When is it Time to Replace a Coil?

Replacing heat exchanger coils has been taking place since the beginning of the HVAC and processing and cooling era.

It’s now close to 90 years since the first finned tube heat exchangers appeared on the market in the early 1900’s. The coil has undergone drastic changes over the years - from spiral wound type through the plate fin coils that currently dominate the market. Throughout each decade, the coil has had a timeframe wherein the materials finally wear out and the coil needs to be replaced. There have also been many reasons why a coil fails prematurely and needs to be replaced.  You could equate coils to the same analogy as human beings – some die of natural causes and some die prematurely due to disease. 

Our experience over decades in the coil replacement market has provided us with some important information – only 10% of all installed coils are being replaced because they are “worn out”.  There are many reasons why heating and cooling coils are being replaced every day.  In many cases, entire systems are replaced because of better technology or efficiency versus just replacing the coil.  For those who have been around a while, you will remember the energy efficiency eras of the 70’s and 80’s, as well as the environmental issues with refrigerants over the last 20 years.
