You should leave your air conditioner set on 80 degrees when you go away on vacations. I you have a programmable thermostat for your air conditioner set it to lower the temperature to 70 right before you get home.
Whatever temperature is comfortable for you. HVAC systems are designed to maintain 75 degrees for A/C and 70 degrees for heating.
In heating, the air coming out of the registers is in the range of 110-150 degrees F, so it feels warm as it approaches us. In cooling, the air out of the registers is 45-65 degrees F.The HVAC Veteran

Yes, it does not change any function of the the air conditioning or the temperature at which it disperses air, it just runs longer to get to the temperature you set it at. If it runs longer though it will cost you more.
A pressure for air-condition is between 60 ~ 70 psi charging of split type air conditioner is required.
When you are running your air conditioner and it stops then the air conditioner is froze up. You have to cut it off for a while, and let it warm up. You have to turn the thermometer between 70-75 to keep it from freezing up.
I see this happen a lot. The thermostat is turned down way to low (60 degrees or lower) causing ice to build up on the air conditioners condenser coils. Which causes the air not to get through the coils. The icing of the condenser creates a blockage and the air conditioner doesn't cool the house or room. Making you think it is not working. If not corrected the compressor will overheat. (Not Good). Turn the air conditioner off until the ice has melted (probably 24 hours). Then turn the air conditioner back on with the thermostat set to 68 to 70 degrees and it should go away. If not call a technician.
Hermit Crabs like Humidity. They need 70-80% humidity to survive. But, if it like 100 degrees and no humidity i recommend to put a fan or air conditioner on then, or in their cage.
60 to 70 psi depends up on copper pipe length
