I spoke with Gordon on Wednesday about repairing my Carrier AC furnace. After explaining to him the symptoms of my unit, he said he didn't think it was the motor. He sent Nathan out the following day to diagnose the furnace and it turned to be the motor. The wheel needed cleaning as well. Nathan took the motor out and returned the following day to complete the job. Gordon and Nathan, both, came across as being very nice, knowledgeable, and professional. They didn't pressure me into purchasing something I didn't need, like others had attempted to do. I'll give these guys a 5+.

Nathan was very efficient and explained everything he did so I would understand; also had before and after photos. Great...

Total Home worked hard to meet our needs. They gave me several options to choose from and got the work done quickly. I would recommend them to a friend. We needed a whole new system and they gave us a fair price.
