Tankless Water Heater Installation & Repair
Hot water on demand, without a tank. Western Sky Plumbing installs and repairs tankless water heaters across the Phoenix Valley. We're an Authorized Rinnai Pro, one of six in Arizona, and we work with Navien and Trutankless as well.
KNOW THE SIGNS
Signs you need this
You're replacing a tank and want endless hot water
Your tankless unit shows an error code or won't fire
Hot water fluctuates or runs cold mid-shower
Scale buildup from hard water is slowing the unit down
You need more hot water capacity than a single tank provides
HOW WE DO IT
A clear, three-step approach.
01
Size it
We size the tankless unit to your home's hot water demand and check gas, venting or electrical requirements.
02
Install or repair
New installations, conversions from tank to tankless, and repairs on existing units.
03
Protect it
Hard water leaves scale inside tankless units. Ask us about a water softener to help protect it.
Navien and Trutankless
We also install Navien tankless water heaters, and we're a preferred Trutankless installer. Trutankless units are electric tankless water heaters.
Tankless water heater repair in Phoenix
We repair tankless water heaters from all brands. Hard water leaves scale inside the heat exchanger over time, and a water softener can help reduce it.
