COMcheck Houston (Commercial HVAC)

COMcheck is one of the fastest ways for a commercial HVAC permit to get stuck. If model numbers don’t match, efficiencies aren’t supported, or the final report isn’t complete, plan check will kick it back. This page shows what to prepare (and how FlashPermit handles it end-to-end).

What plan check flags

Avoid

Mismatched model numbers

Application vs AHRI vs COMcheck inputs

Unsigned final report

COMcheck PDF missing preparer signature

Scope doesn’t match docs

“Replace AC” without tonnage/location details

The fix is alignment: scope → equipment docs → AHRI → COMcheck → submission.

What it is

What COMcheck is (and why it matters for permits)

COMcheck is an energy compliance report used on many commercial projects. For commercial HVAC scopes, it’s typically used to document that the equipment efficiencies and related inputs meet the applicable energy requirements. Requirements vary by scope and AHJ.

When it’s typically required

When COMcheck is typically required (Houston commercial HVAC)

  • • Many commercial HVAC replacements affecting energy compliance
  • • RTU and package unit changeouts (common)
  • • New commercial installs / tenant build-outs (common)
  • • Capacity changes, scope expansion, or equipment relocation (scope-dependent)

Disclaimer: This is practical guidance. Always verify requirements with the authority having jurisdiction.

COMcheck checklist

What we need to produce a clean COMcheck

Inputs that usually matter

  • • Job address + suite + jurisdiction
  • • Scope clarity (like-for-like? tonnage change? duct changes?)
  • • Equipment model numbers (exact)
  • • Efficiency data from cut sheets
  • • AHRI certificates (when applicable)

How COMcheck gets kicked back

  • • Model numbers don’t match across docs
  • • Final report missing preparer signature
  • • Scope too vague to support inputs
  • • AHRI doesn’t match what was claimed
  • • Packet doesn’t align with what’s actually being installed

The goal: one consistent story across scope letter, equipment docs, AHRI, COMcheck, and the permit application.

FAQ

Common COMcheck questions

Not always, but many commercial RTU and package unit changeouts commonly trigger COMcheck. Whether it’s required depends on scope and AHJ.
Model numbers and efficiency documentation not matching across the packet (application, AHRI/cut sheets, and COMcheck), plus missing signature on the final report.
Yes. We handle the COMcheck (when required), verify equipment documentation, and submit through iPermits as part of the permit packet workflow.
No—this is practical guidance based on common commercial HVAC permit workflows. Codes and requirements can change. Always confirm final requirements with the authority having jurisdiction.
