Even when there is something wrong with your air conditioner, it might continue to blow air. However, you shouldn't assume that the AC unit is functioning properly just because it is blowing air, especially if it doesn't seem to be cooling your home (or at least not cooling it as much as it ought to be). There are several possible reasons why this may be occurring.
One of the most common reasons why your AC is not blowing cool air is that there is something wrong with the compressor. One issue is that you might have a blown capacitor. Another possible problem is that your motor has seized. You will need a professional AC repair technician to diagnose and repair the unit in either of these cases.
If the AC repair technician tells you that you need to replace the compressor, your options are either to replace the compressor or replace the entire AC unit. If the compressor is under warranty, you'll only have to pay for the labor, so it would make more sense to have your AC repaired. However, if you are required to pay for the compressor, you'll first want to compare the price of a new compressor with the price of a new AC unit. If repairs will cost more than the value of your AC unit, you'd be better off replacing your AC. However, even if it's less expensive to replace the compressor, keep in mind that your AC unit might not last much longer if it's old, and you'll be wasting money on the compressor.
Your AC Needs a Recharge
Another cause of an AC not blowing cold air could be that you need a freon recharge. You won't want to wait before recharging your freon because it will cause your AC to become more expensive to operate. In some cases, it's legal to recharge your own AC unit, but it depends on state and local laws. You may need to obtain a license and there might be specific professional standards you'll need to follow. Also, you might have a much harder time purchasing freon if you aren't properly licensed.
You Need a New AC
In some cases, you may need to replace your entire AC unit. However, this is not necessarily the case. After having a conversation with an AC repair technician, you can find out if an AC repair or replacement is the best option.
