What St. Johns's climate means for your Thermador oven
Summers on the First Coast run long and muggy, and a Thermador oven in St. Johns carries that load all season. Damp morning air can leave igniters slow to spark, and years of heat-cycling wear on door seals, elements, and control boards. We build that into the St. Johns visit itself — the climate-prone parts get checked whether or not they're the complaint.
