ThermoGrid was built specifically for residential HVAC contractors and continues to carry that DNA as part of ECI Software Solutions. Where horizontal FSMs try to flex across every trade, ThermoGrid is opinionated about how HVAC shops should dispatch, price, and measure performance. Its Smart Dispatch engine factors in real-time technician location, skill proficiencies, and performance rankings so the right tech, not just the closest one, is sent on each call. That performance-weighted dispatch is particularly useful for HVAC shops that want their top closers in front of the highest-value replacement opportunities.

The platform bundles scheduling, dispatching, invoicing, a flat-rate price book, inventory, CRM, and KPI dashboards into one system. Technicians use a mobile and web app to access job details, upload photos, collect signatures, generate invoices, present financing options, and process payments in the field, including offline support for areas with poor cell coverage. Built-in VoIP, payment processing, and marketing tools reduce the number of point solutions HVAC owners need to assemble separately.

ThermoGrid integrates with QuickBooks to sync invoices, payments, and deferred revenue for maintenance agreements, and the ECI ownership opens up cross-sell integrations with other ECI trade products. Reviewers consistently praise responsive customer support and the ability to customize calendars, job categories, and workflows. The trade-off is a narrower native integration catalog than larger FSMs and occasional rough edges in the QuickBooks sync, making ThermoGrid best suited for residential HVAC shops that want an HVAC-opinionated system rather than a generic FSM.
