Common DIY Air Conditioner Repairs

Common DIY Air Conditioner Repairs

When your air conditioner suddenly stops working or starts to malfunction, it can be frustrating and inconvenient. However, before calling a professional technician, there are a few common air conditioner repairs that you can try to fix the issue yourself. In this article, we will discuss some DIY air conditioner repairs that you can attempt before seeking professional help.

Cleaning or Replacing the Air Filter

One of the most common causes of air conditioner problems is a dirty or clogged air filter. Over time, the air filter can become filled with dust, dirt, and debris, which restricts the airflow and reduces the efficiency of your air conditioner. To fix this issue, locate the air filter, which is usually located in the return air duct or inside the air handler unit. Remove the filter and clean it with mild soap and water. If the filter is damaged or too dirty to clean, replace it with a new one.

Checking and Cleaning the Condenser Unit

The condenser unit, located outside your home, plays a crucial role in cooling the air. Over time, the condenser coils can become dirty and covered in debris, which hampers the heat transfer process. To clean the condenser unit, turn off the power supply to the air conditioner and remove any large debris, such as leaves or twigs, from the unit. Then, gently spray the condenser coils with a garden hose to remove any dirt or dust buildup. Be careful not to use too much pressure, as this could damage the delicate fins.

Checking and Replacing the Capacitor

The capacitor is a small electronic component that helps start the compressor and fan motor in your air conditioner. If the capacitor fails, your air conditioner may not start or may not cool effectively. To check the capacitor, turn off the power supply to the air conditioner and locate the capacitor, which is usually housed in a metal or plastic box near the condenser unit. Inspect the capacitor for any signs of bulging, leaking, or damage. If you notice any issues, replace the capacitor with a new one of the same rating.

Checking and Cleaning the Evaporator Coils

The evaporator coils are located inside the air handler unit and are responsible for absorbing heat from the air. Over time, these coils can become dirty and covered in dust and debris, which reduces their efficiency. To clean the evaporator coils, turn off the power supply to the air conditioner and remove the access panel to expose the coils. Gently brush off any visible dirt or dust using a soft brush. If the coils are heavily soiled, you may need to use a coil cleaner solution to remove the buildup.

Checking the Thermostat

Another common issue that can cause air conditioner problems is a faulty thermostat. If your air conditioner is not cooling properly or is not turning on, check the thermostat settings to ensure they are correct. Make sure the thermostat is set to “cool” and the temperature is set lower than the current room temperature. If the thermostat is not working correctly, replace it with a new one.

HVAC DIY maintenance can seem like a daunting task and knowing when to DIY and when to call a repairman can be overwhelming. While most HVAC issues should be serviced by a professional, there are a few things that you can do to maintain your system.

It is recommended to have a professional service your HVAC unit before each cooling season, however there are a few do-it-yourself air conditioning repairs you can do yourself. Replacing and cleaning the indoor unit’s air filter every month is an easy DIY item for any homeowner. Check your owner’s manual to make sure you are cleaning it appropriately. You should also occasionally remove any debris from around the outside condenser unit to maximize airflow.

Additional DIY air conditioner repairs may include cleaning the coils and fan blades at the start of the cooling season. Be sure to consult your owner’s manual to see how to properly clean these parts, and remember to shut off the power to the unit before performing any maintenance.

As temperatures drop, continue to clean or change your filter each month and check all connections and ductwork to the units. Any damaged ductwork or exposed electrical connections need to be replaced right away by an American Standard Customer Care Dealer. A malfunctioning unit can drive up your heating bills and lead to more expensive repairs if not addressed immediately.

Preparing your HVAC system for peak seasons is important, which is why you should have an American Standard Customer Care dealer, service your system at least once a year. These regular checkups can help to prevent larger issues and keep your system running smoothly year round.

Conclusion

While these DIY air conditioner repairs can help resolve common issues, it’s important to remember that not all problems can be fixed without professional help. If your air conditioner continues to have issues or if you are unsure about performing any repairs yourself, it’s best to contact a qualified HVAC technician. They have the knowledge and expertise to diagnose and fix complex air conditioner problems, ensuring your system operates efficiently and effectively.
