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 itself. New is always more efficient than old.

2. If you’re ever in doubt about a dimension, smaller is always better than bigger!!! You can always “safe off” around any coil as long as you can fit it in the space. If a coil is too big, it makes a really ugly coffee table in your shop. Too big is the enemy of measuring coils.

3. The fin height (FH) and fin length (FL) are not the determining factors in measuring a coil. The overall casing (CH & CL) dimensions are the most important, and you work backwards to determine fin dimensions.

4. The casing depth (CD) of any coil is the total casing depth in the direction of airflow. The height is the number of tubes high in any row. Depth is a function of rows deep and height is a function of tubes in a row.

5. Overall length (OAL) is not the fin length and it’s not the casing length. It is the length from the return bends to include the headers that are inside the unit. Again, it is necessary to work backwards to get the other dimensions once you know this critical dimension.

6. Circuiting is the number of tubes connected to the supply header. Generally, you just want to count the number of tubes connected to the header and that will tell you whether it’s full, half, or even a double circuit. It does not matter how the return bends are configured. Your goal is to count the number of supply tubes and all performance is based on that.
