Performed maintenance on gas pack, system working within manufacture specifications, and found no issues. However, homeowner seems to be having some air distribution issues. We did do the ductwork here and I set up an appointment to have air balancing done for homeowner. Also set homeowner up on renewal for maintenance agreement so that doesn’t lapse. Homeowner said that they do have allergies and we’re open to hearing about the Reme halo so I gave them some information and they want to do a little homework before they pull the trigger but seemed very interested. Unit running at departure with a 23° temperature differential.
