Automobiles:

COLD TO HOT or if you want to be technical between 62+- to 92 +- Fahrenheit on average. if its too cold the heater obviously isn't working, but may I suggest first looking at your heater controls to ensure the temperature dial is set to warm (THE RED PART OF THE CONTROL)

Homes:

When trying to cool a typical house, the average central AC will only decrease the temperature by about 20 degrees. For example, when it is 100 degrees outside, the inside will typically cool to about 80 at best. However, in order to achieve the 80 degrees inside, the air coming out of the vent should be 45-55 degrees.

The temperature coming directly out of the vent is different than the ambient temperature of the house. The air coming directly from the vent should be 45-55, however this will not be the temperature in your home.

If using a thermometer stuck in the vent, and the blower fan on a medium speed, in the full cold position with AC on vent, temperatures should be between 40-50 degrees F. In the full heat position vent temps should be at least 140 degrees F.

What should the temperature of air from the heat vents be in house?

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........


What temperature should air be coming out of vents for heating?

Whatever it is set to on your heater's control keypad.


Do air vents bring heat?

Yes


What should the temperature of air from the AC vents be?

normally 15to 20 degree split between return air and discharge..


In order to heat a room should heating vents be placed near the floor or near the ceiling of the room?

Heating vents should be located near the floor since hot air rises. If the heating vents are located near the ceiling the heat would stay there and not warm the room.


How cold should air be that comes out of car vents with air conditioner on?

Depends on the ambient air temperature, humidity level, and type of refrigerant used.


With the air conditioner on what should the temperature be coming through the vents?

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.


How do the vents work on a hot air balloon?

the vents work because of the heat which can make the hot air balloon go up


Air conditioning coming out of vents in your car should be what temperature on average?

55 degrees above zero Fahrenheit


What should the air temperature be from the vents with the heat setting at seventy two degrees?

It depends on what your heat source is. An electric or petroleum fired forced air furnace will blow high volumes of air that is much hotter than 72 degrees Fahrenheit (perhaps as high as 90-100 degrees) for short periods of time. A heat pump, however, will generally blow air that is nearer the set temperature at lower volumes and for longer periods of time.


What can you do if you can't get heat from the rear upper vents in your 2001 Sienna?

I believe the upper vents are for A/C only. The floor vents are for the Hot air. Test your ceiling controls by moving the knob from cold to hot, you should hear the air pass from upper vents to lower vents. Providing of course you have selected REAR from the front control panel.


What would cause air to blow through the vents when nothing is on on a Mazda 626?

It is temperature control. Your car is wanting to breath or create a constant flow of air and will adjust itself with heat/cool or outside air. You should have an option to go manual and override its desire.


Taking heat out of the air will do what to the temperature?

Removing heat from the air will lower its temperature.


What does the icons mean on the dash?

Fuel level, heat or air conditioning up, both high and low, high only, floor only. Center vents are for air conditioning output only, no heat. Heat is designed to blow out side and floor vents only. NOT center. Center is only for air conditioning or summer vents.


Why should heating vents be placed on the floor?

Heating vents should be placed on or near the floor because heat rises. In rising, it will warm the air of the room. If the heating vent were near the ceiling, the room would stay chilly, even though heat was being poured into it.


Where in a room should vents be placed for central air conditioning?

In my opinion where the supply vents are located is not as important as where the return air vents are located. the supply vents should be located towards the outer walls if possible. the return air vents should be located towards the center of the dwelling if possible. every effort should be made to get the return air vents as high as possible on the wall , if not in the ceiling.Remember you are trying to get the warm air back to the a-coil so it can be pumped outside through the refrigeration lines to the condensing unit. if the ductwork is used for heating also you should put some return air vents down low to get the cool air to the furnace. This is my personal opinion and may not be everyones.


Can you cover the vents to the crawlspace under the house?

Vents to the crawlspace under a house can, indeed, be covered. But that creates a "dead air" space. Vents provide, well, ventilation. Consider why covering them is necessary. Some vents have screens over them to keep critters out but let air in and through. NEW ANSWER All vents that lead to the outside should be completely covered. An unconditioned crawlspaces has very poor air quality. Opening the vents just adds to the problem. When the outside temperature hits the crawlspace temperature, condensation occurs which results in excessive humidity. The correct fix depends on where you live geographically but is basically the same. The crawlspace does need air. It needs air from your hvac system. That is how to avoid dead air.


How do you take off the heat vents in a home?

Forced air vents set flush in the floor? They generally just lift straight out.


What does air temperature measure?

Air temperature measures the amount of heat that is in the air. Thermometers are used to measure air temperature.


How cold should the air be blowing out of the vents when the central AC unit is running properly?

There should be at least a 12 degree split between the incomming air and the air comming out of the vents.


Why does a 2003 Crown Vic with auto temp control blow heat and ac from the defrost and floor vents but no air through the dash vents?

Because the air selector died.

some thing is probley cloging the vents take it appart and ckeck.


Should cold air vents be closed when using central air conditioning?

no


How does water moderate temperature?

Water moderate air temperature by absorbing heat from air that is warmer, and releasing the stored heat to air that is cooler.


Why no heat is coming out of your vents on your E-320?

you should probably run a duster thorgh it and/or check the pipes to it with it running =there might be an air leak
