**SITE BITE: Correcting Improperly Installed Chilled Water Coils**
On-site with Stephen Barzelatto, Vice President of Nationwide Coils, as he identifies and corrects a common mistake in the installation of chilled water coils.
---
Recently, I was on-site at one of the local hospitals we service in Florida to measure six chilled water coils for replacement. As I reviewed the existing units, I was surprised to find that all six had been installed as left-hand coils—despite the fact that three of them should have been right-hand coils.
This error is more than just a technical oversight; it can significantly impact the performance of the HVAC system. In a hospital setting, where indoor air quality and temperature control are critical, such mistakes can have serious consequences.
Incorrect coil orientation affects airflow and counterflow, reducing the unit’s efficiency. In this case, the misalignment led to a 2-3% loss in efficiency per row of the coil. With a six-row system, that adds up to a potential 15% efficiency loss. Over time, this results in higher energy costs, reduced cooling capacity, and overall poor system performance.
The good news is that I caught the issue early during the measurement process and ensured the correct coils were ordered and installed. This simple fix made a big difference in restoring the system to its optimal performance.
At Nationwide Coils, we understand the importance of getting the right coil every time. Our team of experts ensures that each replacement is accurate, reliable, and tailored to your specific needs. Whether you're managing a commercial building or a healthcare facility, choosing a trusted coil provider like us helps maintain peak HVAC performance and long-term savings.
