We bought a Amazon Local voucher ($39) for a furnace ""TUNE-UP"" and inspection. I was away when the technician serviced our furnace. After the ""TUNE-UP"" he told my husband it needed a deeper cleaning which was an additional $159. So now we are at $198 for our $39 ""TUNE-UP."" We paid $198 for 1 hour of work. Called ESCO and all they would say was my husband gave him permission to do the ""extra"" work. The work that I presumed was covered in the voucher. Beware of Esco.
