Pre-season tune-up timingSchedule your AC tune-up in March-April, before the spring rush. Costs $80-150 and catches refrigerant issues before 100°F days hit.
System replacement triggerIf your system is 12+ years old and needs a major repair (compressor, coil), replacement is usually the better financial decision. R-22 refrigerant systems especially.
Heat pump mathHeat pumps are more efficient than gas furnaces for Central Texas's mild winters. If you're replacing your system, ask for a heat pump comparison quote.
