About
Family-owned. US-based. Since 2017.
Scott Pingleton started LoadCalcs in 2017 after more than 25 years in the engineering field. Today it is a family team of ACCA-trained designers with more than 4,500 projects across 42 states and DC, working from Lancaster, Kentucky.

Why we exist
More building departments every year require load calculations, energy calculations and duct designs before they will issue a permit. Most contractors do not want a design department on payroll, and most homeowners do not know the rule of thumb their quote was based on.
We fill that gap. We match each project with the designer best suited to it, answer inquiries fast, and turn plans into documents that help permits issue and help installers build systems that work.
How we work
- Every designer is based in the United States. We never outsource overseas.
- Reach out during office hours and you’ll hear back within 30 minutes, whether it’s an email, text or call.
- New projects typically start within 3–5 business days, and 24-hour expedite is available once we have everything.
- We do not sell or install equipment, so we have no reason to upsize.
- Calculations follow ACCA Manuals J, S, D, N and T.
- We work in the industry’s standard tools: Wrightsoft for the Manuals, REScheck and EnergyGauge for energy code, Mitsubishi Diamond System Builder for VRF, and AutoCAD for drafting.
