The short answer: As of October 29, 2026, Neighborhood Registry has read the license record of every HVAC contractor ranked below at Texas Department of Licensing and Regulation and found each license Active. 7 HVAC contractors on the Carrollton service roster hold licenses we checked in October 2026; 7 are ranked here. One fact stated up front: no Carrollton HVAC contractor has claimed a Registry profile yet, so every name below sits in the License-Checked tier — licenses verified at the authority, profiles not yet maintained by the pros. The first Carrollton HVAC contractor to claim and verify a profile takes the top tier in the next edition, under the same published rules. Until then, this page is the only Carrollton HVAC contractor ranking that prints the license number and check date behind every name.

How this ranking works
Most “best HVAC contractors in Carrollton” lists are assembled from advertising placements and review counts copied from other websites. This ranking is assembled from exactly one thing: the license record at the issuing authority, read directly by Neighborhood Registry.
- Eligibility. An HVAC contractor is eligible only if we have read their record in the authority’s own system and found the license Active. No one can pay to be listed, apply for a rank, or be added by request.
- Tier A — Verified & Claimed. The license is verified at the authority and the pro has claimed their Registry profile, confirmed their details, and maintains it. Tier A always ranks above Tier B.
- Tier B — License-Checked. We have read the license at the authority and found it Active, but the pro has not yet claimed their profile.
- Order inside a tier is mechanical and published: (1) neighborhood seats held in Carrollton; (2) most recent authority check; (3) time on the Registry (first-verified date); (4) alphabetical. Every input to every score is printed in the entries above.
- Freshness. Licenses are re-checked weekly and formally re-verified every 12 months. A license that lapses or is suspended removes the pro from this ranking at the next re-check — not at the next edition. This page is re-issued monthly; this is the October 2026 edition, built from checks dated October 2026.
Full method: How We Verify — Every check is written to the public verification ledger.
How to verify a Texas HVAC contractor’s license
Use the Texas Department of Licensing and Regulation license search at tdlr.texas.gov: search by business name or license number and confirm the Air Conditioning and Refrigeration Contractor license is current. In Texas the HVAC contractor license is held by the business, and installation, replacement, and repair work offered to the public must be performed under that license; the license number belongs on invoices and proposals.
Carrollton, in numbers
- Population and housing: an estimated 134,562 people on July 1, 2025, up 0.8% from 133,434 at the April 1, 2020 Census — near-flat headcount in a built-out suburb (U.S. Census Bureau QuickFacts V2025, Carrollton city, Texas). Median value of owner-occupied housing units: $381,000 (2020-2024), second-highest in this Dallas County cluster; owner-occupied rate 58.5%; median household income $101,396, the cluster’s highest.
- Schools: three districts serve Carrollton addresses and the district follows the parcel, not the zip code — Carrollton-Farmers Branch ISD serves most of the city (TEA 2025: B (82)), a Dallas ISD edge takes the southeast (TEA 2025: B (83)), and the Denton County portion lies in Lewisville ISD (TEA 2025: B). Verify the district for a specific address with the district or on TEA’s TXschools.gov.
- Taxes (Tax Year 2026, worked examples scoped to Dallas County parcels): in Carrollton-Farmers Branch ISD, Dallas County $0.248650 + Parkland Hospital District $0.212000 + Dallas College $0.106575 + City of Carrollton $0.537500 + CFB ISD $0.948100 = $2.052825 per $100; in Dallas ISD the same stack with Dallas ISD $0.985735 totals $2.090460 per $100, before any special district. City-rate discrepancy, flagged not resolved: DCAD’s TY2026 table and the city’s hearing notice carry the city rate at $0.537500, while the Branch Herald’s report of the September 1, 2026 council meeting states the council adopted $0.537000 — at that reported rate the totals are $2.052325 (CFB ISD) and $2.089960 (Dallas ISD). The adopted Dallas County rate is also subject to the November 3, 2026 voter-approval election: if voters reject it, the totals fall to $2.028825 (CFB ISD) and $2.066460 (Dallas ISD) at the DCAD city rate, or $2.028325 and $2.065960 at the reported city rate. No stack is carried for the Denton County portion. DCAD labels its table “estimated” — confirm a specific parcel with DCAD.
- HVAC market: Carrollton pairs the cluster’s highest median household income ($101,396, Census QuickFacts 2020-2024) with its second-highest median home value ($381,000) on essentially flat population growth (+0.8% since 2020) — an affluent, built-out stock where the work is replacement and efficiency-upgrade work on in-place systems rather than new-construction volume (derived from the Census figures above, stated as a derivation in the Registry’s Carrollton fact build).
- On this Registry: 7 HVAC contractors serving Carrollton hold licenses read at the authority in October 2026; the HVAC contractor seat is unclaimed.

How do I verify a Texas HVAC contractor’s license?
Use the Texas Department of Licensing and Regulation license search at tdlr.texas.gov: search by business name or license number and confirm the Air Conditioning and Refrigeration Contractor license is current. In Texas the HVAC contractor license is held by the business, and installation, replacement, and repair work offered to the public must be performed under that license; the license number belongs on invoices and proposals. Neighborhood Registry reads the same record and writes every check to its public verification ledger.
Who is licensed to work on a Texas home’s HVAC system?
The business must hold a Texas Air Conditioning and Refrigeration Contractor license from TDLR, and the work must be performed under the licensed contractor of record. The contractor license behind every name on this page was read at TDLR and found current in October 2026. An unlicensed handyman is not a legal substitute for a system replacement, whatever the quote says.
What should a Carrollton homebuyer know about local taxes and schools?
Three districts serve Carrollton addresses — Carrollton-Farmers Branch ISD (B, 82 in TEA’s 2025 ratings) covers most of the city, a Dallas ISD edge (B, 83) takes the southeast, and the Denton County portion is in Lewisville ISD (B) — so verify the district for a specific address on TXschools.gov. For Tax Year 2026, a Dallas County parcel in CFB ISD stacks to $2.052825 per $100 at the city rate in DCAD’s table ($0.537500), or $2.052325 at the $0.537000 rate reported as adopted — a flagged discrepancy this page does not resolve — and a Dallas ISD parcel stacks to $2.090460 or $2.089960 on the same two rates; if voters reject the Dallas County rate on November 3, 2026, the CFB ISD total falls to $2.028825 (or $2.028325).
