Common AC Problems: Troubleshooting and Solutions

Is your sanctuary turning into a sauna despite your air conditioner running full tilt? It can be frustrating and uncomfortable when your AC starts acting up. 

In this comprehensive guide, we’ll delve into common AC problems, their root causes, and practical solutions to keep your excellent intact.

Why Is My Air Conditioner Not Cooling The House?

One of the most Common AC Problems people face is their ACs need to be more effective in cooling the house. 

This problem can stem from various factors, but a frequent culprit is a clogged air filter. When the filter is dirty, airflow is restricted, hindering the cooling process. 

Additionally, inadequate insulation or obstructions around the external unit can contribute to insufficient cooling.


To address these Common AC Problems, start by replacing or cleaning the air filter regularly. Aim to do it once a month during peak usage seasons to ensure optimal performance. 

Additionally, check for any obstructions around the external unit and ensure proper insulation in your home. 

If the problem persists, consider consulting with a professional technician to assess and rectify any underlying issues.

Your AC Is Constantly Turning On and Off

If your air conditioner keeps turning on and off more often than usual, it might be experiencing a problem called short cycling. 

This issue can cause higher energy usage and potential damage to the compressor. 

Short cycling can happen due to several reasons, such as having an oversized unit, low refrigerant levels, or a malfunctioning thermostat. 

Dirty evaporator or condenser coils can also lead to short cycling by disrupting the heat exchange process.


Contact a professional HVAC technician to assess and recalibrate your thermostat settings. Ensure your unit is appropriately sized for your living space to avoid unnecessary wear and tear. 

Address any refrigerant leaks promptly to maintain peak efficiency. Additionally, regular cleaning and maintenance of evaporator and condenser coils can prevent short cycling and optimize performance.

Your AC Won’t Turn On

Discovering that your AC refuses to kick into gear can be alarming, especially during scorching summer days. 

This problem might be linked to electrical issues, a malfunctioning thermostat, or a blown fuse. Faulty wiring or a malfunctioning capacitor can also prevent the AC from starting.


Start by checking the thermostat settings and ensuring it’s set to the desired temperature. If the problem persists, inspect the circuit breaker for a tripped fuse. 

Replace the fuse if needed, and if the issue persists, seek professional assistance for a thorough electrical inspection. 

A qualified technician can diagnose and repair any electrical issues or faulty components preventing your AC from turning on.

Your AC Is Not Blowing Cool Air

An air conditioner not blowing cool air is a paradoxical situation, and the cause is often related to refrigerant levels. 

A refrigerant leak or insufficient refrigerant can lead to warm air circulation. Additionally, dirty or blocked air ducts can restrict airflow, compromising cooling efficiency.


Engage a professional technician to inspect for leaks and recharge the refrigerant as needed. Regularly schedule maintenance to identify and address any potential issues before they escalate. 

Furthermore, ensure air ducts are clean and unobstructed to facilitate proper airflow. 

Regular duct cleaning and maintenance can improve indoor air quality and optimize cooling performance.

Your AC Is Having Drainage Issues

When your AC is not effectively draining moisture, it can result in water pooling around the unit, potentially causing damage. 

Clogged drain lines or a malfunctioning condensate pump are common culprits. Additionally, algae or mold growth within the drain lines can obstruct water flow.


Regularly clean the drain lines to prevent clogs and ensure proper drainage. If you notice standing water, consult a professional to assess and repair the condensate pump. Timely attention to drainage issues can prevent water damage and maintain your AC’s efficiency. Installing a condensate drain pan overflow switch can provide added protection against water damage by shutting off the unit in case of drainage problems.

Your AC Is Tripping the Circuit Breaker

Repeated tripping of the circuit breaker indicates an electrical problem within your AC system. This could be due to a short circuit, electrical overload, or a malfunctioning component. Common causes of circuit breaker trips include a dirty air filter, frozen evaporator coils, or a faulty compressor.


Avoid resetting the breaker multiple times without addressing the underlying issue, as it can lead to more significant problems. Contact a qualified technician to conduct a thorough electrical inspection and resolve the root cause. Regular maintenance and cleaning can prevent common AC Problems like dirty air filters or frozen coils, reducing the risk of circuit breaker trips and ensuring uninterrupted cooling comfort.

Your AC Is Making Strange Noises

Unusual sounds emanating from your AC can be disconcerting. Grinding, squealing, or banging noises may indicate issues with the fan motor, compressor, or other internal components. Loose or worn-out components can also cause rattling or vibrating noises.


Promptly turn off the AC and seek professional assistance to diagnose and repair the source of the noise. Ignoring strange sounds can lead to more extensive damage and higher repair costs. A qualified technician can perform a thorough inspection to identify the underlying issue and recommend appropriate repairs. Regular maintenance and timely repairs can prevent excessive wear and tear, prolonging the life of your AC and ensuring quiet and efficient operation.

Replace The Start/Run Capacitor(s)

Capacitors play a crucial role in the proper functioning of your AC compressor and fan motor. 

A malfunctioning capacitor can result in the unit not starting or running inefficiently. Over time, capacitors can weaken or fail due to heat, age, or electrical surges.

How To Replace A Capacitor

  • Turn off the power to the AC unit to prevent electrical shock.
  • Discharge any stored electricity by shorting the capacitor terminals with an insulated screwdriver.
  • Note the capacitor’s wiring and connections before removing it to ensure proper installation of the new capacitor.
  • Install the new capacitor by connecting the wires as per your previous notes. Take care to match the correct terminals to prevent damage.
  • Turn the power back on and test the AC to ensure proper operation. Monitor the unit for any unusual noises or behavior that may indicate further issues.

How To Test Your Repairs

After making any repairs or replacements, it’s crucial to test your AC to ensure everything is functioning correctly. Follow these steps to verify the effectiveness of your repairs:

  • Gradually lower the thermostat setting to trigger the AC to turn on.
  • Listen for any unusual noises during the startup process, such as grinding, squealing, or banging sounds.
  • Monitor the temperature in your home to ensure the AC is cooling effectively. Use a thermometer to measure the temperature at different locations around your home and provide consistent cooling throughout.
  • Check the airflow from the vents to ensure it’s solid and consistent. Weak airflow may indicate underlying issues with the ductwork or blower motor.
  • Monitor the AC’s performance over the next few days to ensure the problem has been resolved. If you notice any recurring issues or unusual behavior, contact a professional technician for further inspection and repairs.
