For reference my PB allowed me to buy my own equipment, not wanting to roll the dice with whatever was available at build time. He has the installation costs built into the pool price so I don’t know what he is charging for hookup, but my 3HP VS pump was $1500, my SWG/controller was $1500 and the 500 sq ft filter was $1875. All plus tax of course. $3k is about what I was expecting if I went with a 400K heater.
