## Frequently asked questions

### Can this workflow replace a stamped HVAC design?

No. It supports estimation, troubleshooting, and engineering review, but it does not replace qualified design responsibility, site verification, code checks, manufacturer selection, or safety approval.

### When should I include psychrometric calculations?

Include them whenever humidity control, latent load, coil performance, condensation risk, or outside-air treatment affects the review conclusion.

### Why use both COP and EER or SEER checks?

COP helps compare thermodynamic performance directly, while EER and SEER help relate the review to HVAC equipment ratings and seasonal expectations.

### What makes the comfort conclusion credible?

State the assumed dry-bulb temperature, humidity, air speed, clothing, metabolic level, and occupancy context, then tie the PMV result back to those assumptions.
