Hey Ed, Are There Parts of the Country Where They Have Air So Dry That We Never See Water Collecting in the Drain Pan of the Indoor Coil?


In This Edition of “Hey Ed,” Ed Discusses if There Are Parts of the Country With Air So Dry That We Never See Water Collecting in the Drain Pan of the Indoor Coil

Hey Ed, are there parts of the country where they have air so dry that we never see water collecting in the drain pan of the indoor coil? Absolutely. There are parts of the country that we reference as arid or dry sections. I once heard somebody say if you use the term arid, they think you're talking about a brand of deodorant. I think that guy is kind of a knucklehead, but we have areas such as where you live in Arizona, Alyx, where your air conditioner will run for extended periods of time. No water coming out of the white pipe. Another way we describe that is you're doing 100% sensible work, and that is a very common thing, but one of the things that I'm not familiar with is an area that is so arid that we can install a traditional direct expansion cooling system that doesn't have a drain on it. So, for that reason, I'm always going to make sure that I install a proper drain and emergency pan or some mechanism that if the drain fails to work properly, the system will shut off, and that's the way I see it.
