    Proactive maintenance helps detect and address potential problems before they become major breakdowns. By conducting regular inspections and making necessary repairs, you can minimize the risk of sudden and costly AC system failures.

  • Warranty Compliance:

    Many AC manufacturers require regular inspections and maintenance to keep the warranty valid. Adhering to these requirements ensures you can take advantage of warranty coverage if any significant issues arise.

  • Cost Savings:

    Regular inspections and repairs can save you money in the long run. By maintaining your AC system’s efficiency, preventing major breakdowns, and extending its lifespan, you can avoid expensive repairs or the need for premature replacement.

Expert Tips for Keeping Your AC System Well-Maintained

Aside from routine repairs and inspections, there are other ways to ensure your system remains in peak shape and lasts for a long time. By following these tips, you can ensure that your air conditioning system operates efficiently and reliably, providing you with the comfort you need.

1. Have the thermostat calibrated.

The thermostat is the control center for your AC system, and properly calibrating it is essential for accurate temperature readings and efficient cooling. Over time, thermostats may become inaccurate due to dust buildup, electrical fluctuations, or mechanical issues. When the thermostat is incorrectly calibrated, it can lead to temperature inconsistencies and unnecessary energy consumption.


To have your thermostat calibrated, you can follow these steps:


  1. Ensure the thermostat is clean and free from dust or debris.
  2. Check the thermostat’s user manual for calibration instructions specific to your model.
  3. Typically, thermostat calibration involves adjusting the anticipator, which controls the timing of the system turning on and off.
  4. Use a small screwdriver or a calibration tool (if provided) to slightly adjust the anticipator setting.
  5. Test the thermostat by setting it to your desired temperature and monitoring the system’s response.


If you’re unsure about calibrating the thermostat yourself, it’s advisable to consult a professional HVAC technician. They have the expertise and specialized tools to accurately calibrate the thermostat and ensure it functions optimally.

2. Replace or clean the air filters.

Air filters play a vital role in trapping dust, dirt, allergens, and other airborne particles, preventing them from circulating throughout your home. Over time, these filters can become clogged with debris, restricting the airflow and making your AC system work harder to cool the space. This can lead to reduced efficiency, increased energy consumption, and potential strain on the system’s components.


Here’s a step-by-step guide for replacing or cleaning your air filters:


  1. Determine the type of air filter: Common types include fiberglass filters, pleated filters, electrostatic filters, and HEPA filters.
  2. Check the filter’s condition: If it appears dirty or clogged, it’s time to replace or clean it.
  3. Replacement: If you have a disposable filter, follow the manufacturer’s instructions to replace it with a new one. Make sure to use the correct size and type of filter for your system.
  4. Cleaning: If you have a washable or reusable filter, gently remove it from the unit. Rinse the filter with water to remove dirt and debris. Allow it to dry completely before reinstalling it.
  5. Frequency of maintenance: The frequency of filter replacement or cleaning depends on factors like the type of filter, the air quality in your area, and usage. As a general guideline, it’s recommended to replace or clean the filters every 1 to 3 months or as indicated by the manufacturer.

3. Keep your condensate drain clear. 

The condensate drain is responsible for removing the moisture that accumulates during the cooling process of your air conditioning system. Over time, the drain line can become clogged with dirt, debris, algae, or mold, leading to water backups, leaks, and potential damage to your AC unit or surrounding areas.

4. Remove obstructions.

Ensure the area around the condenser is free from obstructions like branches, leaves, and other debris. Obstructions can hinder airflow, reduce efficiency, and potentially cause damage to the air conditioning system. 

5. Clean the condenser coils.

Cleaning the condenser coils periodically can help guarantee debris and dirt won’t accumulate in the coils over time. You can use a gentle spray or a soft brush to clean the coils. Be extra careful when cleaning the condenser coils so you don’t damage them.

6. Lubricate the moving parts.

Lubricating the moving parts of your AC system is an important maintenance step that helps to reduce friction, minimize wear and tear, and ensure smooth operation. 


Proper lubrication prevents the components from overheating, extends their lifespan, and contributes to the system’s overall efficiency. Moving parts like the fan bearings and motors need to be lubricated based on the manufacturer’s recommendations. 

7. Check refrigerant levels.

Refrigerant is the substance responsible for absorbing heat from the indoor air and transferring it outside, enabling the cooling process. Insufficient refrigerant levels can lead to reduced cooling capacity, decreased energy efficiency, and potential damage to the system.


Have a seasoned and trusted professional check your AC’s refrigerant levels regularly to ensure they are correct. Low refrigerant levels can often indicate leaks or other AC problems that must be addressed.

8. Schedule professional maintenance.

Schedule an annual or bi-annual maintenance visit from a licensed and dependable technician. While there are several maintenance tasks that you can perform yourself, having a trained HVAC technician inspect and service your system ensures thorough maintenance.


A professional HVAC technician has the expertise to comprehensively inspect your AC system. They will examine all components, including the indoor and outdoor units, electrical connections, refrigerant levels, airflow, and overall system performance. Through this inspection, they can identify potential issues or areas requiring attention.

9. Invest in a programmable thermostat.

Upgrading to a smart thermostat for your AC system can greatly enhance its efficiency, comfort, and energy savings. A programmable thermostat allows you to set specific temperature levels based on your schedule, enabling your air conditioning system to operate more efficiently when you’re home and conserve energy when you’re away.


When selecting a programmable thermostat, consider the features and compatibility with your AC system. Some thermostats offer advanced functionalities such as learning capabilities, zoning control, or integration with smart home systems. Consult an HVAC professional to determine the best programmable thermostat option for your needs.

10. Adjust and monitor the air vents.

The air vents, also known as registers or grilles, are crucial in distributing cooled air throughout your living space. Regularly checking and adjusting them can ensure they stay open and unobstructed so you can enjoy consistent cooling throughout your home with less strain on your AC unit.

11. Protect your outdoor unit.

Protecting your outdoor AC unit, also known as the condenser unit, is crucial for maintaining its efficiency, performance, and longevity. The outdoor unit is exposed to various elements, such as weather, debris, and potential damage, which can affect its operation. Installing a protective cover or patio shade, especially during the off-season, can protect the outdoor unit’s lifespan from harsh conditions.


When it comes to maximizing your AC system’s return on investment (ROI), careful budgeting and proactive planning are key. Investing in regular AC inspections, maintenance, and repairs is a wise decision that ensures your system receives the necessary care to function optimally.


By considering the potential costs versus the long-term savings, it becomes evident that investing in air conditioning repairs and routine inspections is a financially wise move. While there may be upfront costs associated with inspections and maintenance, they are relatively small compared to the potential savings you can achieve. These savings come in the form of reduced utility bills, improved energy efficiency, and fewer instances of costly system replacements.
