      Carrier chiller I get to work on

      We have a client with three of these old Carriers 30HR140-600C. A few years back we replaced the original controllers with Honeywell T775s w/expansion modules. Also converted to 407C. Some leaks, some TXV heads, over the years, still running strong. These are about as big as we go as a company. No centrifugal work. These run like sewing machines. Very noisy sewing machines! I do enjoy working on them.

      • About me; 65 years old. Been HVAC wrenching for over 40 years after serving in the USN as a BT 78-83. May retire in a few years. For now, I still love the trade and the daily challenges I get to solve. From boilers, refrigeration, small systems and large. If I don’t know, I know how to figure it out (most times).

      • Mannn! You’ve probably forgotten more than I know! I’m 37 & grew up in the trade (family owns a hvac/r company in Florida).
        Never thought about doing some office work, or do you just prefer working with your hands?

        • @checkmate89 I do some office stuff from home when I take “days off” to let the other guys get their hours in. I’ve always been a stickler about equipment lists, schedules, parts ordering and stuff like that. I still get out and do service when we are busy and train others on the boilers & chillers when the inspections come around. I did try office once many years ago. Lasted about 2 weeks. Nope, not for me.

        • Oh yeah, those are fun. Love those OEM controllers.
