In AC terms there is what is called TD (temperature differential). It is usually accepted that target TD is 20 deg F or if the air going into the unit is 75 deg f then it should exit at 55 deg f. therefore the temperature discharging from the unit should be about 20 degrees cooler than the air entering the unit. Depending on the temperature, humidity etc. this may be an inaccurate expectation. If you are not getting 20 deg TD, then it is time to evaluate your system and conditions. First, the conditions. Is there high humidity? the amount of energy used by the unit to cool the air is also used to remove humidity. With a finite amount of energy available, it is split between removing water vapor and cooling the air. The higher the humidity the less energy that can be used for cooling. Next the equipment. if the equipment is dirty, including the coils and the filters. the amount of air that can pass over the coils is reduced, as well as the efficiency. Look at TD on the line-set as well. there are two lines on your unit one large one small. the temperature should be obviously different. if not then you need a qualified service tech to help determine why. There are two parts to your cooling unit, one inside above the fan on your furnace and one outside. Check both. This is just a start, hope it helps Terry

How cold should the air be at the opening of an ac vent in your home?
15-20 degrees cooler than the air returning from the home to the air handler.
Why does your home ac run but not blow cold?
You need to have your refridgerant recharged
If its cold outside should you leave the AC off?
It would be advised if you do not want to get cold.
Why does the AC only blows cold while driving?
Well it should blow cold while driving and stopped. You probably need to get your AC recharged. Hope I helped!!
How cold should the ac blow out of the vent in a car?
40f - 45f is great
Is there hand warmers on Guam?
No On a cold day there its warmer than my mom sets the AC at home.
How would you know if you need a freon charge for your AC?
Pressure gauges. In a home or car AC there is small pipe and a large pipe going to the compressor unit outside or in the engine compartment. The large pipe should be cold and "sweating" ( dripping water).
Where should vents be placed-celiling or floor for AC?
Ceiling. Cold air fails
Should your cars AC work on a really cold day?
Yes, in fact in most modern cars the AC automatically comes on with the Defroster.
How cold should the air be blowing out of vents when the AC is running?
55 degrees to 60 degrees
If its cold outside should I turn the AC up?
You can turn the temperature of the AC up but if you turn the fan part of the AC up "high" or "low" it will only make it colder.
What should you wear if you are cold at home?
A jumper.
