THIS IS A CONTRACTOR MODELING SPREADSHEET" (OTC),
A COMPLIANT ALTERNATIVE METHOD TO
ACCA'S MANUAL S, FOR RESIDENTIAL HVAC 
EQUIPMENT SELECTION
* Patent Pending

Get results, with no Expanded Data charts needed!

1. Why would I need "Manual S"?

ICC code dictates it.

2. What's it for?

It's used AFTER the load calculation, to select equipment.

3. Why not just use the model # ?

Model numbers only roughly give a clue on BTU capacity.

5. Usn't AHRI giving the capacity?

AHRI rating is nominal, like a MPG sticker on a car.

4. Who's going to know anyway?

The home occupant may not get the correct size unit and comfort. This is really just  the 2nd half of load calculation.

5. I think I have this software already, why pay for this now?

BECAUSE NOBODY DOES THIS BETTER! We did it FIRST here. We have found current popular software is time consuming, over complex to use, missing pieces of ACCA's guidelines, and not compliant to their manual. Some crudely added the feature recently by R&D (rip-off & duplicate), just to compete with OTC. (They are an insult to ACCA's intent, and are missing the best features of Manual S) 

This method was presented at the 2019 HVAC Excellence National Educators Conference, with good reviews. Click star to see PowerPoint presentation:

5. Why did you make this program to require Microsoft Excel?

We would love to create this as a standalone product, but we have not found an economical and efficient utility to make that happen yet. (would appreciate any leads on that!)
