RESSAC We are a family-owned business, dedicated to the HVACR business since 1929. We pride ourselves on low prices and prompt service. We have earned a reputation as the lowest priced contractor serving the whole state of California. Our commercial clients wonder how we've been able to offer low pricing for so many years. The secret is old-fashioned efficiency.

We have always favored the stability of consistent customer satisfaction over the large but fleeting profits which are always possible in a construction business. We rarely take on debt, so we can gain business advantages during difficult recessions. We have operated out of the same corporate office in Glendale, California for over 45 years, so our capital costs other than trucks and technology are negligible.

Install New Equipment
Report

Repair
Report
Repair When your equipment breaks down, we're standing by to provide affordable and high-quality service. You can count on prompt response, because our employees are strategically placed throughout California so there's a technician near you. After 80 years in the business, we're experienced with all makes and models.
Maintenance
Report
Maintenance If you don't maintain your HVACR equipment, you could be paying up to 20% more for energy. And, your unit will age 5-10 years faster than a regularly maintained unit, possibly causing it to fail prematurely. Don't let your equipment deteriorate and cost you more money.

Love this company! Never installed controls before but they're willing to teach. Great team and work environment. Provided with all the tools needed to do the job! I would say the only con is being away from my wife but she's not complying because my checks make up for it

Jose is very professional. He explained everything and stayed until my freezer was fixed. He knows what he's doing! He is the best! God bless Jose!
