I moved into my condo in October of 1996, and with the exception of regularly changing filters, never had any routine maintenance done on my HVAC system. Probably late in the summer of 2003, I had my first problem. Two plugs on the indoor condenser unit, were blown out, with water leaking, after which the thermostat and fan inside the condo still worked, but the fan in the outside unit no longer worked, and neither did the heating and cooling. Probably in July of 2004, a friend of mine fixed the system, and got it to cooling again. He told me that a wire had burned thru in the outdoor unit, and after he replaced it, the outdoor fan ran again, and the cooling system worked. Probably in the late summer of 2005, the same thing that had happened in 2003 happened again, with the plugs blown out of the indoor condenser, with a water leak, and the outdoor fan no longer running, altho the indoor fan and thermostat continued to work. During the winter I tried using the emergency heat button, but it didn't seem to work, and I can't recall an indicator light going on when I switched it on, so I switched it back off. In the time since then, the thermostat and indoor fan have continued to work. On Wednesday November 9, I turned on the emergency heat button, and no indicator light came on, although I did smell the heating coils heating up. Since then the the indoor fan no longer works. The HVAC system is the original one installed in 1984 when the condos were built. Any observations and opinions from you other board members as to whether I should get second or third opinions about getting a new HVAC system due to the age of the one that I now have?
