The A/C is supposed to be on unless it's below freezing outside - it dehumidifies the air and keeps the windows from fogging up. Just forget about it - it's normal.
 
It also lowers MPG a fair amount (1-2 MPG depending on vehicle). I leave my A/C off until I need it (sometimes in the rain, or if it's toasty outside. Otherwise, I leave it disengaged and save the fuel. By the way, I'm from the deep south and do understand humidity, but 100% A/C use is completely unnecessary. Put the system in auto in the warm months or on "foggy-window days," but you can leave it off otherwise.

Doesn't sound normal - are you turning the temp all the way up to 85 or 90 degrees? Is it in auto mode (is the auto button lit)? If it's on 90 and still not hot something's wrong. Could be a blend door or a bad heater core but I haven't heard any complaints from any Fusion/Milan/MKZ owners like that.

akirby probably already addressed this, but i agree you have to crank the temp up to get real heat. my explorer with digital temp readout is like this. in my focus i turn the temp dial(blue to red scale) all the way up as a matter of course, then turn down as it heats up.

You can set it to 70 and get the car to warm up quick if you are in Auto mode. Just press the auto button.

The dealer took a look at it....and apparently this has been a common problem for those with the automatic temperature controls (and noted many Lincoln owners were hoping this feature would be improved or eliminated).
 
Looks like if you have the automatic HVAC, regardless of running it on "auto" mode at 90 degree or having manually set with full fan on (again at 90 degrees), it will never be as hot as those with the manual, dial-mode HVAC
