Round Rock housing and HVAC
Most homes are single and two-story slab houses with attic systems, using gas furnaces or heat pumps. Many 1990s and 2000s homes are on aging first or second systems. Older homes near downtown date from the 1970s and 1980s with smaller attic systems, while newer two-story homes in Teravista and Paloma Lake often have one system per floor.
Round Rock has long, hot summers with highs often near 100°F and mild winters with occasional hard freezes, like Winter Storm Uri in 2021. Summer nights often stay in the mid-70s, so systems rarely rest from June through September, and spring storms can bring hail across Williamson County.
