Upon my arrival in Giddings, I found that the A/C system does have a very rusty secondary pan, and a dirty indoor coil. Gave customer options he choose HK2A HF6A. Will get with Jacob so he can order a second pan. We will need to fix the Darin line , install a new p-trap, a primary safety switch, install a ball valve on the secondary pan. Will need to picked up sprayer to bring to job, 2 techs 3 hours. customer is only available only on Mondays and Fridays, do not schedule in after noon attic is hot.
