Most of us expect our air conditioning unit to work perfectly time after time, throughout the year. However, your HVAC unit may occasionally fail to work if not properly maintained.
If you are experiencing this issue lately, there is no need to worry. It could be easily fixed as a do-it-yourself project or, in some cases, by hiring a professional expert for AC maintenance in Lawrenceville, GA.
Reason Why AC Won’t Turn On and How to Troubleshoot?
Here are some reasons your AC is not switching on and some ways to troubleshoot it:
Your air conditioning unit has suddenly stopped working. You panic and begin calling various air conditioner specialists. Before proceeding, have you inspected the temperature on your thermostat? A faulty thermostat can impair the effectiveness of your air conditioner.
First, ensure your thermostat’s screen is turned on. It cannot prompt the AC to turn on if it is turned off. Second, if you have a battery-operated thermostat, inspect the batteries. If your batteries are fine, check the operation of your thermostat.
Set it to a safe temperature, 5-6 degrees lower than the ambient temperature.
The Refrigerant is Running Low
A refrigerant lack could be one of the causes for your air conditioner not working. A refrigerant is a cooling fluid found in the coils of an air conditioner.
It is primarily responsible for delivering the preferred cool air from your air conditioner or hot air in the case of a heating system. The lack of refrigerant is not due to your air conditioning unit depleting the fluid. In this case, leakage is most likely to blame.
Cracks in the AC coil may form over time, resulting in leakage. Furthermore, failing to schedule regular AC service in Lawrenceville, GA can result in corrosion in the long run.
Obstructed Air Filters
Do you know the last time you cleaned your air conditioner’s air filters? If you answered no, you have a serious problem because your air conditioner may be unable to function properly due to dirty, obstructed filters.
Cleaning the filters is essential, regardless of the air conditioner you have. The air filters’ job is to make sure of proper airflow. However, if they become clogged with debris, airflow gets obstructed. In this case, your system has to work tougher to cool your home, and it may eventually stop working.
Dirty air filters can also cause your outdoor AC unit to freeze, interfering with its operation and, in some cases, causing it to fail.
The evaporator coil is placed in the indoor machine of your air conditioner, while the compressor is located in the outdoor unit.
The coolant line connects these two parts. Warm air from your home does not meet the refrigerant when airflow is restricted. The refrigerant then cools to the point where any moisture on the coils freezes.
