Copper line freezing up from HP to handler
We had our ICP 3.5 ton HP replaced in January 2010.
The air handler in our crawl space was not replaced.
We have had 88 degree days and I switched it from heat to AC.
The first day it cooled quickly and seemed to work fine.
Last night we noticed the air from the vents was not blowing as strong as it used to and the HP was continuously running yet the temp in the house remained the same.
This morning I went outside and in the crawlspace and noticed the copper line that connects the HP to the air handler was iced up where insulation was missing. I shut down the unit as to not cause any more icing.
Here are some pictures. Does any one know what could be causing it?
Thanks in advance!
Here is the copper pipe exiting the air handler in the crawl space. It is covered in frost.
Below is the copper pipe exiting the Outside Heat pump. It is also covered in frost.
