Re: Is the activent really going to save me 30% $$$ per year on energy bills?
Rolland we don't have A/C, just heat where we manually set all our duct vents specifically to get the desired temp in each room. took a while to get it right but ... it works.
House temp is controlled by a programmable thermostat.
Don't see why A/C would not work the same or may need slight seasonal adjustment.
