Post Sandy Recovery Guidance from AEA
We at AEA offer the following guidance in the continuing efforts to recover from Sandy:
Safety – we urge everyone to use caution in all aspects of recovery efforts; the situation can have many hazards – exposure to mold and mildew or asbestos, use of emergency generators, electrical hazards, and many others. Consult experts in any situation where these hazards may exist.
If insulation in walls or ceiling cavities has become waterlogged, the insulation should be removed as soon as possible, along with other damaged building materials, to minimize the danger of mold and mildew formation.
Electronic componentsthat were wetted thoroughly, even if only for an instant, are almost certainly destroyed, and should be replaced.
Electrical equipment that was submerged briefly in fresh water likely can be dried/cleaned and put back in service; however, if the water was briny, or if it was wet for several days, then the likelihood is that at least the electrical contact parts will have to be replaced. An experienced, licensed electrician should make these decisions.
Similarly, electric motors that were submerged should be replaced.Pumps that were submerged for extended periods, or in briny water should be re-built; it’s likely that the seal assemblies have been damaged. The major components – impeller, casing, and shaft likely would not be damaged.
As for boilers, following applies:Residential and small commercial boilers and water heaters that have been submerged should generally be replaced. Cast Iron and steel boilers which were not in operation when the flooding occurred would only have superficial rusting, and generally do not need to be replaced. If the shell insulation has been damaged or saturated with briny water, it should be replaced. If a boiler was in operation at the time of the flooding, then there is the possibility of serious damage, and the boiler should be carefully inspected by an experienced and qualified boiler mechanic. All controls and safety devices that were affected should be replaced.
Burners and gas trains should be replaced in their entirety.
Time clocks and other controls that were not water damaged, but lost power, should be checked and may need to be reset.

When equipment or materials are to be replaced, whether HVAC equipment, lighting, insulation, or other, consider replacing with equipment or materials which that are properly and of optimum efficiency; remember that many existing heating systems are grossly oversized, and right-sized equipment save money initially and through the life of the system. Contact Bob Gardella at AEA 718.292.6733, ext. 8006 if you need assistance with sizing, selection, or design of replacement systems.
We wish you and your loved ones a safe, healthy and energy-efficient recovery from this disaster.
