HVAC CFO FIRMS, SCORED ON PUBLIC EVIDENCE.
How this was made: on October 31, 2026, Claude (Anthropic's AI model, Opus 5.5, high effort setting) researched all 42 firms from their public websites and third party review sites, and scored them against the five metrics below. The metrics and weights were fixed before the research started. Every firm's scores link to the pages they came from. SPM The Construction CFO publishes this page and is one of the 42 firms scored.
- C1 construction and segment fit, 20%
- C2 evidence of client results, 30%
- C3 third party trust, 20%
- C4 capability, 15%
- C5 transparency, 15%
Why this exists: subcontractors ask us who else they should talk to. This study answers that from evidence. Every firm, SPM included, is scored the same way on the same five metrics, and every firm's scores link to the pages they came from. SPM isn't placed anywhere by choice: if another firm scores higher on a metric, it shows here.
How often it's updated: every 2 months (next on December 28, 2026). Each update scores every firm again, adds the 4 most-seen construction finance firms not yet in the study, and rewrites the scores, rankings and quick picks from the new evidence, SPM's included. Corrections go in the log below.
Salisbury Bookkeeping ranks first for HVAC; SPM ranks #3. Salisbury Bookkeeping scores 77.5 of 100 with an HVAC case study with numbers, and SPM scores 72.9 with an HVAC page and no HVAC case study with numbers. SPM publishes this study and is one of the 42 firms scored.

| # | Firm | Trade score | HVAC proof | Source |
|---|---|---|---|---|
| 1 | Salisbury Bookkeeping | 77.5 | trade case study with numbers | salisbury-bookkeeping.pages.dev |
| 2 | Straight Talk CPAs | 74.5 | trade case study with numbers | straighttalkcpas.com |

One judgment call moves this trade. Straight Talk CPAs' trade pages carry two line tax savings stories that give no client surname. The research agents split on whether those count as client results, and the merge rule takes the highest score backed by a cited URL, so they count. Counted only as testimonials, Straight Talk would score below SPM in every trade.
