Cornerstone Pros - Air Conditioning, Plumbing & Electrical

A Cornerstone tech came out for my annual electrical system check. He identified the cause of some issues I was having, fixed what he could, and provided information to me so I could easily address the rest later when I buy a couple parts. Very informative, courteous, and really went the extra mile. All at no additional costs above annual membership. The price I listed is for the whole year and includes electrical, AC, and plumbing.

Called Saturday night to get an emergency estimate on our failed heat pump. Christian was at our door Sunday morning to do the analysis. Best service we ever had from an HVAC company. We're hoping the actual repair will go as well. The actual repair was just a few days later and Ricardo did a masterful job. It was a big job, but he was thorough and courteous, and after using it for couple days our system is working very well. We appreciate the service of the technicians and the people in the office as well. When we called,they answered the phone. When we text, they text back. We are not used to this level of communication and we love it.

Great company to work with. They do excellent work, arrive in a timely manner, and have great communication. especially keeping you informed and letting you know when your technician is on the way. I’ve used them in the past for plumbing concerns and recently again for a water heater installation, and every experience has been smooth and professional. What truly stood out was their thoughtfulness—after learning we had just welcomed a new baby, they sent their technician with a gift for our newborn. Such a kind and meaningful gesture. Highly recommend.

We asked the plumber to replace the broken pipe near the main valve. No digging was involved. Took about an hour and charged us $400. Initially they asked for over $700. This is way too much than I expected. I asked for several others and got quote of between 200-275. Sadly my husband never asked a second opinion. Be mindful of their prices and ask for itemized receipt.

Great service, would recommend this business! The process was very easy and they were able to come out same day to fix our previous handyman plumbing. Kathleen was incredibly kind and helpful with booking the appointment. Jonathon C. was super knowledgeable, patient, and personable. He explained everything, which is very important since I am a young homeowner. He gave more counter space underneath which was an added bonus (:
