“They identified the problem and engineered a great redesign to fix some conditions that existed (we had a wooden plenum that leaked like a sieve). Now the system cools like a dream! From soup to nuts, they were awesome. Prompt, polite, professional. Other HVAC contractors are quick to point out a flaw in other companies and have their own hidden flaw, but Jim really cares about the reputation of this company. They’re good quality people!”                                    

     Dan M., Walnut Creek, Homeowner

“They were phenomenal! I wouldn’t hesitate to recommend them.”                            

      Anneta T. , Concord, Homeowner

“the company is very service oriented and has good integrity. When I called about a leak, they were right here to fix it. I’ve been happy with the work and would definitely recommend Contra Costa Climate Control.”   

      Anna O., Walnut Creek, Homeowner

“they were personable, approachable and attentive, and the quality of their workmanship was good. They walked through the house with me and wanted to be sure they put the vents in where I wanted. When I called, they answered my concerns.”                       
Rachel E., Pleasant Hill, Homeowner


“JIM’S A STRAIGHT SHOOTER, direct and to the point. He’s nonsensical; no BSing. He tells me: Here’s what is it. Here’s what we can do. Here’s what it will cost. When I pick up the phone, he’s there. And when I hang up the phone, it’s taken care of. He’s got my business because I trust him. They get the job done and right the first time. If something comes up and you bring it up to him, he makes it right. Rock solid, taking care of business.”

     Jeff E., Owner, Back Forty Texas BBQ, Pleasant Hill

“WE’VE USED CONTRA COSTA CLIMATE CONTROL for several years, and have received friendly, respon-sive service at reasonable rates. They’re easy to get a hold of and fast to respond to service calls—two important qualities for tenant satisfac-tion. They keep us apprised of repair costs, and give us options. We’re very pleased with the ser-vice we receive.”

     Kathe A., Anderson & Associates-Clayton Station Shopping Center, Clayton

“THEY CERTAINLY TAKE PRIDE in what they’re do-ing and have a very good work ethic. I’m very pleased with their excellent service, attention to detail, and the courtesy of how we’ve been treat-ed. The interaction with the staff is excellent. I’ve been impressed with the speed of going through the process (replacing facility-wide system — 11 units) and appreciate how concerned they were about getting the baffling and pressure adjusted across the entire system.”

     San Miguel Villas, Concord

“ON A SCALE OF 1 TO 10, I’d give them a 9. Nobody gets a 10 with me. They’ve replaced quite a few A/C systems for us and their work is excellent. At a comparable price. When I ask for the technician on the job to return my calls, they do! I have yet to find another company to do that.”
