Water Heater Repair Phoenix: $230 to $1,010 + APS Rebate

Phoenix rows are Angi's Phoenix figures (the repair row is from its emergency plumber guide). National rows are marked.

Do this now: a leaking or dead water heater

1. Leaking? Close the cold water valve on top of the heater, and switch off its breaker if it is electric.
2. Water from the bottom of the tank usually means the tank itself is damaged and must be replaced, HomeGuide says. Leaks from fittings, the drain valve or the relief valve may be fixable.
3. Smell gas? Leave the house and call the gas utility or 911 from outside. Water near outlets? Shut off power at the breaker only if you can reach it from a dry spot.
4. Water spreading across the floor? Shut the main and call the City's emergency line, 602-261-8000, if you cannot.
5. No hot water but no leak? Check the breaker or, on a gas unit, whether the pilot is out. HomeAdvisor says drafts can blow a pilot out; a relight runs $50 to $150.

Is it urgent? When a Phoenix water heater needs help today

A water heater is urgent when it leaks from the tank, smells of gas or the relief valve keeps discharging; no hot water alone can usually wait a day. HomeAdvisor says a tank lasts about 10 to 15 years, and the median Phoenix home was built in 1985, the Census Bureau's 2020 to 2024 survey shows, so a house that age has outlived two or more tanks at that rate. If yours is past 10 years and leaking from the bottom, price a replacement rather than a repair.

Water heater replacement in Phoenix: 2026 prices

Replacing a water heater in Phoenix averages about $1,224, with most homeowners paying $797 to $1,659, Angi's Phoenix guide shows. Tank-style units run $550 to $2,300 and tankless units $1,275 to $3,600 installed. Angi says Phoenix's hot desert climate makes both tankless and solar water heaters good options. For a like-for-like swap, a 40-gallon tank runs $750 to $2,100 and a 50-gallon tank $750 to $2,300 there.

Phoenix hard water and your water heater

Phoenix water is hard: the City's 2025 water quality report measured 172 to 302 ppm, or 10 to 17.6 grains per gallon. Ask about a flush and an anode rod check at every service visit; HomeAdvisor prices an anode rod at $50 to $150 installed, and HomeGuide puts a flush at $75 to $250. The City says softeners are generally not needed for safety and that if you use one, follow the manufacturer's maintenance instructions.

Water heater installation in Phoenix: permits and rules

Whether a Phoenix water heater swap needs a permit depends on which source you read, so ask the installer. The City's Work Exempt from Permit list (revised July 2014) says "replacement of an existing water heater in one- and two-family dwellings by a licensed contractor" is exempt, as long as the contractor checks the certification mark and follows the manufacturer's instructions. Angi's Phoenix guide says a permit is required, with a $75 minimum fee, and that solar units need their own permit. Switching to tankless or moving the heater is new work either way.

Owners who do the work themselves on a home they live in can use the City's owner affidavit under A.R.S. 32-1121.A.5. Anyone else should hire an ROC plumbing contractor (R-37R, R-37 or CR-37).

Questions to ask a Phoenix water heater company

1. What is your ROC license number?
2. Will you pull a permit for this swap, or is it exempt under the City list?
3. Repair or replace: what does each cost, and how old is my tank?
4. Will you flush the new tank or fit a softener-friendly anode, given our hard water?
