Cassette AC Gas Refill in Chennai
When your Cassette AC runs but won’t cool, it’s usually low refrigerant. We locate the leak, repair it, evacuate the system and recharge it to the manufacturer’s exact spec. A cassette AC is recessed into a false ceiling with four-way airflow, so ceiling access, drain-pump operation and blower balance need particular attention.
Why Cassette AC Gas Refill is different
- A cassette AC is recessed into a false ceiling with four-way airflow, so ceiling access, drain-pump operation and blower balance need particular attention.
- For gas refilling, that means the job is matched to your Cassette AC rather than done to a generic checklist.
- Every job is doorstep, uses genuine parts, and carries a 30-day service warranty across Chennai.
We first find and fix the leak (rather than just topping up), pull a vacuum to remove moisture and air, then charge the correct refrigerant type and quantity by gauge for your Cassette AC — so cooling is restored and the fix lasts.
Cassette ACs sit flush in a false ceiling and blow air in four directions, so the usual call-outs are a failed drain pump dripping onto the ceiling, uneven cooling from clogged filters, or a blower running loud. Servicing needs ceiling access and care around the false-ceiling grid — our team is set up for it.
We handle scheduled maintenance, drain-pump and blower repair, gas charging and filter service, and can put commercial units on an AMC so they never fail during business hours.

Frequently asked questions
Why does my Cassette AC need gas so often?
Refrigerant is not consumed — if a Cassette AC needs frequent top-ups there is a leak. We detect and repair the leak first, so you are not paying to refill a system that keeps losing gas.
Which refrigerant does a Cassette AC use?
It depends on the unit — commonly R32 or R410A on newer models, R22 on older ones. Our technician checks the nameplate and charges the exact type and quantity your Cassette AC is rated for.
