Common AC Issues: Top Ten Problems And Their Root Causes

When the scorching summer heat arrives, the last thing you want is your air conditioning system malfunctioning. An efficiently functioning AC is essential for maintaining a comfortable indoor environment. However, AC problems are bound to occur over time for various reasons.

At Alief Ultra Mechanical, we understand the frustration and inconvenience caused by AC malfunctions, and we are here to provide top-notch AC repair in Houston, TX, and surrounding areas. Our experts can diagnose and repair any AC issue with ease.

Here are the ten most common AC problems, along with their causes:

Insufficient Cooling: One of the most common complaints homeowners have about their AC is insufficient cooling. Several factors could be at play if your AC fails to cool your space effectively. The most common causes include dirty air filters, low refrigerant levels, or a malfunctioning compressor. Regularly cleaning or replacing air filters, scheduling professional maintenance with us, and ensuring proper refrigerant levels can help alleviate this problem.

Airflow Issues: Inadequate airflow from your AC vents can result in discomfort and reduced cooling efficiency. Clogged or dirty air ducts, blocked vents, or a faulty blower fan can cause airflow issues. Regularly cleaning or replacing air filters, keeping vents unobstructed, and scheduling professional duct cleaning can help restore proper airflow.

Refrigerant Leaks: Refrigerant is responsible for cooling the air in your AC system. If you notice a decline in cooling performance, it could indicate a refrigerant leak. Common causes of leaks include corroded coils, loose fittings, or faulty valves. It is crucial to have a professional AC contractor like us in Houston, TX, repair the leak and recharge the refrigerant to prevent further damage to your system.

Strange Sounds: Unusual sounds from your AC unit can indicate an underlying problem. Rattling, banging, or squealing sounds may indicate loose or damaged components, a worn-out belt, or motor issues. Ignoring these sounds can lead to more significant problems. Contact our technician to diagnose and provide the best HVAC repair in Houston, TX, and surrounding areas.

Thermostat Problems: If your air conditioner fails to turn on, cycles frequently, or does not maintain a consistent temperature, the thermostat may be the culprit. Incorrect thermostat settings, faulty thermostat sensors, or wiring issues can disrupt the functioning of your AC system. Professional assistance can help identify and rectify these problems, ensuring proper thermostat functionality.

Frozen Evaporator Coil: A frozen evaporator coil is often caused by restricted airflow or low refrigerant levels. Insufficient airflow prevents the coil from absorbing heat, leading to ice buildup. Regular maintenance, including cleaning air filters and ensuring unobstructed airflow, can help prevent frozen evaporator coils. Contact us to schedule AC maintenance in Houston, TX, to keep your system in top condition.

Electrical Issues: Electrical problems can cause various AC malfunctions, including system failures, tripped circuit breakers, or blown fuses. Faulty wiring, loose connections, or overloaded circuits can harm your AC system and your home’s electrical infrastructure. Consulting an HVAC professional with electrical expertise is crucial to address these issues safely.

Malfunctioning Capacitors: Capacitors play a vital role in starting and running the motors in your AC system. Faulty capacitors can cause the AC to struggle to start or lead to intermittent cooling. Our professional technician can diagnose and replace malfunctioning capacitors, restoring proper function to your AC unit.

Dirty Condenser Coils: Condenser coils in your AC system are responsible for releasing heat outside. If these coils become dirty or covered in debris, it hampers heat transfer and reduces overall cooling efficiency. Regular maintenance can help prevent this problem and ensure optimal AC performance.

Clogged Drainage: AC units have a drainage system that removes condensation. Over time, the drain line can become clogged with dirt, debris, or algae, resulting in water leaks or even system shutdown. Clearing the drain line and ensuring proper drainage can prevent this issue.

If you are experiencing any of these problems, don’t hesitate to contact us for reliable HVAC repair in Houston, TX. Our experienced technicians will be happy to help you get your AC system back in good shape.
