mounted unit. Other listed prices depend on unit type and HP. Select your unit details to see the price; additional work is quoted separately.

Does chemical washing include gas top-up or repairs?

No. Gas top-up and repairs are quoted separately after inspection. Cleaning alone will not fix every cooling problem.

Do you clean cassette units in offices and commercial premises?

Yes. Choose ceiling-mounted (cassette) and the HP to see the listed price per unit. For several units, special access or planned maintenance, send a unit list and location for a quotation.
