7 Years & Counting

What do you know about your heating & air?

If you’re anything like me, the only thing I used to know about my air conditioner was to turn it on or off.

In 2010, I started working for Controlled Release Technologies. From that moment on, everything I had ever thought about HVAC has changed (for the better).

Fast forward 7 years of being with CRT and a part of the HVAC Industry!

Here are just a few of the many things I have learned.

  • How vast the HVAC industry is. 
  • How the system works.
  • Why it is important to maintain the HVAC unit.
  • How to protect investments.
  • How our products help with preventative maintenance.

Thankfully, I have had the honor of  working among the most knowledgable people in the industry & every single day I get to learn about HVAC and meet new individuals. By far, my favorite thing about working for Controlled Release these last 7 years has been creating life-long relationships with my “friends” (not clients but friends). I look forward to the years to come!


Instead of Replacing – Resurface & Recycle

You’ve seen them. Drain pans covered in rust, holes in the bottom, leaking water all over the area. But it can be costly to replace the entire drain pan, or worse, the entire unit. Instead of replacing, we developed a way to resurface and recycle. Keep your drain pan, and make it fresh as new. This family of products will beautifully resurface a drain pan and its surroundings, without costing you an arm and a leg.



We cannot wait to hear from you! Call us at 800-766-9057 or email us at sales@cleanac.com to get information on our resurfacing products V570 & Pancrete.
