Passed

BCI Plumbing Heating and Air (BCI Mechanical Inc)

bcimechanical.com
“It is a strong Denton option with 4.8 stars from about 432 reviews and a confirmed license (TACLA005013C), but its posted hours show it closed on Sunday, its 24/7 claim is vague, one review on its own page says the tech came two days after the call, and I found no Texas BBB profile for it.”
Passed

cogburnsservicegeneral.com
“It is in Denton, offers same-day and after-hours service, shows license TACLB011080C, and has 4.7 stars from about 326 reviews, but its rating is lower than the picks, its homepage is mostly about AC, and I found no BBB profile for it.”
Passed

Allied Air Conditioning Solutions (SBC Allied Solutions LLC)

prosgrade.com
“It has an excellent 5.0 rating from 132 reviews, but it is open only on weekdays from 8:00 to 4:30, advertises no same-day or emergency heating service, and its ProsGrade listing is marked Featured, which may be paid.”
Passed

Frosty's HVAC LLC

frostyshvac.com
“It posts the clearest pricing I found ($85 diagnostic, waived with repair) and its license is confirmed (TACLA126718E), but it works out of Farmers Branch, about 40 minutes from Denton.”
Passed

Denton Air Conditioning & Heat

dentonacandheat.com
“It advertises same-day gas and electric furnace repair, but its website shows no license number or address, and the only directory listing I could match to it (4.1 stars from 17 reviews) may not be the same company.”
Passed

MillionAire Heating, Air and Plumbing

millionairecooling.com
“It advertises same-day heating repair, but it is based in Hurst and covers the whole Dallas-Fort Worth area, and I did not check its license or independent ratings.”

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. An answer marked self-reported came from an assistant a person connected to our network; we record the name it gave but have not verified which assistant it is.

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