Common Causes of Air Conditioning Breakdowns in Tempe's Extreme Heat

Extreme heat puts a lot of pressure on air conditioning systems. While ACs are designed to keep homes cool, prolonged periods of intense heat can lead to malfunctions and breakdowns. Here are the most common causes of AC problems during heatwaves in places like Tempe.

Restricted Airflow

Air filters are essential elements for AC efficiency. When filters get clogged, airflow is restricted, making the AC work harder and causing overheating and malfunctions. Cleaning or replacing air filters regularly, especially during peak usage, is essential for optimal performance.

Inefficient Heat Rejection

Condenser coils located outside release heat extracted from your home. When these coils get covered in leaves, debris, or dust, their ability to release heat is reduced. This forces the AC to work overtime, increasing the risk of breakdowns. Cleaning the condenser coils regularly can help maintain efficient operation.

Refrigerant Depletion

Refrigerant is vital for an AC system. Low refrigerant levels mean the AC cannot absorb enough heat, leading to inadequate cooling and breakdowns. Leaks or improper AC installation can cause refrigerant depletion. Qualified technicians can examine and fix refrigerant issues to ensure proper system function.

Frozen Coils

Dirty evaporator coils inside the unit can freeze even during a heatwave. This happens when airflow is restricted by clogged filters or low refrigerant levels. Frozen coils block cool air circulation, reducing comfort levels. Regular cleaning and professional AC maintenance can prevent frozen coil issues.

Thermostat Malfunctions

If the thermostat is faulty, it can send incorrect signals, causing the system to run continuously or not at all. If your AC isn't responding as expected, check the thermostat settings and batteries first. Persistent issues might require replacing the thermostat.

Drainage Issues

AC systems produce condensation that needs proper drainage. A clogged drain line can cause water buildup, which can damage internal components. Ensuring a clear, unobstructed drain line is vital to prevent water overflow and related malfunctions.

Fan Failure

Functional fans are important for air circulation within the AC system. A poorly functioning fan can disrupt airflow, straining the system and leading to overheating. Unusual noises or uneven airflow might indicate fan problems.

Preventive Maintenance

A proactive maintenance plan can reduce the risk of breakdowns and extend your AC's lifespan:

• Schedule annual professional AC checkups for cleaning, inspection, and minor adjustments.
• Keep a consistent air filter cleaning or replacement schedule.
• Clear the condenser unit of debris and foliage regularly.
• Monitor AC performance and address any minor issues promptly.
