Heating & Air Conditioning / HVAC near Walnut Creek

“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.“

“Here’s a review you could post:

We had a great experience with Big Air Heating and Air Conditioning this week. The technician flushed our water heater, replaced the anode rod, and installed an expansion tank. From start to finish, the service was professional, friendly, and informative.

What stood out most was how willing they were to explain what they were doing and educate us on the condition of our water heater and the purpose of the repairs. They took the time to answer our questions without making us feel rushed and helped us better understand how to maintain the system going forward.

The work was completed efficiently, everything was left clean, and the entire experience felt honest and trustworthy. It’s not often you find a company that combines technical expertise with such great customer service. We would definitely recommend Big Air Heating and Air Conditioning to anyone looking for reliable, knowledgeable, and friendly service.“

“11 out of 10 stars! Green Air delivered on every level—comfort, sustainability, and pure happiness.

We were struggling with a broken Dyvak system that left our home feeling stale, unevenly heated, and just plain uncomfortable. Then came Nick, Jayman, and the amazing Green Air team. They were fast, knowledgeable, and genuinely fun to work with. Every visit was filled with laughter and expertise.

They installed a Samsung HVAC system and solar panels, and the transformation was immediate. The air feels clean and fresh, the temperature is perfectly balanced, and everything runs on green energy. And who knew solar panels could be beautiful? Ours are sleek, stylish, and surprisingly elegant.

Who knew that upgrading your HVAC and going solar could bring so much joy? We didn’t just fix a system—we elevated our whole lifestyle. Can’t recommend Green Air enough!“

“Chris and his guys are great. Very professional and fair. We have a new heater now and couldn’t be happier.“

“I had tried several out of the box HVAC companies before a friend told me about Absolute Air. The other companies kept trying to sell me a new system I didn't need at the time. Absolute Air came and did a thorough analysis and told me all of my options to get my ducts repaired. From Carol on the phone, to Cole in the field, to Josue and all the techs, every staff member is courteous and takes their time to explain possible options and what to costs to expect. I love that they are local to Martinez and a family owned business. I will ONLY hire Absolute Air to repair and maintain my HVAC system. When the time comes to get a new one, I already know who I am going to call!“

Andy's expertise in replacing my HVAC system from gas to electric was truly impressive. He walked me through every step of the process, ensuring I understood everything that was happening. His pricing was incredibly fair and affordable, which was a huge relief. Beyond the installation, Andy went above and beyond. He conducted a thorough check of my home to ensure everything was working optimally and even offered to continuously monitor the HVAC capabilities to guarantee the best service. Andy is not only a skilled technician but also a genuinely friendly and easy-going guy. I highly recommend his services to anyone in need of HVAC work!“

Thank you. aPeirce McKee, your $1299 customer“

“My AC went out a few months ago during the heat wave. The original company that installed the AC 3 years ago didn't want to take responsibility of fixing it. After a couple of months of trying to find someone to fix our AC, a friend recommended MechPros. I emailed MechPros of what has happened to the AC, Kelly was fast to respond. She got Paul to call me and I gave him details of why the AC stopped running. We texted to try to get the unit fixed. They ordered the part, squeezed us into their very busy schedule and their technicians came and got our AC up and running.
That's a great company!!
I would recommend MechPros to anyone that needs their AC repaired.
Thank you MechPros Team!!! ?“

I called them to come a year later and change the filters and they scheduled an appointment right away. Their technicians are all superb, very well trained and a pleasure to work with. Highly recommend these folks.“

“Excellent service and highly recommend East Bay Heating & Cooling!! We had issues with our heating system and East Bay fixed it right away.
