They inspected our AC and told us we needed a new one so we bought it.They told us the same thing in our new home two years later. The second unit had bad coils because they did not replace them when they sold us the second unit and we had to buy new coils. They new coils leaked every year for four years and they charged us for filling it with refrigerant with out looking for the leak or fixing the leak for four years. The second unit then died and we were told had to be replaced. We hired another Ac company for a second opinion who told us the four year old unit did not have to be replaced and that new coils we bought were several years old, bent, with an active frion leaking and that CF should not have filled the tank every year with inspecting to find the leak and they must have installed new coils. Company # 2 sold us new coils, fixed the problem and we have not had a problem since.
