Ultimately, it should be whatever temperature makes you comfortable, but I'd say a normal temperature would be around 65 degrees or so.
Whatever it is set to on your heater's control keypad.
55 degrees above zero Fahrenheit
Depending on the year, make, model along with if it has single or dual a/c systems and what the outside temperature is, it can be between 36 to 48 degrees...... Simply, the A/C vents temperature should be whatever you set the thermostat as.
One way to tell if you're low on coolant on a central AC unit is to feel the air coming out of the vents. If the air is warm or room temperature, it is a sign that you are low on coolant.
replace? why not fix it?
no
On the vents closest to the main unit it should read around the same temperature that the thermostat is set to after its been running and then as the venting increases the temperature should be less, between 2 to 10 degrees different depending on how well the ducting is in the attic........
Coming out of the vents around 43 degrees
There should be at least a 12 degree split between the incomming air and the air comming out of the vents.
no. if the unit is running the same temp of air comes out just for a longer time
yes it would save money :)
Smoke could be coming from the vents of your car for a number of reasons. You may have an internal car fire.
