Descaling on Pineville water
Manufacturers write one descaling interval for the whole country, and it is set for hard water. Yours comes from Charlotte Water, 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 Pineville itself changes
The housing in Pineville
Pineville has been its own town since 1873 and the housing reflects a long build history: 21% went up in the 2000s and 22.1% between 2010 and 2019, over a genuinely old core. The median build year is around 1999, which puts a large share of the town in the second-heater band.
Where the heaters sit
Garage and closet installs in the newer builds, crawlspace through the older centre. Attic units in the larger two-storey homes.
