Essential DIY Tips for Maintaining Your HVAC System Year-Round


Keeping your home comfortable throughout the year is crucial, especially in the warm climates of Naples, Marco Island, Lely, Golden Gate, Vineyards, and Bonita Springs, Florida. While professional air conditioner service is essential, there are several DIY steps you can take to maintain your HVAC system’s efficiency and longevity. Accurate Comfort Services is here to provide you with valuable tips to keep your cooling system running smoothly.

Regular Filter Changes

One of the simplest yet most effective ways to maintain your air conditioning 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 and allergies. Clean filters ensure:

  • Better air quality
  • Improved energy efficiency
  • Reduced strain on the system

Keep the Outdoor Unit Clean

Your AC’s outdoor unit needs attention too. Ensure the area around the unit is clear of debris, leaves, and vegetation. Gently clean the unit’s fins with a soft brush or vacuum to remove dirt and dust. This simple maintenance task can significantly improve your system’s performance.

Check and Clean Condensate Drain Line

The condensate drain line can become clogged with algae and mold, leading to water damage and reduced efficiency. Regularly pour a cup of white vinegar or bleach down the drain to prevent blockages. If you notice standing water around your indoor unit, it’s time to call for professional air conditioning repair.

Inspect and Seal Ductwork

Leaky ducts can waste up to 30% of your cooled air. Inspect visible ductwork for gaps or disconnections, and seal them with mastic sealant or metal tape. This DIY task can significantly improve your system’s efficiency and reduce energy bills.

Maintain Proper Thermostat Settings

Programming your thermostat correctly can save energy and reduce wear on your system. During summer months in Florida, set your thermostat to 78°F when you’re home and higher when you’re away. Consider upgrading to a smart thermostat for more precise control and energy savings.

Keep Vents Clear and Open

Ensure all supply and return vents are unobstructed by furniture, drapes, or other objects. This allows for proper airflow throughout your home, reducing strain on your AC system and maintaining consistent temperatures.

Schedule Professional Maintenance

While these DIY tips are valuable, they don’t replace the need for professional HVAC maintenance. Schedule annual tune-ups with Accurate Comfort Services to ensure your system receives comprehensive care, including:

  • Refrigerant level checks
  • Electrical component inspections
  • Coil cleaning
  • Lubrication of moving parts

Monitor Your Energy Bills

Keep an eye on your energy bills. A sudden increase could indicate your AC system is working harder than necessary, possibly due to a developing issue. Early detection can prevent costly repairs down the line.


By following these DIY tips and scheduling regular professional maintenance, you can ensure your HVAC system operates efficiently year-round. Remember, while these tasks can help maintain your system, any major repairs or persistent issues should be addressed by the certified technicians at Accurate Comfort Services.
