Was very nice and helpful although I feel as though I should not have been charged a $35 fee being he could not install the filter because we had to reroute pipe to put filter in not his fault but could have been notified that the pictures they had did not show the pipe routed that way and they were not gonna reroute for free being it was changed after they installed unit. Had more problems after he left and had to file down some screws so the filter would fit in all the way because the unit table had screws that were too long to let filter push in all the way. All in all the technician was nice and helpful within his means of service. I think the company could have maybe handled it better instead of sending him out knowing they were gonna have to charge me a few of $90 plus $69 to reroute pipe when I was told the fee was only gonna be $35. They were able to compare picture that I sent and ones they had before making the service call could have saved me $35 witch some may think it is not much but these days it's alot! Won't be using y'all again. Like I said nothing to do with tech he was great!
