Specialists rather than general plumbers, this Phoenix outfit works on tank and tankless water heaters only: repairs, maintenance, replacements and hot water recirculation pumps, for houses as well as commercial buildings. The company says it has been trading since 1968 and has serviced more than 1.2 million units, and it names Bradford White, Rheem, GE, AO Smith and American Standard among the brands it installs. Coverage runs across the Valley, with a Phoenix branch and a Mesa branch listed and service areas including Chandler, Tempe, Gilbert, Glendale, Peoria, Scottsdale and Surprise. Published hours show 24 hours a day, seven days a week, and the company states that nights, weekends and holidays carry no extra charge. Its Google Business Profile shows 4.9 from 651 reviews, read on September 27, 2026. Best suited to anyone who has lost hot water and wants a same-day fix from someone who does nothing else. Not the call for a blocked drain or a leaking hose bib.

  • Best for same-day water heater repair and replacement anywhere in the valley
  • 4.9 from 651 reviews on its Google Business Profile, read September 27, 2026
  • No drain cleaning, repipes or general plumbing, so you may still need a second contractor

Editorial Review

Our Take on Water Heaters Only, Inc.

Single-trade specialists tend to be either very good or very limited, and the review volume here points to the former. The 4.9 average from 651 Google reviews, read on September 27, 2026, is the sort of record that is hard to fake over time, and the 24/7 answering with no stated after-hours surcharge is a genuine differentiator in a market where emergency premiums are common. Just remember the scope: heaters, and nothing else.

About Water Heaters Only, Inc.

Narrow focus is the whole proposition here. Where a general plumbing company might rotate between drain cleaning, repipes, fixture swaps and the occasional heater changeout, this business keeps its technicians on one appliance, and that shows up in the small things: knowing which Bradford White model fits a tight 1970s hall closet, carrying the right gas flex and drip leg on the van, understanding what Phoenix inspectors expect to see on a seismic-free but code-heavy install. Water heaters only inc lists residential repair, maintenance and replacement, commercial repair and replacement, and hot water recirculation pump installation. That is the range, and it does not pretend otherwise.

The Phoenix water supply is the real driver of demand. Valley water is hard, and the mineral load settles as a layer of scale on the bottom of a gas tank, insulating the burner from the water above it. The result is longer recovery times, a rumbling or popping noise, and a tank that dies years earlier than the sticker suggested. Anode rods go the same way, sacrificing themselves faster in mineral-rich water, which is why a flush and rod check every couple of years is worth more here than in softer-water cities. A technician who works on heaters all day will tell you quickly whether a unit is worth a thermocouple or a gas valve, or whether you are pouring money into a tank with a failing glass lining.

Summer heat matters too. Garage installs in Phoenix sit in ambient temperatures that push past 120 degrees, which is hard on electronics and expansion tanks, and it also means a leaking tank in a garage can go unnoticed for days. Many Valley homes have the heater in the garage on a raised platform or in an exterior closet, which usually makes replacement quicker than in a two-storey house with the unit upstairs in a pan above finished ceilings. If yours is upstairs, ask specifically about pan and drain line requirements and what happens if the existing pan has rusted through.

Day to day, the company says phones are answered by a live person at any hour and that a certified technician is dispatched from that call rather than a message being taken. Published hours back the 24/7 claim, and the stated policy of no surcharge for evenings, weekends or holidays is unusual enough to be worth confirming when you book. Same-day repair and replacement is advertised, along with a promise to meet or beat competitors' onsite bids and 0 percent deferred interest financing for up to six months. Those are the company's own claims, so get them restated in writing on the quote.

Who it suits: a homeowner with cold showers this morning, a landlord who needs a unit swapped before a tenant complains again, a property manager with a commercial tank down and a building full of people. Who it does not suit: anyone shopping for a whole-house repipe, slab leak detection, sewer scoping or a bathroom remodel. For those jobs you want a full-service plumber, and it is reasonable to keep two numbers in your phone.

Before hiring, ask a few concrete questions. Is a City of Phoenix permit being pulled, and is inspection included in the price. Will the install bring the connections up to current code, including expansion tank, seismic strapping if applicable, drain pan and correct venting for a gas unit. What is the manufacturer warranty on the tank versus the labour warranty from the installer, and who handles a warranty claim in year four. Is the old unit hauled away. If you are weighing tankless, ask honestly about gas line sizing and venting costs, because in older Phoenix housing stock those upgrades often cost more than the appliance.

On evidence, the Google Business Profile for water heaters only inc shows 4.9 from 651 reviews as read on September 27, 2026, which is a strong average on a solid volume. The company separately advertises 4.8 from 5,850 reviews across its own channels, a figure it publishes itself and one a reader cannot independently verify. Compared with the Valley's larger plumbing and HVAC firms, which often sell heaters as part of a broader membership package, the trade-off is straightforward: less breadth, more depth, and a shorter conversation about what you actually need.

Water Heaters Only, Inc. FAQs

  • Do they really answer the phone at 2am?

    Published hours show open 24 hours every day of the week, and the company states that calls are answered by a live representative at any hour rather than going to a recording. It also says a technician can be dispatched from that call. If you have water on the garage floor, shutting off the cold inlet valve and the gas or breaker before you ring is still the sensible first move.

  • Is there a surcharge for weekend or holiday calls?

    The company states it does not charge extra for evenings, weekends or holidays. That is its own published policy, so it is worth having the technician confirm the rate on the phone before dispatch and again on the written quote.

  • How is water heaters only inc rated?

    Its Google Business Profile showed 4.9 from 651 reviews when read on September 27, 2026. The company separately advertises 4.8 out of 5 from 5,850 reviews gathered across its own channels, which is a self-published figure rather than an independently checked one.

  • Will they fix a blocked drain or a leaking tap as well?

    No. The listed services cover water heater repair, maintenance and replacement, plus hot water recirculation pumps, for both homes and commercial buildings. For drains, sewer lines, repipes or fixtures you will need a general plumbing company.

  • Why do water heaters fail so fast in Phoenix?

    Hard water is the main reason. Valley water carries a heavy mineral load that settles as scale on the tank bottom, which insulates the burner, slows recovery and causes the popping sound many homeowners notice. The sacrificial anode rod also depletes faster in mineral-rich water, so periodic flushing and a rod check can add years to a tank's life.

  • Can they replace a heater the same day I call?

    Same-day repair and replacement is advertised, including for commercial units. Whether it happens depends on the time of day, the model you need and how accessible the unit is. An upstairs install sitting in a pan above finished ceilings generally takes longer than a garage swap.

  • What should I ask before agreeing to a replacement quote?

    Ask whether a City of Phoenix permit and inspection are included, what code upgrades the price covers such as expansion tank, drain pan and venting, how the manufacturer tank warranty differs from the installer's labour warranty, and whether the old unit is hauled away. The company advertises 0 percent deferred interest financing for up to six months and a promise to meet or beat competitors' onsite bids, both of which should be put in writing.

  • Is Water Heaters Only, Inc. licensed and insured?

    We have no credential records on file for this company yet. Ask for the certificate directly from the insurer before booking work.

  • What areas does Water Heaters Only, Inc. serve?

    Phoenix. Coverage is as the business describes it, cross-checked against where its recent documented work is. Confirm your address before scheduling, particularly at the edge of a service area.

  • Does Water Heaters Only, Inc. offer emergency service?

    Emergency availability is not listed for this company. If you need an urgent call-out, check the ranking for companies that do list it.

  • What warranty do they offer?

    Warranty terms are not on file. Ask for them in writing before work starts.

  • How was this profile built?

    Credentials come from issuing authorities, ratings from the company's Google Business Profile with the date we read them, and the editorial take from our own review of estimates, warranty documents and public feedback. Anything the business told us is labelled as reported.

  • Can a business pay to improve its profile?

    A business can subscribe to manage its own listing details, and it can buy a labelled sponsored placement. Neither changes a ranking position or the editorial assessment on this page.
