“It has been a pleasure working with Joe Bowman and A/C Technical Services from the award of the Chesapeake Energy Field Office Project. The vast number of changes and additions to the project throughout the last year were accomplished by using well versed subcontractors such as A/C Technical Services. They were able to incorporate these changes and adapt to schedule revisions while maintaining a high quality of workmanship. I would recommend using A/C Technical Services, LLC. as a mechanical contractor and look forward to working with them in the future.”

Design Build

A/C Technical Services, LLC has faced some of the most complex challenges brought about by the system demands in Texas towards offering facilities with a wide reach and in keeping our customers comfortable. The biggest challenge it faces is in the design and the building of the right HVAC systems to meet the needs of customers in San Antonio, Hondo, Castroville and all over the area. The design-build attitude ends up saving valuable money and time for the customers.

A budget can be determined quite early in the process of designing so that costly overruns are avoided and there is no need later on to re-engineer after the bid is finalized.

Our team coordinates with architects, general contractors and customers to identify the HVAC needs and anticipates changes in the future. Heating, Ventilating & Air Conditioning systems eat up almost forty per cent of the energy that is used in the buildings in the U.S. Using high-performance equipment for the HVAC systems will offer considerable savings in energy cost and emissions. Designing for the whole building with an extended concept of a comfort zone can give savings of up to forty percent.
