We have used several heating and a/c companies over the years and are so very glad that we finally called Cornerstone. Matt Wilson provided us with the most information that any HVAC contractor has ever given us on any service call. He was respectful, thorough, patiently answered our questions and made sure that we understood all of our options. We wouldn't hesitate to recommend Matt and Cornerstone to our friends and neighbors.

Best A/C company in the Bay Area

Had my unit installed two years ago by Cornerstone Air and have used this company a few times for tune up and issues with the AC. This company is the most reliable, professional and knowledgeable company that I have encountered in a very long time. The employees are amicable and very knowledgeable. My A/C wasn't cooling when I got home a few nights ago, I placed a call to Cornerstone Air about 7:30 pm and my call was returned within 1/2 hour; the A/C was fixed the next morning. Kudos to them.

Trustworthy and Helpful

We've been using Cornerstone AC for a few years now and I can honestly say that they are a great organization. I've found them to be honest in their assessments of work that may or may not need to be done. Their service repairmen are clean, well-mannered, friendly, and make you feel comfortable around them -- they also take the time to explain the situation so that you understand what's going on. Their prices seem fair and reasonable, and they are available to assist you even in 'emergency' situations. I would recommend them to any of my family/friends - in fact I already have. Thank you.

Great Company - Honest Fair & Knowledgable

I recently had Cornerstone out to my house to fix my air conditioner they did a great job and provided a quick response to my call. The technician took the time to explain all the details to me which was so refreshing and I felt the repair price was very fair for the quality of service I received. I will recommend cornerstone to all my friends and family.

Extremely Dishonest

Absolutely crooked. Each technician seems forced to suck money out of you. They will quote some of the most ridiculous amounts hoping you do not know what you are doing. Do your homework then call around for quotes. Just do not call these Jokers.

Great Experience!

I recently called them at the recommendation of a friend to repair my a/c. They were prompt, professional and quickly found the problem. During their visit, it was determined that a previous company had sold me a part I didn't even need. I plan to stick with Cornerstone and would definitely recommend them as being a GOOD, HONEST company.

Honest...dont think so!

Don?t call EVER.
There is nothing worse than a push company that only care about the bottom line. I was in need of some repairs and this company out of all the companies that I called was the worst?only caring what year my unit was and if I wanted to replace it ..They were very rude when I asked about repairs only and I was told that my unit needed to be replaced without them even looking at it! If you need a good A/C company or HONEST company this is not the one?..beware of this company the will rip you off and tell you that your unit can?t be repaired but in FACT I did have it repaired and NOT replaced and for thousands of dollars less then what they told me OVER THE PHONE.

Honest

Hi,
I could not register on your page to give feedback, so I thought I would give this address a try. Briefly, I had a nonfunctioning (non-cooling) split unit in Brandon about two weeks ago. I called one of your competitors, (initials O.H.A) and they sent a technician that evening. His only solution to my problem was complete system replacement, and he would have it done that very night. After speaking with my wife we decided to get a second opinion, as his prices seemed high. We called you the next day, and received an appointment later in the day. Not only was your tech, Chris personable and informative, but also HONEST! He was able to replace a dead capacitor and a fan motor for a fraction of the cost of the ""Big Guys"", but also explained my several options, as my unit is, truthfully coming towards the end of its service life. In closing, I'll say that your service was head and shoulders above the others, your honesty was a breath of fresh air, and when the time comes, I will only do business with Cornerstone when its time to replace my system.

Thank you Cornerstone and thank you Chris. You are a credit to the business community.

Sincerely,
Ron Parker
