McQueeney came on board in 1990 and mentored with Bill for 11 years before purchasing the business in 2001. Anne has done thousands of energy calculations for residential and commercial buildings throughout all 16 climate zones in the California. Anthony K.

Anthony has taken over the business and will continuing providing accurate and valuable T24 Services throughout California.

Here at Abbay Technical Services, our goal is to find the most cost-effective way to build while still complying with California's energy code. We work with architects, builders, contractors, developers, engineers and homeowners and provide the energy documentation that is needed for permit submittal. Communication is a key part of the compliance process, and we make sure to keep everybody on the same page throughout the project. Doing this gives the homeowner, builder, and other people involved, flexibility on building design while still following code requirements, and designing for future energy savings.
