I just purchased a homewith a 23 year old Lennox. I plan on having it serviced and hope to get through a summer so that along with a load calculation I can geta properly sized unit. I want to get 2 stage either Carrier or Trane. Is either one of these quieter that the other? House does not have basement and Air Handler is located in a main floor closet.
Model number of condencer is HP16-4110-9P. Can you tell me what size this is?
