Poor customer service and communications. I have left messages and don't hear back for days. Poor work installation. This past year (2025) my inverter failed. The initial technician that came out, took pictures that were sent to the manufacturer. The manufacture determined that the unit wasn't installed correctly and denied my warranty claim, because the wiring and seals were not installed correctly. I did further research and discovered that the unit was in fact install incorrectly. While it has a waterproof cover the unit is not supposed to be installed in direct sunlight. The manufacturer explicitly states this in their installation instructions. The inverter was mounted so it faces directly south with a full southern sun exposure, which can 100-110+ degrees in summer. As I did my research, is learned that they weren't a certified installer for the inverter, from Fronius. Nor are they identified as certified by the panel manufacture, Silfab. They felt no obligation to stand behind their world. I had to pay to install a new inverter. We went 6 months of prime solar generation without solar, which cost a significant sum to pay for heating bills.

Bill from Copycat was instrumental in helping us get our insurance company to cover the cracks. We would not have gotten any coverage without his help. Copycat installed two insert fire places for us. Their team was amazingly knowledgeable and answered all our questions both about the installations, tips on how to use them and care and maintenance. We would definitely recommend them.

The installers did an excellent job, finished in the timeframe they had promised, and even helped us arrange with a local electrician to incorporate under-mantle lights into the design. We are delighted with our new fireplace. One suggestion: it would be helpful as customers are picking out their stone, etc, to see examples of Copycat's beautiful work, in addition to the trade catalogs and sample boards. Those decisions are tough, and pictures would be helpful, besides being great advertising of their quality work.
