How do I know when it's time to get a new AC unit for my home? Details in body.
My current AC unit is 11 years old. I live in the south of the US (hot & humid summers). I've never had an issue with the unit. I have an HVAC service that I've been a customer of for the past 5 years that does routine maintenance service on it & they recently advised me that it's time for a new unit (not cheap, 12k - 16k price range).
How do I know that they aren't bullshitting me? I'm in sales myself so I know the sketchy side of it lol. 12k - 16k is a lot of $ for me, so I don't want to buy a new unit unless it's truly going to die in the near horizon.
