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 Should Steam Coils Be Designed??

Steam Coils require a real expertise to design & build. We at Capital Coil have a long history in solving coil problems and building steam coils so that they work correctly the first time.
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 […]
Guidelines For Air Velocities

Step # 1 in determining the size and performance of a coil is dependent upon understanding face velocities of air across the coil. Whether you use CCA’s coil selection program to help size the coil, or you are replacing an existing coil; the height, length and resulting velocity determine everything.
Steam Distributing Coils (Non-Freeze)

Were you aware that Steam Distributing coils or “Non-Freeze” steam coils were essentially discovered by accident? At the inception of the HVAC industry, steam coils were originally designed to be shorter in length because there was not a good way to evacuate condensate. In an effort to make steam coils longer in length, the concept of a steam coil containing a tube within a tube was invented.
Top 5 Reasons Commercial HVAC Coils Prematurely Fail

Capital Coil & Air has come across virtually every scenario over the years in which a commercial HVAC coil had to be prematurely replaced, and we have since created an easy guide targeting the main reasons HVAC Coils prematurely fail.
Different Types of Steam Coils

There are two types of steam coils: standard steam coil, which is used in most reheat applications, and steam distributing coils, which are used in applications where the entering air temperature is below 40 F degrees.
How to Make Sense of Heating Coils

Of all the types of HVAC coils available, heating coils are probably the easiest to select and understand. Capital Coil has listed the three most common types of heating coils that you are likely to come across.
Frozen Steam Coils: How Do You Prevent This?

Freezes generally happen in older systems, however if your new system is not maintained properly or correctly installed, your steam coil can and will freeze.
What Is Meant By A “Bank” Of Chilled Water Coils

For those that work with HVAC installations on a regular basis, you have run across the problem of needing to install new chilled water coils in very tight, confined areas. To avoid these issues, simply break down the single, larger coil into smaller coils. When piped together, those smaller coils are stacked into “banks” of coils in the system. If installed correctly, this “bank” should have the same performance as the larger, single coil.
