Happy Customers

“I moved to Sterling, VA in December and called Thermo Flow due to a heating issue and spoke to Ibeth. She was very knowledgeable and scheduled a technician to come out right away. Walter the technician quickly diagnosed the problem and explained everything to me so I had a full understanding of the problem. He told me a fair price and was able to fix it the same day. I was very pleased especially since I wasn’t familiar with any HVAC companies in the area. I will continue to call Thermo Flow for my HVAC needs.”
“I am a busy Project Manager for a mid size construction company and needed to find a local installer for an immediate project. I searched on a wholesale equipment website for local HVAC companies and found Thermo Flow LLC. Eduardo responded and came out the same day to look at the construction site. He sent me an estimate later that evening that was within the budget for the project. He also got started right away and kept me up to date all the way through the project. He and his team completed it about a week before I anticipated and the work was excellent quality. I will continue to use him and his crew on all future projects.”
“I had an emergency situation and a bad experience with a previous HVAC company. I found an advertisement on a mailer that I received a week earlier and decided to call Thermo Flow. I spoke to Wendy. She was very professional and assured me that she would have a Master Technician come out as soon as possible to diagnose and fix the problem. Within the hour Eduardo came out to perform a diagnostic. He quickly found the problem and within no time had a solution that was within my price. My husband was proud of me that I had fixed the problem by the time he arrived home from a business trip but I assured him I couldn’t have solved it without Thermo Flow. I am forever grateful!”
