Air Comfort Service Heating, Cooling & Insulation

aircomfortservice.com
“Homepage says 'Same-day service available' and 'we answer 24/7' and lists St. Louis City in its service area; the emergency page says a technician is on call 24/7 (all its own claims) and warns specialty parts may not be available overnight. Published price: 'Emergency HVAC Service Call - $199 service diagnostic plus repairs' (a diagnostic fee, not a repair total; a $100 rate is for Preferred Partner members only). BBB (opened live profile, reviews, complaints): A+, accredited, 4.86/5 from 56 reviews (first page of 10 read, recent praise for fast response and AC help), 1 complaint in 3 years and 0 in the last 12 months (maintenance-contract visit fee, answered; the business response is not independent proof of satisfaction). License: St. Louis County's licensed mechanical contractor list includes 'Air Comfort Services', 11920 Missouri Bottom Rd., Hazelwood, matching its location, but the list is dated December 17, 2025 and gives no current status, so current license status is unverified.”

Meyer Heating & Air

meyerair.com
“Emergency page covers St. Louis, AC that will not cool, all major brands and 24-hour/365-day emergency service; priority for emergency calls and for Comfort Club members when the schedule is full; no same-day opening established. Non-member service calls $105 in business hours and $210 after hours (service-call rates, not repair totals; also on https://meyerair.com/service-agreement/). BBB (opened): A+, accredited, 0 complaints, 0 reviews. Google Maps (opened via its review link): 4.9/5 from 1,173 reviews, rating and count only; some previews readable (one praised quick AC diagnosis, one negative follow-up preview was truncated), individual review bodies did not load. County list includes 'Meyer Heating & Cooling, LLC', 11134 Lindbergh Business Ct., Unit D, matching its location, dated December 17, 2025, no current status. Phone differs by source: (833) 510-2455 on the live page, (314) 845-1929 in fetched text and BBB, (314) 455-7877 on Google; no cause established. Its live pages show canned chat text ('Our team is here to help. Text us!'), and its BBB profile has an odd service description ('clutches, differentials, and transfer mechanisms when part of integrated HVAC equipment'); neither was used as evidence.”
Passed

Martin-Jetco Heating and Air Conditioning

martinjetco.com
“Explicit same-day claim and a matching county-list row (also a footer 'License #: SMC X2024' with no linked record). BBB (opened): A+, 3.86/5 from 7 reviews, 1 complaint in 3 years and 0 in 12 months (details not published); two 1-star reviews raise pricing concerns and the more recent alleges the AC stayed inoperable after service (allegations, though it credits same-day arrival). BBB phone and site phone differ. A testimonial ends mid-sentence: 'He assessed the issue then another gentleman came t'.”
Passed

Keystone HVAC St. Louis

keystonehvacstlouis.com
“Claims 24/7 response and arrival within 45-60 minutes (its own); no independent BBB profile surfaced, and its opened Overland page claimed Missouri licensing through the Division of Professional Registration, which I could not substantiate.”
Passed

Indoor Comfort Team

indoorcomfortteam.com
“Advertises 24/7 residential AC repair, not vetted; page shows broken promo text ('save up to ,495 on a new system') and a stray '[/et_pb_section]' shortcode.”

Every month we asked

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.
