My installer finished my HVAC yesterday. I had a new furnace, coil and A/C unit installed. My question is he didn't seem sure of himself bwhen it came to the Txv valve. He placed the bulb on the suction line going vertically b/c there really wasn't any place horizontally. I looked at the instructions and the picture show horizontally. Does it matter? Do I have him come back and run a longer straight pipe out before elbowing up to get it on.
