Something to think about ........
Scenario 1
A
contractor installs a new system in an upper middle
class neighborhood . Every thing works fine for a few
months until the homeowner calls to report her new
system is not cooling very well . The technician arrives
to find that the system is low on refrigerant. A leak
search is conducted , but no leak is found. So the
technician assumes that the new system was not properly
charged initially. He then adjusts the charge and
leaves. The call cost the contractor anywhere from $100
to $400 (not to mention lost revenue from a call he
could have been on). Everything works fine for a few
months until the home owner calls a second time to
report the same problem.
Once
again, the technician finds the system low on
refrigerant. He performs a leak search and after he
learns about the history of the system , he searches
again. He even puts on new service caps on the system
just in case. Once again , at a cost to the contractor,
the technician leaves with the system working fine.
 Three
weeks later the homeowner, not as sweet this time, calls
in a no cool call. This time, dispatch notices the
history with this system and assigns a different
technician, possibly a supervisor. Again , the system is
low on refrigerant and no leak is found. While this
technician gets ready to put dye into the system , he
starts looking around. He notices 'obvious signs
of multiple teenagers living in the area and remembers
what he heard about huffing (intentionally inhaling a
chemical for the purpose of getting "high") and a
product to help prevent it. So after a quick call to a
couple of local wholesalers and 45 minutes later, he is
back to install two NOVENT® Locking Refrigerant
Caps.
Six
months later, when the company returns for a scheduled
maintenance visit , the technician finds the system to
be fully charged and the home owner much happier.

Scenario 2
 About
two weeks after installing NOVENT® caps on the first
home, the contractor installs a new system in the same
upper middle class neighborhood about five blocks away.
But since he considered the first home an isolated inci-
dent, he did not install any locking refrigerant caps on
the second home. There were no reported problems for
about nine months. Then, unbeknown to the contractor,
the neighbor in the second home finds the body of a
neighbor- hood teenager near her unit.
After an investigation, it was determined that the
teenager had "huffed" Freon from the unit. Later, the
contractor is called out to check the unit. He adds 3
pounds of refrigerant , tells the homeowner about NO-
VENT® caps, and installs them. After the chatter that
follows such an event in a neighborhood, the lawyer for
the deceased's family asks the homeowner if they knew
about the locking refrigerant caps, were they required
by code , and why were the caps not installed?
Do we even
want to speculate what happens next?
