Picked
“It's the only Dallas-based company I found that publishes a full installed tankless price, starting at $4,999 with the unit (or $2,299 if you supply the heater), including sizing, removal of the old heater, and an 8 to 12 year warranty on most installs, with code upgrades quoted up front.”
Shortlisted #2
“This Irving company that serves Dallas publishes fixed installed prices of $2,800 and $4,100 for a Navien, A.O. Smith, or Rinnai gas tankless unit, done the same day by a licensed plumber, though it doesn't say what separates the two prices or whether gas line and venting work are included.”
Shortlisted #3
“It's a local Dallas company that says it's a certified Rinnai, Navien, and Rheem tankless installer and handles the gas line and venting upgrades itself, with 37 years in business and its own installation guarantee, but you'd need to get a quote because it publishes no price.”
Looked at, passed
“It's a strong Dallas company in business since 1957 with 4.8 stars on more than 1,160 Google reviews, but it shows no tankless price and no manufacturer certification.”
Looked at, passed
“Its 'starting at $2,500' tankless line lumps installation and repair together without a breakdown, and it's based in Royse City rather than Dallas.”
Looked at, passed
“It shows only a generic $1,200 to $5,000-plus range and looks like a lead-referral network with no local address.”
Looked at, passed
“Its $6,000 to $12,000 range for full Dallas installs is useful for budgeting but isn't a price you can book, and the company is based in Fort Worth.”
Looked at, passed
“Its tankless page is generic, with no price, certification, or warranty details.”
Looked at, passed
“Its $1,000 to $3,500 figure is a national-average guide rather than its own price, and its offices are northwest of Dallas.”
Looked at, passed
“It's a referral network with no local address, and its Dallas price is an estimate based on national averages.”
Looked at, passed
“It's a tankless specialist with a detailed $2,900 to $5,800 conversion range, but its page covers only Frisco and never mentions Dallas.”

Picked
“The only Dallas company found that publishes an actual installed price - tankless installation starting at $4,999 (or $45/mo) and $2,299 if you supply the unit - with upfront pricing, a free online quote and a one-hour arrival window.”
Shortlisted #2
“It publishes the most detailed Dallas-specific tankless cost guide: $6,000-$12,000 all-in including gas line upsizing ($750-$2,000+), venting ($750-$2,300) and electrical work, with a neighborhood-by-neighborhood price table.”
Shortlisted #3
“Its Dallas cost guide publishes concrete tankless ranges - gas tankless $3,000-$6,500+ and electric tankless $2,500-$5,000 - broken down by unit type, venting and code upgrades.”
Looked at, passed
“It publishes an excellent all-in tankless price table ($3,200-$5,500 installed plus $400-$1,500 gas line upsize) and is a certified Rinnai/Navien installer, but the page and service focus are Plano rather than Dallas.”
Looked at, passed
“It shows a $1,200-$5,000+ tankless range with free estimates, but the page is a generic template (the same range appears across its city/service pages) so the numbers are less trustworthy.”
Looked at, passed
“Established DFW plumber with a Dallas water heater page covering tankless, but no published prices or online booking on the page.”
Looked at, passed
“Its Dallas tankless page quotes $2,375-$5,225, but it is a lead-matching site that routes you to an unnamed plumber rather than an actual plumbing company.”
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.
