Hamstra Heating & Cooling's page as the assistant saw it
Picked

Hamstra Heating & Cooling

hamstrahvac.com
“It has been family-owned in Tucson since 1983, shows residential license ROC 059073 and commercial license ROC 069869 on its site, advertises 24/7 emergency service, posts recent reviews from 85718 and 85750 customers, and has a 4.9 rating across 3,595 reviews on Birdeye, the largest verified review count of any company I looked at.”
Shortlisted · 2nd choice

Samson and Sons Heating & Cooling

https://www.bbb.org/us/az/tucson/profile/residential-air-conditioning-contractors/samson-and-sons-heating-cooling-1286-20087113
“It is a BBB-accredited, A+ rated family business in Tucson since 2015 with ROC 299173 active until 7/31/2027, it lists repair as a specialty, and it appears to be the company r/Tucson recommends most, though it is on the west side (85745) and only takes Sunday emergencies rather than offering full 24/7 service.”
Rincon Air Conditioning & Heating Co.'s page as the assistant saw it
Shortlisted · 3rd choice

Rincon Air Conditioning & Heating Co.

rinconac.com
“Its site says it is in its 65th year of business, its east-side Speedway office is close to the Foothills, and Reddit users describe it as trying the cheap fix before pushing a replacement, though it has only about 105 to 109 reviews, keeps weekday-only office hours, and the only license I found (067997) is listed as C-39 commercial, so its residential license needs confirming.”
Passed

Intelligent Design Air Conditioning, Plumbing, Solar & Electric

idesignac.com
“It has an 85718-specific page, four ROC numbers, and 24/7 service, but the same page claims both 3,600+ and 23,000+ reviews, it runs many trades beyond HVAC, several Reddit posts praising it read like planted ads, and search results mention recent BBB complaints.”
Passed

Perry Heating, Cooling & Plumbing

perryheatingandcooling.com
“It dates to 1949, offers 24/7 service with tiered pricing, and has good Reddit repair stories, but its site shows no ROC number and the only licenses I found (339807 and 339808) list an 'Alameda' address and an 8/31/2026 expiration, so I could not confirm it is currently licensed.”
ACS Air & Plumbing's page as the assistant saw it
Passed

ACS Air & Plumbing

acshvac.com
“Its Foothills page is strong (since 1990, 24/7, written upfront repair pricing of $200 to $1,800, lifetime workmanship guarantee), but it shows no ROC number and I found no review volume or BBB data to check it against.”
Passed

Semper Fi Heating & Cooling

semperfiheatingcooling.com
“Search results show a Mesa-based BBB profile with high-pressure sales and billing complaints, and its Reddit praise is repetitive enough to look planted.”
Passed

Viking Cooling & Heating

vikingair.net
“It has a Foothills page, free second opinions, and senior and veteran discounts, but I saw no ROC number, rating, or review count, and it is based in northwest Tucson (85743).”
Passed

Rite Way Heating, Cooling & Plumbing

ritewayac.com
“It claims service since the 1950s and 24/7 availability, but I found no ROC number, rating, or review data, and it is a multi-trade company based in south Tucson (85714).”
Passed

Complete Comfort Heating & Cooling

comfortarizona.com
“It is a small service-area business with a Gmail contact address that claims a 5-star Google rating and a BBB A rating without showing a license number or review count.”

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.
