During the HVAC sales process, questions occur from the purchaser concerning obtaining a clear understanding of the value of the AE Dual Defense System relating to the features and benefits that will be realized. Here is a compilation of the most often asked questions and answers that have been experienced by Certified Installers and Sales Agents of the AE Dual Defense:

AE DUAL DEFENSE Frequently Asked Questions

How long will the treatment last?

AE Dual Defense chemically bonds, at the atomic level, to the bare non-ferrous aluminum and copper. When properly installed, this covalent bond is difficult to break. In contrast, organic paints adhere strictly by ‘London Force Adhesion’, which means these coatings cling to whatever surface anchor pattern is available. Dynamic energy forces, such as expansion and contraction and vibration can cause organic coatings to prematurely lose adhesion, whereas the AE Dual Defense bond is not impacted by these forces. A typical rule-of-thumb is that whatever life a unit experiences uncoated, depending on environmental exposures, the AE Dual Defense treatment should double that life.

How thick is the AE Dual Defense dry film?

AE Dual Defense films will cure to between 6 and 8 microns. One micron is 1/25th of a mil; one mil is 1/1000th of an inch. Hence, the dry film thickness of AE Dual Defense HVAC Protective Treatments would be approximately 1/3 of a mil. Typical organic paint films will cure to between 3 and 4 mils DFT.

Will the AE Dual Defense DFT interfere with laminar air flow?

Third Party test results indicate that the laminar air flow across the coil/fin surface is actually improved (see Auburn University – Brennison Test).

Will the AE Dual Defense film interfere with heat transfer efficiency?

No! Third Party test results indicate that no measurable change occurs when comparing bare and treated non-ferrous metal (see EPA Energy Savings Report). Organic protective coatings cannot make or substantiate this important claim.

Can AE Dual Defense be used as a topcoating over existing organic paints?

Yes, however, if the existing paint film loses adhesion, the AE Dual Defense treatment provides no particular protection.

Who uses AE Dual Defense treatments?

Some of the end-users include the US Navy, US Coast Guard, US Air Force, US Army, Lowe’s, Home Depot, Office Depot, Walgreen’s, AT & T, numerous Public Schools & Universities, Bass Pro Shops, numerous other private and public entities.

What testing has been run?

Third Party Testing Labs have conducted the AE Dual Defense HVAC protective treatments have performed in excess of 4,000 hours. See Technical Product Data Sheet for additional information.

Can AE Dual Defense be installed to existing field units?

Yes! AE Dual Defense treatment can provide benefits to existing units, however, the condition of the unit, pre-installation, will determine the degree of effectiveness.

How is the impact on energy savings determined?

Energy studies by the EPA indicate that treated units significantly extend the energy consumption curve deterioration of HVAC units. It is further noted that units experiencing periodic cleaning maintenance will operate more efficiently than units not subject to periodic cleaning regimens.

Can I receive energy credits if I coat my HVAC unit?

Each State and power company have different criteria for the receipt of energy credits. Therefore, it is prudent to check with these agencies in your area.

Will your cleaning & conditioning products deteriorate my roof membrane?


Is AE Dual Defense resistant to UV exposure?

Yes! Being an inorganic treatment, the cured film is inert and extremely UV resistant.

How is AE Dual Defense installed?

AE Dual Defense protective treatments are applied by company trained and certified installers, only. These certified installers can apply this protective treatment in the field.

What parts of the HVAC unit can receive and benefit from AE Dual Defense?

Aluminum, copper & stainless coils, tubes, headers, fans, blowers, frames, factory coated cabinetry, fan guards, supports, etc; Electronic parts should be masked to protect from cleaning and coating regimens.

Will the installation of AE Dual Defense on my fan blades cause a balance problem?

No! The installation of AE Dual Defense results in a dry film thickness of between 6 and 8 microns (1/3 mil). This ultra-thin protective film will not cause fan blades to go off balance.

Is there any benefit to treating HVAC cabinets?

AE Dual Defense process specifically includes the coating of a discrete type of ceramic coating. This coating is critical to achieving the overall energy savings of the system. Typical OEM powder coatings can fade and oxidize in short periods of time. Not only is faded paint unsightly, but as paint oxidizes it loses film integrity, thus, potentially exposing the underlying substrates to the elements. If the HVAC unit is in a salt spray or other aggressive environment, it is very advantageous to place the AE Dual Defense clear treatment over the factory powder coating.

Will hot water negatively impact my coils?

No! AE Dual Defense films can resist continuous heat up to 2000 degrees Fahrenheit and intermittent heat to about 6000 degrees Fahrenheit.

Is AE Dual Defense resistant to chemical attack?

Yes! The cured AE Dual Defense film is highly resistant to a wide range of acid, basic, gas, water and solvent exposures.
