This information is created from Lennox Application Note ACC-63-11

Flood Damaged Heating & A/C Equipment

10/9/2015

In the event Lennox HVAC equipment has been flood damaged or rendered inoperable due to a severe storm, the following steps should be taken before returning the equipment to operation:

  • Any unit that is or has been partially or completely submerged must have the electrical power supply disconnected immediately. The fuel supply to gas or oil burning equipment must be shut off.
  • Complete equipment service must be performed on the equipment. Safe and proper operation of the equipment must be verified. Failure to do so can cause further property damage and/or personal injury.
  • The extent of the damage will depend on the depth of the flood water, water type (fresh, brackish, etc) and the length of time that the unit was submerged.

Gas or Oil Furnaces & Heating Sections of Residential Package Units

  1. Ensure the electrical power supply to the equipment is off.
  2. The equipment must be thoroughly cleaned. This may require removal and disassembly dependent upon depth of water and length of time submerged.
  3. All electrical and safety components, such as those listed below, that have been under water must be removed and replaced with a new part:
    • Ignition control
    • Gas valve
    • Primary and secondary limits
    • Flame rollout switch
    • Combustion air inducer and pressure switch
    • Igniter
    • Blower motors
  4. Burners that have been under water must be thoroughly cleaned and/or replaced.
  5. Equipment insulation is secured to the cabinet with water-soluble glue. If insulation has been under water, it must be replaced with insulation of the same type, density and thickness as the original.
  6. Clean and thoroughly dry all electrical connections and any damaged wiring must be replaced.
  7. After repairs have been completed, an operational safety check must be performed on the equipment.
  8. The correct operation of all safety devices must be verified.

Air Conditioning or Heat Pump Systems & Refrigerant Sections of Residential Package Units

If the refrigerant circuit is damaged resulting in a refrigerant leak or is open to the atmosphere and has been under water, the complete system – (outdoor unit, refrigerant lines and evaporator or air handler) must be replaced.

If the refrigerant circuit is NOT open to the atmosphere, the following steps must be taken:

  1. Ensure the electrical power supply to the system is off.
  2. The equipment must be thoroughly cleaned, including the outdoor coil and evaporator in a furnace or air handler installation. This may require removal and disassembly dependent upon depth of water and length of time submerged.
  3. All electrical and safety components, such as those listed below, that have been under water must be removed and replaced with a new part: (this applies to both the indoor and outdoor equipment)
    • Electronic controls, defrost controls or electric heat controls and sequencers
    • Contactors
    • Motors
    • Refrigerant Pressure Switches (non-hermetically sealed)
  4. Equipment insulation is secured to the cabinet with water-soluble glue. If insulation has been under water, it must be replaced with insulation of the same type, density and thickness as the original.
  5. Clean and thoroughly dry all electrical connections and compressor terminals. Any damaged wiring must also be replaced.
  6. After repairs have been completed, an operational safety check must be performed on the equipment.

The correct operation of all safety devices must be verified.

System Accessories

All system accessories, such as thermostats, air filters, indoor air quality equipment, electrical devices and the air distribution system, should be evaluated using the guidelines listed above.

Warranty

Flood damaged components are not covered by the Lennox limited warranty. New replacement parts carry a one-year limited warranty. Lennox further suggests making a thorough evaluation of the necessary repairs (labor and parts) in order to provide an accurate estimated the cost to the consumer. The estimate should also include an estimate for replacement equipment so the consumer can evaluate the options available and make the best decision for their situation and needs.

Lennox Announces Production End of Pulse Furnace Key Component Parts

In October, 2011 Lennox announced that several key components used in the Lennox Pulse product would no longer be available. This will affect the GSR14, G14, GSR21, G21, GSR21V and G21V product lines.

We have sold all of our available inventory of the 60J00 (60J0001) ignition control, 43G62 (43G6201) spark plug, and the 64K60 (64L6001) flame sensor used in these product lines.

If you have a GSR21, GSR21V, G21, or G21V series furnace in residential service that is less than 15 years old , and one of these key components fails, Lennox does have a program that will help you get a new furnace. Contact your local dealer if you feel that you feel that you qualify under this program.

There is really not any clairvoyants in the Heating and Air Conditioning Business!

It’s been an interesting week here at Cozy. Everyone is in a panic because their air conditioner is broke and we are working as fast as we can to help everyone get the parts they need.

One interesting issue that we have noticed this week is clairvoyant HVAC servicers. The hot weather brings them out. What is a clairvoyant HVAC servicer? A clairvoyant is a servicer that can diagnose your problem with no tools, or even opening the unit to take voltage readings and pressures.

We have had two people this week that hired A “professional” to diagnose their issue. In both cases, they were told that the fan motor was out on their condenser. These diagnosis’s were both made without the benefit of taking and voltage readings, or even opening the air conditioner to check anything. In both cases, owner’s purchased new fan motors based on what appears to be a clairvoyant diagnosis. Tge owner’s purchased new fan motors and installed them to find out that the problem was not the fan motor at all. The real issue was defective fan motor run capacitors. In both cases, the clairvoyant servicers had quoted the owners ridiculously high prices to replace the motor, so the owner’s chose to make the repair themselves. Evidently clairvoyant servicers are expensive too.

When it gets hot, many legitimate companies get a back log of work, and many owner’s will accept the first person they can get to show up and solve their issue. Be sure to use common sense when accepting a diagnosis from ANY company. Would you buy a new car engine from an automobile repair place that told you that you needed a new engine without even opening the hood of your car? Of course not!

Being miserably hot is no fun. Even under a stressful situation like trying to survive in 100 degree plus weather, you need to step back and take a good look at the situation before you accept a diagnosis at face value. And, of course, if your not somewhat skilled at doing the kind of work that needs to be done, let the professionals do it.
