Eduardo Ramirez was my technician with Cornerstone Service. He was amazing! Very kind, very knowledgeable. Explained to me the things that were wrong with my A/C unit, what needed to be done and why and then he did the work. He was on time got right to it. He also talked to me about the kind of air filters I had and how often to change it. And then changed it for me so I wouldn’t have to get on the ladder. Unit is running great now. Highly recommend this Company and Eduardo.

I have had three air conditioning companies come out over the last two years and I was beginning to think they were all shady and overpriced. Cornerstone, just proved me wrong. They were the most thorough company I’ve worked with and they were honest in their explanation about what was wrong. They are the only company that made me feel as though they were actually trying to help me. They really do exemplify a gracious spirit and their customer service is unmatched in their profession. Eduardo represents this company well. They are fortunate to have him.
Tonya came recommended from another contractor and she jumped on my project and they took off with it. This is a small company that can handle commercial projects. Give them a chance to show you what they can do!
The team at Cornerstone is second to none! I was lucky enough to have them assigned to me by my home warranty company, and what a blessing it was. As usual, the warranty company really fumbled the ball on the claim, assigned a scam artist of a service company AFTER they had already assigned Cornerstone, and tried to deny my claim based on the scammer's completely inaccurate assessment of our air conditioning issue. Tonya was very understanding of the massive error my warranty company had made in the double booking, and made sure her tech came out the same day to provide a second opinion on the scammer's assessment. Eduardo spent almost 3 hours at our house meticulously going through our system as he verified key components were operating efficiently, finally concluding it was a 50 part that needed to be replaced instead of the need for an entirely new system that, you guessed it, the other guy said we needed. Eduardo did all this while I was glued to his hip the entire service call, and educated me the whole way on what he was doing and looking for. Cornerstone then worked with me to get my warranty company to overturn the claim denial in favor of their correct assessment to make sure the only money that came out of my pocket was the warranty deductible. Honesty and integrity can be hard to come by in the business world, especially service industries such as this, but the Cornerstone team understands that these 2 values will create client relationships that go well beyond the immediate need. As long as they are in business I know exactly who my team is for any AC needs. It's Cornerstone!
Do not use this company.. We had a new system put in our attic costing 9,000 dollars. It leaked all over the ceiling.. creating a huge mess.. now they will not return our phone calls to help us. This work was done 2 weeks ago. Horrible customer service.
Great service. Eduardo was nice and knowledgeable. Performed the service fast and the price was good.
My A/C compressor 'died' the last week of summer. I must have called a dozen companies for an estimate. Every one of them insisted I 'had to have' their top of the line hvac system : heat, air, rewiring, and new duct work ! Fortunately I kept checking around and found Cornerstone Service Contractors. Tonya was the first person that actually listened to what I wanted. Her expert technician examined my system and gave me a clear explanation. Bottom line, they saved me thousands of dollars over the closest competitor. Find someone who listens, does great work and saves you money-stick with 'em !
I signed up in 2019 for the silver plan service contract. I have been unable to get Cornerstone to answer their phones let alone come out for the winter ac maintenance plan. I would not recommend this company...proceed with caution!!
