Over my many years in the Colocation industry, I have dealt with many mechanical contractors. Few have shown the level of professionalism, skill, and attention to detail as Keystone. This is why I put my trust in them to maintain my Critical Systems. I believe a contractor is only as good as the technician who shows up to service my units, and Keystone’ Technicians have proven time and again that they are the best choice in the industry for Host.Net.
I have been doing business with keystone for more than 7 years. In those years Keystone has been doing my preventive maintenance service for two 20 ton CRAC units and two UPS units in our data center. There have been times when emergency service has been needed and the wait time was much less than expected. I was very impressed that their service truck had all the parts necessary to repair the job at that time, saving critical down time and money. I found there pricing to be very competitive and service to be at the highest standards needed to make sure all equipment is working at its optimal performance. I found the service people to be very friendly, knowledgeable, all workmanship done in a professional workman like manor and understanding to all of my service needs. I would highly recommend Keystone Critical Systems for all of your needs. Do not hesitate to contact Don Cleaver, the owner, so he can work a plan that will fit your needs for all of your equipment. You won’t be disappointed.
I don’t quite remember how I was introduced to Keystone but I sure am glad that I was. I have been working with Keystone for the past 4 years and have come to rely on them for both their service and technical assistance.Keystone managed the replacement of two 400 ton chillers for our main operations center flawlessly with no down time or mistakes, coordinating with the manufacturer and the controls provider to deliver a complete system. They have provided technical services with our generators and electrical systems as well as providing service for our data center and base building cooling plant.When I needed information on fire suppression, my first call was to Keystone. I got the answers I needed along with building code references and budget numbers. They are definitely a good resource for both planning and implementation.
Project Manager / Facilities Management
EdgeConneX has established a working relationship with Keystone Associates to maintain and repair the mechanical systems for our key Miami, FL Data Center. EdgeConneX initially held a relationship with a large mechanical shop in Florida that was under performing and making many procedural issues causing us to seek better service. Keystone Associates is a premier data center supplier for services that contribute to the stability and longevity of the data center assets. Keystone’s work ethic, skills and knowledge of a data center environment are excellent reflected well by the quality and professionalism of their technicians and management staff. EdgeConneX has not experienced any downtime or human error work since bringing Keystone on as our mechanical supplier. With another Miami data center being built EdgeConneX will utilize Keystone Associates for that site as well. Keystone is considered a trusted partner providing EdgeConneX staff peace of mind knowing that the critical environment is running properly and efficiently. We highly recommend Keystone Associates as a premier data center supplier.
Director of Operations
Keystone Critical Systems and Advisors recently completed a very difficult mechanical upgrade project for us in our downtown Miami Colocation facility. The project was an extremely difficult project in which we worked in a live data center as customers began to expand and grow within the space. This project took much coordination, and required multiple levels of approvals throughout its course. I would not have trusted many mechanical contractors to complete the scope of work, especially considering the specific customers in which we needed to coordinate with and complete work within their caged areas. Keystone did a wonderful job in communicating all efforts through our required change control policy, coordinating with our Landlord in this building, and in all, completing a very challenging project with zero interruption to our operations or facility.I would recommend Keystone to any other Data Center providers for mechanical work performed. Definitely one of the stronger contractors, specifically in the SE region/market.
