Regret Hot: Cooling System

Work faster on every installation, service call, and project handoff with a premium offline-first HVAC toolkit built for installers and engineers. Regret Hot: Cooling System brings engineering calculators, vacuum protocols, project records, reference data, and export-ready documentation into one professional iPhone app.

Use it on site, in the workshop, or while traveling between jobs. Your core data stays on device, so you can keep working even with no signal, then sync or export when you are ready.

KEY FEATURES

• Engineering calculators - estimate cooling capacity, route length, superheat, subcooling, and PT values with practical field inputs
• Vacuum protocol timer - log evacuation sessions, track pressure drop, and save airtight or leak detected results automatically
• Project CRM - store client details, addresses, photos, materials, refrigerant data, notes, and linked documents in one place
• Installation checklists - complete wall mounted, cassette, ducted, and multi split workflows with clear warnings for missing steps
• Estimate builder - calculate material and labor costs to create more accurate quotes and project totals
• Reference library - access fasteners, torque tables, copper pipes, refrigerants, tools, and other technical references offline
• Emergency codes - search fault codes by brand and open a clear diagnosis, cause, and fix reference fast
• Achievements - track your progress with professional milestones such as First Installation, Vacuum Master, and HVAC Legend
• PDF and document support - generate organized records for customers, project history, and internal use

PERFECT FOR

• HVAC installers who need reliable field tools without depending on internet access
• Service engineers and small climate-control companies that want cleaner documentation and faster workflows

WHY CHOOSE US This is not a generic note app or a basic calculator. It is a complete engineering-grade workspace designed around real installation and service workflows. From onboarding to project tracking, from evacuation logs to troubleshooting, every screen helps you work with more confidence, fewer mistakes, and better records.

Built for offline use first, with local storage as the source of truth and optional synchronization for backups, support, and exports when enabled.
