Central Texas heat combined with humidity creates extreme demand on cooling systems from May through September—your AC isn't just fighting temperature, it's also removing moisture from the air. That humidity also accelerates refrigerant loss and corrosion on outdoor units, especially in areas near Lake Travis where salt spray affects equipment faster than in inland neighborhoods.

Austin's hard mineral-rich water causes calcium and lime buildup in condenser coils within 18-24 months of regular operation, and airborne cedar pollen (especially November through February) clogs filters faster than typical climates. Many homes skip spring maintenance and then face mid-June breakdowns when all the local HVAC contractors are booked solid for two weeks.

Schedule your AC maintenance in April or early May, before the summer crush hits—this gives you time to replace worn capacitors, clean coils affected by mineral deposits, and catch refrigerant leaks before peak demand arrives. If you're in Cedar Park or the northern suburbs, your system faces even harder use due to higher elevation and intense afternoon sun exposure on west-facing units.

Spring prep (April-May) is non-negotiable in Austin; a neglected system entering June will cost you in both emergency repairs and wasted energy. If you haven't had maintenance done since last fall, a pre-summer inspection now will identify whether you're heading into August with a reliable system or a breakdown waiting to happen.
