Smithville, down the Colorado River from Bastrop on SH 71, has the oldest housing on this line. Its median build year is 1987, four homes in ten predate 1980, and inside the town itself the median is 1967. Old houses here are on their third or fourth AC, and the ductwork is often older than all of them.
The weather station is here
The NOAA normals this site quotes for the Bastrop area come from the cooperative station in Smithville: about 124 days a year at 90°F or above, 22 at 100°F or above, 34 nights at or below freezing, and an average August high of 97.0°F (1991–2020). Smithville's numbers are not an estimate from somewhere else; they are measured in town.
Old houses, older ducts
In a house built before 1980 the system has usually been replaced several times, each time onto ductwork sized for the first one. That shows up as rooms that never reach the setting, a return that whistles, or a new AC that performs no better than the old one did. When a replacement is quoted for an older Smithville house, ask what was measured on the duct and return side, not only the tonnage.
Some older houses also carry systems that are themselves old: an AC installed before 2010 may still run on R-22, which has not been produced or imported since 2020. A large refrigerant repair on one of those is usually priced against AC replacement.
More gas than most of the ring
27% of homes in 78957 heat with piped natural gas, the highest share on this line; in town it is about half. That means more gas furnaces, more flame sensors and ignitors on the first cold morning, and a heat exchanger to ask about on any furnace past twenty seasons. If you smell gas or a carbon monoxide alarm sounds, leave the house and call 911 or the gas provider from outside first.
Renters and owners
About a quarter of homes in the ZIP code are rented, more in town. A replacement is the owner's decision; if you rent, the call that gets a system fixed is usually the one to the property owner.
What to say when you call
- The age of the house and of the system, if known
- Gas, electric or heat pump
- Which rooms are worst, and whether it is airflow or temperature
- Where the indoor unit sits: attic, closet or a hall return
Questions from 78957
A new AC did not fix the hot back room. The duct run or the return probably did not change with it. Ask a technician to measure airflow at that register.
The gas furnace is very old but still lights. Ask for combustion and carbon monoxide readings in writing at the next service visit.
Know the symptom and the install year? That is enough to start. Ask whether a contractor is taking calls in your ZIP code today.
