Best Heating & Air Conditioning / HVAC In Pleasanton

“Nick F was amazing and did an outstanding job servicing my AC system for the summer season. From start to finish, Nick was professional, knowledgeable, and thorough. He walked me through everything he was doing, answered all of my questions with confidence, and clearly knew the technical side of the system inside and out. The service was completed efficiently and without any hassle, and you could tell Nick genuinely takes pride in his work. It’s rare to find someone who combines strong technical expertise with such great customer service, and Nick absolutely delivered on both fronts. I couldn’t be more satisfied with the experience and would highly recommend him to anyone in need of AC service. In“

“Cody and the installation team were amazing and extremely efficient. The whole installation took less than an hour and I felt in the loop the whole time. My biggest complaint was a clerical error with the incorrect address. Numerous discussion were had around this and on the day of installation, it was still wrong.“

“Ethan provided professional service and recommendations. He really knew his job and it was a pleasure having him working in our home.“

“David G. was great to work with. He was very efficient and honest. I called on Art of Comfort for a second opinion after another vendor quoted very high estimates to repair two AC units that didn't seem quite right. David had a very different perspective, which made a lot more sense, and he simply provided his expert advice without applying any aggressive sales tactics. I really appreciated his approach and look forward to continuing to work with him.“

“Thank you Sabino! We have had him replace parts on the AC this past summer, and the heater a week ago. JJ ordered the parts needed and once they came in, Sabino had them installed in a couple of hours.“

“Bret and his team were responsive, knowledgeable, and quickly resolved our heating issue for our tenant. Thank you to these professionals!“

“Out of the 10 to 20 people who have worked on my house over the years, Jay is the best contractor. He is very personable and does a great job.“

“Rivers plumbing is great. Honest, knowledgeable and affordable, they have provided great service for my family over the years. Rivers is the best in the Tri-Valley area.“

“I was surprised by the dramatic difference after Pleasanton Air Duct Repair Services cleaned our air ducts. The air feels cleaner, and our HVAC system is more efficient. The employees were on time, respectful, and highly skilled. The results show how carefully they worked.“

“Dave Gray (Owner) has a "No nonsense" approach serving this industry that has been effective nearly 5 decades. I myself, as a competitor, also being in the business for nearly 30 years holding (3) California state contractor classification, New Mechanical Services has my utmost admiration for its longevity.“

“Had a really good experience with Contra Costa Heating & Air Conditioning. We went through their Costco partnership and had a new HVAC system installed in late Oct / Nov 2025. The install was smooth end to end, and the crew was professional, punctual, and easy to work with.

They also removed an old thermostat and patched the drywall. The first patch wasn’t great, but I called them back and they sent someone out who fixed it properly. The wall looks good as new now.

After the install, I noticed some uneven temperatures between zones. They came out, checked everything, and confirmed the thermostats were reading accurately. They even offered to replace them. I ended up resolving it myself by adjusting the system’s circulation settings, which improved airflow and evened things out.

On pricing, their initial quote came in higher than a few other vendors. That’s mainly because they use higher quality equipment and components. When I asked other vendors to match the same setup, the pricing ended up pretty close anyway. Contra Costa also offers strong guarantees on workmanship and parts, which gave me more confidence going with them.

If you’re just trying to get the cheapest install possible, they’re probably not the right fit. But if you care about doing it right and getting a solid system that will hold up over time, they’re a great choice.

Overall, very happy with how everything turned out. The system is working well, and they were responsive whenever I needed follow-up.“
