Replacing a tankless in Davidson
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 Davidson the permit goes through Mecklenburg County alongside Town of Davidson planning, and a like-for-like swap in the same location is a considerably lighter permit question than the original conversion was.
Davidson is a college town with a genuinely old centre around the campus and a steady stream of newer building around it, some of it very recent. The older houses near the college have the problems old houses have: tight utility spaces, heaters fitted where there was room rather than where there should have been, and discharge pipes that were run before anyone was checking. The newer building is straightforward by comparison.
What Davidson itself changes
Where the heaters sit
Utility room, closet and crawlspace in the older centre. Garage and attic in the newer subdivisions. Attic installs are the ones we want to know about on the phone, because a leak in an attic is a different urgency from a leak in a garage.
The pipe era
Mixed with the build years. The oldest properties near the campus may have galvanised in service; the newer stock is copper and PEX.
