Hurricane Sandy and Flood Damaged Equipment


None of us like to hear about disasters like the recent damage caused by hurricane Sandy along the east coast. Our hearts and prayers go out to everyone affected by this disaster.

Now, as the clean up begins, the damage created by the storms in the Eastern part of the US, once again brings attention to the safety hazards involved with flood damaged HVAC equipment.

Submerged HVAC equipment typically is damaged beyond what would be considered cost-effective repair. Fully submerged equipment requires replacement of all open exposed electrical controls and motors. Likewise, gas piping, controls and burner systems require a combination of component part replacement and cleaning to assure proper, safe operation.

In addition, submerged air handling or duct systems are subjected to the potential biological hazards caused by contaminated flood water and sewer back-up getting into the system. This can also get into the unit insulation and can create molds and other problems.

It is strongly recommended that complete equipment change-out coupled with a thorough duct system replacement or cleaning is likely the action required to restore safe, reliable HVAC system operation.

It is also strongly recommended that all flood damaged HVAC systems remain off-line until properly inspected and dispositioned by a skilled HVAC professional.

We all hope that we are never in this position but, when it does happen, it is always best to “do it right the first time” and avoid a possible second disaster because we tried to short cut the initial repair.

As I said above, our hearts and prayers go out to all those affected by hurrican Sandy and it is our hope that the lives of those affect by this disaster can be quickly restored to normal.

About yorkcentraltechtalk

I have been in the HVAC industry most of my life. I worked 25 years for contractors on anything from residential to large commercial boilers and power burners. For the past 23+ years I had been employed by York International UPG Division ( a division of Johnson Controls) as a Technical support/Service Manager but I am now retired. One of my goals has always been to "educate" dealers and contractors. The reason for starting this blog was to share some knowledge, thoughts, ideas, etc with anyone who takes the time to read it. The contents of this blog are my own opinions, thoughts, experiences and should not be construed as those of Johnson Controls York UPG in any way. I hope you find this a help. I always welcome comments and suggestions for postings and will do my best to address any thoughts, questions, or topics you may want to hear about. Thanks for taking the time to read my postings!
