the technician didn't even know what an intake pipe was.
told me the bacteria fighter, which they installed, had gone out of business so they don't make any bulbs for it anymore. WRONG! but of course i could purchase a new system, which was a better company, etc. I'm sure they said the same kind of sales pitch when they installed the original one. Anyways, my bulb is ordered from the out of business company. LOL.
Then we discussed the outtake and how it was not code, which he didn't agree with me even though other furnace people and an inspector had stated so. after many phone calls to the engineer, it finally came around to yes, it was against code. the engineer had to be researching it as well. with every phone call, he kept getting closer to what i had already determined. but of course it was code back when they installed it. I beg to differ. but that's for another day.
then they also said that cutting the intake pipe just above the ceiling is common practice. allowing all the crap, dust, mice, etc. to fall into the intake pipe. most furnace people tell me they have never seen it cut off above the ceiling. ABSOLUTELY RIDICULOUS BULLCRAP.
NEVER USE THESE PEOPLE!
