Have a new ac system installed thermostat is set at 76 shows room and setting the same all the time shouldn't the room temp rise before unit comes on.

Normal ACs (non inverter) work in the following way

• The AC compressor runs continuously till set temperature is reached in the room
• The compressor then switches off, but the blower fan in the wall mounter unit keeps running. Durint this time the AC fan blows air out at Room temperature (which feels warmer)
• When temperature of room rises then compressor starts running again. During theis period the air coming out from the inner uny is cooled by the condenser coils
• And the process is repeated.... as long as you keep AC running

Ac works this way throught the operation period.
Now if you feel that your AC keeps switching off and on very frequently check the following

• Your AC may be over powered for room *for example a 1.5 ton AC installed in a scenario where 1 ton is enough)
• If there is voltage fluctuation in your area then the compressor may keep shutting don on large voltage swings
  • Solution: Get a Stabilizer
• You have set the temperature setting too high. Max temp suggested for ACs is 25 degree Celsius, any higher will mean the compressor shuts down often. Remember every compressor shutdown and startup draws a high starting current
  • Set AC temperatures between 22 and 24 degrees Celsius
• The thermostat/ Temperature sensor is faulty
  • Get unit inspected by Authorized technician
• There is dust buildup on the outer unit / compressor unit. The dust buildup may cause overheating by preventing efficient heat exchange, This may lead to overheating of compressor and it shuts down to, prevent damage to itself
  • Get unit serviced by Authorized technician
• The fan motor of the outer unit is not working properly
  • Get unit inspected by Authorized technician

Remember to get the AC serviced at least thrice a year to ensure smooth operation

if the ac unit is over 7ft from the floor, that would explain what is happening
the thermostat only reads incoming air from the room and if that thermostat is higher than the people in the room , what your are feeling is the cold air but the unit is reading the hot air above you and will continue to run until the whole lot air up to the thermostat is cooled down
but setting the thermostat to a higher setting your are setting the thermostat to that uncooled air temp and so it will switch off

if you have it set at 60 F and it is working at 65 to 68 F then that would be about right
as the air is cooled the cold air falls to the floor and out under the door, open window or anywhere else it can escape
the unit has to be at 80% room height so if it is set in a window then when the cold air gets up to the thermostat or ac level in the window then it will stop cooling
So if the ac unit is say 4ft from the floor and the ceiling height is 8 ft then the ac will only cool the bottom 4 ft
cold air does not rise but falls down
if you are using a ceiling fan then the cold air is stirred up and the 65F sounds about right
remember that the setting temp ( what you set it at) is the lowest temp that it will go down to before it stops cooling and if that is not reached it will keep working to attain that temp and if the room is too big, air leaks under door . around the fit in the window , no insulated walls , hot exterior wall,etc then maybe 65 F is the best you will get

Hello.I think they are on to something with shortcycling on temp sensor.I think it should be sampling the return air instead of (inside coils ?).A 2*f dead band use to be built in (factory installed) to thermostats to prevent on/off, but not sure in this case.Try a new sensor location(return air) and see if anything changes.

the thermostat controlling your unit likely has a window type of programming for digital or mechanical adjustment for older style thermostat that sets a minimum off temp and a maximum on temp, there may be an adjustment to set the range it operates at, otherwise you may have a defective thermostat controller unit and it needs replacing also insure that the temperature sensing element is clean and free of dust build-up and your filter is clean

may need to check frean in unit it may be low if it runs to lone it will freez up

it could be the thermostat is loose on the subbase or if you went from OFF to COOL and the stat is a digital stat It will not come on for five min. This is a delay set by the manufacture to protect the compressor. during normal operation you will not notice because thier will be more than 5 min from the time it shuts of till it need to come back on but if the system switch is set to off and you switch to cool or unit just shut off it will always delay 5min. usualy there will be some insdiction on the screen that it is in delay like a flashing COOL or SNOW FLAKE or the word WAIT. the unit will not be running until the flashing words go solid

the "in recovery mode" is refering to a thing called energy recovery management its one of the features on your tstat what it does- when you are using the program on your tstat the "in recovery" starts your unit early so if the tstat is set to be 70 degrees at 8 in the morning when 8 o clock hits it will already be 70 degrees in your house you can turn this feature off if you want in the installation setup codes

DOES THE HOUSE FEEL DRIER IF IT IS 80 OUTSIDE WITH ALOT OF HUMIDITY THE UNIT WILL RUN FOR A LONG TIME TO REMOVE THE MOISTURE(HUMIDITY) OUT OF THE HOUSE BEFORE TEMP DROPS DRAMATICALLY IS THERE WATER COMING OUT OF THE DRAIN PIPE OUTSIDE

the unit runs all the time because of the fan (ventilation motor)-but it is not working on cooling or heating all the time - The ventilation motor pushes the air from the room through the machine and when the termostat is reading that you set it up for cooler air or warm air it will turn on the air conditioning part or the heating part of the machine-it is very good system actually
