TrueLoad gives electricians and heat pump installers a fast, defensible way to calculate existing service capacity — without setting foot on site.
The average U.S. home peaks at just 9.7 kW. A standard 100-amp service delivers 24 kW. That's a 60-amp gap — sitting there unused. Before you recommend a service upgrade, check the data.
Using NEC 220.87, TrueLoad uses actual measured demand data to prove the existing service is adequate. Data access and documentation have been the problem - until now.
Authorities Having Jurisdiction (AHJs) increasingly require a formal calculation before approving heat pump or EV charger installations on existing services. A verbal assurance isn't enough.
Recommending a service upgrade when one isn't needed adds thousands in cost and weeks of delay — and can kill a sale before it starts.
Access to data and clarity around how measured demand can be used has made this process highly overlooked. TrueLoad closes that gap.
TrueLoad walks you through the entire NEC 220.87 process — from requesting utility data to printing a report ready for the AHJ.
One project per job site. Enter the customer information and your details.
Enter service information such as the main breaker size and service voltage plus utility account information.
One click AMI data request. Your customer authorizes release of data and utility receives request.
Drag and drop the file from the utility — CSV, Excel, or XML. TrueLoad processes it automatically and identifies the peak demand.
List each piece of new equipment — heat pump, EV charger, water heater — and provide nameplate equipment demand.
PASS or FAIL is displayed immediately. Print a formatted report ready for permit submission or for your records.
TrueLoad is designed for licensed electricians and heat pump installers who need to document service adequacy quickly and reliably.
If you're adding a heat pump, EV charger, or other major load to an existing residential service and want to avoid an unnecessary service upgrade, this is the tool.
TrueLoad is free to use during the current beta period. Sign up, create a project, and have a report ready for the AHJ in under an hour.
