I was shopping for a local company to install a new Ac unit for a 5 bedroom house I came across contra costa climate control. So I called them and asked for a quote includes everything. They emailed me the quote, which include the pricing and the unit and I looked up the unit and liked the review about it and asked them when they can do it so long story short they sent the best team as they were able to do the whole job in a timely manner. And I'm a very happy customer and recommend this local company for anyone.

Hello Everyone I been looking around for a local company to do maintenance for my HVAC system. My cousin recommended Contra Costa Climate Control for me.

I've worked for two different companies and luckily they both used Contra Costa Climate Control. With one company it was our computer server room, very high priority on keeping that cold and controlled, it was a very customized system that failed but these guys took it on and nailed it very quickly, with very little downtime. The technicians are very friendly and professional.
