What Our Clients Say

About Working with JJA, Inc.

“Today’s building designs have become more technically challenging – demanding sustainable mechanical, electrical, and plumbing systems, while meeting ever increasing building code requirements. For nearly 20 years, I have successfully relied upon JJA to listen to the client and design team – creating innovative solutions for today’s system designs.”

- Daniel L. Jeakins, Principal and Senior Vice President, HKS ARCHITECTS

“JJA provided our Client with a level of service above and beyond expectations. Their timeliness to resolving issues, ability to forecast problems before they occurred and commitment to the Client is what differentiates JJA from other firms. We worked closely with their Engineers to provide the right solution for the project and in the process, developed a lasting relationship with their firm”.

“JJA has proven to be the best commissioning agent I have ever used and you can feel confident the systems will be fully tested to work as designed when they are done. They write great scripts and you get a fully documented package to use a baseline for future maintenance and testing when the equipment is turned over to operations.”

- Neal Parker, Senior Regional Director, NOVA CORP
