Gold Fin vs Blue Fin Condenser Coils in AC – Which works better?

Last Updated on 22 June, 2021 by Sourav Roy

When you’re out shopping for an AC, you might notice that most of the best ACs come with these fins. They’re supposed to help deal with corrosion. As corrosion is a significant issue when it comes to air conditioners, getting an AC with one of these fins becomes necessary. Otherwise, the condenser tubes are going to suffer and have to be repaired or replaced after a while. But that puts Gold Fin vs Blue Fin.

You have two choices, which works better? We’ll answer that question in this article and help you choose the one that fits your requirements the most.


Why use these fins?

The corrosion causes the AC function with much less efficiency. It can damage the coils of the AC and cause the refrigerant to leak out, reducing the performance of your AC.

Although corrosion has a much lesser chance of occurring in a copper coil, most AC makers go for aluminium coils instead as the copper is more expensive.

So, you end up with an AC that has copper tubes but with aluminium coils welded to them. As a result of using these two different metals, galvanic corrosion occurs.

Moreover, AC’s condenser tubes continuously come in contact with water. There are even more things that cause corrosion in the coils. For instance, near coastal areas, the coils are exposed to a high amount of acidic salts and humidity.

Manufacturers have come up with the Blue Fin and Gold Fin technologies to cover up this massive invulnerability. They use special anti-corrosive paints on the condenser tubes. Hence, the lifespan of the air conditioner increases dramatically. There are some things that set Gold Fins and Blue Fins apart from each other. We’ll talk about these things later on.

Gold Fins Vs Blue Fins – Which one is better for AC?

You must pick the right Fin for the air conditioner. The condenser functioning correctly is a must if you want your AC to cool appropriately. While these Fins might not seem like much or sometimes are barely mentioned in the product description, they play a vital role in the AC’s durability. Despite the fact though they work similarly, one is clearly the best for performance, unless you have other primary criteria for purchase.

Firstly, let’s talk about the fins themselves. With Blue Fin technology, the manufacturers put an anti-corrosive epoxy coating over the coils, enhancing the AC’s resistance against natural elements like moisture and humidity. The AC performs better even in harsh climates as a result.

Meanwhile, Gold Fins also work the same way, but the difference is that the coating for these fins is a golden hydrophilic one.

So, if you’re looking at things in terms of the initial budget, you can go for the ACs that use the Blue Fin technology. But, if you’re willing to spend some more, then you should go for the Gold Fins. In fact, the best air conditioners usually come with Gold Fin technology. It’s expensive, but it also gives the AC a more extended lifespan over its Blue counterpart, especially since the Gold Fins have higher rust resistance.

Besides, there’s a small boost in performance as well. The hydrophilic condensers accelerate the defrosting process, which improves the heating efficiency in Reverse Cycle models. Thus, you get a better heat exchange performance when you have an AC that has a condenser coated by layers of anti-corrosive Gold Fin protectants.

When it comes to Gold Fin vs Blue Fin, the Gold Fin technology wins in terms of practicality. It provides you with an extra edge against the corrosion caused by nature. In fact, it can make an AC run well even in coastal areas. If you want maximum efficiency and durability, we suggest going for Split ACs instead, some of which come with the Gold Fin technology.
