Busting The Myth of The Freeze Proof Coil
Is it possible for a coil to be freeze proof? What you need to know.
Ever since Bob Cooney got the idea for a coil that could survive every freeze, no matter how fast or how cold, without rupturing, the Cooney Freeze Block technology has been the foundation of what we do here at Cooney Engineered Solutions. And with over 1,000 active installations and no failures, we are proud of what we’ve created.
If you are searching for a freeze proof coil, then you will always return empty-handed. Freeze proof coils do not exist. However, at Cooney Engineered Solutions, we have developed a coil that can freeze without rupturing. Through years of development, we stunned researchers in test after test as our Freeze Block coil refused to rupture. Now that the technology is on the market, we can offer you real Freeze Block technology instead of false freeze proof myths.
Why The Freeze Block Coil Is Better Than A Freeze Proof Coil

The goal of the Cooney Freeze Block coil is to allow the coil to freeze without damaging it. Bob’s key insight was that weather conditions and temperature fluctuations are often out of our control, and no matter how much antifreeze you pump into a system, odds are that it will eventually freeze, if the conditions are right. So instead of trying to prevent the HVAC coil from freezing in the first place, we came up with a way for the coil to comfortably freeze without rupturing, keeping the system intact and preventing any damage.
Here’s how it works. When a coil freezes, it freezes in one of two ways: From the center of the coil outward or from the outer edges of the coil in towards the center of the coil. When a coil freezes from the center outward, ice begins to build up within the center tubes, obstructing and freezing fluid as it flows outward. This leads to a scenario where ice moves from the middle to the return bends, where there is no room to expand. The bends swell with immense pressure, eventually bursting.
When a coil freezes from the outside in, the ice buildup begins at the ends of the tubes and moves towards the middle, eventually meeting ice approaching from the other side and rupturing the center of the tubes.
Our patented Freeze Block technology is capable of recognizing and responding to both of these scenarios simultaneously, meaning that no matter the situation, the Cooney Freeze Block coil will survive.
The Cooney Freeze Block coil is a one-of-a-kind piece of technology that has been tested all over the nation. We are proud to announce that our technology has protected thousands of coils over millions of hours in sub freezing temperatures without realizing any damage whatsoever. We have never had one rupture. That means you can count on your Cooney Freeze Block coil to do its job right, every time.
