Hi
I am building a house and getting quotes on evaporative cooling. Have two quotes in front of me, both for Brivas systems and seven outlets. However one is offering largest model (L63) plus gold 75mm ducting. The other offers me L43 model (and says the capacity of machine will be 12% above need) plus 50mm silver ducting. There is approx $800 difference between 2 quotes - should I spend the extra for larger machine?
Thanks
