I'm assuming you're talking about installing a HVAC system that has a readout of the temperature that you want it to stay at?
If all the sensors and actuator hardware, along with the control unit (properly programmed) comes with whatever you're buying, then it shouldnt be too hard... Just a matter of placing stuff and wiring it.
What exactly are you buying?
