Gas tank
The workhorse. Simple, serviceable, keeps working in a power cut. Needs correct venting and combustion air, both checked at altitude.

Water heater replacement in Flagstaff, AZ
When the tank is done, the job is more than swapping a box: it's sizing for elevation, meeting current code, pulling the permit and passing the inspection. That whole job is the quote. No surprise line items on the day.

Scheduled, not scrambled
What replacement day actually looks like
Drain and disconnect
Water off, tank drained, gas or power isolated. Floors protected on the way in and out.
Set and connect the new unit
New tank set level, connected with new flex lines and a new T&P discharge run to code, plus the expansion tank and seismic strapping where the code calls for them.
Test everything hot
Gas joints leak-tested, temperature dialed in, relief valve verified, combustion air and venting checked at altitude.
Inspection and haul-away
We schedule the city or county inspection, meet it, and recycle your old tank at no added cost. You keep the permit paperwork.
Sized for elevation
Why sizing is different at 7,000 feet
A gas heater that keeps up with a family of four in Phoenix can lag behind the same family in Flagstaff. Above 2,000 feet the fuel code requires input adjustments, and up here the groundwater arrives colder too, so recovery (the speed a tank reheats) is squeezed twice. We size from the manufacturer's altitude tables and your real household, not from the box label.
Electric tank
No combustion, no flue, no altitude derate on the elements. Slower recovery, so honest sizing matters even more.
Thinking tankless?
A different conversation: venting, gas line sizing and altitude certification all change. Read the tankless page before you decide.
Straight answers
Replacement questions, answered plainly
Do I really need a permit to replace a water heater in Flagstaff?
Yes. In Flagstaff and Coconino County a water heater replacement requires a building permit and inspection. We pull it and meet the inspector on every replacement. It protects your insurance, your resale paperwork and your warranty.
Can you match the size I already have?
We can, but we will check first whether the old size was ever right. Codes change, families change, and altitude sizing gets skipped constantly. If your old 40-gallon always ran out on Sunday mornings, this is the moment to fix that.
What happens to my old tank?
It leaves on our van the same visit and goes to metal recycling. No added charge, no tank sitting by the curb.
