HVAC Customer Reviews

My son has used CCCC for maintenance and repairs on his system for years. Always spoke highly of them and in a couple cases their integrity and honesty really showed how good they are. I used them for the first time for a maintenance service and everything was great. Zach showed up on time and gave the system a thorough oversight. He was clean as he worked, courteous and very personable. Great experience. I’ll be using them again and suggest others give them a try as well. Read Less

I would give more stars if I could. Contra Costa Climate Control is the best. Having worked with many others over the years, I can’t recommend them highly enough. Both Javier and Brandon have done maintenance on my HVAC system. They’re friendly, extremely personable, on time and always call when they’re on their way. Their pricing is reasonable with NO UP-SELLING. Happy customer here! Read Less

Brandon Lopez at Contra Costa Climate Control ROCKS! He arrived promptly and did a through inspection. Brandon found and fixed the problem and also fixed a gas leak and cleaned our filter. He kept me updated through the process and was knowledgeable and polite. I would not hesitate to call on him again! Thank you so much, Brandon! Warmly, Darien Rule Read Less
