As far as doing the work installing the duct work. It should not be a problem i did work for a HVAC company for 6 months some years back. I have a little HVAC back around. I am a FORD trained mechanic and have a EPA 609 certification. I do not have 608. I was just looking for a little help on tonage and duct sizing. I plan on doing a manual J and D. I just need to get the software load cal, to do it.
Thank you all for your post. Just wanted to clear up some thing.
