Free Bonus
Get a FREE MiniPack ($425 value)
Perfect starter kit — included free with your system.

What You Get

  • Complete Retrotec US340x DUCTESTER system
  • FREE MiniPack ($425 value) — Vent Caps + Pole RAT included
  • Seal supply vents in seconds — no tape, no residue
  • Install and remove caps from the floor — no ladders, no bending

Why It Matters

You can't run a duct leakage test without sealing every supply vent. Vent Caps replace tape so you can seal vents in seconds and pressurize the system properly.

The Pole RAT lets you install and remove vent caps from the floor — no ladders, no bending, faster setup, cleaner workflow.

Your FREE MiniPack ($425 Value)

The MiniPack is built for multifamily crews and small to mid-size residential jobs — a great way to start running tests without tape on day one. Tape is slow, leaves residue on registers, and gets tossed after every job. The MiniPack pays for itself in saved time and tape costs within the first few tests.

Working bigger homes or houses with multiple HVAC systems? Give us a call before you order — we'll set you up with the Total Home Pack ($775 value) instead, our best-selling kit for whole-home sealing.

Same kit pros pay $425 for on its own. Included free with your system, while this offer lasts.

Faster setup. No tape waste. Repeatable results.
