As a homeowner, keeping your HVAC system in top condition is crucial for maintaining comfort and energy efficiency throughout the year. While professional services like Oakmont Mechanical are essential for major repairs and installations, there are several DIY maintenance tasks you can perform to keep your system running smoothly. In this article, we’ll explore some valuable tips to help you maintain your HVAC system and potentially avoid costly repairs.

Regular Filter Changes

One of the simplest yet most effective ways to maintain your HVAC system is by regularly changing or cleaning the air filters. This task should be performed every 1-3 months, depending on factors such as:

  • Pet ownership
  • Allergies in the household
  • Local air quality
  • Frequency of system use

Clean filters improve air quality, reduce energy consumption, and prevent unnecessary strain on your system.

Keep the Outdoor Unit Clean

Your AC’s outdoor unit needs attention too. Regularly inspect the area around the unit and remove any debris, leaves, or vegetation that may obstruct airflow. Gently clean the unit’s fins with a soft brush or vacuum to remove dirt and dust. This simple maintenance can significantly improve your system’s efficiency.

Check and Clean Vents

Ensure all vents and registers in your home are unobstructed by furniture, curtains, or other items. Vacuum the vents regularly to remove dust and debris. This not only improves air quality but also helps maintain proper airflow throughout your home.

Monitor Thermostat Function

Your thermostat plays a crucial role in your HVAC system’s performance. Regularly check its accuracy by comparing its reading to a separate thermometer. If you notice discrepancies, it may be time for a battery change or professional calibration. Consider upgrading to a programmable or smart thermostat for improved energy efficiency and comfort control.

Inspect Ductwork

While you may not be able to access all of your home’s ductwork, visually inspect the exposed sections for signs of damage, leaks, or disconnections. Sealing small leaks with duct tape can improve your system’s efficiency and air quality.

Maintain Proper Humidity Levels

Balancing humidity in your home is essential for comfort and HVAC efficiency. Use a hygrometer to monitor indoor humidity levels, aiming for a range between 30-50%. Consider using a dehumidifier in damp areas or a humidifier in dry conditions to maintain optimal levels.

Schedule Professional Maintenance

While these DIY tips are valuable, it’s important to remember that professional maintenance is still necessary. Schedule annual tune-ups with Oakmont Mechanical to ensure your system receives comprehensive care. Their experienced technicians can identify and address potential issues before they become major problems.


By following these DIY maintenance tips and partnering with Oakmont Mechanical for professional services, you can keep your HVAC system running efficiently year-round. Regular maintenance not only extends the life of your system but also helps maintain a comfortable and healthy home environment. Remember, while these tips are helpful, always consult with a professional for any concerns or major repairs to ensure the safety and longevity of your HVAC system.
