Dealing with Convertible for installing my new tankless water heater is very straightforward. Their service is simple, fast and friendly. Sale representative Marnie was very patient in the beginning to explain to us on phone about which model of water heater we need for our home and the cost for this job. Then, she sent the consultant Michael to come by and check our existing plumbing configuration. He was very knowledgeable and explained to us what they need to do to finish the installation and answer my questions about this job. A week later, the installer Kamil and his partner came by and they were nice and professional. They kept my space clean and dry and didn’t leave any mess in my home. We are very appreciated that they helped me put my old water tank on my car for return. Overall, we are very happy and sati with their professionalism and great service.
