If you have an evaporative cooler and an air conditioner running at the same time they are counter productive with each other. The evaporative cooler is putting moisture in and the AC is taking the moisture out. My dad was a home builder in Phoenix. That's what he told me. You might research it. Personally don't have any knowledge of how that all works.
@@nettp7773 We have the option of only turning on the fan of the evaporative cooler - but at times it’s very dry here in Arizona so I want my humidity to fall between 45 and 55% - then I will want water in the air - I’ll turn on the water pump in the cooler. It’s just a small one anyway. Thank you for commenting.
