For commercial HVAC and refrigeration shops, 5–20 techs
EPA 608 Logs Your Techs Will Actually Fill Out.
We're building it to work on your techs' phones — even on a roof with no signal — shaped by 47 shop-owner conversations. Pilot opens August 2026.
No payment now — you're locking in the $1,499 founding price for the Aug 2026 pilot.
Founding pricing is limited to the first 100 shops.
We won't share your email or market to your techs.
The Problem
Paper Logs Are a Compliance Liability
Every HVAC contractor we spoke to runs compliance on paper. All of them are one EPA audit away from serious consequences.
Manual Leak Rate Calculation Errors
EPA 608 leak rate math is unforgiving. One transposed number or wrong formula on a paper log puts you out of compliance — even when your technician performed the job correctly.
Paper Logs That Don't Survive Audits
Inspectors reject smudged, incomplete, or missing records. One lost log book can expose your entire service history — and there's no recovering it once an EPA inspector is at your door.
$59k/Day EPA Penalties
The EPA doesn't negotiate on paperwork violations. Potential penalties can exceed $59,000 per day, per violation. For a 10-person shop, a single audit failure can be a business-ending event.
From a phone on the roof to an audit-ready report
This is the workflow we're designing with 47 shops: your tech logs refrigerant in the field — even offline — and you export an audit-ready EPA report in one tap.

A note from the founder
I spent six months researching about HVAC refrigeration compliance before writing a line of code — 47 owner interviews, because the worst thing I could do is build another tool contractors ignore.
I found EPA 608 after reading that refrigerant leaks cost Kroger $2.5 million in fines in 2026. Then I looked closer and saw every commercial shop running compliance on paper or scattered spreadsheets — no leak-rate math, no threshold alerts, no fast way to produce an audit report.
RefGuard is what comes next.

From Job Site to Audit-Ready
Three steps. No tech training. We're designing for first compliant log in under 4 minutes — tell us if that's realistic for your crew.
Log Refrigerant on Mobile
Technicians will capture cylinder readings, job site details, and refrigerant type from their phone — even offline. Data syncs automatically when they're back in range.
Auto-Calculate Leak Rate
RefGuard will run the EPA 608 formula for every appliance automatically, flagging anything that crosses a regulatory threshold before it becomes a violation.
Generate One-Click EPA Report
When an inspector calls, you'll export a complete, formatted compliance report in seconds. Every log entry, signature, and calculation included and timestamped.
