Report a part problem
Tell us about a part that broke, didn’t fit or could work better. Every report goes to the design team and shapes the next version of the part.
- Say what you were doing when the problem happened.
- Include how long the part had been in use, if you know.
- A photo of the damage or the fit helps the most.
Report sent
Thanks for telling us. We read every report, and we’ll email you if we need more detail.
Back to all partsParts made for the people who balance the air
We design and 3D-print fixtures, adapters and fittings for HVAC test-and-balance work. Browse the current prototypes and ask about any part for your crew.
Prototype schedule
Each part started as a problem on a real balancing job. Select a part to see how it’s used and photos of the prototype.
From jobsite problem to printed part
Tell us the problem
A fitting that doesn’t exist, a hood that won’t seal, a probe that won’t stay put.
We model it
We design the part in CAD around your measurements and equipment.
Print and field test
Prototypes go out with technicians and come back with notes.
Refine and supply
Proven designs are finalized and made available to order.
