Should I try to keep my system from running too much if I have a central system?Updated 9 months ago

If it's a non-inverter system, then yes. 

Every time your system starts up, it uses a lot of electricity and does not produce much cooling at that point. 

Usually, a system that is too small to cool the home is more economical to run but delivers less comfort. 

Even though it runs nonstop, it will usually consume less power than a larger system that cycles on and off. 

As a rule of thumb, a unit that is either on or off is less expensive than one cycling on and off. This is the technology behind inverter systems, where the system remains on, but at a low frequency. 

The data acquisition module on the indoor board will register the temperature via sensors and airflow, then it will modulate accordingly to provide a steady comfort level.
