Goodyear requires a city permit to replace a residential water heater, and that includes a switch to tankless. City water averaged 18 grains per gallon in the city's 2022 report, so scale control matters, and some neighborhoods are on Liberty Utilities water instead. Call the number on this page to be connected with a local plumber in Goodyear.
What happens when you call
You'll reach an independent plumber who works in Goodyear. The first questions are practical: is the current heater gas or electric, where is it, how old is it, and how many people shower in the morning rush. If you already have a tankless unit that's acting up, read off the error code and model number. For a new install, the plumber usually visits to check the gas meter, the vent path and where the condensate can drain. You'll get a description of the scope, the unit size recommended for your household and the permit steps before any work starts.
What affects the cost
- Gas line upsizing between the meter and the heater
- Vent material and length, and whether it exits a wall or the roof
- Condensing versus non-condensing unit
- Water treatment, since Goodyear water can be very hard
- Electrical work for the unit's controls or for an electric model
- The city permit, which carries an issuance fee and a unit fee
Goodyear conditions
Goodyear's housing is young, with a median build year around 2007, so most water heaters sit in garages with good access. The City of Goodyear blends groundwater from the West Salt River Valley aquifer with Colorado River water delivered through the SRP canal system and treated at the Goodyear Surface Water Treatment Plant. Its 2022 report listed hardness averaging 18 grains per gallon, with a very wide range of 4 to 49, and advised setting softeners at 14 to 20 grains per gallon. That's a strong case for protecting a tankless heat exchanger.
Not every address is on city water: Liberty Utilities serves parts of Goodyear, and the city's line at 623-882-7887 can confirm your provider. Southwest Gas holds the city's gas franchise. Permits go through Community Development, 195 N. 145th Ave., Building D, (623) 932-3004.
Before the plumber arrives
- Know whether your water bill comes from the city or Liberty
- Note your softener's current setting, if you have one
- Clear space around the heater and the gas meter
- Take a photo of the existing unit's label
- List the fixtures that run at the same time on a busy morning
- Check that the breaker or outlet near the heater works
If you smell gas, leave the house and call 911 and Southwest Gas at 877-860-6020 from outside.
