How old are Lakeway's homes — and their HVAC systems?

The median home dates to 2004, and 36% were built in 2010 or later^[1]. Your own system may have been replaced since — the outdoor unit's data plate shows when it was made.

14% of Lakeway's housing units were built before 1980, 2.2% before 1960^[1] — the 3rd-highest share of the 15 Austin-area suburbs we cover. The ductwork in an older house is often original even when the equipment is not — ask for a duct leakage check with any replacement quote.
