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 […]
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

Chilled Water Coils – Circuiting Made Easy
Circuiting chilled water coils is really a balancing act of tube velocity and pressure drop. In other words, think of a coil as a matrix. Each coil has a specific number of rows, and a specific number of tubes within each row.
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.

Trying to cut corners on your initial selection may save you money upfront, but you will inevitably pay it back down the line through added energy costs. This is a truism for every manufactured […]
OEM Replacement Coils: Repair or Replace
The real reason why OEM HVAC coils need to be replaced rather than repaired is due to energy costs. If your coil is not operating near desired levels, you’ll need to increase the energy to make it work at its peak performance.
