HVAC Tech Companion
Beta spots are open

Become a beta tester.

Get the app free before it hits the App Store, help shape what gets built next, and tell us what a real tech actually needs. Setup takes about two minutes.

1. Grab your iPhone

The beta runs on iPhone (iOS 16 or newer). There's no Android or iPad version yet — it's coming after the iPhone app is solid.

2. Install TestFlight

TestFlight is Apple's free, official app for testing new apps before they hit the App Store. Install it from the App Store like any other app.

Get TestFlight on the App Store

3. Tap the invite link

Open the invite link on your iPhone. TestFlight will open and offer to install HVAC Tech Companion. Tap Accept, then Install — that's it.

Open the beta invite link

4. Updates arrive automatically

New beta builds show up in TestFlight as we improve the app. TestFlight can update automatically, or you can tap Update whenever a new version lands.

Ready right now?

If you already have TestFlight installed, one tap gets you in.

Leave your name and email so we can keep you posted on new builds, and tell us what you'd like the app to do better.

We only use your email for beta updates. No spam, no selling your info — ever.
