I'm in the market for a new HVAC system. I've noticed that the higher
SEER units jump dramatically in price going from 10 SEER to 12 to 14.
10-12 is an 85% increase. 12-14 is about %50 increase. I've also been
told that the 12+ SEERs have "variable" (valve can open/close to change
the pressure gradient) expansion valves. Lastly, these "variable"
expansion valves are prone to failure and frequent servicing.
Is this true

go with the highest you can afford. energy costs are going up, and will
never go down. also, pretty soon a 10 seer will be illegal to install.
