good HVAC team is critical because we have noted that the
building management systems often are not flexible enough to
automatically deal with super extremes and require some
human intervention to tell them to do things like run heat
and cooling simultaneously. Other actions like closing down
louvers on evaporators may or may not be automated depending
on your systems. If any part of the system does fail in
these conditions you have to move super quick or you could
get serious damage fast. Our biggest monitoring points are
flow rate/pressure (which could indicate a freeze up
beginning or a pump failing), output and return temp on the
loops.</span></p>

This was one of the things I was concerned about, fluids going
smudgy or just simply freezing up...<br>
