Tip & How-To about Heating & Cooling
On of the common problem with centralized A/C unit is a bad condenser fan. I have known people who called an ac technician to fix their ac because of a bad condenser fan and suggested replacing the whole unit! Costing them a lot of money when all it needed was a 50 dollars condenser fan! If the condenser fan do not run or it runs only when you give it a push, it'sbad. You will also notice that it is vey hot. When replacing a condenser fan you may want to replace the starting capacitor too. Replacing a condenser fan is not very hard, just make sure that the power to the ac unit is turned off at the breaker box. Confirm that the wires are not live by using a meter or an ac tester. The fan motor are held with brakets sometimes just screws. Most fan you can buy that has reversible rotation by just reversing the plug. Make sure it is blowing upwards. If not reverse the rotation. So if you notice that the unit is not putting out cold enough air and you went outside and noticed the compressor running but not the fan, turn off the AC right away and do not use it untill the fan is replaced. Running the unit with a defective fan can damage the compressor caused by overheating.
