About ToolGrit
Practical tools. Rugged solutions. Built for results.
Why ToolGrit Exists
Trade professionals shouldn't have to dig through ad-heavy websites or create accounts just to run a quick calculation. ToolGrit was built to fix that.
Every tool on this site runs entirely in your browser. No data is sent to a server. No account is needed. No tracking scripts are watching what you do. You open the calculator, use it, and move on with your day.
What We Build
ToolGrit provides specialized calculators and tools across four main areas:
- HVAC - Heat load estimators, efficiency calculators, system analyzers, and ROI tools
- Electrical - Wire sizing, load compatibility, generator sizing, and NEC-based calculations
- Industrial - Air compressor analysis, leak detection, and energy loss estimators
- Productivity - Shift schedule generators, crew rotation visualizers, and business tools
Who It's For
ToolGrit is for anyone who works with their hands or their head - HVAC technicians, electricians, maintenance teams, plant engineers, shop owners, and homeowners who want real answers without the fluff.
Our Approach
Every calculator uses conservative, well-documented formulas. We'd rather give you a safe answer than an aggressive one. When a tool references industry standards (like NEC wire sizing), it follows the published tables and derating factors.
Tools are built with modern web technology (React, TypeScript, Tailwind CSS) and hosted as standalone applications. This means they load fast, work offline after the first visit, and never break because of a WordPress update.
