Maintaining your air conditioning (AC) system is crucial for ensuring it operates efficiently and lasts for many years. At Gavin Mechanical, we understand the importance of regular maintenance in keeping your home comfortable and your energy bills low. Here are some essential maintenance tips to help you maximize your AC’s lifespan.

1. Regular Filter Changes

One of the simplest yet most effective ways to maintain your AC is by regularly changing its filters. Dirty filters restrict airflow, making the system work harder and reducing its efficiency. We recommend checking your filters monthly and replacing them every 1-3 months, depending on usage.

2. Clean the Coils

Over time, your AC's evaporator and condenser coils collect dirt, which can reduce their ability to absorb heat. To prevent this, clean the coils annually. If you notice significant dirt buildup, consider having a professional from Gavin Mechanical handle the cleaning.

3. Check the Thermostat

Ensure your thermostat is working correctly by testing it regularly. A malfunctioning thermostat can lead to incorrect temperature readings and inefficient cooling. Upgrading to a programmable thermostat can also help you save on energy costs by automatically adjusting the temperature when you're away.

4. Inspect the Refrigerant Levels

Low refrigerant levels can cause your AC to work harder and less efficiently, leading to potential damage. Have a professional technician from Gavin Mechanical check and top up your refrigerant levels during your annual maintenance visit.

5. Clear the Condensate Drain

A clogged condensate drain can cause moisture buildup, leading to increased humidity levels and potential water damage. Regularly inspect and clean the drain line to ensure it's free of obstructions.

6. Keep the Outdoor Unit Clean

The outdoor unit of your AC system can accumulate leaves, dirt, and debris, which can obstruct airflow and reduce efficiency. Keep the area around the unit clean and clear to ensure optimal performance. Trim any nearby vegetation to maintain at least two feet of clearance around the unit.

7. Schedule Professional Maintenance

While some maintenance tasks can be handled by homeowners, scheduling annual professional maintenance is crucial for your AC's longevity. Technicians from Gavin Mechanical can perform comprehensive inspections, cleanings, and tune-ups to keep your system running smoothly.

8. Seal and Insulate Your Ductwork

Leaky or poorly insulated ducts can cause significant energy loss, making your AC work harder. Inspect your ductwork for leaks and ensure it's properly insulated to improve efficiency and reduce strain on your system.



Regular maintenance is key to maximizing the lifespan and efficiency of your air conditioning system. By following these tips and scheduling annual professional maintenance with Gavin Mechanical, you can ensure your home stays cool and comfortable while keeping energy costs in check.
