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. 5 HVAC contractors on the Arlington service roster hold licenses we checked in October 2026; 5 are ranked here. One fact stated up front: no Arlington 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 Arlington 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 Arlington HVAC contractor ranking that prints the license number and check date behind every name.

Registry profile
How this ranking works
Most “best HVAC contractors in Arlington” 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. A 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 Arlington; (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.
Arlington, in numbers
- Population: an estimated 402,134 on July 1, 2025, up 2.0% from 394,266 at the April 1, 2020 Census (U.S. Census Bureau QuickFacts V2025). Median value of owner-occupied housing units, 2020-2024: $304,700; owner-occupied rate 54.3% (Census QuickFacts, 2020-2024).
- Schools: five districts serve Arlington addresses — there is no single Arlington district. Arlington ISD serves most of the city and earned a C (76 as released; a post-appeal score of 77 exists after a granted rescore appeal) in TEA’s 2025 accountability ratings; Mansfield ISD earned a B, and Kennedale ISD, Grand Prairie ISD and Fort Worth ISD (73) each earned a C (Texas Education Agency 2025 ratings). Verify the district for a specific address with the district or on TEA’s TXschools.gov before relying on any school claim for that address.
- Taxes, Tax Year 2026: a city-limits parcel in Arlington ISD stacks City of Arlington $0.629800 + Arlington ISD $1.096100 + Tarrant County $0.186000 + Tarrant County College $0.120000 + JPS Health Network (hospital district) $0.159000 = $2.190900 per $100 of taxable value, before any special district (Tarrant County Tax Office Truth-in-Taxation summary, Tax Year 2026). The same stack totals $2.241700 in Mansfield ISD, $2.230000 in Kennedale ISD and $2.123899 in Fort Worth ISD; no total is stated for Grand Prairie ISD parcels because that district’s Tax Year 2026 rate does not appear in the county table. Confirm the entities and rates for a specific parcel with the Tarrant Appraisal District.
- On this Registry: 5 HVAC contractors serving Arlington hold licenses read at the authority in October 2026; the HVAC contractor seat is unclaimed.
