Consumer from Bethesda, MD

I did not use them but met with GAC to discuss options for an HVAC replacement. They sent a sales rep who wanted me to buy an air conditioning when I only needed a furnace. I told him which brand I wanted at the beginning of the meeting and he waited until the end of the appointment (two hours later) to say they didn't have that brand in stock. He also called later and wasn't straightforward about a sales incentive program they had. At one point in our meeting, he said I was "argumentative." I don't think he was very experienced, so I let the comment go without retort, but I was very unimpressed with their sales department. I wound up hiring a different vendor that I found more straightforward and responsive to my needs.

The maintenance technician sent an exorbitant quote to repair a part that wasn’t installed correctly by their installation team. I can’t recommend GAC now, especially since upper management decided to eliminate Quality Control to favor sales instead.

Front office does not promptly respond to service calls even from preferred members and over 20-year customers.
