Company Response: We resolved this with the customer. The price charged was fair and in line with how we bill our work (it took a bit of time to troubleshoot). Lightning damage causes very unique problems on furnaces. We have seen many this summer like this. In this case there was a gas leak in the furnace which was small enough we did not notice at the time of service. Since we did not return to the residence (as we were not asked to) we are unsure. Regardless we have been working with this customer to make things right and right any wrongs, because it is the right thing to do.
