There are two different types of coils available in any air conditioning or refrigeration unit: the evaporator coil and the condenser coil.
Out of these two, the condenser coil is exposed to the atmosphere, and thus prone to the harmful effect of corrosion.
Gold fin and blue fin coatings address this issue and protect the coils from corrosion. Although both serve the same purpose, they still have some differences.
In this article, let’s learn more about the differences between Gold Fin vs Blue Fin in AC.
But before that, it’s wise to learn what fins are in AC.
What Is Fin In AC?
Fins are thin metal strips that transfer heat from one coil to another in the condenser and evaporator.
Thousands of fins could run along the periphery of the coils. Damaged fins can drastically affect the performance of an AC unit or a refrigeration unit.
Goldfin or bluefin does not mean that only fins are coated. Condenser pipes are also coated with fins. Evaporator coils do not need any coating as these are not directly exposed to the atmosphere.
What Is Blue Fin Technology In AC?
Metals are prone to corrosion when exposed to the atmosphere. Condenser coils are ideally made of either copper or aluminum, with copper being the more expensive and better heat-conductive.
However, bare metals attract a lot of dust, water droplet deposition, and acidic salts, especially in coastal areas.
Although copper does not corrode easily over time, contaminants can still damage the copper tube, and you will end up paying a huge repair bill.
This is where the bluefin technology comes into play. It is an epoxy coating on top of the coils and fins.
The coating prevents the harmful effects of acidic salt and other contaminants. The low surface tension prevents the deposition of water droplets on the tube.
So, in summary, bluefin technology prevents corrosion in the condenser tube and thus enhances the life of the AC.
What Is Gold Fin Technology?
Gold Fin Technology does the same thing as Blue Fin Technology. However, its only other benefit is that it enhances the AC’s heat transfer performance.
It uses a revolutionary golden hydrophilic coating over the Condenser coils, preventing them from water, acidic salts, and other contaminants. The coating is also synthesized from titanium oxide, which aids in better heat transfer.
Conclusion: Blue Fin AC Vs Gold Fin AC
Both are excellent technologies for protecting the condenser pipe from corrosion. Goldfin does not have a huge advantage over bluefin, except for the better heat conductivity.
If the price difference between Gold Fin and Blue Fin AC is huge, I would suggest going ahead with Blue Fin AC only.

What Are The Differences Between Gold Fin And Blue Fin In AC?
Both gold fin and blue fin technology are meant to protect the condenser coils from the harmful effects of the atmosphere.
However, the gold fin goes one step further and improves the thermal conductivity of the condenser coil, which the blue fin does not.
