Titan Pro vs Titan HD Capacitor: Which One Is Better?

Share This Guide

During regular maintenance, you find that your HVAC system capacitor needs a replacement. You head on to google and find out two good options: Titan Pro and Titan HD. But you are confused about picking the right one. 

So, which one to choose between Titan Pro vs Titan HD capacitor?

Compared to Titan HD, Titan Pro is more affordable with a small size and sturdy build quality. On the other hand, the Titan HD has superior technology with self-recovery and greater compatibility. It also has a 2.5 µF greater capacity than the Titan Pro. The dimensions also vary between the two capacitors.

That’s only a quick highlight. There’s more to come, just spare me a few minutes. We will take you through each aspect of choosing the best capacitor for your system.

Let’s begin.

Titan Pro vs Titan HD Capacitor: Quick Comparison 

Before we jump into the head-on comparison, let’s have a look at this quick comparison.

Titan Pro vs Titan HD Capacitor: Detailed Comparison 

As you’ve had a quick glimpse of Titan Pro vs Titan HD capacitors, here we have discussed the key differences in detail for your convenience.

Raw Materials:

Build material is an essential part of the capacitor build quality and lifetime. The titan HD is built with polypropylene whereas the Pro version has an aluminum build.

The polypropylene film technology enables the titan HD to self-restore itself in case of a breakdown. This adds to the durability and lifetime benefits.

The Aluminum build of the Titan Pro makes it sturdy and affordable. But the product’s durability does not deteriorate at this affordable rate.

Winner: Both capacitors have good build quality. However, the polypropylene film technology gives the titan HD an edge over the titan Pro. 

Hence, Titan HD is the winner of this segment.


The capacitor’s capacity directly affects the HVAC system’s cooling performance. The higher the µF rating, the more electricity it can store. 

Hence, a higher µF capacitor will enhance your system’s cooling capability.

The Titan Pro has a capacitance of 7.5 µF. On the other hand, The Titan HD variant has 10 µF. This gives the Titan HD an advantage of 2.5 µF.

The increased capacitance will help with the initial start of the cooling cycle. The cycle will start faster and more efficiently if your system has Titan HD capacitors.

And there is an advantage too; you can replace different rating AC capacitors. So, don’t worry if your system has a lower capacitance. You can replace it with a higher one.

Also, the Titan HD supports dual voltage like the Titan pro run capacitor 440/370. It supports both 440 and 370 Volt lines. 

Here are some of the available ones that I could find-

Titan Hd Round Motor Dual Run Capacitor, 55/5 MFDEnvironmentally-friendly oil substance, Rohs certificationsCheck Price

Winner: The extra 2.5 µF makes the Titan HD winner of this segment. It is also compatible with a lower capacitance system.

Overall Dimensions:

Overall height plays an important role in compatibility. You will want a capacitor that fits the gap in your HVAC system. Of course, a big capacitor will not fit in a small gap.

In this case, the Titan Pro is the smaller one. It has an overall height of 2 11/16 inches. On the other side, the Titan HD has an overall height of 3 ⅜ inches. 

Hence, the Titan Pro will fit in more tiny spaces than the Titan HD. Making it more suitable to narrow spaces and small systems.

Winner: The winner of this section is the Titan Pro capacitor. It has a smaller height making it easy to slip into narrow spaces.


The most important thing while choosing a capacitor is compatibility. A capacitor with greater compatibility will give you flexibility.

This is where the Titan HD shines. It has EIA-456-A, IEC 60252, UL, and cUL-certified compatibility. It meets the harsh EIA-456-A industry standard and delivers the best compatibility and performance.

On the other hand, the Titan Pro capacitor has IEC 60252-1:2001 certification. And also, it is compatible with most HVAC systems. 

Hence, you won’t need a compatibility guide like the coil and compressor guide.

Winner: The winner of the compatibility battle is the Titan HD. It is not only compatible with more systems but also meets the highest standards. 

This makes it an ideal choice for most applications.


Finally, the price bargain. You will always want a capacitor that is affordable yet reliable.

The Titan Pro is the cheaper of the two. It comes at a price of $9-13. But it has fewer features and cannot self-recover like the Titan HD. 

However, it can be a good choice as a second capacitor. Also, it can be a good option if you are on a budget.

Here are some Titan Pro capacitors to get an idea about the price-

On the other hand, the Titan HD comes in a price range of $25-30 per piece. This makes it a bit costly. 

However, it has far more capacitance and cutting-edge technologies. Hence, the high price is justified by the greater compatibility and technology.

If you do not have a budget problem, go for the Titan HD.

Winner: The winner of the segment is the Titan Pro, with an affordable price rate. However, the titan HD edges out the titan pro with better features and compatibility. 

Now, Which One to Go for? 

Both capacitors are good and offer a whopping 60,000-hour lifetime. Both have a good performance rating of 5.00 out of 5.00. 

However, the price, technology, and compatibility make the key difference. The Titan Pro is a cheap affordable option and better suited for budget users. 

But it lacks the polypropylene film technology of the titan HD, which helps in self-restoration. However, it is smaller in size, which fits narrow spaces.

On the other hand, the Titan HD has better technology but has a higher price. But it has the most rigorous IEC 60252-1:2001 certification and better compatibility. 

It also has a greater capacitance allowing better cooling performance for your HVAC system. 

Also, the Titan Pro HD capacitor warranty covers 5 years after the sale. That is a thing to note while buying a capacitor for your system.

If you want a good and affordable capacitor, pick the Titan Pro. If you want more technology, performance, and compatibility, choose Titan HD.

Frequently Asked Questions (FAQs)

Is It Good to Oversize Capacitors?

Oversizing the capacitors to a limit is good in practice. An oversize capacitor can increase power usage. Overheated windings in the motor will degrade its life whether the motor is oversized or undersized. Also, keep in mind that a smaller capacitor will result in decreased cooling performance.

Can a Capacitor Increase Fan Speed?

Yes, a capacitor can increase fan speed. When you increase the capacitance of a capacitor, the fan motor voltage increases. This results in a greater fan speed. Hence. You need a capacitor with greater capacitance if you want more fan speed. 


That will be all from our side on the titan pro vs titan HD capacitor debate. Both capacitors are good in their segments. 

Hopefully, this article will help you choose the best capacitor for your HVAC system.

See you soon.
