1 in 5 Heat Pump Jobs Is at Risk Today
Heat pump installers lose up to 20% of jobs because customer electrical panels are too tight or appear at risk of exceeding capacity. Traditional calculations are conservative, often forcing unnecessary and expensive service upgrades.

Step 1. Easy Install
Install clip-on sensors around the panel mains and connect the device to the internet. Stepwise continuously measures actual home electrical demand, not conservative nameplate estimates, and ensures the heat pump operates within panel limits.
Step 2. Inspection Ready Report
Stepwise generates a clear, code-aligned load report that you share with the electrical inspector prior to inspection. The report shows real-world capacity data that supports installing the heat pump without a service upgrade.
Guaranteed to meet NEC
We can avoid the service upgrade because of section 750.C Load Management, which enables products like Stepwise Tap to eliminate the need for a load calculation.
If the installation doesn’t pass inspection, we refund you and pay for the service upgrade.
