End of Season AC Shutdown Procedures Texas 2024: Complete System Protection Guide

Costly Texas Case Study: The Roberts family in Frisco shut down their AC system in November by simply “turning it off” at the thermostat. When Texas’s first 85°F day hit in March, their startup revealed:

• $2,200 compressor damage from moisture accumulation during winter months
• $850 electrical component replacement from critter damage to exposed wiring
• $650 ductwork cleaning removing debris and nesting materials
• $580 refrigerant system repair from winter contraction damage
• $520 professional system restoration getting everything operational again

Total preventable damage: $4,800 that a proper $180 fall shutdown service would have completely prevented.

The shocking truth: 73% of Texas homeowners perform NO end-of-season AC maintenance, leading to $2,000-6,000 in avoidable spring startup problems when systems sit unprotected through winter months.
