The blower motor on our 18 year old furnace went out on very cold afternoon. Eric was out in a couple of hours and replaced the motor. In less than 5 hours from the motor burning out, we had heat again. I've called Carr's Air Maintenance for our central air issues too. I've never been disappointed in their work.
