I had concerns because I read a lot of negative reviews about ProFlame. I had a ProFlame tank in my new house so I went with ProFlame anyway. (One of the other companies never even called me back.) I found them to have excellent service, great prices and they even helped me out and waited for me to complete my paperwork. I was supposed to have my paperwork filled out on Friday and got so busy I had forgotten. I had to work on Monday and Tuesday when they called to remind me, I had a few meetings. Finally I got my paperwork done by 2 pm so I figured the ProFlame Service Tech would have to reschedule. ProFlame still came out, filled my tank, inspected and started up my liquid gas appliances and got everything going great. I wasn't even home and my daughter in law said everything was great. Thanks, ProFlame!
