    Question Is Placement of HVAC Refrigerant Lines ok?

    I had a new central a/c installed yesterday and because I am disabled I was unable to check what the installers were doing. I am concerned about the placement of the Refrigerant lines though the company I used is well respected and should know what they are doing.

    The lines from my old A/C could not be used because the new unit has R410A refrigerant and the old unit was installed in 1987. The new lines were run into the basement between a window and a large heating duct and run along the heating duct to the furnace. The vent for the heating duct is directly below the lines and will blow hot air onto the lines and their insulation during the winter. As hot air rises I have no doubt they will receive a hot blast from the furnace when it is on. I think it is possible that the installers and salesman mistook the heating duct for a cold air duct as it is as large as a cold air duct.

    My question is whether this placement will affect the refrigerant lines in any negative way. If so, how do you think I should deal with this problem?

    thanks

    Yea some pics would help.
    Its doubtful the heat will hurt the lines. Some line sets are exposed to 150*F+ temps in some attics.

    How many times must one fix something before it is fixed?

    Thanks LOL I hope there won't be flames Here are the pictures. The last one that shows the lines going through the furnace room make me wonder too because they will be exposed to anyone going into that area to clean the electronic air filter and get at the water heater.

    On the other side of the heating duct is the electric panel that runs from the duct to the side wall. The original lines ran into the far side of the electric panel and along the wall/ceiling to the furnace room. The area was finished after the installation of the original AC in 1987. They said they couldn't use the old lines because of the difference in refrigerant and my research supports that. However, they did make a mess in the room and I'm concerned about the furnace room and crimping of the lines by someone who is in there to clean to air filter. Copper does distort very easily IMHO.
    Should I call them and raise H**?

    What was written in the proposal? You did get one? Chances are, if it wasn't in the proposal,it's not gonna get done as a no charge.

    I would have looked for another way to run that line set, just for appearance.
    The heat won't hurt it.
    But that, well, that just ain't right.
