What should the temperature of the air blowing out of our vents be?
Question:We have constant problems with our A/C unit. It was freezing up all the time, and the maintenance guys at our apartment complex got an outside company to come look at it. They replaced our blower unit and rewired everything, and now we can't even get cold air out of the vents! The air coming out of the vents is anywhere from 65-68 degrees! This cannot be normal! Our A/C never cut off last night, and it took all afternoon and all night for it to cool our apartment by 5 degrees! I think we're going to have a really high power bill. Can someone let me know what the air temperature at the vents is supposes to be? Also, if it's 95 degrees outside, can I expect my unit to be able to cool my apartment to 70 degrees, or is 75 as good as it gets?
Answers:
65 to 68 degrees is pretty normal. A 22 degree difference between inside and out is excellent. The other air problem may be that when the new blower was installed it may not have been installed with the high speed fan option selected at the fan/ housing junction of fan. ( you may want to also make sure your filter is clean and changed regularly . best of luck to you !
The air coming out of the supply A/C vents should be 18 to 20 degrees cooler than the air going into the return air vent. As it gets hotter outside yes your A/C efficiency will drop.
the air temp blowing out should be at least 10 to 20 degree's cooler than the room temp-example/room temp 80 air coming out of the vents should be 70 to 60 as the room temp cools so should the air coming out of the vent-room temp 70 air coming out of the vents 60 to 50, sounds like to me that you have some other problem that they did not fix right,depending on room temp, it shouldn't take more than an hour or two to cool your place down
