The PDS Technicians that resolved my heating issue were well trained, very professional and very personable. There was no big push to replace my older unit like another well known company attempted to do earlier in the year(Yes one of the Techs did mention upgrading and total cost of a new unit). The entire process, from diagnosis to repair was thoroughly explained to me, and completed in a timely manner. My hats off to Vincent Gentry, Lorenzo Castillo, Jesse Villasenor and Brett Griffith. PDS will be my “Go To” in the future with any related issue that pops up
