Inspect and Replace Air Filters

One of the simplest yet most crucial maintenance tasks is inspecting and replacing air filters. Dirty or clogged filters can strain your system and decrease efficiency. It's recommended to check your filters every 1-3 months, especially during peak usage periods.

  • Turn off the unit before inspecting the filter.
  • If the filter appears dirty, replace it with a new one.
  • Consider using high-efficiency filters for better air quality.

Understanding Filter Types

Filters come in various types, including fiberglass, pleated, and HEPA. Fiberglass filters are the most affordable but need frequent replacements, while pleated and HEPA filters offer better filtration and last longer.

Clean the Condenser Coils

The condenser coils, located in the outdoor unit, play a vital role in cooling the air. Over time, dirt and debris can accumulate, reducing efficiency. Cleaning these coils is a straightforward process that can improve your system's performance.

  1. Turn off the power to the unit.
  2. Use a garden hose to gently wash away dirt and debris.
  3. Avoid using high-pressure water to prevent damage.

Maintain the Area Around the Unit

Ensure the area around the outdoor unit is clear of obstructions. Trim back foliage and remove debris to promote proper airflow. Keeping the unit unobstructed prevents excessive strain on the system.

Check and Clean the Evaporator Coil

Located inside, the evaporator coil absorbs heat and is essential for effective cooling. Dust and grime can accumulate, so regular cleaning is necessary. This task may require professional assistance if you're unfamiliar with the process.

For DIY cleaning:

  • Turn off the unit's power.
  • Access the coil by removing any panels or covers.
  • Use a soft brush to gently clean the coil.

Conclusion

By following these DIY tips, New Jersey homeowners can ensure their air conditioning systems remain efficient and reliable. Regular maintenance reduces the likelihood of costly repairs and keeps your home comfortable throughout the summer. Don't hesitate to consult a professional if you're unsure about any maintenance steps.
