Actually Pear I really could care less about your opinion of my work because it is obvious you know nothing. Lets see what kind of work you do then we will talk.
As too a 2-year old R-410A system having a PSC motor or an ICM motor WTF. What does the type of refrigerant used have to do with the type of blower? Most jobs with R-410A don't have VS blowers. The VS motor is not a prerequisite to having or using R-410A. I called you an idiot not I said don't post idiotic responses. Making a guess at a problem with little information makes you a hack not a pro.
So little eddy go home suck on your thumb clean out your dirty yellow diapers and come back when you can play with the men.
