Mismatched A/C equipment

[bigdog]

Hi Jerry
When did the new rules affecting replacing one of the 2 pieces in a split system go into affect. I'm thinking 2007 code change.
Is it in the energy code 13-607.AB.3.1.1?

Thanks Jerry for that extensive explanation.
Not to put to fine of a point on it but I know I have seen another version somewhere (obviously not code) that was more to the point and stated ( for those who have trouble comprehending the seemingly convoluted ramblings of those who write this stuff ) that mismatched components had to be compatible based upon submitted manufacturers specs or use an engineers letter.

Upon rereading Chapter 13 607 it states "from different manufacturers" leading one (myself included) to believe that using the same manufacturer when replacing individual components would exempt one from this requirement.

On another note most of the links on your site are not working for me...like I just tried to go to the FL building code online but it didn't work.

I'll check the links, thanks.

The simple answer to your question is that 3rd Party certification is required for ALL a/c equipment installed in Florida, new installs and replacement installs, and whether or not the equipment is mismatched or is matched.

The above simple answer does not provide supporting documentation which answers questions not asked.
