7 Preventative Measures To Minimise Air Conditioning Repair Needs

1. Regular Maintenance Checks

Schedule regular maintenance checks with a professional to ensure your air conditioning system operates efficiently. During these checks, technicians inspect all components, clean necessary parts, and identify potential issues before they escalate into serious problems.

Regular maintenance can extend the lifespan of your unit and improve its performance. It is recommended to have maintenance checks at least once a year, ideally before the start of the cooling season.

By addressing minor issues early, you prevent them from developing into costly repairs, ensuring your system remains reliable and efficient throughout the year.

2. Clean Or Replace Filters

Clean or replace air filters every one to three months to maintain proper airflow and system efficiency. Dirty filters restrict airflow and force the air conditioning system to work harder, which can lead to increased energy consumption and potential breakdowns.

Changing filters ensures clean air circulation, improves indoor air quality, and reduces the strain on your system. For homes with pets or in high-pollution areas, more frequent filter changes may be necessary.

A clean filter not only helps the system run more efficiently but also prolongs its lifespan, saving you money on energy bills and future repairs.

3. Inspect And Clean Coils

Ensure that both the evaporator and condenser coils are clean to maintain the efficiency of your air conditioning system. Over time, dirt and debris can accumulate on these coils, reducing their ability to absorb and release heat effectively.

Dirty coils cause the system to work harder, which leads to increased energy consumption and potential component failures. Regular cleaning, typically during annual maintenance checks, helps maintain optimal performance and energy efficiency.

Furthermore, clean coils ensure better heat exchange, lower energy bills, and a longer lifespan for your system. Maintaining them is crucial for preventing unnecessary wear and tear on your air conditioning unit.

4. Check Thermostat Settings

Verify that your thermostat settings are accurate and suited to your comfort needs. Incorrect settings can cause the air conditioning system to cycle on and off frequently, leading to increased wear and tear and higher energy bills.

Consider upgrading to a programmable thermostat for better control and energy efficiency. A programmable thermostat allows you to set different temperatures for various times of the day. This ensures optimal comfort while reducing unnecessary usage.

5. Clear Debris From Around The Unit

Keep the area around your outdoor unit free from debris such as leaves, grass, and other obstructions. These items can impede airflow, causing the system to work harder and potentially overheat.

Maintaining a clear space of at least two feet around the unit ensures proper airflow and efficient operation. Check the area on a regular basis and remove any debris that may accumulate. Proper airflow is essential for the system to release heat effectively, which is critical for maintaining optimal performance.

6. Ensure Proper Refrigerant Levels

Have a professional check the refrigerant levels in your air conditioning system regularly. Low refrigerant levels can cause the system to overheat and fail.

Proper refrigerant levels are also crucial for preventing damage to the compressor. If your system is low on refrigerant, it may indicate a leak that needs to be addressed immediately.

Periodic checks ensure that your system has the correct amount of refrigerant, which is vital for maintaining cooling efficiency and preventing strain on the unit.

7. Check And Tighten Electrical Connections

Over time, electrical connections within your air conditioning system can become loose. This may lead to potential system failures and safety hazards. Regularly check and tighten these connections to ensure reliable operation.

During routine maintenance checks, professionals will examine these connections to ensure they are secure and functioning correctly. Keeping electrical connections tight prevents unnecessary wear on the system and helps avoid costly repairs.

This simple yet crucial step enhances the overall reliability and safety of your air conditioning unit.
