Replacing a tankless in Cornelius
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 Cornelius 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.
Cornelius is a solid fit for second-cycle water heater work: 24.1% of the stock was built in the 1990s and 32.5% in the 2000s, giving a median build year of 2002. That is a large, consistent cohort of homes whose original units have already been replaced once and whose replacements are now aging out.
What Cornelius itself changes
Where the heaters sit
Garage and closet installs across the subdivisions, with attic units in the larger lakefront and near-lake homes. Access is generally good.
The pipe era
Copper and PEX through most of the stock, with polybutylene possible in the earlier 1990s portion. Supply pipework is rarely the cause of hot water complaints here.
