actually the observer t stat on ICP equipment does display error messages saying "Main limit open" or "Flame not Proven" and so on.

Dont you guys love those service calls where you get there and everything checks out until you notice the extremely new and clean filter in the return or the EXTREMELY dirty one sitting next to the unit then you figure out it was over temping. I guess that after the customer gets off the phone wanting you to come over they go downstairs and change the filter quick so you cant call them on it. kinda like when you went to the dentist as a kid and brushed your teeth reeeeeal well for the first time in weeks thinking you would fool the dentist into thinking that you had been doing that for the past few months. but hay i can see how its an easy thing to forget or put off

SOOO !When all is said and done!! .changing a 4" thick filter, is no different than changing the ever popular 1" thick filter, for length of time periods. . AM i right or wrong $1.49? vs $25.00. Lord!!! i could stack them filters up with 4" filters for under $10.00. Am i thinking wrong on this.Please don't get to far into depth on the "vitals." i'm just a dumb licensed retired plumber. thanks fellas bob s
ps my final on this would be Is it a good idea to use 4 chaeper filters to get the same ait quality as it does this expensive 4" filter. I would like to go with the first 4 separate 1"filteres opposed to one 4" filter, man i hope i worded this right let me her ya guys bob s

4-1" fiberglass see through air filters in series will have about a .28" PD at an air velocity of 300 FPM. 4-1" MERV 7 pleated air filters in series will have about a .36" PD at 300 FPM. A 4" media filter MERV 8 will be from .17 to .23" PD at 300 FPM. Last longer, and be easier on your blower motor and A/C.

In layman/dumb plumber terms if you stack 4 filters it will restrict the air flow so much that your furnace will overheat and die a premature death. The reason they have 4 and 5 inch filters is that the acordian shape and length of the pleats and shape of them allows air thru easier and has more surface area and will last longer. By the way do all plumbers have butt crack?

I use this method, right before the heating season when I PM the equipment for winter operation I change the filters.
Right before cooling season I do the PM and change the filters.
Weather they look like they need it or not. It comes out to just about every 6 months. It's worth it for the cleanliness of your air and systems.

What's a few bucks to be sure? Now I know quite a few people don't have Summer/ Winter Seasons so I suggest checking them every three months if the unit runs hard most of the year.
