Top 10 Tips For Measuring HVAC Coils
1. When measuring HVAC coils, performance has very little to do with accurately measuring for replacement coils. Fitting the coil in the existing space with the least amount of labor has everything to do with measuring a coil. If you duplicate the coil in almost every respect, the performance will match and take care of […]
How Data Centers Are Reshaping Replacement HVAC Coil Lead Times
Data Centers Are Reshaping the HVAC Supply Chain If you’ve recently tried to purchase a replacement HVAC coils, you’ve likely noticed longer lead times, fewer quick-ship options, and rising costs. The primary reason? The explosive growth of data centers. Driven by cloud computing, AI, and digital infrastructure expansion, data centers are consuming massive amounts of […]
DX Coil Replacement for Harsh, High-Humidity Mushroom Farm Environments
Kennett Square, PA is widely known as the mushroom capital of the world. It is also located just a short drive from Capital Coil & Air’s sales office in West Chester, PA. Because of that proximity, we regularly receive requests from local mushroom farms to visit their facilities and measure failing DX coils for replacement. […]
Coils and Counter-Flow: 5 Quick HVAC Questions Answered
The first thing to remember about coils and counter-flow is that chilled water coils are always built to be piped in counter-flow. This means that the air flows in the opposite direction as the water. For example, with counter-flow, the air flows through rows 1-8, while the water runs through rows 8-1. Water always travels through the coil in the opposite direction of the air; hence the term “counter-flow.” Direct Expansion Coils (Evaporator Coils) are also piped in the same manner.
Condenser Coil Failing? Here’s Why
Very rarely do condenser coils ever freeze so the first thing you’re going to want to know is if your coil died of corrosion, old age, or possibly vibration. Old age is obviously preferable because with a few easy dimensions, we’ll have enough to price up your duplicate coil.

Why Are HVAC Coils Made with Copper Tubes and Aluminum Fins?
It’s no coincidence that HVAC coils predominantly use copper tubes and aluminum fins. Copper is known to have exceptional heat transfer properties, while aluminum, although effective, does not match copper’s performance. When it comes to HVAC coils, the primary goal is either cooling or heating, which means heat transfer is a top priority. Right behind […]
Replacing Carrier Chilled Water Coils
For HVAC professionals, replacing Carrier chilled water coils is a task that demands precision. One miscalculation in dimensions, connection types, or circuit configurations can turn a straightforward replacement into a significant challenge, leading to delays and complications like compromised airflow or customer callbacks. Why Precision Is Critical Carrier chilled water coils are engineered with extremely […]
Why Cooling Coils Need to Be Replaced
In theory, properly engineered and maintained cooling coils should deliver 20+ years of service life. In practice, most coils are replaced prematurely. The root causes are typically operational neglect, environmental exposure, improper application, or design limitations. Below are the three primary drivers of early replacement, along with technical context. 1. Increased Air Resistance from Coil […]
Looking For A Trane Replacement Coil
If you need Trane replacement coil within a Trane system, but aren’t sure about the dimensions or decoding the model #, send this to Capital Coil & Air for pricing. On most Trane AHU’s, the AHU model #, as well as the coil or “part #”, is listed as “Service Model No Coil”. If you […]
