Best Heating & Air Conditioning / HVAC In Walnut Creek

“Great service getting my Air conditioning up and running. Arrived within the expected window of time and was efficient in finding the problem.“

“Eco was recommended to me and after working with them in January 2026, I, too, can recommend this local business - competent, customer services oriented and most of all, superb teamwork end to end.

While the technology and the hardwares used are employed by many HVAC providers, the operation touches the attic to the crawl space and will take several consecutive days to complete, and the cost is not inexpensive, so organization, time management and customer care are critical to a desired outcome; and these are ECO's fortes.

From the initial call to the project end with a sign off from the city inspector, everyone including ECO's outside contractors worked with me; they thought of things that I did not even notice.

I could not have asked for a better construction/improvement outfit. I wish all my home projects can be done in such an effective and efficient way.“

“I had a great experience with Eco Energy Bay Area. They removed my old attic insulation, sealed all the entry gaps, and installed new insulation efficiently. Rami was friendly, professional, and explained every step of the process. The work was completed on time, and they left everything clean. Excellent service and quality workmanship. Highly recommend Eco Energy Bay Area and Rami!“
