Hello all, I've been researching new HVAC system for one of the zones of my home in Dallas, TX. Good thing, as my AC went out today, so will likely replace unless it's a cheap fix. Current equipment is 3.5 ton, 15 years old, 10 SEER, R22.

Did a load calc for the area and it came out at just over 3 tons (39,581 BTU heat gain). Please look at systems proposed and let me know which you would recommend, given that system 2 is about 15% more than system 1. Could also go with a comparable Rheem system for about the same as system 1.

Both systems would include same install details including all new duct work, but use existing line set.

Liked both contractors, and both come highly recommended, so would be comfortable with either. Thanks in advance for your thoughts, as I'll likely need to pull the trigger on this in the next couple of days.
