If your air conditioning system is blowing air but the air does not feel cool, this can be due to different things. Below are some possible problems so you can determine what is wrong and have a cool home.
Low Air Flow
One problem that can cause the air not to be cool is having low airflow. One thing that can cause this is a dirty air filter. If your filter is dirty, then it is clogged up and air will not be able to pass through it. Fortunately, this is an easy fix as you will only need to replace the filter. Remove the current filter and write down the number on it so you will know what type to purchase.
There are different types of filters available. One type you throw away when it becomes dirty. There are also air filters that you can clean at home, so you do not have to replace it with a new one. These air filters do cost more but over time you will save money.
Another problem that can cause this is the evaporator coils. If there is a problem with the evaporator coils, frost or even ice will form on the coils. This will not allow cool air to flow but instead warmer air. You will find the evaporator coil inside the air handler which is close to the fan that blows when the air conditioner is running.
Hire an air conditioning contractor to look at the evaporator coil for you. They may be able to repair it, or the coil may need to be replaced.
You should check the thermostat to ensure it is set to auto and not on. If the setting is turned on, then your air conditioner will run 24/7. If this is the case the air may feel cool sometimes but warm other times. Turn the thermostat setting to auto to see if this takes care of your problem.
If your thermostat is old, now would be a good time to replace it. Newer thermostats on the market today are much better. This is because you can set the thermostat to turn off and on at certain times. For example, you could set the thermostat to turn off during the day while you are working, and then have it turn on an hour before you get home. This way you will walk into a cool home.
