Where do I start, they rescheduled on me 2 times knowing that I didn’t have any heat.finally I get a technician to come out on Sunday evening to figure out the problem and charge me $190 to tell me a roll over switch is no good and it cost $635 to change a switch that’s a size of a quarter with 2 wire connected, it wouldn’t take no longer than 5 minutes..so they finally come back 4 days later with the wrong switch and turn the boiler on and the switch burn again to tell that the boiler need to be replace and it was going to cost $16,000-$19,000..so I called some one else and I was told that my boiler was fine and he brought the right roll over switch and poof my heat works again and it been working since I got my $16,000-$19,000 estimate…so be careful with this company.
