Raynor Services is a leading electrical and HVAC contractor serving southern New Jersey for more than 30 years. Operating a ten-truck fleet out of Mount Holly, the company covers electrical, heating, cooling, generators, and water heaters services across Burlington, Camden, Atlantic, and Ocean counties. With expertise across both electrical and HVAC systems, Raynor is a trusted one-stop shop helping homeowners with everything from everyday service needs to major upgrades and electrification projects.
As EV charger and heat pump work grew, load calculations became a part of nearly every estimate. The team was completing them by hand, which was a slow manual process at that volume. They adopted Kopperfield to run NEC load calculations on site, produce permit-ready documentation, and show homeowners the capacity math before quoting the job.

Winning more jobs with on-site load calculations
The ability to complete load calculations quickly is important, but Raynor’s biggest win is being able to create them directly with the homeowner as part of the sales process.
With Kopperfield, the team can complete a load calculation during their visit and immediately show homeowners why a service upgrade is or isn’t needed. Instead of relying on a verbal explanation, Raynor can provide visual proof of the home’s electrical capacity, making technical recommendations easier to understand and helping homeowners feel confident in the solution.
Having a professional, accurate load calculation report ready during the estimate helps Raynor build credibility, stand out from other contractors, and give homeowners confidence in their recommendation. Because Kopperfield is mobile-friendly, the team can generate documentation in the field, answer questions in real time, and help customers make decisions while they are on-site.
For Raynor, load calculations have become more than a technical requirement, they have come a sales tool to win more jobs.
“It sets us apart from other companies. We can do the load calc with the customer and show them right on the spot exactly why they do or don't need a service upgrade on their home."

Permit-ready load calculations for inspectors
Kevin has been a project manager at Raynor for about seven years. He can point to exactly when load calculations went from a routine task to a bottleneck in their workflow.
As EV charger installations increased, so did the number of load calculations required for each project. The same applied to heat pumps, and mini-splits, where verifying available electrical capacity became an essential step before moving forward with an installation.
Time wasn't the only cost. Load calculations are reviewed by the local authority having jurisdiction (AHJ) or township, and each municipality has its own documentation requirements. Every revision meant additional paperwork and delays before work could move forward.
Consistent, inspector-ready reports help reduce that back and forth by providing a standardized format for permit submissions. Through Kopperfield’s Inspector Program, many inspectors and AHJs are already familiar with Kopperfield's reports, helping create a smoother review process for contractors. Across all submissions generated with Kopperfield, 99% pass permit review on the first submission.
“It gives you a very professional load calculation to submit to the township. We never have any issues with them bouncing back."
