Talking About Air Ventilation Systems

Common Problems Your Air Conditioner Might Encounter

Over the many years that you own your air conditioning system, there are many problems that you will eventually find yourself needing to address. Without a basic knowledge about addressing these issues, you may find yourself at a loss for what to do in these situations.

Pest Problems

Pest problems can be a major problem for any home, but these vermin can be very damaging to the air conditioning system. Rodents and squirrels can chew holes through ducting, which can drastically reduce the system's ability to move air through your home. Also, these pests can build nests that may inhibit the moving parts of the system from working. Whenever you notice that pests have started to target your system, you should contact a pest control professional as soon as possible to remedy the situation. You may also find that it is wise to have a HVAC professional visit your home and inspect the system for damages that the pests may have caused.


Corrosion is a serious problem for air conditioning systems as it can cause the air conditioner's moving parts to start to malfunction. You can help to prevent corrosion from forming by regularly cleaning the exterior to remove any dirt that may have gathered on it so that moisture can dry as quickly as possible after rains. You may also want to occasionally peer through the vents on the exterior unit to check for signs of rust on the interior. Whenever rust is noticed, it should be removed so the metal can be sealed. Otherwise, the rust will gradually worsen and spread.

Clogged Intake Vents

The exterior intake vents must be clear for the system to be able to pull in enough air to maintain sufficient pressure. Unfortunately, leaves and sticks will often get stuck in these vents. Eventually, enough of these materials will get stuck to restrict the amount of air that can enter the system. If you find that your system is not providing as much air as it normally does, you should check to make sure the vents are completely clear.

Lack Of Refrigerant

If you ever notice that your air conditioning system is blowing warm air into the home. This can indicate that the system has insufficient amounts of refrigerant or the refrigerant may have degraded enough to no longer be able to function effectively. Most air conditioning systems make checking the refrigerant level easy, and you may be able to perform a basic refrigerant change without hiring a professional. However, if the refrigerant is low, this indicates a leak is present, and you will need professional HVAC repair help to identify where the leak is occurring.
