The Trane central A/C and heating unit in our Florida condo is 9 years old and have not had any issues with it. We are only there a few months per year and keep the temperature at 72 degrees when we are there and 76 when we are not. We change the filter at least once per year. I installed a Wifi thermostat to control it remotely. We have a Lennox A/C and heating unit in our home in Southern California and it has been operating since 1996. I repaired the controller board twice (replaced relays that burned out) and replaced the controller board once. I also replaced the exterior disconnect switch once. I also installed a Wifi thermostat on this system.
