FAQ
What information do you need from me to start the project?
To begin, please provide your architectural floor plans or sketches with dimensions. I will also need your project's location (zip code/city) to get accurate climate data, insulation details (R values for walls/roofs), and window specifications (U factor and SHGC).
Can you modify the design if my local building department requests changes?
Yes, modifications based on official feedback from your local building department or plans examiners are fully covered under the gig revisions. I will adjust the calculations or drawings to ensure your project passes inspection.
Do you use ACCA approved software for the load calculations?
Absolutely. I use industry standard engineering software like Carrier HAP and Elite/Wrightsoft. You will receive professional, official calculation reports that clearly outline the heating/cooling loads and equipment sizing for your project.
