Steps to perform on site to gather existing HVAC system information:

#1 Ask if there are existing plans of the HVAC systems.

These sometimes can be found on site.

1 blueprints

#2 Take some photos of the existing building for load calculations.

  • Photos are best if taken further back for overview of building type.
  • Photos of glass and overhangs are good.
  • Interior photos that show wall heights and glass.
  • Interior photos of RCP that show diffusers in grid (especially when ceiling to remain).

This project was completed in about half the time expected. Proficient’s ability to meet deadlines, fast responses and plan accuracy were key. The MEP work was on point. Ron knew when to challenge things and when to be flexible. I never had to think twice about whether Ron could respond or implement. They were always on time. It was seamless and easy to work with Proficient.
