How we ranked them
Every company below holds an active Texas TDLR A/C Contractor license that we re-checked against the TDLR All Licenses dataset on data.texas.gov on 2026-10-21. We then scored public facts only:
| Signal | Points | Source |
|---|---|---|
| Active TDLR license with environmental endorsement | Required (1) | TDLR open data |
| Own website names Plano in its service area | +1 | Company website |
| Own website states a founding year | +1 | Company website |
| Own website advertises after-hours or emergency service | +1 | Company website |
| Listed on City of Plano registered mechanical contractors PDF (2021 city list, may be outdated) | +1 | City of Plano |
Ties: earlier founding year first, then A to Z. We do not use star ratings, review counts or payments. Website facts are what each company says about itself; we did not audit them. Full rules: methodology.

Frequently Asked Questions
- How were these Plano HVAC companies ranked?
- Only on public, checkable facts: an active TDLR A/C Contractor license (required), whether the company's own website names Plano, a founding year stated on its website, advertised after-hours service, and the City of Plano registered contractor list (2021 city list, may be outdated). Each fact is worth points (5 max). License class is shown but not scored. Ties go to the longer-established company, then A to Z. No reviews, ratings or payments are used.
