Descaling on Mount Holly water
Manufacturers write one descaling interval for the whole country, and it is set for hard water. Yours comes from the City of Mount Holly, and where that supply is soft the exchanger fouls considerably more slowly than that schedule assumes.
We will tell you honestly where you sit on that, because the alternative is descaling a unit annually that does not need it. Two caveats worth knowing before you skip it entirely: some manufacturers require documented annual servicing to keep the heat exchanger warranty valid, which is worth more than the service costs, and a property on a private well is a completely different conversation from one on the municipal supply.
- Descale on an interval that matches your actual water rather than the manual's default.
- Inlet filter clean, which is the most commonly skipped job and the cheapest.
- Flow rate and combustion check, so a declining unit is caught before it fails in January.

What Mount Holly itself changes
The housing in Mount Holly
Mount Holly is newer than the Gaston County average and newer than Mecklenburg, which surprises people who expect the whole county to be old housing. 49.1% of the stock has been built since 2000 and the median value sits at $337,800. Writing this market off as aging housing stock, the way a lot of Gaston County content does, gets it wrong.
Where the heaters sit
Predominantly garage and closet installs in the post-2000 subdivisions, with crawlspace work in the older riverside core.
