The RESSAC Blog is Back for Our 90th Anniversary.

RESSAC's 90th Anniversary Logo.

We’re excited to announce the relaunch our RESSAC blog for 2019. This is a big year for us, as we’re commemorating our 90th consecutive year serving California. It’s been a long road from the small shop in LA to the statewide business we are now. And we’re delighted to be standing here today to share this moment with all our customers. Through three generations of family ownership, we’ve seen the service industry evolve, and with every change we’ve striven to adapt. With focused technician training and updated office technology, we are better prepared than ever to keep your stores comfortable this coming year.

Every month this year we’ll be posting new articles about the HVACR industry, with a focus on customer impact, comfort, and productivity. In addition, we’re live again on Facebook and LinkedIn. Our new Instagram account posts weekly photos from our technicians in the field. Stop by any time to chat with our team and learn something new about HVACR.

From all of us at RESSAC, thank you. Without the opportunities provided by our customers, we wouldn’t be celebrating this milestone with you now. Wishing all of you a cool, comfortable and productive 2019!
