Our experience with TFS has been so good from start to finish. They answered all our questions and made the process understandable. Every person we had contact with was friendly, knowledgeable and professional. If you’re considering a solar installation TFS is definitely the way to go.
Our solar installation experience was terrific. You all were responsive and on-time. You never left us guessing. Special kudos to Willy and his crew. They did a complex job efficiently and without any interference in our daily routine. They all seemed well organized, got along well with each other and enjoyed their work. Most importantly they installed the solar panels with minimal change to the appearance of our house and left the job site clean with nothing for us to pick up or restore.
Call I called there multiple times to get a quote but they never return my calls nor sent me any emails tried to talk to somebody else but the person who answers the phone Laura won't let you speak with someone else so I'll just take my $20,000 elsewhere it's sad because I wanted to get someone in Tucson to do my job and they are an r e c accredited company but looks like them ending up using someone from Phoenix cuz I can't speak with anyone there
