Is Your Quick-ship Shut Down When Needed Most??
Approximately 70% of all Capital Coil’s orders over the last (3) months have involved some sort of quick-ship. Quick-ships are an integral part of Capital Coil’s overall business structure, and for that specific reason, unlike other manufacturers, Capital Coil & Air NEVER shuts down its quick-ships!!!

Top 10 Obscure Facts About HVAC Coils
HVAC Coils: the cost of copper is the main determinant of the cost of any coil as it takes up a massive percentage of any manufacturing costs. There are other materials involved, but they are minor in comparison when figuring out the overall cost. The cost of labor is relatively steady, so again this is why copper is THE determinant in coil pricing.

Large enough to service all of your commercial replacement coils, but small enough to care about what you think
What differentiates Capital Coil & Air from our competition is that we are big enough to handle all of your coil requirements, but still small enough to know who our customers are and what they need.

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.

Tips on Hand Designation & “Counter-flow”
Are your water coils right hand vs. left hand? Is it looking into the face of the coil or with the air hitting you in the back of the head? What exactly is counter-flow and why is it important? Are you completely confused by why right hand vs. left hand even exists?

Coils and Counter-flow: 5 Common Questions
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.

Steam Distributing (Non-Freeze) Coils: The Accidental Coils
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.
