I just had a new 13 SEER 2 ton ac unit installed. New A coil and lines. The temperature drop is right around around 20 degrees, but the line temps make me wonder if it is fully charged. On my 30 year old 5 SEER unit when it worked properly, the large line was cold and the small line was hot to the touch. On the new unit the large line is cool, but not cold, and the small line is warm, but not hot. I guess I am trying to figure out if this is normal or if the installer might have shorted me on the refrigerant?
The house is cooling normally as the temp is 55 degrees coming out of the register on a 83 degree day, but I am worried if it will be able to cool the house on a 100 degree day. Should I call the guy back out? Is there anything else I can check to determine if it was done properly?
