What drives the price in Austin
- Heat wave surge: in a 100F+ stretch, same-day capacity disappears. Set honest expectations and call early in the day.
- Age rule for Austin: if the unit is 12+ years old, uses R-22, and the repair is over $1,500, replacement usually wins. Show the math, do not just assert it.
- Cedar and dust load clog filters and coils faster. Maintenance cost block: tune-up $89 to $189 typical.
Permit and code note
No permit for most like-for-like repairs. Permit applies when equipment is replaced, gas lines are altered, or electrical is upgraded. If a repair quote turns into a replacement quote, the permit note from the replacement pages applies.
Austin example
Example: a 12-year-old unit in 78745 with a failed capacitor on a 102F day. Capacitor swap typically lands near $250. If the same unit needed a $2,600 compressor, replacement usually wins.
