Old school filter changes (and fixed income retirees saving $ !)
We've gone through the couple of air handler filters that were on hand from the previous owner and I went to purchase a box of what I usually get, sized for the intake here in Florida, and ran into sticker shock (I'm assuming the virus in 2020 is the cause). I decided to install a manometer, which measures pressure differential, which I have installed and used over the years in almost every building I worked in that had air handlers. I went old school instead of the newer electronic ones. The filter comes with some handy information listed on the frame which I'll use to determine when to change out the filter, instead of being told by my Nest thermostat when I should change it. The Nest is better than just a set date, as it uses hours the air handler has run, but the manometer goes one step further and shows how "dirty" the filter actually is. If all goes as plan, and my experience tells me it should, then the manometer will pay for itself in a few months, ass...
