I cannot recommend this company enough. Patrick attended the first time to try to diagnose the problem. On time, spotlessly clean and just so pleasant. When he returned with the part (which I had been told by 2 other companies was the board) it turned out it was actually the thermostat. So instead of $500 it turned out to be a $66 part!!! How honest is that????? Plus of course the service fee which was cheaper than the others had quoted as well. You guys are my go to in the future. Thank you, Jan (Sunbury)
