We have a 9 year old Lennox 2 zone system. Our smaller unit is not blowing cold air. Someone came out in the fall and replaced the capacitor, expansion valve and recharged the system and $XXXX later we have no cold air downstairs. We are being told that a coil is leaking freon. Options are to replace the coil and condensor or simply replace the whole system. The tech that came out suggested that when considering the cost of replacing the condensor and coil, we may as well replace the whole unit. And then he wants to replace the furnace as well. We have had no problems with the furnace. According to the tech, if you replace the AC with a modern system, you should replace the furnace as well.
Are we being given accurate info? This would be quite costly no matter which option we choose.
