It should be at least 40 degrees air from the outlets. The house temp will be ten to fifteen degrees lower inside than the outside. The inside temp depends on all the insulation features of your home.
you would turn the temperature down for cooler air temperatures in a car, in a house the air temperature coming out the vents does not change based on the thermostats set point
Setting a lower AC temperature will not necessarily cool your house faster. The air conditioning system works at a constant rate, so the time it takes to cool your house will remain relatively the same regardless of the temperature setting. However, setting a lower temperature than necessary will result in the AC running longer without providing any additional cooling benefits, leading to wasted energy.
By having the air conditioning set at 75, that means the air conditioner will come on only if the temperature in the house rises above 75. It will maintain the interior temperature at a temperature of not more than 75. If the outside air temperature is lower than 75 and you want the interior temperature to stay at 75, you will need to turn on the furnace and set it at 75. Now the furance will come on if the temperature in the house drops below 75 but will not come on if the temperature in the house rises above 75.
The inside air space is warmer than the set temperature but air is flowing uniterupted, compressor is attempting to turn on but is hot, the temperature and the pressures may be the same.
The temperature inside a house without air conditioning can be around 10-20 degrees hotter than the temperature outside. So, if it's 90 degrees outside, it could be around 100-110 degrees inside the house without AC.
Anywhere from 15-20 degrees F below ambient (return) temperature. Take a temperature reading at a cold air register and at the air return. Registers farther away from the blower will be slightly warmer than those closer. So, if it's 85 degrees in your house when you get home, and you fire up the AC, don't expect air any colder than about 70 right away. As the AC pulls the air temp in the house down, the air from the registers should become cooler. Also, don't expect a central AC unit to cool a house much below 20 degrees cooler than the outside temperature. If it's 100 degrees outside, 80 degrees inside is about the best you can expect from a central AC.
as close to the air temperature outside. then no cooling or heating of air has to take place
Air temperature and humidity levels.
If the AC evaporator is in the basement or somehow lower than the rest of the house, the blower could be having trouble lifting the air. Recognize that cold air is quite a bit heavier than warm air. The warm air wants to go up, the cold air wants to go down and the blower motor can have quite a difficult time fighting that battle. If the AC repaiman suggests a booster fan, he's probably right.
The temperature difference between the air coming out and the air going back in.
That's the entire point of an AC unit. it's to keep your house at a steady temperature
The water from an air conditioner you are referring to is known as condensation. This occurs when there is a difference in temperature between an object and the temperature of the air.
