What materials do you support?
Crafty currently have 1000 parts across
aluminum 8020, steel, wood, HVAC and PVC! Let us know if we're missing a part.

Where did the idea for this app come from?
I spent a year building an off grid farm and knew nothing about construction / plumbing / electrical work…
I saw that most people had to go the hardware store multiple times and many times they weren’t able to finish their work that day because the vendor didn’t have the part. So I thought if you can design your project beforehand, it will allow us to check for compatibility while you’re designing and then be able to send you all the parts! Much easier!

Which components are connected to HVAC systems?
HVAC components can get connected with various systems to enhance it’s functionality, like thermostats, building management systems (BMS), sensors, ventilation systems, energy management systems (EMS), remote monitoring and control, integration with renewable energy sources among others.

The idea for Crafty is to be a place where you can design your entire project ready to connect with other components so you have a clear vision of what you want to accomplish.

Do you have everything in stock?
No, not everything. We currently have about half of the parts and our goal is to little by little add more.
For the parts we don't have, we will give you a link for the provider that you can buy it from. Hopefully as the app gets more traction, we will start to carry more and more items so we can ship you everything in one set.

What are the types of HVAC Systems?
According to the needs and specifications of different buildings and applications, you may find yourself analyzing the following types: Split systems for residential or small buildings.
Packaged systems for roofs or beside buildings.
Ductless mini-split systems for retrofitting older buildings.
Heat pumps able to reverse the refrigeration cycle into heating.
Hybrid heat systems for regions with fluctuating weather conditions.
Variable refrigerant Flow (VRF) commonly used in commercial buildings.
And chilled water systems to cool through pipes buildings.

Are you going to add more parts?
Yes. This current set of parts that you see on the app is our initial set. We just finished this version in late April 2023 so we’re listening to the feedback we get and will evolve the app to be the best that it can be for all of you!

Why not just use a Profesional HVAC Software?
Certainly! If you're equipped with the necessary expertise and seek assistance with tasks like system sizing, ensuring energy efficiency, designing ductwork, complying with codes, or estimating costs, HVAC software can be incredibly useful. It's expected that these software solutions would provide accurate outputs, detailing all parts along with their precise measurements in a user-friendly format.

Yet, it's important to recognize that while these HVAC software tools are excellent for individual design work, they might not support online sharing of designs and specifications, preventing collaboration and visibility to others.
