2 Signs Your Home's Central Air Conditioner Needs Servicing

Even if the weather outside is not overly hot, you may have noticed that the temperature inside your house has become uncomfortably warm. If so, you may suspect that there is something wrong with your AC unit. If so, look for the following signs that your home's central air conditioner needs servicing.

1.  Decreased Air Flow Coming out of Your Vents

When your house is no longer as cool as you wish it to be, the first thing you can check is the air coming out of your vents while your AC unit is running. Normally, there should be a steady flow of air that is detectable when you place your hand over the vents.

However, if you have discovered that there is decreased air flow coming from your vents, there is most likely a problem inside of your AC unit. The most common and easiest problem that can cause this issue is a dirty air filter.

Try replacing the filter with a new one even if you do not see any noticeable dirt or debris on the old one. If this does not increase the air flow, there could be an issue with the fan or motor that will need to be repaired by a professional.

2.  Moisture Buildup Inside of Your Air Conditioning Unit

Another sign that your air conditioning unit needs to be serviced is when moisture starts building up on the inside of the unit. This moisture buildup is detrimental to the air conditioner because it can not only interfere with the electrical components of the unit, but it can also freeze up and create a layer of frost on the compressor and refrigerant lines.

The most common cause of moisture buildup inside your AC unit is a low level of refrigerant. Because of the low level, the compressor is unable to cool the warm air properly while releasing the heat. When this drastic change in temperatures happens, condensation starts to form.

Since a low level of refrigerant is almost always caused by a leak within the system, simply recharging your air conditioner will not solve the problem. You will need to have the leak repaired.

If you have tried a few simple things to remedy the scenarios above without success, there may be an issue with your air conditioning unit that requires a professional. Contact an HVAC contractor who offers AC services to have them inspect your AC unit and service any problems that they find.
