Best Water Heater Replacement Companies in 2026: 7 Options Compared

If you want a straightforward tank swap at a price you can see before anyone knocks on your door, Home Depot Home Services is the easiest starting point — flat-rate installation, a national warranty, (learn more about best whole-home humidifier installation options of 2026: brands and services compared) (learn more about best home ev charger installation companies of 2026) (learn more about best fireplace installation companies of 2026: who to hire and what it costs) (learn more about best boiler installation and repair companies of 2026: brands, costs, and how to hire) (learn more about best deck builders near me in 2026 (cost, reviews & how to choose)) (learn more about how to hire a contractor: the complete guide to finding, vetting, and paying a pro (2026)) and permit handling built in. If your old tank already failed and you need hot water back today, Roto-Rooter is the more dependable choice because it staffs licensed plumbers around the clock in most metro areas. We looked at 7 national and regional water heater installers and ranked them on installed cost, licensing and permit handling, warranty terms, appointment speed, and how consistently homeowners report being treated after the install.

Water heating is worth getting right. The U.S. Department of Energy lists water heating as the second-largest energy expense in a typical home, and a standard storage tank lasts roughly 8 to 12 years before it needs replacing.

How We Ranked These

Criteria	Weight	Why It Matters
Installed cost and quote clarity	30%	The tank is the small part of the bill. Labor, permits, code upgrades, and haul-away decide what you actually pay.
Licensing, permits, and code compliance	25%	Gas lines, venting, and expansion tanks are life-safety work. An unpermitted install can stall a future home sale.
Warranty on tank and labor	20%	Tank warranties run 6 to 12 years. Labor warranties vary far more, and that is where homeowners get surprised.
Availability and response time	15%	A leaking tank is not a next-week problem. Same-day coverage has real value.
Service consistency and complaint history	10%	Franchise and big-box networks vary by local crew, so track record matters more than the logo.

1. Home Depot Home Services — Best for predictable, flat-rate tank replacement

Best for: Homeowners replacing a working-but-aging tank who want the price settled before the truck arrives.

Typical installed cost: roughly $1,100 to $2,400 for a standard 40 to 50 gallon tank, per Angi homeowner cost data for big-box installs.
Warranty: 6 to 12 year tank warranty depending on the Rheem model, plus a labor warranty on the installation.

Home Depot sells water heater installation as a packaged job through licensed local contractors, with pricing quoted up front and permits pulled as part of the work. Most homeowners are quoted after a short phone or in-home assessment, and installation is commonly scheduled within a few days rather than the same day.

Pros

• Price is quoted before scheduling, so there is little room for a surprise at the end.
• Permits, haul-away of the old tank, and code upgrades are typically folded into the quote.
• Financing is available through the store, which helps when a replacement was not budgeted.

Cons

• Rarely a same-day option, which rules it out for an active leak.
• You get the installer Home Depot assigns, not a plumber you chose.
• Model selection is limited to the brands the store carries.

Who This Is Best For

Choose Home Depot if your tank is 9 or 10 years old and you are replacing it on your own schedule. The flat-rate structure is worth the wait. Do not choose it if water is already on your floor, or if you want a specific high-efficiency or hybrid heat pump model that the store does not stock.

2. Roto-Rooter — Best for same-day emergency replacement

Best for: A tank that has already failed, leaked, or stopped producing hot water.

Typical installed cost: roughly $1,300 to $3,000 for tank replacement, with emergency and after-hours work at the upper end.
Availability: 24/7 scheduling in most major metro areas, including weekends and holidays.

Roto-Rooter operates company-owned branches plus franchises across the U.S. and staffs licensed plumbers on call overnight. That coverage is the main reason to call them: a failed tank is a water damage problem first and a hot water problem second, and same-day replacement limits the damage.

Pros

• Genuine 24/7 coverage in most metro areas, not just an answering service.
• Plumbers are licensed and equipped to handle gas, venting, and drain work in the same visit.
• Common tank sizes are usually stocked on the truck or nearby.

Cons

• Emergency pricing runs meaningfully higher than a scheduled replacement.
• Quotes are typically given on site, so you have less ability to compare before committing.
• Experience varies between company-owned branches and franchises.

Who This Is Best For

Call Roto-Rooter when the tank has already failed and every hour costs you. If your heater is simply old and still working, book a scheduled quote elsewhere instead — you will almost certainly pay less for the same equipment.

3. Mr. Rooter Plumbing — Best for upfront flat-rate pricing from a local plumber

Best for: Homeowners who want a neighborhood plumbing shop with national accountability behind it.

Typical installed cost: roughly $1,200 to $2,800 installed for a standard tank.
Pricing model: Flat-rate quoted per job, not hourly, so overtime on a difficult install does not land on you.

Mr. Rooter is a Neighborly franchise network of independently owned local plumbing companies. Each location is licensed in its own state, quotes flat rates before work begins, and can handle tank, tankless, and gas-to-electric conversions.

Pros

• Flat-rate quotes given before work starts, with no hourly meter running.
• Local ownership means the same crew is available for follow-up problems.
• Handles tankless and conversion work that big-box programs often decline.

Cons

• Quality and pricing vary between franchise owners.
• Not every location offers overnight emergency service.
• Estimates usually require an in-home visit first.

Who This Is Best For

A good fit if you want a real plumber relationship and expect other work down the road. Skip it if you only want the cheapest possible like-for-like swap and are willing to shop three quotes to get it.

4. Benjamin Franklin Plumbing — Best for on-time guarantees and scheduling reliability

Best for: Homeowners who cannot afford to burn a workday waiting on a four-hour window.

Typical installed cost: roughly $1,300 to $3,000 installed depending on tank size and gas versus electric.
Signature policy: An on-time guarantee that credits the homeowner when the plumber arrives late.

Benjamin Franklin Plumbing is a national franchise network under Authority Brands, built around punctuality and straight pricing. Locations are independently owned and licensed locally, and most handle both tank and tankless replacement along with the venting and gas work a swap can require.

Pros

• Scheduling discipline is genuinely better than the industry norm.
• Upfront pricing presented before work begins.
• Established warranty and follow-up process through the national network.

Cons

• Priced at the higher end of the market for a straightforward tank swap.
• Coverage is thinner in rural areas.
• Franchise-level service consistency still varies.

Who This Is Best For

Worth it if your schedule is tight and a missed appointment costs you more than the price difference. If you work from home and can wait around, a local independent plumber will usually do the same job for less.

5. ARS/Rescue Rooter — Best for combined plumbing and HVAC work

Best for: Homeowners replacing a water heater at the same time as furnace or air conditioning work.

Typical installed cost: roughly $1,200 to $3,200 installed.
Coverage: Company-owned locations across roughly 20 states, with plumbing and HVAC under one roof.

ARS/Rescue Rooter runs company-owned branches rather than franchises, which makes service more consistent within its footprint. Because the same company handles heating and cooling, it is a practical choice when a water heater and furnace are aging out together and share venting.

Pros

• Company-owned model gives more consistent training and pricing than franchises.
• Can bundle water heater and HVAC replacement into one project and one financing package.
• Maintenance plans available for ongoing upkeep.

Cons

• Only operates in about 20 states.
• Bundled quotes can make it harder to see what each piece costs.
• Sales presentations tend to run long.

Who This Is Best For

Best when two or three aging systems need attention at once and shared venting is a factor. Not the right call for a simple standalone tank swap, where the bundling advantage disappears.

6. Lowe's Installation Services — Best for A.O. Smith equipment and store financing

Best for: Homeowners who want a specific A.O. Smith model with big-box backing.

Typical installed cost: roughly $1,100 to $2,400 for a standard tank replacement.
Warranty: 6 to 12 year A.O. Smith tank warranty by model, plus a labor warranty on the install.

Lowe's arranges installation through licensed local contractors, similar to Home Depot, with quotes provided before scheduling and permits handled as part of the job. The practical difference between the two is equipment brand and whichever store's local installer network is stronger in your area.

Pros

• Quoted pricing before scheduling, with permits and haul-away included.
• A.O. Smith lineup includes well-reviewed high-efficiency and hybrid models.
• Store financing and periodic promotions on installed jobs.

Cons

• Lead times of several days to a week are common.
• No same-day emergency coverage.
• Installer quality depends entirely on the local subcontractor.

Who This Is Best For

Reach for Lowe's if you have already decided on an A.O. Smith unit or want a heat pump water heater installed under a national program. Look elsewhere if timing is urgent.

7. A Local Licensed Plumber — Best for lowest cost and full model choice

Best for: Homeowners willing to collect two or three quotes in exchange for a better price.

Typical installed cost: roughly $900 to $2,200 for a standard tank, per Angi and HomeAdvisor homeowner-reported ranges.
Advantage: No franchise or retail overhead built into the labor rate.

Independent licensed plumbers consistently quote the lowest installed prices in homeowner cost surveys, and they can install any brand you want rather than only what a program carries. The tradeoff is that you have to do the vetting yourself — license status, insurance, and whether the quote includes a permit.

Pros

• Usually the lowest installed price for a comparable job.
• Any brand, size, or fuel type you want, including heat pump models.
• You deal directly with the person doing the work.

Cons

• You verify licensing, insurance, and permits yourself.
• Warranty backing is only as strong as that one business.
• Availability for emergencies is hit or miss.

Who This Is Best For

The right choice when you have a week to gather quotes and want the best price. Avoid it if you would not know how to check a plumbing license in your state, or if you want a national warranty to fall back on.

How We Researched This

We built these rankings from published company service terms, manufacturer warranty documentation from Rheem and A.O. Smith, homeowner-reported cost ranges from Angi and HomeAdvisor, Better Business Bureau company profiles, and U.S. Department of Energy and ENERGY STAR guidance on water heater efficiency and equipment lifespan.

We excluded companies without verifiable multi-state coverage, single-city operators that cannot be compared nationally, and any provider that does not confirm licensed installation and permit handling. We did not accept payment from any company listed here in exchange for placement or ranking.

Cost figures are ranges, not quotes. Regional labor rates, local permit fees, gas versus electric, and code upgrades such as expansion tanks or new venting move the final number substantially.

Frequently Asked Questions

How much does water heater replacement cost in 2026?

Most homeowners pay roughly $900 to $3,000 to replace a standard 40 to 50 gallon tank, including the unit, labor, permit, and haul-away, based on homeowner-reported ranges from Angi and HomeAdvisor. Gas units, tight installation spaces, and required code upgrades push the total toward the high end.

Should I get a tank or a tankless water heater?

Tankless units cost more upfront but last longer and use less energy. The U.S. Department of Energy reports tankless units can be 8 to 34 percent more energy efficient than storage tanks, with the largest gains in homes using less hot water per day. If your household runs multiple showers at once, size the unit carefully or stay with a tank.

How long does a water heater last?

A conventional storage tank typically lasts 8 to 12 years. Tankless units often run 20 years or more with regular descaling. If yours is past 10 years and showing rust in the hot water or moisture around the base, plan the replacement rather than waiting for it to fail.

Do I need a permit to replace a water heater?

In most jurisdictions, yes. Water heater replacement usually requires a plumbing permit and often a mechanical permit for gas venting, followed by an inspection. Reputable installers pull the permit as part of the job. Unpermitted work can create problems when you sell the home.

How long does the installation take?

A like-for-like tank swap generally takes 2 to 4 hours. Converting from electric to gas, moving the unit, or installing tankless takes longer, often a full day, because it can involve new gas lines, venting, and electrical work.

Can I replace a water heater myself?

We do not recommend it. The work involves gas lines, combustion venting, or 240-volt wiring, plus pressure relief and expansion requirements that carry real fire, carbon monoxide, and flooding risk. Most manufacturer warranties also require licensed installation, and DIY work usually fails inspection.

What warranty should I expect?

Tank warranties commonly run 6, 9, or 12 years depending on model. Labor warranties are separate and typically run 1 to 2 years. Ask for both in writing, and confirm whether the labor warranty covers a full replacement visit or only the repair.

What size water heater do I need?

A rough guide: 30 to 40 gallons for 1 to 2 people, 40 to 50 gallons for 3 to 4, and 50 to 80 gallons for 5 or more. For tankless, sizing is based on flow rate and the temperature rise your incoming water requires, so a colder climate needs a larger unit for the same output.

Is a heat pump water heater worth it?

For many homes, yes. ENERGY STAR certified heat pump water heaters use significantly less electricity than standard electric resistance models, and utility rebates often offset part of the higher upfront cost. They need adequate air space and a drain, so confirm your installation location works before ordering.

How many quotes should I get?

Three, if the tank has not failed yet. Installed prices for the identical unit routinely vary by several hundred dollars in the same city. Ask each company to itemize the unit, labor, permit, haul-away, and any code upgrades so the quotes are actually comparable.
