HVAC considerations in 78628
Straddles the Hill Country / Blackland Prairie line — ZIP can see a 4–5 mph wind speed difference between subdivisions on the same day, which matters for outdoor condenser siting in exposed lots. Lake Georgetown to the west moderates afternoon highs by 1–2°F vs eastern Georgetown 78626. The Feb 2021 ice storm and Jan 2024 freeze damaged copper line-sets on north-facing exterior walls — common across the ZIP's 2-story production homes. 2005–present production and semi-custom homes; many 2-story plans with a single system serving both floors — we frequently recommend a zoning damper retrofit here. Cimarron Hills (semi-custom golf-community) trends to larger 4–5 ton systems with mini-split additions for game rooms and detached casitas. Wolf Ranch and Rancho Sienna lean to high-efficiency variable-speed heat pumps from the original builder spec.
