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.
