Coastal Coating used an advanced HVAC coating process. The two products we use are CoilSafe^® coating compositions and ThermalBlock™ coating compositions.

Energy savings levels vary depending on your unit’s condition and age, but coil coating typically reduces energy consumption by 15-30% and extends the unit’s life by 50% or more.

Many traditional Epoxy and Polyurethane coatings do not improve efficiency and, because they are quite thick, (4-8 mils), actually impede heat exchange on the condenser coil and have no impact on run-time. Our CoilSafe^® coating compositions is one of a kind. It is 0.2 mils thick. That is over 40x thinner than traditional coil coatings and it is precisely this “innate thinness” that separates it from every other coating. This thinness allows it to wick into cracks and crevices on the coil and actually fill the gap between the fin shoulder and copper tubing that loosens with age and wear and is responsible for most efficiency loss. Our coil coating forms a covalent bond that becomes a permanent part of the coil and tube. When it hardens, it reconnects the fin to tube connection and can return the unit back close to its original factory efficiency, as measured by kilowatts per ton (KWT). Our exterior heat barrier coating can reduce run-times significantly, by reducing the exterior temperature of the unit to within a few degrees (5-10°F) of outside ambient temperature, even on very hot days.

There are only two things that impact your unit run-time:

1. Warm air returning to the unit from your building (load). We can’t help with that.
2. High interior temperatures inside your HVAC metal cabinet. We can positively impact that. Our ThermalBlock™ coating compositions exterior cabinet coating, will effectively block 95% of the sun’s solar heat, thus dramatically reducing the exterior temperature of your unit to within 5-10°F of the outside ambient temperature. This will definitely reduce your unit’s run time significantly.
3. Lower cooling utility bills, extended unit life, less repairs and lower maintenance costs are your results. “Run Less with Greater Efficiency!”

Yes, CoilSafe® and ThermalBlock™ have been through extensive, independent labratory testing.

Not at all! Partners that have been using our product and working with manufacturers and national/regional account reps from almost every factory for years have never had a warranty issue.

Energy studies conducted by AT&T, Florida Power & Light, Southern California Edison, TXU, as well as the EPA, indicate treated units significantly reduce the efficiency degradation curve on HVAC coils. It is further noted, units experiencing periodic cleaning maintenance will operate more efficiently than units not cleaned. However, it should also be noted that such cleaning gains are temporary and coils begin dirt buildup immediately after such cleaning, with most efficiency gains being lost in the 30-60 days following cleaning.

This coil coating technology is only available through our supplier (CoatZone) and it’s trusted vendors (that’s us!)

Your Return on Investment depends on a variety of factors, however, the typical ROI is under 24 months and it’s common for our partners to see ROI in 9-18 months!

Because of the glass-like surface that is created by our coil coating, mold, mildew, bacteria, dirt and other environmental debris will not adhere to the surface and definitely will not get impacted into the coil as with a non-coated coil. All such debris are repelled and rejected by the glass-like coated coil surface and will require only a mild washing with an ordinary garden hose (no high pressure needed) to completely remove any surface dirt. An annual cleaning of this nature should be all that is needed to maintain a clean coil.

Our technology is designed for very long life and harsh environments. Both coatings are known for performing for many years in the harshest environments and our goal is to provide you with a “one-and-done” solution. Typically we expect both coatings to last the entire useful life of a unit.

Here’s why: our coil coating is an inorganic coating that chemically bonds, at the atomic level, to the bare, non-ferrous aluminum coils and copper tubing. When properly applied, this covalent bond actually becomes a part of the metal substrate.

In contrast, phenolic organic paints adhere by “London Force” adhesion, which means they cling to whatever surface anchor pattern is available. They can chip, peel, and dynamic energy forces, such as expansion, contraction, and vibration can cause organic coatings to prematurely lose their adhesion. The covalent bond formed with the CoilSafe^® coating compositions is not impacted by these forces. A typical rule-of-thumb is, whatever life the unit experiences uncoated, depending on existing environmental exposures, the San Diego Coastal Coating company treatment should double the useful life of that unit.

“Run Less with Greater Efficiency!”

Remember, doing nothing does not reduce your cost. Cooling and heating costs are projected to increase by 40% or more over the next five years. Maintenance costs will not be going down either. So your cost of doing nothing simply guarantees higher energy costs, higher repair costs and higher capital expense replacement costs.

Net Present Value (NPV) – ASHRAE has determined average HVAC commercial unit replacement costs at $2,000/Ton. San Diego Coastal Coating can add many years to your unit’s useful life. Consider the NPV savings on deferring replacement of a $100,000 unit for the next 5-7 years.

Just analyzing the Net Present Value (NPV) of being able to defer your current capital expense for new replacement units at $2,000/Ton for those years, may actually save you more than your actual energy savings, and it goes directly to your bottom line that year.
