All in all, I think it was a good deal. Turns out I had a wide open vent at my kitchen hood vent. I plan to replace the entire hood and install an internal damper. Currently I have removed the fan and just taped off the open 8" duct. This duct was responsible for the previous posts super high CFM in the leak test.
This new test I believe is more accurate result of my "loose" house which really was not that bad. This tested value was 2400 CFM @ 50 Pascals. Not too far from an Energy Star compliant home! We shall see if I get there after all sealing is complete.
Both my heat pumps were leak tested at a 25 Pascals and found to be leaking at around 250CFM each which when divided by their 4 Tonnage size results in the calculated loss of about 14% (anything over 20% is considered faulty)
For more details:

Bedroom Unit: 224 CFM@25Pascals / 1600 = 14% leakage
Kitchen Unit: 214 CFM@25Pascals /1600 = 13.4% leakage
Sealed up many openings in attic and all around the chimney:
12 Canned Lights Throughout House
Chimney Perimeter Had Clear Openings to Living Room
Although Not Energy Improvement, Possible Leaks Prevented At Roof Openings
Bathroom Fans Too
Filled up the attic with CertainTEED blown fiberglass to a height of 22 inches getting a maximum of R60.
Filling In Around Chimney Area - Voids of Chimney Sides Also Filled In.
The workers said this was a really big house and they used 6 cans of foam sealant when they normally use 1 or 2. They worked until about 8pm and had to close up before finishing. They will need to come back to "pooky" seal up the rooftop AC plenums and perform their final pressure tests to verify the sealing improvement to the house and ducts.
