When an air conditioner gets old, it can present a number of problems.
The most common problem occurs when an air conditioner sounds like it’s running normally, but there is no cool air coming from the air vents. There are a few causes for this, the first being an old air filter. Often when an air conditioner has been running for a long time, the air filter will get dirty and clogged leading to a block in air flow. To fix this you can order an air filter online or buy it from your local HVAC store and have an air conditioning repairman replace it for you. Another reason why your a/c may not be working correctly is the circular fan inside the air conditioner. The circular fan may not be working because the blades are bent or damaged or it has gotten rusty and won’t move easily. It is best to replace a damaged fan rather than try and fix it yourself as this may only make the air conditioner worse. One last reason for a dysfunctional air conditioner could be its internal thermostat. If the thermostat is broken the air conditioner may think the room is at the correct temperature and therefore not work. While all three of these problems can be fixed by anyone, it would be wise to ask an a/c service man to make the repair for you. The best way to avoid all of these problems would be to have your air conditioner serviced every year. An annual checkup will ensure your air conditioner is in prime condition.
