Aires Cooling And Heating

Purchased a furnace tune-up from Aires through Groupon. It was completely worthless because 4 days after they inspected it I woke up in the middle of the night to some awful loud screeching noises from the furnace. Had another company come in to inspect it and they found 2 of the 4 burners were running 50 degrees lower than it should be, the heat exchanger was broken, and motor was completely blown. The Aires technician missed all issues during his "inspection". What I was told by the other technician is the 2 burners looked to be broken for awhile which caused the other 2 to overcompensate which warped some components causing the catastrophic failure.
