What is the '3-minute rule' for AC systems?
The '3-minute rule' for AC systems suggests waiting at least three minutes after turning off your AC before turning it back on. This allows the system's internal pressures to equalize. Turning it on and off rapidly can strain the compressor, potentially leading to costly repairs for your Allentown home's system.
This rule isn't absolute and depends on the age of your current system and its overall condition. Pros can help you evaluate this for your Allentown home.
