About Us

We are a third generation family-owned business focusing on the service of light commercial mechanical systems. Our specialty is low-rise office parks, mall retail, and big box retail sites.

At RESSAC, we have earned a reputation as one of the lowest priced self-performing commerical contractors serving the whole state of California. Our commercial clients wonder how we’ve been able to offer such low pricing while maintaining a quality that exceeds most other contractors. The secret is great employees and a laser focus on operational efficiency.

Great Employees Provide Quality Work

When it comes to experience, our company has a deep bench. Our staff has over 500 years of HVACR experience working for our company alone. We compensate our employees well and invest in their training and development. Our talented NATE certified technicians are strategically located throughout the state of California. They are not subcontractors, they are employees on our payroll. They know their territories well and have been on thousands of roofs. If your company operates out of regional malls or local strip centers then they have likely already been on your roof!

Efficient Operations Keeps Our Prices Low

RESSAC believes in continuous improvement of business processes. We are on the leading edge of cloud based technologies to manage operations and to communicate work. Every technician is outfitted with an iPhone and iPad. All work performed in the field is documented digitally and uploaded to cloud servers in real time for office and customer access. Utilizing fleet management partners and the same corporate office for over 60 years RESSAC also keeps its capital structure lean. These tactics and more allow us to constantly drive costs lower without compromising quality.
