I had a fantastic experience with Z & R HVAC services when they installed my AC. The technician, Hossain, was incredibly knowledgeable and professional. He not only completed the installation efficiently but also took the time to explain the system and answer all my questions. The quality of their work was outstanding, and my new AC is working perfectly. I highly recommend Z & R HVAC services for their excellent service and expertise. Thanks to Hossain and the team for a job well done!
