We had our heating and hot water system replaced with a Navian tankless system. Our contractor had it subcontracted out but we had nothing but problems. On one of the coldest days of the year the system went down and we couldn't get any help from the installer. In desperation I started looking for someone else and found Kyle. We discovered the system was incorrectly installed and and needed to be replaced. Kyle was able to get a new system that was still under warranty in a day. We haven't had any problems and he has made changes and additions to make the system work even better. All prices have been fair and work completed quickly. I would highly recommend him to anyone else that needs work on their tankless system.
