The entire HVAC unit suddenly quit working, the rig is out of Manf. Warranty and we weren't exactly sure what was wrong. Called several other techs to come out and there was a long wait list and most had very high call out rates and wanted payment up front. When I explained to Chris the situation, he came the very next day, inspected the unit and found that that the HVAC unit was improperly wired going to the thermostat(only 2 wires when there should have been 4), Chris took pictures. Extended warranty wouldn't cover it because it was a Manf. Defect, so Chris tried getting anyone from PUMA to talk to him and as y'all know that's almost impossible, together we finally got to the right people (Engineer and Gretchen in warranty dept.) , Chris was trying to get schematics of the wiring, he worked with the engineer who sent him the specs which confirmed his suspicion on the wiring. Gretchen in warranty wasn't wanting to cover it despite it being a Manf. Issue, eventually after several emails she agreed to allow the work to be done with PUMA picking up the bill for it. Chris was extremely professional, responds very quickly to texts, phone calls and emails from me and PUMA. Once everything was finalized with PUMA Chris came right out the next day for the unit properly wired and running, from what I understand (from my son) it's running great, as a matter of fact he said he woke up sweating 😂. I highly recommend Chris, very easy and fair person to work with. I appreciate everything you did for my son and his unit. Will use again if the need arises.
