Passed the course test first try. This course is very informative and I highly recommend it.

Congratulations! I just finished this course as well and I’m about to take the exam as we speak. This is actually the final course before I can take the exam both with interNACHI but also with the state of Arizona. Overall I am very pleased with the amount of training I have been able to receive here.

Hello Sir,
I have seen Mr Gromicko on youtube recommending the FLIR C2. It looks like it is roughly the size of a phone and he said it worked great. I’ve seen some bigger, more expensive cameras but apparently they are not necessary.
About checking for insulation in existing wall cavity, that is beyond standard of practice for Nachi. But, if the homeowner wanted to know. What is the best way to handle that? Would the inspector defer the homeowner to a professional contractor? or would the inspector verify that there is insulation and charge the homeowner a separate rate or do a change order to extend the service with additional cost?
I am reading about crawl spaces. When an unvented crawl space is below grade is the drainage method to use a sump-pump?
Other question, how do you mechanically ventilate a unventilated crawl space?–is that with a stand alone ductless split unit?
Starting the Course
I don’t see the reason to install a heat recovery system in a residential house because that would take up too much attic space or the house would have to be build with more sq footage to accommodate. It is simpler to install a split system with a and do all the energy recovery through the air handler by installing a bypass between the supply and return and tapping into that bypass with a duct that uses a gravity damper or electronically and take fresh air from outside of the building. The outside air duct would be tapping the bypass downstream of the bypass damper. And use a zone system to feed air into each of the rooms and spaces throughout the house…

This course appears to have a ton of info. Cant wait to get started.
so far its been pretty straight forward. nothing really challenging, but more good steps for getting a game plane for future inspections.
it really wasn’t bad, easy to get through. a good tool for sure!
interior goes over some stuff that is usually on the back burner! good info on here!
Thanks. Just getting back into it. I completed 90% of my ICC courses at a local college. I messed around and got a good paying job and never returned to it. These courses should be a great refresher and might even get me energized to finish my ICC certs after I pass this exam.
Im interested to hear some success stories from NACHI students like myself.
nice to have old house vs new house construction comparisons regarding hvac, insulation, construction materials, etc. big dfference between vinyl-wrapped cardboard laminate on commercial pine with engineered trusses and nail pates, and rough-cut timbers and hardwood siding using nails the size of a #2 pencil, with lathe boards and wet plaster interior.
what year did attic cards for insulation become standard?
regarding egress doors, what year did 32" become the standard width and what about houses built before then with non-standard door sizes? Just part of having an old house, or defect in need of correction?
Also, handrails … what do you do if they come off in your hand? we’re not supposed to cause damage–just set it down and write it up as a defect? be glad it was you testing it and not someone falling on it?
what’s the sketchiest handrail you’ve come across?
