What should the air temp be coming?
The air coming out should be 14 to 20 degrees cooler than the air flowing in. Move the thermometer to a vent in each room or area of your home. If any of the vents are much colder or warmer than another, there may be a problem with the ductwork, or the distance may be too great from the blower.
Why is my Nest thermostat blowing cold air?
If your heating and cooling system is a heat pump and it blows cool air when your Google Nest thermostat is in heating mode (the background on the display is red), you may need to adjust your heat pump O/B wire orientation settings on your Nest Learning Thermostat.
How cold should the air coming from my air conditioner be?
Now, from the example above, with 75 degree air being pulled in at the air filter, what temperature should we expect to be blowing out? Well, the general consensus is somewhere between 14 to 20 degrees colder than the intake temperature. From my example, 55 to 61 degrees would be an acceptable range.
What should temperature be coming out of vent?
In a normally operating air conditioner, the temperature of air coming out of the supply vents should be about 20˚F lower than ambient temperature inside the room. This means that if your room is currently at 90˚F, then the cool air coming out of the supply ducts should be at around 70˚F.
What should the temperature of the a / C be outside?
On a central HVAC system, a 20–25 degree differential (between outside air and temp of air coming out of duct work) is about as good as you can expect. Recharged the freon. It’s 103 outside and now the a/c is blowing 66. to answer. This question is in the General Section. Responses must be helpful and on-topic. Oops.
Why does air come out of vents in the summer?
A common problem many people have both in the summer and in the winter is air coming out of the HVAC vents at seemingly inadequate temperatures. Whether you’re trying to cool your home in the summer or warm it up in the winter, it’s often hard to gauge if the air blowing out of your vents is the right temperature.
Now, from the example above, with 75 degree air being pulled in at the air filter, what temperature should we expect to be blowing out? Well, the general consensus is somewhere between 14 to 20 degrees colder than the intake temperature. From my example, 55 to 61 degrees would be an acceptable range.

What should the temperature be between supply and return air?
An ideal temperature differential between air coming into to be cooled, and the air being blown out is 14° to 20° F. The temperature difference between return and supply air is known as the evaporator Delta T. What Is Supply and Return Air?
Where does the cool air come from in an AC system?
Air enters your home through the supply vent, then goes back into the system through the return grill. The indoor AC part that actually cools your home’s warm air is called the evaporator coil(pictured as a snowflake in the image above). When we calculate evaporator Delta T, we’re trying to see how efficiently the coil is working.
