I just installed a new inside unit ( 3 ton split) It still cycle's the same and I'm getting a 17.5 deg. temp difference.When the unit start's up and shut's down there is alot of loud gurgling,the smaller line jerk's and the coil doesn't get cold all the way to the top. Were the line's evacuated properly -could it be air bound. Maybe the inside coil doesn't match. What would cause this side affect. The previous coil was old (outdated)and clogged in section's I couldn't clean but I still got a 20 deg.temp.diff. and it never made that much noise after it started or shut down. I could hear the hissing as the gas/liquid ? settled but it was never such an ATTENTION GETTER. I'm mad as h*** because I just don't think it was done right. ??????????????????

was a txv installed on your new coil? also is this system a 410 or 22 system? and was the outdoor unit also replace?
