Why Isn't My AC Working?

As the scorching summer heat settles in, a malfunctioning air conditioning system can quickly turn your home or office into an uncomfortable and unbearable space—that's when you need air conditioner repair in Ardmore!

When your AC stops working, it's natural to feel frustrated and eager to find a solution. At Caldwell Mechanical Services, we understand the importance of a properly functioning cooling system. As HVAC specialists serving Oklahoma and Texas, we are here to help you understand the common reasons why your AC may not be working and provide guidance on how to address these issues effectively.

Thermostat problems:

One of the first things to check when your AC fails is the thermostat. Ensure that it is set to the appropriate temperature and mode (cooling). If the display is blank or unresponsive, check the batteries or consider replacing the thermostat. Faulty or outdated thermostats can prevent the AC from functioning correctly.

Clogged air filters:

Dirty and clogged air filters can significantly impact your AC's performance. Over time, dust, debris, and allergens accumulate in the filters, obstructing airflow and reducing cooling efficiency. Check your air filters regularly and clean or replace them as needed. This simple maintenance task can enhance the airflow and overall performance of your AC system.

Refrigerant leaks:

Insufficient refrigerant levels due to leaks can cause your AC to blow warm air. Refrigerant is responsible for cooling the air, and when levels are low, the system cannot produce the desired coolness. If you suspect a refrigerant leak, it's crucial to contact a professional HVAC technician. They have the expertise to locate and repair the leaks, recharge the refrigerant, and restore optimal cooling performance to your AC system.

Faulty compressor:

The compressor plays a vital role in the cooling process, as it pumps refrigerant through the system. If your AC is not providing cool air, a faulty compressor could be the culprit. Issues such as electrical problems, motor failure, or mechanical faults can cause the compressor to malfunction. Addressing compressor issues requires the expertise of an HVAC technician who can diagnose the problem accurately and recommend repair or replacement options.

Insufficient maintenance:

Lack of regular maintenance can lead to various AC problems. Neglecting to clean the coils, check electrical connections, or lubricate moving parts can result in reduced performance and even system breakdowns. To keep your AC running smoothly, it's essential to schedule annual maintenance visits with a professional HVAC specialist. Regular inspections, cleaning, and servicing will not only identify and resolve minor issues but also prolong the lifespan of your cooling system, improve energy efficiency, and ensure optimal cooling performance.

Tripped circuit breaker or blown fuse:

If your AC suddenly stops working, it's worth checking the electrical system. A tripped circuit breaker or blown fuse can disrupt the power supply to your cooling system. Locate the electrical panel in your home or office and check if the breaker for the AC unit has tripped or if any fuses related to the system have blown. If you find any issues, reset the breaker or replace the blown fuse. However, if the problem persists, it's advisable to consult a professional HVAC technician to address the underlying electrical problem.

Blocked condenser unit:

The condenser unit, typically located outside, plays a crucial role in dissipating heat from your AC system. If it becomes blocked or obstructed, the cooling process can be severely affected. Check for any debris, such as leaves, dirt, or vegetation, that may be blocking the condenser unit. Gently clean the area around the unit and remove any obstructions. It's also important to ensure that the condenser unit has sufficient clearance for proper airflow. If you suspect any damage or significant blockage, contact a professional HVAC technician to inspect and clean the condenser unit thoroughly.
