Hi,
I have a question about the results I have from a manual J calculation. The info about the house was input (room sizes, type of construction, insulation or lack there of, window and door sizes and types, etc.). The report says the following:
Heating BTUH: 39,701
Cooling BTUH: 38,364
Sensible cooling: 33,902
Latent cooling: 4,461
CFM: 1,712
My house is in Houston, TX. My understanding is that these results indicate a 4 ton A/C system. Is the CFM calculated (1,712 cfm) representative of a 4 ton system? I thought there was 400 cfm/ton. Does the CFM on a manual J calculation influence the size of the A/C unit? Thanks.
