Why it matters to you
After widespread outages such as Hurricane Beryl in July 2024, some Greater Houston outdoor units would not restart because of tripped protection or storm-damaged parts. The disconnect is also where a technician isolates power before working on the capacitor or contactor.
Practical guidance
If the outdoor unit will not restart after an outage, wait several minutes, confirm the thermostat is on and set to cool, then call for service. Do not open the disconnect box, pull its block or replace its fuses yourself; a rusted or damaged disconnect should be replaced by a licensed technician.
