All Pro Plumbing, Heating, Cooling & Electrical
allproplumbers.com“Its Fontana page publishes undated ranges with no unit size: standard central AC install $5,500-$9,500, heat pump $6,500-$12,000 and single-zone ductless $3,500-$8,000; BBB lists it as accredited since 9/19/2014, and the page points to CSLB for license checks but I read no license number.”

RC Air Heating & Air Conditioning
rc-airconditioning.com“It is a family business since 1980 serving Fontana, lists license #445508 and claims a 4.9 average from 775+ Google reviews (its own claim), and BBB shows an A+ rating but not accredited; its page has no install prices, but a California contractor's 2026 blog (Alex Air Heating) puts central AC installed at about $5,000-$12,000.”
Passed
JC Energy Solutions
jcenergysolutions.com“Its page posts an undated price list (3-ton 14 SEER2 $5,500-$7,500, 4-ton 16-18 SEER2 $9,500-$13,500, overall $5,500-$16,000) and shows CSLB #998538, but CSLB listed that license as suspended for contractor-bond reasons when I checked it in an earlier study, and it is Hesperia-based.”

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 October 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.
