Replacing a tankless in Mount Holly
A tankless that has failed is not automatically a tankless that needs replacing. Heat exchangers commonly carry twelve to fifteen year cover while the rest of the unit carries around five, and the exchanger is the most common terminal failure. We run the serial and check the warranty before quoting you for a new unit, because the part is frequently covered even when the labour is not.
Where a replacement is genuinely warranted, the second unit is usually a much simpler job than the first was: the gas line, the venting and the condensate route already exist and were sized once. In Mount Holly the permit goes through Gaston County for inspections and every trade permit, and a like-for-like swap in the same location is a considerably lighter permit question than the original conversion was.
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.

What Mount Holly itself changes
Where the heaters sit
Predominantly garage and closet installs in the post-2000 subdivisions, with crawlspace work in the older riverside core.
The pipe era
Copper and PEX in the bulk of the stock given the post-2000 build dates. A polybutylene layer in the smaller 1980s and 1990s portion, and older supply only in the historic core.
