It IS Easy being Green! Control your building and reduce fuel costs with an OAS Heat Computer.

OAS believes you have choices…you can either let your buildings control you or you can take control of your buildings—clearly, we believe that you must be in control…and we are in business to make this happen for you.

Our roots run deep in the energy control business and we have a track record to prove it with thousands of Heat Computers already installed - this enduring focus on green science and engineering continues to drive the development of our powerful products and services.

Making it easy!

Our mission and our passion has led us to partner with Verizon Wireless so that we can offer you high-speed internet services to operate your Heat Computer at a discounted bundled rate…our web-based platform linked to the Verizon Wireless network is a match made for unsurpassed cost savings.


With the leadership of OAS President Edward Winiarski, we are expanding to a national and international marketplace, where the need to reduce oil consumption and increase efficiency is fundamental.
