Two homeowners in the same neighborhood search on the same Tuesday. One woke up to cold water and a tank that clicks and does nothing. The other has a fourteen-year-old water heater with a rust stain at the base and a spouse who wants it gone before it floods the garage. Both type "water heater" into Google. One needs a technician tonight. The other is about to spend a few thousand dollars and wants to know exactly on what.
A plumbing account that sends both of them to the same campaign, with the same budget and the same ad, is asking one ad to make two different promises. This chapter splits them.
Water Heaters Lead Plumbing Reviews. The People Searching Want Three Different Jobs.
No service line came up more in our research. In our example market, San Antonio, 79 of 794 Google reviews of plumbing companies mention a water heater, the most of any service line we counted. Among 210 low-star reviews of plumbing jobs, 32 are water heater jobs, 28 of them tank units and 4 tankless. On Reddit, 14 of the 54 homeowner threads we read were about a water heater.
The searches split the same job three ways. Keyword Planner's US monthly figures:
- Repair: "water heater repair near me" 90,500, "water heater repair" 74,000.
- Replacement: "water heater replacement" 49,500, "water heater installation near me" 27,100.
- Tankless: "tankless water heater repair" 18,100, "tankless water heater installation near me" 3,600.
Those are three different people. The repair searcher has a problem today and wants to know how fast you can come and what it costs to look. The replacement shopper has a decision to make and wants a model, a price and a date. The tankless shopper is often deciding whether to switch at all, and the price gap between quotes is where they get burned.
12 of 34 Water Heater Ads Sold Repair and Replacement in One Breath
We read every water heater ad in our example-market sample of Google's Ads Transparency Center: 34 ads from 17 advertisers. Here's how they pitched the job:
- 12 promised repair and replacement in the same ad.
- 9 were about repair only.
- 9 were about replacement or installation only.
- 15 promised same-day service. 5 mentioned tankless.
An ad that says "water heater repair and installation" is talking to both homeowners at once and answering neither one's question. The repair searcher doesn't care about installation. The replacement shopper doesn't trust a same-day fix when they're about to spend a few thousand dollars.
The reviews show what the replacement shopper is afraid of. One customer called about a leaking water heater and was offered three plans: "$2500 for standard plan $3300 for gold and $4k odd for top plan to replace the heater." Then the follow-up question: "i asked him what model are you going to install so I could check the price online he didnt know what model he would install." Another was "quoted $8600 for a tankless hot water heater," asked for an itemized receipt, and was told the company doesn't provide one.
Our example market adds a local wrinkle. Attic water heaters come up in the San Antonio threads on Reddit, and homeowners there know an attic changes the price: "attic is a whole other level of difficulty," one wrote, defending a quote that looked high.
That's three water heater campaigns, and each needs an ad and a page written for its searcher:
- Water heater repair. Same-day service if you keep it, the diagnostic or service fee from Chapter 14, and the hours someone can actually dispatch. The page answers "how fast" and "what does it cost to look."
- Water heater replacement. The model or the models you install, the installed price or a price range in writing, and what's included: haul-away, permits, the code work. In a market like San Antonio, say whether you do attic installs and what they add.
- Tankless. Its own page, a written quote, and what the install takes beyond the unit, such as a bigger gas line or new venting.
A Water Heater Repair Click Tops $126. A Replacement Job Can Pay $3,100.
Here's the number that makes the split worth doing. In the example market, Keyword Planner put the top-of-page high bid for "water heater repair near me" at $126.62. For "water heater replacement" it was $75.44. For "tankless water heater installation near me," $96.59.
Now the other side. HomeGuide, a cost guide run by a lead marketplace, puts a tank water heater repair at $150 to $700, a tank replacement installed at $600 to $3,100, and a tankless water heater installed at $1,400 to $5,600. Those ranges are wide, and your own invoices will beat them, but the shape is clear: the search that costs the most per click leads to the smallest job.
Put all three in one campaign with one budget, and the repair clicks, which are the most expensive and the most frequent, spend the money first. The replacement campaign, the one with the job worth thousands, gets what's left. Split them and each campaign gets a budget sized to what its jobs are worth, and its own cost-per-booked-job ceiling, worked out the way Chapter 3 did it: what a booked job in that line actually pays you, not what a click costs.
One vendor's numbers point the same way. SearchLight, a company that tracks calls and revenue for home service contractors, puts water heater Search leads at $256 each in its early 2026 data, against $161 for general plumbing. Treat that as one vendor's sample. The point holds anyway: a water heater replacement lead is expensive, so it needs a campaign whose budget is set by the replacement job, not by the repair calls next to it.
The Federal Water Heater Tax Credit Is Gone. An Ad Promising 30% Back Is Wrong.
Water heater ads carry more claim risk than most plumbing ads, because the rules around them changed recently and plenty of web pages haven't caught up.
The tax credit ended. The federal credit that used to pay part of a heat pump or efficient gas water heater is over. The IRS puts it in one line: "You can claim the credit for improvements made through December 31, 2025." A water heater installed today doesn't qualify. Some government pages still describe the credit as available, including a Department of Energy home upgrades page we read in October. The IRS is the agency that decides who gets the credit, so go by the IRS. An ad or a landing page that still says "get 30% back with the federal tax credit" is promising money the customer won't get.
State rebates are real but narrow. Some states run income-qualified rebates for heat pump water heaters. They open and close: California's statewide program for single-family homes was fully reserved by February 2026. If you mention a rebate, name the program and say "if eligible."
The 2029 standard binds manufacturers, not you. A Department of Energy rule raises the efficiency floor for most 20- to 55-gallon electric tank water heaters made on or after May 6, 2029, to a level DOE says is currently met only by heat pump models. It applies to units manufactured after that date. Water heaters built before it can still be sold and installed, and small electric tanks keep their own class. An ad that says "electric water heaters are being banned, replace yours now" overstates the rule.
Say whose warranty it is. "12-year warranty" on a water heater ad usually means the manufacturer's tank warranty, and the Federal Trade Commission's guides on advertising warranties apply to it. Say whose warranty it is, how long it runs and where the terms are. Your labor warranty is a separate promise. State it separately, with its own length.
Put the model in writing. The review above is the cheapest fix in this chapter. A replacement quote that names the model lets the homeowner check it, and a homeowner who can check it is less likely to assume the worst.
Co-op Money Can Cover Half a Water Heater Click, if Your Site Shows the Brand
Water heater manufacturers sometimes help pay for the ads that sell their units. Rheem's 2025 co-op advertising guide for water heating, written for distributors and the plumbers who buy from them, lists paid search "such as Google Ads (Pay Per Click)" as qualified advertising. For ads a plumber runs, the split it shows is 25% from Rheem, 25% from the distributor and 50% from the plumber.
The rules attached to that money matter more than the percentage:
- The website has to show the brand. The guide asks for "a highly visible Rheem presence," meaning images of Rheem water heaters and the Rheem logo.
- Other brands shrink the contribution. In the guide's example, an ad showing Rheem and two other brands gets a third of the standard contribution.
- The claim needs your keywords. A list of the keywords used and a link to your site go in with the claim.
That fits the replacement campaign well and the repair campaign badly. A replacement page built around one brand you install can qualify. A repair page that says you service every brand, which it should, may not. We didn't find a 2026 version of Rheem's guide, and the other three big water heater brands we checked don't publish their co-op rules for Google Ads. Ask your distributor what's current before you build a page around it.
Our Google Ads management team builds plumbing accounts with water heater repair, replacement and tankless running as separate campaigns on separate budgets.
