Picked

Hightower Service, Inc.

carrier.com
“Hightower has been family-owned in Arlington (606 W Main St) since 1952, is a Carrier Factory Authorized Dealer that won a Carrier President's Award within the past three years, employs NATE-certified technicians, shows Texas license TACLA003102C on its homepage, has 445 reviews rated Excellent through its Google-sourced Trustindex widget and 4.9/5 on 36 Carrier.com reviews, offers 0% for 18 months or 9.99% for 120 months financing on qualifying Carrier systems, and includes a free one-year maintenance agreement with a new system, although it does not publish how long its labor warranty lasts.”
Shortlisted #2

Cool Tech Mechanical

cooltechmechanical.com
“Cool Tech is based in Arlington (325 Crowley Rd), shows license TACLA44879E, is a NATE-certified Trane Comfort Specialist on Trane's dealer page, has 4.8 stars across 390 reviews on Trustindex, has been BBB accredited with an A+ since 2011, includes a two-year labor warranty on every install with paid upgrades to five or ten years, and backs its work with a $25,000 Good Contractors List guarantee.”
Shortlisted #3

Texas Air Authorities Inc

texasairinc.com
“Texas Air Authorities has been in Arlington since 1999, shows license TACLA 019762C, is a Lennox Premier Dealer and factory-trained per Lennox's dealer locator, installs Lennox, Trane and Goodman, has NATE-certified technicians, and gives 10% off installs to veterans and military, which makes it a good third bid with a different brand, though its site shows a 4.9 rating without a review count and only mentions a one-year warranty on new equipment, so ask exactly what the labor warranty covers.”
Looked at, passed

Frosty's HVAC

frostyshvac.com
“Frosty's has the most open pricing I found (flat-rate tiers from $8,000 to $20,000+), license TACLA126718E, a Manual J load calculation and a city permit included, and 4.9 stars on 143 Google reviews, but it works out of Farmers Branch about 22 miles away, has less review volume than the picks, and covers labor for only 1 to 2 years on its lower tiers unless you pay $3,500 for the 10-year add-on, so it works best as a price check.”
Looked at, passed

Arlington AC & Heating

arlington-ac.com
“Its homepage advertises a 10-year labor warranty on installs and says it was founded in 1973, but I saw no Texas license number or brand affiliation there, and the BBB profile lists the business start as 2002 and says it is not BBB accredited, so I could not confirm its credentials.”
Looked at, passed

Astar Air Conditioning, Plumbing & Electric

astardfw.com
“Astar is a Lennox Premier Dealer with 4.8 stars across 2,800+ reviews and license TACLB00028662E, but it is a multi-trade company focused on Dallas that lists Arlington as one of more than 30 service areas, and its homepage publishes no installation warranty terms.”
Looked at, passed

Texas Air & Heat, LLC

trane.com
“Trane lists it as an Arlington Trane Comfort Specialist, but I found no company website, license number, review count or warranty details to check it further.”
Looked at, passed

Cold Factor Heating & Air Services

coldfactor.com
“Its DFW pricing guide was useful for cost data, but its offices are in Roanoke and Flower Mound in north DFW, and the page I opened showed no Arlington service, license number or review data.”
Looked at, passed

HVAC Services Pro

hvacservicespro.com
“It is a multi-state company founded in 2023 whose page is aimed at Dallas, Plano, McKinney, Allen and Frisco, and its own site data shows just one review, so I used it only for cost figures (including advertised Trane systems from $6,999 installed for 3 tons).”

How we ran this

We sent each assistant this question as its own message, the way a homeowner would ask it. It searched the web and read business sites on its own. Each answer shows which assistant and version answered and when. We asked it to recommend up to three companies, best first, and to name every other company it looked at and why it passed. Reasons are quoted as given. Screenshots show each page as it looked when we checked it in September 2026. We ask again every month and keep every answer.

Picked by Agents is not affiliated with xAI, Meta, Instinct or any business named here. Recommended means the assistant recommended it. Nothing was booked.
