Im with Dash, then I cant believe the number of people hung up on supply air temperature without considering the latent load.
To the OP, you bought a system to cool your home, not give you a specific vent temperature. The higher efficiency units run with a slightly warmer coil thus a slightly higher supply air temperature. Latent load takes away temperature drop, regardless of the efficiency. These coils are larger physicly so they can do the same BTU removal at a warmer coil. Each square inch of coil surface will be warmer, but the amount of square inches is increased.
Pardon my frankness here but, the sooner you get off wanting a specific supply air temperautre and looking for a comfortable setting within your home the better off you will be. Also you can piss on the same temperature setting because the RH is probably not the same, it may be higher or lower and that will affect the comfort level at a given sprcific temperature.
Once you get the home dried out, you may very well see similar temperatures within a degree or two of your previous system.
Sorry I haven't been able to answer your questions but the techs were worse than me! They wouldn't answer any questions. Anyway, it's 100 degrees outside and house is a cool 77degrees so I guess I'll just have to be happy with that. Too broke to hire anymore techs!!! I just hope my electric bill won't leave me bankrupt!!
Originally posted by madeinusa I also believe you can file a complaint through the State of Texas licensing board on matters such as this. They will make sure people like this are fined and put out of business if not licensed.
Shotgun approach ?
Seems like this thread may be discussed through July, 2006.

Originally posted by joe 40 I know I shouldn't worry but if these techs don't know what they're doing I must find out what's wrong.
Techs left and guess what? They left pressures at
95-290. They also added extra freon. O.k.
"They probably should have removed refrigerant!"
They did not evacuate the system it could have air in the system; also there could be solder restrictions!
Print the linked page and give them a copy!
I know I'm no
a/c genious but aren't you suppose to (evacuate) vacuum the system a few hours before? Surprise, they didn't!! I also found out from another source(a/c tech) that there is a good chance they could have messed up the compressor. [Doubt that] He told me to ask for a new system but I don't think they will give me one. [Not necessary] I personally want my money back!! It's been three weeks, and system still not working properly. [Your system can be made to work!]
Personally, I think these techs aren't certified or licensed! Wife says they were still wet from crossing the river!!(Rio Grande River) [Ha]
Temp set at 75degrees, but vents only 66degrees. 9 to 10 degrees difference. Please anyone think this is normal?
NO, that is not normal at that humidity level.
(Techs left and guess what? They left pressures at
95-290.) Presures getting way too high after adding charge!
I believe, if it was real hot in the house and the airflow is set too high, they may have seriously overcharged the system when they intalled it. Print - Read my linked page!

Originally posted by joe 40 9:40 at night and house is set at 75degrees like they told me to do. It has reached it and it turns on and off, my problem is I know this system is not set up correctly. I almost sure they overcharged it cause of the pressures. Owner of company will come down tommorrow( so he says.) How do I explain to them that even if the house seems cool system is not working correctly.
Can anyone tell me what subcooling is?
I know they have added R-22 like 4 times and not once, not even when they installed it was it vacuumed. Could it have air in the line? (contaminates)
Maybe I'll become an a/c tech after this!!! Sure am learning alot but they think they know more!!!!!!!!
So why don't they make it work!
