Manual J: Help me design my HVAC system, please
Help me please , I am going insane….. Looking for help sizing and designing Hvac mini split systems in my new construction…. Had Manual J done by 3rd party. Home also has 3/4” XPS insulation around exterior…. The entire house has 2” closed cell and additional open cell in roof to fill stud cavity .. I also installed 3” Rockwool in all wall cavity’s. Have have come back with 1 billion cans of spray foam and Liquid zip sealing up house. No blower door test yet waiting on door installs. My confusion come from zoning of minisplits … what do you guys think is most efficient way? If you need additional Manual J papers please let me know. Thanks guys.
