I recently put a two story addition on my house and the city is requiring me to fill out a Manual J worksheet. I hired a guy to do all the duct work and hook-up to my furance. I also asked him to fill out a Manual J worksheet. Unfortunately, he did not complete it right and the city has rejected it. Does anyone know how to do these calculations:
- Htg Load (Btuh)
- Clg Load (Btuh)
- Htg AVF (cfm)
- Clg AVF (cfm)
I have the square footage of each room in the house. I have the form in Excel if anyone wants me to email it to them. Any direction would help. Thank you so much in advance for your advice.
Thanks John
