Welcome! My name is Mark and I am the inventor and founder of the DIYVAC. I came up with the unique device after many frustrating years servicing A/C systems. My background by trade is mechanical engineer/technician. I worked at luxury resorts servicing and maintaining many different systems that were highly important to the guest experience. These systems included A/C services to which I found a common theme: many simply had to have the drain line cleared so the unit would function properly. I simply needed a quick and efficient way to tackle this problem and after many months I came up with this unique PATENTED product that I knew everyone could use to SAVE them money on A/C maintenance.
