Copper coils in some a/c units are corroding and the HVAC industry is on alert.

In his 35 years in the HVAC industry, David Mathews, owner of CCAC Inc., an air conditioning company in Texas, has had experience with myriads of HVAC applications and the situational obstacles that arise from working with heating and cooling equipment. One such obstacle gave birth to the AC-Enhancer®.

If you wholeheartedly accept that global warming exists and that we humans caused it, I am curious as to whether you ever considered that Al Gore lied and science backed him.

Next time you hear someone say, “HVACR contractors aren’t tech savvy,” send them to www.blackallmech.com. Not only do they incorporate video into their Website, but they also communicate with some of their customers via video.

“Welcome to Washington; we’ve changed the weather just for you.” Those were the words of notable journalist and publisher Llewellyn King as he addressed the group of manufacturer members attending the Air Conditioning, Heating, and Refrigeration Institute’s (AHRI’s) Public Policy Symposium.
