I would give Service Legends Heating & Cooling a 5 for what they did so far. They put in a new furnace and a new air conditioner in, combining the whole thing together into one job, and it looks like it was all put in at one time. It's working good too! The old air conditioner was just about to quite and it would have cost a fortune to get it fixed, both in terms of repair costs and how inefficient it was compared to newer units. We ended up putting in a new furnace to match, so they both could run at 95 percent efficiency, rather than whatever a 30 year old air conditioner and a 75 year old furnace would run at.
