Why the local crew matters

Arizona is not one plumbing environment. Hard water in the Valley scales water heaters and narrows supply lines. Freezes in Flagstaff, Prescott, Payson and the White Mountains split exposed pipe every winter. Heat along the Colorado River corridor destroys plastic fittings on roofs and exterior walls. Well and septic systems change how a problem is diagnosed across rural Arizona entirely.

How a call goes

Three steps, no surprises

The order matters, so we have numbered it. Nothing starts until you have agreed a price.

You call, a person answers

Tell us what you are seeing, hearing or smelling. We will narrow it down on the phone, tell you what it most likely is, and give you an arrival window in Arizona.

We diagnose before we quote

Cameras, meters, pressure tests and listening equipment as needed. You get told what actually failed and why, not just what it will cost.

Flat price, then the work

You approve a fixed number before anything starts. We finish in one visit wherever the parts allow, clean up, and back the workmanship in writing.

Answers

Frequently asked questions

How long does installation take?

A straight swap with adequate gas and venting is usually a day. A conversion from a tank that needs gas upsizing, new venting and condensate routing runs longer, and we will tell you which one yours is before you commit.

Can a tankless unit run two showers at once?

It depends on sizing. That is exactly why we size on fixture count and incoming water temperature rather than selling everyone the same box.

Will my gas line handle a tankless unit?

Often not without a change. Tankless heaters draw far more gas at peak than a tank does, so we check line size and meter capacity as part of the quote rather than discovering it on install day.

Is tankless worth it in Arizona?

If you run out of hot water regularly, want the floor space back, or plan to stay in the house long enough to recover the install cost through lower standby losses, yes. If you have one bathroom and modest demand, a good tank may serve you better.

Does hard water damage a tankless heater?

It scales the heat exchanger, which is the expensive part. In Arizona we fit isolation valves at install and recommend annual descaling. With softened water, intervals stretch out.

What should I do while I wait for the plumber?

If water is escaping, shut off the supply. There is usually an isolation valve at the fixture and a main shut-off where the line enters the property or at the meter. If it is a gas smell, leave the building first and call from outside. Then call (888) 809-6756.

Are you open right now?

Yes. Rolland Plumbing Service runs a 24 hour plumber service in Arizona every day of the year, including weekends and public holidays. There is no separate after-hours rate, so a 2am call costs the same as a 2pm one.

Do you serve areas outside Arizona?

We cover every city in Arizona. If you are just outside Arizona we almost certainly still come to you, and there is no travel surcharge for surrounding communities.

What customers say

Tankless Water Heaters reviews from around Arizona

★★★★★

The quote was the price. That sounds like a low bar but it is not, based on my last few experiences with contractors here in Arizona.

I manage several rentals in Arizona and I now just use one number for all of them. They deal with the tenants directly, send me the photos and the invoice, and I do not have to chase anybody.

Holly K.Homeowner · Arizona, AZ
★★★★★

Old tank heater on a Sunday, which of course it was. No weekend surcharge, no lecture, just sorted it. I have already given the number to two neighbours.
