This was the first time I used R&R Mechanical Services. I called them because my place wasn't heating evenly. There were hot spots and cold spots. So R&R came in and assessed the situation. Then they relocated the thermostat which fixed the problem. R&R was easy to reach and showed up on time. I would recommend them. They got the job done! Five stars for service and quality. I would use R&R Mechanical Services again.
