These may be simple questions.
#1) I just recently had a new condensor coil replaced for AC unit, plus installed new attic insulation. My HVAC unit is in my attic. After the install, I noticed that the air was coming out the vents much stronger than before. I thought this was a good thing, especially since I live in Texas. However I noticed that in the kitchen, dining and utility rooms, which are all located on the other end of my house, the air was barely coming out throught the vents. The degree is very noticeable and as in the utility room there is no air coming out. Again, didn't have this problem before install. I spoke to the installer on the phone about the situation and he denied that his work had anything to do with it. He said he would report it to company owner. I haven't heard from them yet and will be calling this week. I would like this repaired before the hot texas summer gets here. Due to the uneven air distribution, when the temperture rises, I'm sure the differences in room temperture will be more pronounced. My question, is it possible between the install and adding insulation in the attic that these activites in some way may be the culprit?
#2)Take a look at the pics I've included. Does cold air suppose to come from the plastic pipe sitting vertically (straight up)? When the A/C unit is running, a strong pressure of cold air exits from this pipe. I don't understand, my older unit didn't have this. Why is the air coming out and why is it cold??? It's like I'm trying to cool my attic.
Any explanations by you pros would be appreciated. BTW here in Dallas, I've dealt with some HVAC people who have just been plain dishonest and I'm sure you guys would not want representing your industry.
