Greetings all.

I am acting as the general on our new house (obviously I hired a fool :laughing. I am a reasonable DIYer and was wondering about installing the AC/heat pump myself. The firm I have looked at offers Rheem & Goodman units and can do the Manual J calcs as well as the duct design, from my plans. For what it's worth, this is a 2500sqft South Texas ICF house with foam deck insulation, metal roof & very good windows, it should be very tight. The air handler will install in a central interior room, so only thing in the attic will be the ducting. I am looking at a main run of hard duct with flex off to each register. I know that all line connections and start up must be performed by a certified HVAC person for warranty & gov reasons. Are there any reasons I should not do this?

BTW - This is out in the county, so there are no inspections required.

Only thing to keep in mind. is the less profit a company makes. The less likely they are to make a long drive for something you think should be covered by warranty.

HFC's are not restricted by teh EPA like CFCs or HCFCs are. So you can do all your own work as far as the EPA is concerned. Manufacturer may void warrant though.

OK thanks. I really wouldn't trust my soldering that much and I think most companies require a qualified HVAC person to do the connections and start up to validate the warranty.
