Thermentor is a new web-based application that helps HVAC contractors size heat pumps using real energy data—not assumptions. Instead of relying on time-consuming methods measuring every window and door, Thermentor analyzes a home’s utility bills and local weather patterns to calculate heating and cooling loads. The result is a clear, data-backed report that shows how much energy goes into comfort—and how a new system will perform.

Currently free to use, Thermentor gives contractors a powerful way to build trust with homeowners. It predicts utility bill impacts, identifies available rebates, and helps explain why a recommended system size makes sense. That transparency helps reduce objections, avoid callbacks, and close more confident sales.

Thermentor is web-based and works on any device. Contractors can walk through the process with homeowners or send a link in advance. It’s designed to make load calculations more accessible, accurate, and actionable.
