There’s not an appliance out there that lasts forever—which probably goes without saying. No matter how well it’s designed or cared for, your household air conditioner has a limited lifespan. When it nears the end of that lifespan, it’s a good idea to have the system replaced before it experiences a catastrophic breakdown.
The last thing you want is to end up stuck inside on a hot day (since that’s the most likely time for system stress to cause a failure) with no relief in sight as you rush to schedule an AC replacement (and coincidentally risk not selecting the right system for your home). Additionally, an aging air conditioner will end up wasting money through inefficient operation since not even the most careful maintenance schedule or AC repair in Nashville, TN can maintain its efficiency once it reaches a certain age.
