That's and antique now. We've still got a few customers who have that vintage for AC units but all the HP's have been replaced. New Greenspeed HP sized more for heating than cooling would probably pay for itself in less than 2-years compared to what's currently there.
If YOU want change, YOU have to first change.
If you are waiting for the 'other guy' to change first, just remember, you're the 'other guy's' other guy. To continue to expect real change when you keep acting the same way as always, is folly. Won't happen. Real change will only happen when a majority of the people change the way they vote!
