HVAC company accused of breaking D.C. gas furnace

COMPLAINT: Kuan Jeang, Rockville, Md.

I hired B and B Heating and Cooling to repair a natural gas furnace. I'd noticed that occasionally the furnace flame would kick on but the fan wouldn't follow.

The technician was polite and courteous, but it was clear he had no experience with this type of unit.

He decided the problem was a controller circuit box and said he didn't have the exact part but could replace it with a universal box. However, the wiring configuration in the universal box didn't fit the previous wiring.

He re-read the direction sheet and remarked that he was confused. He made several calls to the home office and said he was instructed to jump two wires together. He did this and reassembled the furnace, then started it.

Within 10 seconds, he blew the transformer, which started smoking. He also blew the fuse in the fuse box.

He called his supervisor, who arrived and looked at the furnace and attempted to rewire the universal box as the technician had. This didn't solve the problem, and he blew another fuse.

Four hours later, they'd made no progress, so I asked them to reassemble the furnace and leave, which they did. They wanted me to sign the form and pay for the diagnostic visit, but I declined to do so.

I started with heat and an occasionally balky fan, and I was left with no heat and a completely nonoperative furnace.

DESIRED RESOLUTION: I'd like them to remove their diagnostic bill since they neither diagnosed the problem nor fixed the issue.

Sounds like a defective blower motor or fan limit controller from here. The balky sound from the blower motor may be defective bearings or motor windings. As far as blowing fuses and somking transformers.Incorrect wiring most likely is the issue. Not all technicians are created equal. Furnace repair 101 pretty sad story.
