Condensate drain hose lying on ground outside

The HVAC installers originally ran the flexible condensate hose 20 feet through my basement to the outside of the house and left 3-4 feet of the flexible hose lying flat in the garden before it terminated. They did that rather than going just few feet from the furnace into the standpipe where my washer drains. That was 2 years ago here in TN. Two days ago the furnace shut down because the 3-4 feet of hose lying in the garden, although insulated, froze solid in the garden because there was no slope in the hose to make it drain, the water just sat in the hose when the pump wasn’t running.

The tech from the original company came, cut off the length of hose outside the house and pulled the 16 feet of hose back into the basement and ran it into the standpipe for the laundry. They charged me $241 despite my having purchased an extra maintenance protection plan with the unit. From everything I’ve watched and read online now about the installation and care of condensate drain lines it seems clear to me that there shouldn’t have been 3-4 feet of hose lying in the garden in the first place. I think the freeze issue was caused by the HVAC company making the drain hose highly susceptible to freezing instead of terminating the drain hose just outside the wall where the condensate would have fallen to the ground below. Am I wrong? Thanks!

The original installers did a poor job and possibly one not up to the current building code standards. I have a feeling the installers were lazy and didn't expect the type of cold weather you're having now. Any and all lines that drain water should be pitched properly to their terminus.
