Replacing a tankless in Mint Hill
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 Mint Hill the permit goes through Mecklenburg County, and a like-for-like swap in the same location is a considerably lighter permit question than the original conversion was.
Mint Hill is an old farming town with two distinct housing waves rather than one. The 2000s are the single biggest decade at 22.0%, but the 1970s and 1980s together account for 35.0%, which is a larger share and gives Mint Hill the largest 1970s cohort of anywhere in this study. Those older homes are on their third or fourth water heater, and they are the ones where nobody has ever checked an anode rod.

What Mint Hill itself changes
Where the heaters sit
Garage and crawlspace both common, reflecting the two build waves. The 1970s and 1980s stock frequently has tighter access than the newer subdivisions, and we price that before the visit.
The pipe era
A genuine polybutylene layer in the 1978 to 1997 portion, which is substantial here. Copper in the 1960s and 1970s stock. PEX in the 2000s builds.
