ABOUT
BTU Consulting Group was founded by Shai Zohar, an independent HVAC consulting engineer based in Philadelphia, after nearly six years designing mechanical systems at an MEP engineering firm.
Our work spans pharmaceutical, mixed-use, and residential projects, with a focus on bringing that same rigor to single-family and high-end custom homes, where HVAC is too often an afterthought.

FAQs
Common Questions
Do you work directly with homeowners?
Yes. BTU Consulting Group can support homeowners directly, as well as builders, architects, and interior designers involved in the project.
Do you only do residential work?
Our core focus is residential HVAC design for single-family and custom homes. For commercial projects, signed and sealed design services are available through collaboration with a partnered engineering firm.
Can you help coordinate hidden or more modern diffuser options?
Yes. That type of coordination is exactly the kind of thing that should be discussed early so the HVAC system supports the architectural intent rather than fighting it.
What makes your service different?
The value is not only in the calculations and drawings — it is also in how the system is integrated into the project so it performs well, looks intentional, and supports the final design.
