Contractors *really* like Amply
The HVAC industry has a design problem.
Many HVAC contractors still do business like in the ‘old days’ – swapping boxes, replacing like for like and moving on. In the heat pump world, the result is often oversized systems, unhappy homeowners, and poorly priced solutions that don’t deliver.
Amply customers are different – they use Amply as an opportunity to build great systems and a highly loyal customer base. These contractors care deeply about quality work – and they use Amply to design and sell accurate, high-quality solutions to homeowners who value the expert approach.
Amply is: Accurate load calcs in minutes, not hours. And a design experience that shows homeowners exactly what you're doing and why, so your expertise isn't just real, it's obvious.
One visit. 20 minutes. A system designed right.

| Amply | The Competition |
|---|---|
| Easy to learn, fast to master | Complex and difficult to use |
| LiDAR-driven measurements: fast and accurate | Either fast OR accurate – not both |
| Proudly independent owner-operators | Owned by private equity or giant corporations |
| Transparent pricing built for independent contractors | Pricing that's high, hidden, or structured for PE-owned rollups |
| Works fully offline | Requires a strong internet connection |
Many contractors do quality work but find themselves caught between Private Equity–backed companies built to scale quickly at the expense of quality, and “Stan in a Van” businesses whose lack of process keeps them confined to a one-person shop.
We’ve spent hundreds of hours talking with contractors who’ve broken out of that trap. The Heat Pump Podcast is where they share how they did it, including how they communicate value, earn trust, and build businesses that don’t race to the bottom. We love sharing what we learn from the best.

Powered by ACCA Manual J®
Whether or not your state or municipality requires an ACCA Manual J load calculation, it is the gold standard for high-performance contractors. Amply’s unique approach to load calculations has been certified by ACCA, who sets the standard for load calculations and good system design.
Why Amply Exists
Too much of the industry has optimized for speed and sales at the expense of craft and trust. Having designed and sold heat pump systems ourselves, we created Amply to support contractors who want to do the work right and still build strong, independent businesses. We believe better design, clear process, and earned trust are how homeowners live in comfortable, healthy, efficient homes. And it’s how contractors build businesses they love to run.
