Mountainaire homeowners call Liberty for tankless water heaters because we're local to the high country, licensed, and answer the phone 24/7. Mountainaire sits at about 6,950 feet in the pines south of Flagstaff, taking in the Mountainaire and Kachina Hills subdivisions. Out here it is mostly wells, septic, and cabins that sit empty part of the year, so freeze protection and winterization are the bread and butter. Real licensed crew, straight answers, fair quote before we touch a thing.

Mountainaire runs right up against the Coconino National Forest at close to 6,952 feet, and the housing is a mix of full-time homes and part-time places in the pines. Unlike neighboring Kachina Village, most of Mountainaire is not on a water and sewer district, which means private wells, pressure tanks, and septic systems doing the work. Every one of those adds freeze-prone components outside the heated envelope of the house, and at this elevation the freeze season is long enough that a shallow or uninsulated run will eventually find its limit.

What we see on Mountainaire plumbing

  • Deep winter freezes at nearly 7,000 feet on well lines, hose bibs, and unheated crawlspace plumbing.
  • Private wells and septic systems that need the plumbing side maintained on both supply and drain.

How a Mountainaire tankless water heaters call goes

  1. Gas & venting check

    Tankless needs adequate gas supply and sealed venting, we verify your line can feed it before quoting.

  2. Scale protection built in

    We pair every install with a softener or an isolation/scale-filter kit so AZ minerals don't choke it.

  3. Annual descale plan

    We set you up on a yearly flush so the warranty stays valid and flow stays full.

Tankless Water Heaters in Mountainaire, FAQ

Is tankless worth it in Arizona?
Yes, if you stay on top of the annual descaling. Our hard water will clog an unmaintained unit fast. Put a softener in front of it and it's a 20-year appliance.
Can my gas line handle it?
More often than not the existing line is undersized for a tankless burner. We measure it and upsize if it needs it, and that's part of the quote.
Do I really need a water softener with a tankless heater in Phoenix?
Pretty much, yes. Our 16-20 grain water scales the narrow heat exchanger fast, and unsoftened water can ruin a tankless unit in a couple of years. Soften the water and descale it yearly and a tankless will reach its long lifespan out here.
How often does a tankless need to be flushed?
About once a year in our hard water, and more often if you don't have a softener. Units with isolation valves make the descaling flush quick. If yours doesn't have them, adding them is worth the trouble.
Will a tankless give me unlimited hot water for the whole house?
It won't run out of hot water, but flow rate is the limit. Run two showers and a dishwasher at once and you can outrun a single unit, especially in winter when the incoming water comes in colder. Size it right for your peak demand and it works.
Why does converting from a tank to tankless cost more than I expected?
Gas tankless units usually need a bigger gas line and a new sealed vent, and electric models can mean a major panel upgrade. Those home-infrastructure changes, not the unit itself, are what drive the retrofit cost. We'll size all of it up front.
Does a tankless work as well in Flagstaff as in Phoenix?
It works, but the incoming water up north runs colder, so the unit has to raise the temperature further. That drops its effective flow rate. A unit sized right for Phoenix may need to be bigger to do the same job in the high country.
I leave my Mountainaire place empty over the winter. What should I do?
Winterize it, and do not rely on leaving the heat set low and hoping. We drain the system, blow out the supply lines, protect the traps with antifreeze, and shut it down properly so there is no water sitting in a pipe at 6,950 feet in January. Come spring we bring it back up and check every line and fixture for damage before you turn it over to a house full of guests.
