brad clarkeI'm a property manager in the greater durham triad area, and I recently had the plesure of working with Thermostat Master's tech Tanner. We had an unfortunate situation where a compressor blew the day after a new move in, even though Tanner was at the end of his day and had probably already done many jobs, he travled from across town to get the work done after hours. Tanner has an outstanding worth ethic, Thermostat Masters is lucky to have him!Posted on Google
Benjamin WashburnI can’t recommend Thermostat Masters highly enough. I came home from a 10 day vacation to an 81 degree house on a 100 degree day and thought I was looking at a major A/C repair. Riley was immediately responsive and accurately diagnosed the problem. Before long, my system was back up and running - cool air blowing throughout my house. What impressed me most was Riley’s approach. Instead of guessing or jumping to the most expensive possibility, he methodically worked through the problem, explained what he was checking step by step, and quickly zeroed in on the actual issue. His diagnosis was exactly right, and the repair got my system cooling again immediately. I also learned a great deal, and he was happy to share his knowledge. It’s rare to find someone who combines technical expertise with honesty and great communication. If you’re looking for an HVAC company that will diagnose the problem correctly the first time and treat you fairly, I wouldn’t hesitate to recommend Thermostat Masters. Thank you, Riley. My family will sleep cool tonight thanks to you.
