Neighbor guy ask me to "look" at his hvac system that another guy put in last year. The lineset is about 3'-4' long. I am thinking the minimum is 8'. Is that correct?
while I was there they told me their idiot light was blinking 8 times. The guy who installed the system had been back to install a new board. I looked at the instructions from the board as well as the diagnostics on the door, and the diagnostic code showed up to 7 blinks, no 8.
I gave my neighbor my hourly rate and made an appointment to go back. I don't need an idiot light to find the problem. But I am curious about the 8th blink. Any ideas?
