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 […]
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. […]
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.
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.
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 […]
Top 10 Chilled Water Coil Facts
Every Chilled Water Coil selection is about balance. Your coil selection balances the rows/fins versus the cost of the coil pressure drops/performance. 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 […]
10 Things To Know About Chilled Water Coils
1. Hot or chilled water coils are still water coils. There is really no difference between hot water coils and a chilled water coils in construction. Hot water coils are usually 1 or 2 rows and chilled water coils are usually 3 to 12 rows deep. 2. The vast majority of chilled water coils are […]

What Does “Splitting” DX (Evaporator) Coils Mean
Cooling Coils & Moisture Carryover
Many people do not think that moisture carryover is a problem…until you have moisture running down ductwork or spewing all over the inside of an air handler.
