When To Replace Air Conditioner ?


This summer has been particularly brutal for the Midwest, and having a working air conditioner is practically a must right now. The last thing you want in this kind of heat is to have your AC die on you, so look for the following signs that your air conditioner is in need of repair or replacement.

Strange Sounds

A good air conditioner will barely make any noise when it’s working. You might hear a faint whoosh when it’s turned on, but that should be it. If you notice squeaking, grinding, or rattling noises coming from your air conditioner, there is something wrong that needs to be fixed as soon as possible.

Strange Smells

Musty smells coming from your air conditioning unit or your ducts is a sign that mold and bacteria are growing within the system. This is obviously not supposed to happen and is a sign that your AC isn’t working as well as it should be.

Warm Air

Feeling warm air coming from your ducts defeats the purpose of having air conditioning in the first place. This is usually a sign that your unit is either leaking coolant or has a bad compressor. Fixing the problem is sometimes as easy as replacing a blown fuse, but you shouldn’t hesitate to contact a Fox Valley heating and cooling company if you aren’t sure what the problem really is.


If you see moisture around an AC unit, it is either due to a blocked or broken drain tube or a coolant leak. Either way, it is a problem that needs to be addressed.

Poor Air Flow

Finally, an air conditioner that isn’t working well might have poor air flow. This could be caused by a bad air compressor, or it could be that your HVAC system’s air filter is blocked and needs to be changed. Air filters should be changed about once a month, but any other culprit will need to be addressed by a trained HVAC repair contractor.
