What Cool Calc does
Cool Calc operates a cloud-based SaaS platform that performs ACCA-approved Manual J (load calculation), Manual S (equipment selection), and Manual D (duct design) for residential HVAC design, delivered as a browser application accessible from any modern device without software installation. The product supports multiple input modalities — LiDAR scanning via an ARKit-powered free iOS app (Cool Calc Scan) that runs on iPhone 12 Pro and above, satellite map trace using Google Maps/Leaflet, floor plan upload for new construction, and free-draw/API for custom integrations — and integrates a Manual S equipment database covering 70+ major HVAC brands (Carrier, Trane, Lennox, Rheem, Goodman, Mitsubishi, LG, Daikin, among others). The architecture is built on a Level-3 HATEOAS REST API with CDN-hosted JavaScript/CSS libraries and server-side endpoints for OEM and distributor deployments, and outputs ACCA-compliant MJ8 reports usable for permitting, equipment ordering, and inspection.
The company monetizes through a self-serve, product-led growth model with three primary tiers: Pro at $50/user/mo (unlimited reports, LiDAR app, support), the forthcoming Pro+ at $250/user/mo (adding Proposal Builder, Backend CRM, API access, and ServiceTitan/House Call Pro/Zillow integrations), and a pay-per-project Personal plan at $45/project; academic access is provided free to instructors and trade schools. Customer base spans HVAC contractors, energy auditors, instructors and trade schools, and self-build homeowners, with claimed scale of 150k+ registered users and 1M+ projects created. Headcount is 1–10, the company is privately held under Distributor Corporation of New England (DCNE) in Malden, Massachusetts, and there is no disclosed external funding.

Cool Calc competitors and assessment
Company assessmentDirect peers
- Wrightsoft: Long-established developer of HVAC design software including Right-Suite Universal for Manual J/S/D, Block Load, and ACCA-aligned residential load calculations. Closest direct functional competitor to Cool Calc, but historically desktop-first.
- Elite Software: Developer of HVAC Design Suite and Manual J load calculation tools used by engineers and contractors. Direct competitor for ACCA-aligned residential HVAC load calculation, again primarily a desktop vendor.
- REM/Rate (Architectural Energy Corporation): Energy modeling and load calculation software widely used for residential energy audits, HERS ratings, and Manual J. Closely comparable in scope of work (load calcs, duct design, compliance) for energy auditors - a primary Cool Calc customer segment.
- EnergyGauge USA: Residential energy audit and rating software used for ENERGY STAR and code-compliance work. Overlaps directly with Cool Calc's Energy Auditor persona for Manual J and block-load workflows in retrofit and new-construction projects.
- HVAC-Calc: Web-based Manual J load calculation tool marketed to HVAC contractors and homeowners. Direct functional competitor in the cloud/online Manual J space where Cool Calc operates.
Broad incumbents
- ServiceTitan: Largest field-service management software for residential HVAC, plumbing, and electrical trades. A Cool Calc integration partner that controls the broader contractor workflow and could prioritize a native load calc tool over an integrated third party.
- HouseCall Pro: Field-service management platform for home service businesses including HVAC. Another Cool Calc integration partner with potential to bundle or replace third-party load-calculation tools through its own suite.
- IES (Integrated Environmental Solutions): Provider of building performance simulation software (IESVE) used for HVAC and energy analysis. Overlaps with Cool Calc's thermal-load calculation capability, scaled to whole-building and commercial use cases.
Emerging players
- Sefaira (Trimble): Cloud-based building performance and energy modeling tool now part of Trimble's design portfolio. Comparable architecture (cloud, HVAC/energy-oriented) but focused on commercial early-stage design rather than residential Manual J.
- cove.tool: Cloud energy and daylighting analysis platform for architects and MEP engineers during schematic design. Comparable cloud-based orientation and HVAC-adjacent performance modeling, though positioned upstream of Cool Calc in the design workflow.
