I don't know anything about using an AC

[ghoshop]

I have a 2nd hand split AC 2 ton which is old. I don't know how to maintain my AC. I might be doing things dangerous for my AC.

I use AC from 1pm and put it off at 4am at night. I switch off my AC at 4pm for 30-40 minutes because I think AC needs rest. I keep temperature set at 18°C or 21-22 because compressor starts quickly.

I read on internet that frequently switching AC off is bad and others recommend to switch off after 8-10 hours. I don't know what to do? I cannot use so long and cannot switch it off. I switch it off when I wake up from sleep. I sleep at 8.30pm.

I might be damaging my ac by putting it off for 40 minutes at 4pm (start from 1pm). I don't know. When should I switch it off? How long at a stretch should I keep it on?

All good, I am not seeing any wrong ways here. Just connect a voltage stabilizer for better life of PCB

You are damaging your health by not getting enough sleep rather think about damaging AC and bec of 2nd hand AC you are worried and you shld be as you don't know what was it's actual working condition before.

If the AC is not too old say 2-3 years then you need not to worry..
