I’m working on an in-depth article about how long air conditioners can run continuously and the factors affecting performance, efficiency, and lifespan. I’m seeking insights from HVAC professionals, technicians, or energy experts on: • How long a typical central AC or mini-split system can safely run without stopping. • Whether it’s normal for AC units to run all day during extreme heat. • Signs that continuous running indicates a problem. • How continuous operation impacts energy consumption and system lifespan. • The role of smart thermostats or automation in optimizing run cycles.
