Dirty Filters
Dirty filters are one of the most common air conditioner problems. Usually, it results in insufficient airflow, causing your AC to malfunction. Dirty filters block airflow and reduce efficiency, leading to a frozen evaporator coil. The solution is simple: clean or replace the filters. You can clean or replace the filter or call a professional AC repair service to handle it.
Refrigerant Leaks
A refrigerant leak leads to low refrigerant levels, reducing your house’s cooling ability. It can also cause harm to the environment; hence, you need to address this issue immediately. You will need a professional to fix the refrigerant levels because it requires a specific kit, an EPA certification, and specialized knowledge.

Thermostat Malfunctioning
A failing thermostat can cause an uncomfortable atmosphere, whether too cold or too hot. If the thermostat is dirty or out of calibration, it can cause problems. Try cleaning the thermostat and readjusting the calibration by changing the settings. If the problem persists, it is advisable to replace it.
Drainage Problems
During usage, air conditioners produce condensate, which flows outside through a condensate drain. Over time, the condensate drain can become clogged, leading to water backing up and reaching the unit’s base. If left unchecked, water overflow can cause mold growth or rust. To fix this, clean the condensate drain to avoid accumulating dirt and mold.
Electrical Failure
An electrical failure can result from various reasons, such as wear and tear or a power surge. When this happens, your air conditioner will cease to operate. Your technician will need to diagnose which electrical component is failing and replace it.
Frozen Coils
A frozen coil can occur when the filter is clogged, resulting in improper airflow or leaking ducts. When the coil is frozen, the AC system can no longer function as intended, leading to overheating, increased electricity bills, and extensive damage. Defrosting the unit and fixing the airflow issues will resolve the issue.
Non-Functional Fan
A non-functional air conditioner fan can cause a lack of air circulation, so your house will not cool down effectively. It may also lead to compressor overheating, causing the unit to shut down automatically. A non-functional fan could result from burnt motor wires, faulty capacitors, or blocked airways. A technician can determine the problem and replace the non-functional parts to make the unit operational.
Clogged Condenser Coils
Condenser coils outside can get dirty and obstruct airflow, leading to compressor overheating and high head pressure, resulting in AC malfunction. You can identify this problem from loud hissing or noises from the unit. To fix this, clean the condenser coil at least once a year.
For a deeper understanding of air conditioner repair, it’s useful to explore the basics of common issues and their resolutions. Comprehensive guides and expert insights can provide valuable knowledge on maintaining your system and addressing potential problems effectively.
Short Cycling
Short cycling is when the air conditioner turns on and off frequently. The cooling process becomes ineffective when this happens, and the system can break down permanently. Short cycling could result from thermostat issues, clogged air filters, or faulty components. A technician can fix the underlying issues to help solve the problem.
Dirty Evaporator Coils
Dirty evaporator coils could result from a lack of maintenance and airflow issues, causing faulty cooling. Dirt and debris on the evaporator coils reduce the system’s efficiency by blocking the heat transfer process. The solution is cleaning the coil regularly or replacing it if necessary.
An air conditioner that is not working correctly can be a massive inconvenience, leading to discomfort and high electricity bills. Regular maintenance prevents many issues, but if you experience any of the above problems, it is best to act immediately to avoid further damage. However, some issues require professional assistance, so you should not hesitate to ask for help. Before summer hits, ensure your air conditioner is in good shape to beat the considerable heat and keep your family comfortable.
