My all-in price, including Glacier GPC-210, was around $3k. I think the chiller was in the $2k range, so about $1k for installation, including actuators and electrical work to add chiller to control panel. That’s all from about 5 years ago.
BTW, I think you’ll enjoy the chiller. I’m in Flower Mound and it has made a HUGE difference in water temps. I just checked, and my current pool temp is 79. Prior to the Glacier, water would get to mid-90s by this time of year.
