Hi, I am a new member. Are there any answers (correct) to the HVAC test questions?? Are they from the NATE certification test? Any thoughts on the NATE certification? I thought these questions were pretty good, maybe the more ambigious ones were to make you think a bit, like this one:
4. A typical induced draft furnace uses a blower-off delay in the cooling mode to:
a. Increase the efficiency of the system (wrong, but let me adjust my "Cold" anticipator just in case)
b. Air wash the coil on shutdown (what's an air wash??)
c. Minimize dehumidification at the coil (wrong..maybe, what's he trying to say?)
d. Prevent blowing moisture off the coil on shut off (does this happen?)
Well I thought they did it to get the moisture out. I was pretty smart 'til I got to that one, now I'm afraid to go on, I could get obsessive about finding the RIGHT answer and lose sleep, sanity is gone already. Anyway I would like to hear your opinions on the NATE Cert. Thanks...
