Houston is significantly harder than Atlanta — a difference that has major household implications. Appliances, boiler warranties, and detergent costs will differ substantially.
Moving from Atlanta to Houston?
If you're relocating from Atlanta to Houston, expect visible limescale on taps and shower heads within weeks. You'll need to recalibrate your dishwasher's salt setting, increase kettle descaling frequency, and check your boiler warranty requirements. A shower filter and under-sink scale inhibitor are worth considering immediately.
