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?

Scenario 1

The contractor was out of pocket up to 2-3 times his profit on the job, not to mention his strained relationship with his client.

  Scenario 2

The contractor's very livelihood is now threatened . And let us not forget that someone's child is dead.


Similar scenes are playing out across the country regularly.

Locking refrigerant caps are required in a majority of the United States under the 2009 IRC M1411.6 and IMC1101.10 - "Refrigerant circuit access ports located outdoors shall be fitted with locking-type tamper resistant caps".

Contractor ?
Is it worth the few bucks to install a life safety product even though the code is not enforced in your area?

Homeowner ?
If your service technician offers you this upgrade option while he is servicing your system , would you choose to save money by not accepting or would you be willing to save a life by spending a few dollars?
