I would give One Hour Air Conditioning & Heating "Zero Stars" if that was possible! Their service plan provides nothing! They charged me $400 to put some refrigerant in my system, and told me it would have cost me even more without the service plan! Right now, I am stuck under the plan, which I thought was actually doing something for me. But I have already found somebody else to do my work cheaper for me. One Hour Air Conditioning & Heating wanted to charge me $2,400 for a new unit, but I have found someone to do it for $1,700!
