It’s time for an AC replacement when the following happens:
1. You notice that the air coming out of your vents feels hot. This is a sign that your air conditioner’s compressor has failed and needs to be replaced. The compressor is the part in your AC system that moves heat from inside your home to outside, so if it stops working, you won’t be able to keep cool.
2. Your home feels warm even though it’s set to a low temperature. If you find yourself cranking up the thermostat and still feeling hot in your house, this could be a sign that something’s wrong with your AC unit—or it could just mean that there are some leaks or gaps around windows or doors.
3. You hear strange noises coming from your AC unit while it’s running. If you hear rattling sounds or squeaks from somewhere in your home when the air conditioner is running, this could indicate that something needs repair or replacement before it becomes a bigger problem down the road (like a leaky pipe).
