Air Conditioning Fan Basics - How to Tell If Your Fan is Bad
There is nothing more annoying in the summer than a fan that won't work. It is very annoying when you have to work and you have to crank up the heat only to find that the fan will not spin. The best way to handle this situation is to make sure that your fan is properly functioning. A poorly working fan is a huge hassle and can cause you to miss work. The most common reason why a fan stops working is because it doesn't have enough power. You can fix this by changing out the existing motor, if the fan is still too powerful for the current setting then you may have to get a fan that has a lower wattage.
The thermostatic switch on your heating and cooling system controls your HVAC blower. The blower pushes hot or cool air through your house until the indoor temperature on the thermostatic switch is achieved. There are usually two settings on the thermostatic switch to control the fan. The one that is used most often is the auto setting and if this setting isn't the problem then you should check the other one.
If the auto setting is the problem then the fan must be calibrated to the correct setting. You should contact your heating and air conditioning company and they should be able to do this for you. Usually the fan is calibrated to have the room temperatures at a certain temperature. This means that when the fan is spinning it is trying to keep the room temperatures at those temperatures. If the fan is running faster than the room temperatures, the fan is trying to pull the heat from inside the room and putting it back outside.
One of the easiest things you can do to test the performance of your heating and air conditioning unit is to perform a fan testing. All you need to do is purchase a new HVAC unit and hook it up to a fan. Start the motor up and then set the control knob to the desired speed.
Once you have set the fan to the desired speed, you should open the vent ducts. You can use a flashlight to see what is going on inside of the ductwork. Once you have opened all of the ducts you should close the fan doors and set the hvac fan on low. Check the airflow in the vents using a flashlight. If there is excessive airflow (cooling) in the vents than you may need to purchase a new fan or check the heating and cooling unit's ventilation ducts. If there is inadequate ventilation in the ducts than you should probably replace the entire heating and air conditioning unit with a more efficient model.
After you have performed all of the fan testing and the air conditioning unit has been replaced, you should check the conditioner's power supply to make sure that it is operating correctly. Sometimes the power cord for the wall convectors is bad. If the conditioner power supply is not working correctly, it can cause a variety of problems including blowing cool air, not having a cool temperature in the house and sometimes even fire and burns. It is very important to make sure that your HVAC system is operating properly.
