Your AC won't last forever, and you might be thinking that it is time for an air conditioning replacement, but not be quite sure. There are a few surefire signs that it is time for you to replace your AC. 

1. You Notice More Humidity 

Your air conditioner does more than just cool your home; it also lowers the humidity level so that you have comfortable, non-muggy air.

If you have noticed a sudden spike in humidity in your home, this is a sign that your AC unit is not functioning as it should and might need to be replaced. Higher levels of humidity could also be due to problems with your ducts.

2. You're Often Calling For Repairs

If an AC unit is in good shape, you shouldn't have to be constantly calling to have it repaired. If you are frequently having to have your AC unit serviced, you should look into getting a new unit.

If you continue to have your air conditioning constantly repaired, the repair costs can quickly start to add up. This is money that you should be putting towards new AC. 

3. Your Unit Is Very Old

The lifespan of central air conditioning units is 15 to 20 years. As your unit gets older, it gets less efficient, breaks down more, and starts to cool your home improperly.

Older air conditioning units use something called freon to help cool your home, which is slowly being phased out of use due to environmental regulations. As freon gets phased out, it has become more expensive to replace, just adding to the cost of keeping an older AC unit.

4. Your Cooling Bill Has Spiked

Your cooling bill should not be outrageous if your AC unit is running efficiently and properly. If you have noticed a sudden spike in your air conditioning bill, but you haven't made any changes as to how you are running your air conditioning, this is a sign that the air conditioning unit is not operating at its most efficient levels.

If you have had many repairs to your air conditioning and your utility bills still aren't going down, this is a good indication that its time to replace your air conditioning completely. 

Pay attention to your air conditioner and see if you notice any of these signs. If you do, it's a good indication that its time for you to get new a new air conditioning system entirely.
