A hissing sound that lasts 30-45 seconds is coming from the lower of the 2 a/c lines that enter the firewall.. The unit is cooling 33 degrees below ambient and shows 30-35 lbs pressure. Is the hissing sound indicative of a problem?

This hissing sound is normal as the ac system equalizes. No problem
