Diversified Thermal Services has been providing refrigeration maintenance and repairs at my Ice Skating facilities for the past sixteen years. Their employees are very reliable and knowledgeable. The service reports are clear stating the services performed and any possible recommendations needed to keep the equipment running in top condition. If my chillers go down so does my business, therefore I will only entrust my livelihood in the hands of Diversified Thermal Services.

I have been working with Dan Bailey and the Automation Department at Diversified Thermal Services for a few years at multiple locations in Southern California and have always received high quality work and outstanding customer service. Diversified has installed new DDC Controls Systems for chiller plants, upgraded exisiting DDC controls, and repaired multiple control systems throughout our portfolio in Southern California. The Automation Team has demonstrated oustanding knowledge of controls and building systems far superior to any other controls vendor I have worked with over the years.

We at Mission Hospital have been using Diversified Thermal Services exclusively for the past 17 years as our HVAC contractor. Being a full service hospital that runs 24/7 365 days a year, we are prone to breakdowns at all, often inconvenient, hours that require emergency service. Diversified Thermal is a full service company that has always been there for us at these desperate times. They have installed cooling towers, air handlers and package units along with providing exceptional preventative maintenance and service on our chillers. Their staff is always friendly and courteous and their service is prompt and professional. I would highly recommend their services to any company or hospital that requires service on their HVAC equipment.

“Since 1992, I have had a great working relationship with Diversified Thermal Services. They quickly figured out the issues that were plaguing our Vapor Recovery Systems. They are not only extremely efficient at the component level but also with the complete systems. They have saved us millions of dollars over the years by implementing a very precise maintenance program. They strive to make sure that our units are always in compliance with all local, state and federal regulations. They have taken ownership and it shows.”
